    Correct

    • A 32-year-old G3P2 female presents to your department for prenatal check up. She is in the 26th week of gestation and her pregnancy has been uneventful so far. Her past medical history is unremarkable. Her second child was born macrosomic with shoulder dystocia, which was a very difficult labour.
      Which of the following is the most appropriate management of this patient?

      Your Answer: Watchful waiting till she goes in labour

      Explanation:

      Shoulder dystocia is a complication associated with fetal macrosomia and may result in neurological dysfunction. Fetal macrosomia is generally defined as birth weight – 4,000 g. It occurs in about 10% of pregnancies and one of the most important predictors of fetal macrosomia is previous macrosomic infant(s). The recurrence rate of fetal macrosomia is above 30%. Other risk factors are maternal diabetes, multiparity, prolonged gestation, maternal obesity, excessive weight gain, male foetus, and parental stature- Not all cases of fetal macrosomia lead to shoulder dystocia and the occurrence of this complication is only 0.5%-1% of all pregnancies.

      To make clinical decision regarding management of the patient, it is important to understand that there are other factors that lead to shoulder dystocia, such as the mother’s anatomy. While statistics suggest that there’s a tendency to choose elective Caesarean delivery for suspected macrosomia, it is believed that most of procedures are unnecessary, as evidence has shown the number of complications are not reduce- Also while it is logical to consider induction of labour at the 37th week of pregnancy, it is associated with increased Caesarean deliveries because of failed inductions. The recommended course of action is watchful waiting till the patient goes in labour.

      → Induce labour at the 37th week of gestation is not the best course of action, as it is associated with high failure rate, which often leads to Caesarean delivery.
      → Schedule elective Caesarean delivery is considered unnecessary in patients who do not have diabetes. Statistics have shown no evidence that Caesarean delivery reduces the rate of complications.
      → Serial ultrasound for fetal weight estimation is incorrect. The strategies used to predict fetal macrosomia are risk factors, Leopold’s manoeuvres, and ultrasonography. Even when they are combined, they are considered inaccurate; much less ultrasonography alone.
      → At this point, blood glucose control in pregnancies associated with diabetes seems to have desired results in preventing macrosomia- A weight loss program is usually not recommended- Instead, expectant management should be considered.

    Correct

    • A 27-year-old nulliparous woman presents with the complaint of malodorous vaginal discharge for the past one month. Patient has tried various over-the-counter vaginal douche products without any improvement.  Her last menstrual period was 2 weeks ago, during which she noticed no change in her symptoms. In addition to the discharge, patient also experiences intermittent, crampy abdominal pain along with a feeling of gas passing through her vagina. Patient has had no history of surgeries in the past.

      On examination her vital signs seems to be normal.  Speculum examination shows a malodorous, tan vaginal discharge with an erythematous patch over the posterior vaginal wall. The cervix is nulliparous and has no visible lesions or areas of friability. A sinus with purulent drainage is found in the perianal skin. 

      Which among the following conditions will be the most likely underlying cause for this patient’s presentation?

      Your Answer: Transmural inflammation of the bowel

      Explanation:

      Common risk factors for Rectovaginal fistula are Pelvic radiation, Obstetric trauma, Pelvic surgery, Colon cancer, Diverticulitis and Crohn disease. Uncontrollable passage of gas &/or feces from the vagina is considered the common clinical feature of Rectovaginal fistula.
      Diagnosis is done with the help of physical examination, fistulography, Magnetic resonance imaging and Endosonography.

      This patient, mentioned in the case, presents with malodorous vaginal discharge (ie, stool), gas passing through the vagina, and a posterior vaginal lesion most likely has a rectovaginal fistula, which is an aberrant connection between bowel and vagina.  Although development of rectovaginal fistula is commonly associated with obstetric trauma or pelvic surgery, patients without these risk factors are recommended to be evaluated for other additional causes like gastrointestinal conditions.
      This patient’s intermittent, crampy abdominal pain and perianal sinus in the setting of a rectovaginal fistula is most likely due to an underlying Crohn disease.  Crohn disease, is a transmural inflammation of the gastrointestinal tract, which predisposes patients to bowel abscess, fissure, and fistula formation.  Although the rectum is typically spared in Crohn disease, a non-healing, transmural ulcer present in the anal canal can progress to form a rectovaginal fistula.
      In addition to standard Crohn disease management like anti-TNF inhibitors, glucocorticoids, etc patients with a rectovaginal fistula may require surgical correction.

      Bartholin gland cysts or abscesses can present with malodorous vaginal discharge; however, patients typically have a posterior vulvar mass located at the 4 or 8 o’clock position. In addition, Bartholin gland cysts will not present with crampy abdominal pain or passage of flatus or stool through the vagina.

      Hidradenitis which is the chronic occlusion and inflammation of hair follicles, can cause groin abscesses with sinus tracts and associated purulent drainage.  However, it is not associated with abdominal pain or malodorous vaginal discharge. In addition, this condition is typically multifocal and located in more than one intertriginous areas like axillary, inguinal or gluteal regions.

      Cervical cancer or a retained foreign body in the vagina can cause malodorous vaginal discharge and abdominal pain.  However, patients will typically have visible findings like cervical lesion, foreign body etc on speculum examination, and these neither are associated with the passage of flatus through the vagina.

      Complications of Crohn disease include perianal disease like abscess, fissure and fistula like rectovaginal fistula, due to transmural inflammation of the gastrointestinal tract.  Patients with a rectovaginal fistula typically presents with malodorous, tan vaginal discharge, passage of flatus through the vagina and a posterior vaginal lesion.

    Correct

    • A 28-year-old, currently at 26 weeks’ gestation of her third pregnancy, presents with irregular uterine contractions for the past 24 hours and has concerns about premature delivery. She delivered her first child at 38 weeks of gestation and her second at 39 weeks gestation. On examination, BP and urinalysis have come back normal. Her symphysis-fundal height measures 27cm, the uterus is lax and non-tender. Fetal heart rate is 148/min. She also undergoes a pelvic examination along with other investigations.

      Which findings would suggest that delivery is most likely going to happen before 30 weeks’ of gestation?

      Your Answer: The cervix is closed, but the fetal fibronectin test on cervical secretions is positive.

      Explanation:

      Predisposing factors of preterm delivery include a short cervix (or if it shortens earlier than in the third trimester), urinary tract or sexually transmitted infections, open cervical os, and history of a previous premature delivery. Increased uterine size can also contribute to preterm delivery and is seen with cases of polyhydramnios, macrosomia and multiple pregnancies. The shorter the cervical length, the greater the risk of a premature birth.
      In this case, the risk of bacterial vaginosis and candidiasis contributing to preterm delivery would be lower than if in the context of an open cervical os. However, the risk of premature delivery is significantly increased if it is found that the fetal fibronectin test is positive, even if the os is closed.

    Correct

    • All of the following factors are associated with an unstable lie of the foetus except?

      Your Answer: Cervical fibroids

      Explanation:

      Unstable lie means that the foetus is still changing its position even at 36 weeks of gestation. A number of factors are responsible for this positioning such as multi gravida, placenta previa, prematurity and fibroids present in the fundus. Cervical fibroids have little association with unstable lie of the foetus.

    Correct

    • A 20-year-old nulligravid woman comes to the office for a routine checkup, as she is concerned about having gained 4.5 kg over the last year. She believes that the gain is related to her oral contraceptive pills. 

      Patient takes low-dose ethinyl estradiol
      orethindrone daily. Prior to starting the pills, she had regular but heavy periods lasting for 4-5 days.  Patient used to miss her school every month, on the first day of her period, due to severe cramping. Her pain symptoms resolved 3 months after starting the pills and she takes no other medications.  Patient's coitarche was at the age of 18 and she has had 2 partners since then. Patient and her current partner use condoms inconsistently. 

      On examination her vital signs are normal, with a BMI of 27 kg/m2 and physical examination is unremarkable. 

      Among the following which is the most appropriate advice for this patient?

      Your Answer: Reassure that the weight gain is not related to combined OCPs

      Explanation:

      Breakthrough bleeding, breast tenderness, nausea, bloating, amenorrhea, hypertension, venous thromboembolic disease, increased risk of cervical cancer with decreased risk of ovarian & endometrial cancer, liver disorders like hepatic adenoma and increase in triglycerides due to estrogen component are the common side effects & risks of using combination oral contraceptives.

      Patient in the given case mentioned symptoms of primary dysmenorrhea, which is recurrent lower abdominal pain associated with menstruation. Combination estrogen-progestin oral contraceptive pills (OCPs) are considered as the first-line treatment for dysmenorrhea in sexually active patients as OCPs help to reduce pain by thinning the endometrial lining, reducing prostaglandin release and by decreasing uterine contractions.
      Nausea, bloating and breast tenderness, are considered as the early side effects of OCPs and will usually improve with continued use. The most common side effect is breakthrough bleeding which is usually associated with lower estrogen doses and other adverse effects caused by the pills include hypertension, increased risk of cervical cancer and venous thromboembolism. Although common perception considers weight gain as a side effect, several studies have shown that no significant weight gain is associated with OCPs, particularly with low-dose formulations.  Considering this, the patient should be reassured that her weight gain is not associated with regular use of OCPs.

      In patients who are not sexually active, nonsteroidal anti-inflammatory drugs are considered as the first-line treatment for primary dysmenorrhea. As stopping contraception will increase this Patient’s risk of unintended pregnancy this is not advisable to her.

      Switching the patient to a copper intrauterine device (IUD) will decrease systemic side effects, but as its inflammatory reaction in the uterus may increase pain symptoms, copper IUD is not recommended for patients with dysmenorrhea.

      As Medroxyprogesterone will increase body fat and decrease lean muscle mass resulting in weight gain is not a good option for this patient. Also medroxyprogesterone due to its risk of significant loss of bone mineral density, is not recommended for adolescents or young women. So it can be used in this age group only if other options are unacceptable.

      Presence of estrogen component is the main reason behind the side effects of combination OCPs. Progesterone-only pills have relatively fewer side effects but as they do not inhibit ovulation, they are less effective for treating dysmenorrhea and for contraception.

      Combination oral contraceptive pills are the first-line therapy for primary dysmenorrhea in sexually active patients.  Its side effects include breakthrough bleeding, hypertension, and increased risk of venous thromboembolism. Researches proves that weight gain is usually not an adverse effect of OCPs.

    Correct

    • A 35-year-old woman from the countryside of Victoria comes to the hospital at 37 weeks of gestation after noticing a sudden gush of clear fluid from her vagina.

      Speculum examination shows pooling of liquor in the posterior fornix and patient developed fever, tachycardia and chills 12 hours after this episode.

      Apart from giving antibiotics, what will be your strategy in management of this case?

      Your Answer: Induce labour now

      Explanation:

      Above mentioned patient presented with symptoms of premature rupture of membranes (PROM) which refers to membrane rupture before the onset of uterine contractions.

      A sudden gush of clear or pale yellow fluid from the vagina is the classic clinical presentation of premature rupture of membranes. Along with this the patient also developed signs of infection like fever, tachycardia and sweating which is suggestive of chorioamnionitis.

      Vaginal examination is never performed in patients with premature rupture of membrane, instead a speculum examination is the usually preferred method which will show fluid in the posterior fornix.

      The following are the steps in management of premature rupture of membrane:
      – Admitting the patient to hospital.
      – Take a vaginal
      ervical smears.
      – Measure and monitor both white cell count and C- reactive protein levels.
      – Continue pregnancy if there is no evidence of infection or fetal distress.
      – In presence of any signs of infection or if CTG showing fetal distress it is advisable to induce labour.
      – Corticosteroids must be administered if delivery is prior to 34 weeks of gestation.
      – Give antibiotics as prevention and for treatment of infection.

    Correct

    • A 27-year-old woman presents for difficulty and pain in attempting sexual intercourse. She states that she never had such symptoms prior. The pain is not felt at the time of penetration, but appears to hurt deeper in the vagina.

      She was recently pregnant with her first child and delivery was three months ago. She did not have an episiotomy or sustain any vaginal lacerations during delivery. She denies any vaginal bleeding since her lochia had stopped two months ago. She is still breastfeeding her child.

      Which of the following is the most likely cause of her dyspareunia?

      Your Answer: Atrophic vaginal epithelium.

      Explanation:

      This is a patient that recently gave birth and is still breastfeeding presenting with dyspareunia. The most likely cause would be a thin atrophic vaginal epithelium. This is very common presentation and is due to the low oestrogen levels due to the prolactin elevation from breastfeeding.

      An unrecognised and unsutured vaginal tear should have healed by this time and should not be causing issues.

      Endometriosis tends to resolve during a pregnancy, but if this was the issue, it would have caused dyspareunia prior to pregnancy.

      Vaginal infective causes of dyspareunia, such as monilial or trichomonal infections, are rare in amenorrhoeic women.

    Incorrect

    • A 37-year-old primigravid woman is admitted to labor unit at 39 weeks of gestation, due to regular uterine contractions. Her cervix is 8 cm dilated and 100% effaced, with the fetus’ vertex at +1 station. Initially the fetal heart rate was 150 bpm, as the labor progressed, it falls to 80 bpm without any changes in the mother’s general condition.
      Which among the following options would be the best next step in management of this case?

      Your Answer: Vaginal examination to exclude any cord prolapse

      Correct Answer: Cardiotocography

      Explanation:

      Bradycardia of <100 bpm for more than 5 minutes or <80 for more than 3 minutes is always considered abnormal. The given case describes fetal bradycardia detected on fetal heart auscultation and the most common causes for severe bradycardia are prolonged cord compression, cord prolapse, epidural and spinal anesthesia, maternal seizures and rapid fetal descent. Immediate management including identification of any reversible causes for the abnormality and initiation of appropriate actions like maternal repositioning, correction of maternal  hypotension, rehydration with  intravenous fluid,  cessation of oxytocin, tocolysis for excessive uterine activity, and initiation or maintenance of continuous CTG should be considered in clinical situations where abnormal fetal heart rate patterns are noticed. Consideration of further fetal evaluation and delivery if a significant abnormality persists are very important. The next step in this scenario where the baby is in 1+ station, with an abnormal fetal heart rate detected on auscultation would be to perform a confirmatory cardiotocography (CTG) and if the CTG findings confirm the condition despite initial measures obtained, prompt action should be taken. Cord compression or prolapse should come on the top of the differential diagnoses list as the the mother shows normal general conditions, but since the cervix is 8 cm dilated, 100% effaced and the fetal head is already engaged, cord prolapse would be unlikely; therefore, repeating vaginal exam is not as important as confirmatory CTG. However a vaginal exam should be done, if the scenario indicates any possibility of cord prolapse, to exclude cord compression or prolapse. NOTE– In cases of severe prolonged bradycardia, immediate delivery is recommended, if the cause cannot be identified and corrected.

    Correct

    • A 32-year-old woman, gravida 2 para 1, at 40 weeks gestation is admitted to the hospital due to contractions and spontaneous rupture of membranes. Patient underwent a cesarean delivery with her first child due to breech presentation, but this pregnancy has been uncomplicated. She has no chronic medical conditions and is taking only a prenatal vitamin. 

      Her pre-pregnancy BMI was 20 kg/m2 and she has gained 15.9 kg (35 lb) during pregnancy.  On examination her blood pressure is found to be 130/80 mm Hg. 

      The patient is admitted and epidural anesthesia is administered with an intrauterine pressure catheter in place. She quickly dilates to 10 cm with the fetal vertex at 0 station, occiput transverse.  Four hours later, the pelvic examination is unchanged but there is molding and caput on the fetal head.  Fetal monitoring is category I.  Contractions occur every 2-3 minutes and the patient pushes with each contraction.  The contraction strength is an average of 210 MVU every 10 minutes. 

      Which among the following is most likely the etiology for this patient’s clinical presentation?

      Your Answer: Fetal malposition

      Explanation:

      Condition where there is insufficient fetal descent after pushing for ≥3 hours in nulliparous and ≥2 hours if multiparous women is defined as Second stage arrest of labor. Common risk factors for this presentation are maternal obesity, excessive weight gain during pregnancy and diabetes mellitus. Cephalopelvic disproportion, malposition, inadequate contractions and maternal exhaustion are the common etiologies of Second stage arrest of labor. Management includes Operative vaginal delivery or cesarean delivery as indicated in the case.

      The second stage of labor begins with the dilatation of cervix to 10 cm and will end with fetal delivery. Parity and use of neuraxial anesthesia are the two factors which will affect the duration of second stage of labor and fetal station, which measures the descent of the fetal head through the pelvis determines its progression.

      When there is no fetal descent after pushing for ≥3 hours or ≥2 hours in in nulliparous and multiparous patients respectively the condition is called an arrested second stage of labor. As her first delivery was a cesarean session due to breech presentation, this patient in the case is considered as nulliparous.

      Most common cause of a protracted or arrested second stage is fetal malposition, which is the relation between the fetal presenting part to the maternal pelvis. Occiput anterior is the optimal fetal position as it facilitates the cardinal movements of labor, any deviations from this position like in occiput transverse position, can lead to cephalopelvic disproportion resulting in second stage arrest.
      Inadequate contractions, that is less than 200 MVU averaged over 10 minutes, can lead to labor arrest but contractions are adequate in case of the patient mentioned.
      Second stage arrest can be due to maternal obesity and excessive weight gain during pregnancy but this patient had a normal pre-pregnancy BMI of 20 kg/m2 and an appropriate weight gain of 15.9 kg 35 lb. So this also cannot be the reason.

      Maternal expulsive efforts will change the fetal skull shape. This process called as molding helps to facilitate delivery by changing the fetal head into the shape of the pelvis. Whereas prolonged pressure on head can result in scalp edema which is called as caput, presence of both molding and caput suggest cephalopelvic disproportion, but is not suggestive of poor maternal effort.

      Patients with a prior history of uterine myomectomy or cesarean delivery are at higher risk for uterine rupture.  In cases of uterine rupture, the patient will present with fetal heart rate abnormalities, sudden loss of fetal station (eg, going from +1 to −3 station) along with fetal retreat upward and into the abdominal cavity through the uterine scar due to decreased intrauterine pressure. In the given case patient’s fetal heart rate tracing is category 1 and fetal station has remained 0 which are non suggestive of uterine rupture.

      When there is insufficient fetal descent after pushing ≥3 hours in nulliparous patients or ≥2 hours in multiparous patients is considered as second stage arrest of labor. The most common cause of second stage arrest is cephalopelvic disproportion, were the fetus presents in a nonocciput anterior position called as fetal malposition.

    Correct

    • Management of a patient with threatened abortion includes all of the following, EXCEPT:

      Your Answer: Dilatation and curettage

      Explanation:

      Patients with a threatened abortion should be managed expectantly until their symptoms resolve. Patients should be monitored for progression to an inevitable, incomplete, or complete abortion. Analgesia will help relieve pain from cramping. Bed rest has not been shown to improve outcomes but commonly is recommended. Physical activity precautions and abstinence from sexual intercourse are also commonly advised. Repeat pelvic ultrasound weekly until a viable pregnancy is confirmed or excluded. A miscarriage cannot be avoided or prevented, and the patients should be educated as such. Intercourse and tampons should be avoided to decrease the chance of infection. A warning should be given to the patient to return to the emergency department if there is heavy bleeding or if the patient is experiencing light-headedness or dizziness. Heavy bleeding is defined as more than one pad per hour for six hours. The patient should also be given instructions to return if they experience increased pain or fever. All patients with vaginal bleeding who are Rh-negative should be treated with Rhogam. Because the total fetal blood volume in less than 4.2 mL at 12 weeks, the likelihood of fetal blood mixture is small in the first trimester. A smaller RhoGAM dose can be considered in the first trimester. A dose of 50 micrograms to 150 micrograms has been recommended. A full dose can also be used. Rhogam should ideally be administered before discharge. However, it can also be administered by the patient’s obstetrician within 72 hours if the vaginal bleeding has been present for several days or weeks.

    • An otherwise healthy 21 year old primigravida comes to your office for a routine visit at 16 weeks gestation. She has had a normal pregnancy to date, and her only medication is a multivitamin with 0.4 mg folic acid. You order a maternal serum alpha-fetoprotein level. Adjusted for gestational age, maternal weight, and race, the results are significantly elevated. Which one of the following would you now recommend?

      Your Answer: Fetal ultrasonography

      Explanation:

      A 16-week visit is advised for all pregnant women to offer an alpha-fetoprotein (AFP) screening for neural tube defects and Down syndrome- An AFP level 2-5 times the median value for normal controls at the same gestational age is considered elevate- Approximately 5%-10% of patients who undergo AFP screening will have an elevated level, and most of these women will have normal foetuses. Fetal ultrasonography should be performed to detect multiple gestation, fetal demise, or fetal anomalies (neural tube defects, ventral abdominal wall defects, and urinary tract anomalies) as well as to confirm gestational age, as all of these factors are associated with elevated AFP levels. Amniocentesis is offered if the ultrasonography does not indicate the reason for the elevated AFP. Chorionic villus sampling is offered in the evaluation of suspected chromosomal anomalies as an adjunct to amniocentesis. Serum hCG would be indicated in the workup of suspected Down syndrome, where the AFP would be low, not elevate- The hCG level would be expected to be over 2-5 multiples of the mean (MoM) with Down syndrome.

      Your Answer: Cervical/vaginal trauma

      Explanation:

      A well contracted uterus excludes an atonic uterus. Delivery of large baby by a primigravida can cause cervical +/- vaginal tears which can lead to PPH.

      Your Answer: Immediate evacuation should be done once the diagnosis is made

      Explanation:

      Expectant management has been reported with unpredictable success rate ranging from 25–76%. Waiting for spontaneous expulsion of the products of conception would waste much time, during which women may suffer uncertainty and anxiety. However, when additional surgical evacuation is needed owing to failure, they may suffer from an emotional breakdown. It is thus not recommended for missed early miscarriage due to the risks of emergency surgical treatment and blood transfusion.

    • A 19-year-old primigravid woman, 34 weeks of gestation, came in for a routine blood test. Her platelet count is noted at 75x109/L (normal range is 150-400) . Which of the following can best explain the thrombocytopenia of this patient?

      Your Answer: Incidental thrombocytopaenia of pregnancy.

      Explanation:

      Incidental thrombocytopenia of pregnancy is the most common cause of thrombocytopenia in an otherwise uncomplicated pregnancy. The platelet count finding in this case is of little concern unless it falls below 50×109/L.

      Immune thrombocytopenia is a less common cause of thrombocytopenia in pregnancy. The anti-platelet antibodies cam cross the placenta and pose a problem both to the mother and the foetus. Profound thrombocytopenia in the baby is a common finding of this condition.

      Thrombocytopenia can occur in patients with severe pre-eclampsia. However, it is usually seen concurrent with other signs of severe disease.

      Maternal antibodies that target the baby’s platelets can rarely cause thrombocytopenia in the mother. Instead, it can lead to severe coagulation and bleeding complications in the baby as a result of profound thrombocytopenia.

      Systemic lupus erythematosus is unlikely to explain the thrombocytopenia in this patient.

    • A woman who underwent a lower (uterine) segment Caesarean section (LSCS) is informed that her placenta was retained and needed to be removed manually during the procedure. She is now experiencing intermittent vaginal bleeding with an oxygen saturation of 98%, a pulse of 84 bpm and a BP of 124/82mmHg. Her temperature is 37.8C. Which complication of C-section is the woman suffering from?

      Your Answer: Endometritis

      Explanation:

      Endometritis is inflammation of the inner lining of the uterus (endometrium). Symptoms may include fever, lower abdominal pain, and abnormal vaginal bleeding or discharge. It is the most common cause of infection after childbirth. The intermittent vaginal bleeding and the requirement for manual removal of the placenta suggest endometritis as the most possible diagnosis.

    • A 24-year-old Aboriginal woman at 10 weeks of gestation presents with a 2-week history of nausea and vomiting along with dizziness. She has not seen any doctor during this period.

      On examination, she is found to be dehydrated and her blood pressure is 95/60 mmHg with a drop in systolic blood pressure by more than 20% when she stands. She is unable to tolerate oral intake and her laboratory results show ketonuria.

      Which one of the following would be the best next step in management of this patient?

      Your Answer: Give metoclopramide and intravenous normal saline

      Explanation:

      Clinical picture mentioned is indicative of hyperemesis gravidarum with resultant hypovolemia and pre-shock state, were patient needs urgent fluid resuscitation and intravenous antiemetic medications. The first-line fluid for resuscitation is normal saline (0.9% NaCl) and metoclopramide an antiemetic drug which is safe for use in pregnancy (category A).

      Dextrose should be avoided in this situation as the sugar in the solution will leave behind a hypotonic fluid leading to severe hyponatraemic state which increases the risk for encephalopathy due to edema.

      Ondansetron is considered as the second-line of antiemetic drug under category B1 which is used in situations like more refractory vomiting, when patient is not responding to metoclopramide and in cases of recurrent hospital admissions due to hyperemesis gravidarum.

      Steroids such as prednisolone are considered as the third-line medication mostly used in resistant cases of hyperemesis gravidarum and should be used only after consulting an expert in the field.

    Correct

    • A 32-year-old lady is two weeks postpartum and in good health. She has painful defecation that is accompanied by some new blood on the toilet paper. Which of the following diagnoses is the most likely?

      Your Answer: Acute anal fissure.

      Explanation:

      The history of acutely painful defecation associated with spotting of bright blood is very suggestive of an acute anal fissure. Typically, the patient reports severe pain during a bowel movement, with the pain lasting several minutes to hours afterward. The pain recurs with every bowel movement, and the patient commonly becomes afraid or unwilling to have a bowel movement, leading to a cycle of worsening constipation, harder stools, and more anal pain. Approximately 70% of patients note bright-red blood on the toilet paper or stool. Occasionally, a few drops may fall in the toilet bowl, but significant bleeding does not usually occur with an anal fissure.. After gently spreading the buttocks, a close check of the anal verge can typically confirm the diagnosis.
      Rectal inspection is excruciatingly painful and opposed by sphincter spasm; however, if the fissure can be seen, it is not necessary to make the diagnosis at first.

      A perianal abscess, which presents as a sore indurated area lateral to the anus, or local trauma linked with anal intercourse or a foreign body, are two more painful anorectal disorders to rule out.

      Anal fistulae do not appear in this way, but rather with perianal discharge, and the diagnosis is based on determining the external orifice of the fistula.

      Although first-degree haemorrhoids bleed, they do not cause defecation to be unpleasant.

      Although carcinoma of the anus or rectum can cause painful defecation, it would be exceptional in this situation.

      Which of the following is considered an indicator of a more serious diagnosis of hyperemesis gravidarum?

      Your Answer: Hypokalaemia

      Explanation:

      In severe cases of hyperemesis, complications include vitamin deficiency, dehydration, and malnutrition, if not treated appropriately. Wernicke encephalopathy, caused by vitamin-B1 deficiency, can lead to death and permanent disability if left untreated. Additionally, there have been case reports of injuries secondary to forceful and frequent vomiting, including oesophageal rupture and pneumothorax.

      Electrolyte abnormalities such as hypokalaemia can also cause significant morbidity and mortality. Additionally, patients with hyperemesis may have higher rates of depression and anxiety during pregnancy.

It was also noted that she smokes 10 cigarettes and drinks 2 standard alcoholic drinks every day. She was tested for beta-hCG but it was not detectable.

      Which of the following is considered the most appropriate next step to establish a diagnosis?

      Your Answer: Transvaginal ultrasound

      Explanation:

      Asherman syndrome (intrauterine adhesions or intrauterine synechiae) occurs when scar tissue forms inside the uterus and/or the cervix. These adhesions occur after surgery of the uterus or after a dilatation and curettage.

      Patients with Asherman syndrome may have light or absent menstrual periods (amenorrhea). Some have normal periods based on the surface area of the cavity that is affected. Others have no periods but have severe dysmenorrhea (pain with menstruation).

      Although two-dimensional sonography may suggest adhesive disease, Asherman syndrome is more often evaluated initially with saline sonography or hysterosalpingography to demonstrate the adhesions.

    • A 25-year-old pregnant woman presented to your clinic complaining of urinary symptoms at 19 weeks of gestation.
      She is allergic to penicillin, with non-anaphylactic presentation.

      Urine microscopy confirmed the diagnosis of urinary tract infection and culture result is pending.

      From the options below, which is the most appropriate treatment for this patient?

      Your Answer: Cephalexin

      Explanation:

      According to the laboratory reports, patient has developed urinary tract infection and should be treated with one week course of oral antibiotics.
      As the patient is pregnant, antibiotics like cephalexin, co-amoxiclav and nitrofurantoin must be considered as these are safe during pregnancy.

      Due to this Patient’s allergic history to penicillin, cephalexin can be considered as the best option. Risk of cross allergy would have been higher if the patient had any history of anaphylactic reactions to penicillin.

      In Australia, Amoxicillin is not recommended to treat UTI due to resistance.Tetracyclines also should be avoided during pregnancy due to its teratogenic property.

      Transvaginal ultrasound shows cervical shortening to 2 cm, cervical dilation, and protrusion of fetal membranes into the cervical canal. Findings confirms the woman has developed non-specific symptoms of cervical insufficiency which may lead to premature delivery.

      Which among the following is the most appropriate management in this case?

      Your Answer: Reinforcement of the cervical ring with nonabsorbable suture material

      Explanation:

      Patient mentioned in the given case has developed clinical features of cervical insufficiency and the possible treatment options include:
      1- Cerclage, which is the technique used for the reinforcement of cervical ring with nonabsorbable suture material and is indicated based on ultrasonographic findings. It is the treatment of choice when cervical shortening is detected by ultrasonography before 22 to 24 weeks of gestation.

      2- Vaginal progesterone is used to reduce the risk of preterm delivery in women who have a prior history of idiopathic preterm delivery or cervical shortening, which is confirmed in the current pregnancy also by ultrasonography.This method is applicable only to those women who do not meet the criteria for Cerclage.

      All the other options of management are incorrect in the given case.

      Which of the following is the most appropriate advice to give to the patient given her situation?

      Your Answer: Caesarean section

      Explanation:

      Pulmonary hypertension (PH) is an increase of blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, leading to shortness of breath, dizziness, fainting, and other symptoms, all of which are exacerbated by exertion. PH in pregnancy carries a 25–56% maternal mortality rate with a mixture of intrapartum and postpartum deaths.

      Current recommendations for management of PH in pregnancy include termination of pregnancy if diagnosed early, or utilizing a controlled interventional approach with early nebulized prostanoid therapy and early elective caesarean section under regional anaesthesia. Other recommended therapies for peripartum management of PH include sildenafil and nitric oxide.

    • A 33-year-old woman is under your care during her pregnancy.

      She has had only one previous pregnancy in which her foetus had spina bifida.

      Identify the most appropriate assessment, from the following choices, that would aid in detection of spina bifida in her current pregnancy.

      Your Answer: Ultrasound of the fetal spine at 16-18 weeks of gestation.

      Explanation:

      An ultrasound of the foetal spine at 16-18 weeks of gestation is the most appropriate assessment (correct answer).

      Ultrasound performed at 11-12 weeks of gestation can diagnose anencephaly, another neural tube defect, however; any vertebral column defect is unlikely to be detected.

      In most cases of neural tube defects in the foetus, elevations will be noted in maternal alpha-fetoprotein levels at 12 to 15 weeks. However, it may not be possible to detect all such abnormalities and a confirmed diagnosis cannot be made.

      Additionally, elevations in alpha-fetoprotein levels do not always correlate to the presence of foetal neural tube defects.

      Nuchal translucency scans do not detect neural tube defects. They are performed to identify the risk of chromosomal abnormalities in the foetus.

      Explanation:

      Second-trimester ultrasound markers have low sensitivity and specificity for detecting Down syndrome, especially in a low-risk population.

      The highest detection rate is acquired with ultrasound markers combined with gross anomalies. Although the detection rate with this combination of markers is high in a high-risk population (50 to 75 percent), false-positive rates are also high (22 percent for a 100 percent Down syndrome detection rate).

      Vaginal examination was performed and revealed cord prolapse that is still pulsating.

      Which of the following is considered the most appropriate next step in managing the patient?

      Your Answer: Arrange for emergency caesarean delivery

      Explanation:

      Umbilical cord prolapse (UCP) occurs when the umbilical cord exits the cervical opening before the fetal presenting part. It is a rare obstetric emergency that carries a high rate of potential fetal morbidity and mortality. Resultant compression of the cord by the descending foetus during delivery leads to fetal hypoxia and bradycardia, which can result in fetal death or permanent disability.

      Certain features of pregnancy increase the risk for the development of umbilical cord prolapse by preventing appropriate engagement of the presenting part with the pelvis. These include fetal malpresentation, multiple gestations, polyhydramnios, preterm rupture of membranes, intrauterine growth restriction, preterm delivery, and fetal and cord abnormalities.

      The occurrence of fetal bradycardia in the setting of ruptured membranes should prompt immediate evaluation for potential cord prolapse.

      In overt prolapse, the cord is palpable as a pulsating structure in the vaginal vault. In occult prolapse, the cord is not visible or palpable ahead of the fetal presenting part. The definitive management of umbilical cord prolapse is expedient delivery; this is usually by caesarean section.

    • A 30-year-old woman is already in her second pregnancy and is 22 weeks pregnant. She presented to the medical clinic for evaluation of a vulval ulcer. A swab was taken and revealed a diagnosis of herpes simplex type II (HSV-2) infection. She was surprised about this diagnosis since neither she nor her husband has ever had this infection before. She insisted on knowing the source of the infection and was very concerned about her baby’s well-being and she asked how her condition may affect the baby.

      Which of the following statements is considered true regarding her situation?

      Your Answer: The primary infection is commonly asymptomatic

      Explanation:

      Genital herpes can be asymptomatic or have mild symptoms that go unrecognized. When symptoms occur, genital herpes is characterised by one or more genital or anal blisters or ulcers. Additionally, symptoms of a new infection often include fever, body aches and swollen lymph nodes.

      HSV-2 is mainly transmitted during sex through contact with genital or anal surfaces, skin, sores or fluids of someone infected with the virus. HSV-2 can be transmitted even if the skin looks normal and is often transmitted in the absence of symptoms.

      In rare circumstances, herpes (HSV-1 and HSV-2) can be transmitted from mother to child during delivery, causing neonatal herpes. Neonatal herpes can occur when an infant is exposed to HSV during delivery. Neonatal herpes is rare, occurring in an estimated 10 out of every 100 000 births globally. However, it is a serious condition that can lead to lasting neurologic disability or death. The risk for neonatal herpes is greatest when a mother acquires HSV for the first time in late pregnancy.

      In FAS, the most common orofacial changes are small eyelid fissures , flat facies, maxillary hypoplasia, short nose, long and hypoplastic nasal filter, and thin upper lip. The unique facial appearance of FAS patients is the result of changes in 4 areas: short palpebral fissures, flat nasal bridge with an upturned nasal tip, hypoplastic philtrum with a thin upper vermillion border, and a flat midface. Other facial anomalies include micrognathia, occasional cleft lip and/or palate and small teeth with defective enamel.

    • Etiological factors in spontaneous abortion include:

      Your Answer: All of the options given

      Explanation:

      Spontaneous abortion is the loss of pregnancy naturally before twenty weeks of gestation. Colloquially, spontaneous abortion is referred to as a ‘miscarriage’ to avoid association with induced abortion. Early pregnancy loss refers only to spontaneous abortion in the first trimester. In 50% of cases, early pregnancy loss is believed to be due to fetal chromosomal abnormalities. Advanced maternal age and previous early pregnancy loss are the most common risk factors. For example, the incidence of early pregnancy loss in women 20-30 years of age is only 9 to 17%, while the incidence at 45 years of maternal age is 80%. Other risk factors include alcohol consumption, smoking, and cocaine use.

      Several chronic diseases can precipitate spontaneous abortion, including diabetes, celiac disease, and autoimmune conditions, particularly anti-phospholipid antibody syndrome. Rapid conception after delivery and infections, such as cervicitis, vaginitis, HIV infection, syphilis, and malaria, are also common risk factors. Another important risk factor is exposure to environmental contaminants, including arsenic, lead, and organic solvents. Finally, structural uterine abnormalities, such as congenital anomalies, leiomyoma, and intrauterine adhesions, have been shown to increase the risk of spontaneous abortion.

The foetus lies transverse till 26-28th week of gestation, after which it usually changes its position from transverse to a longitudinal lie with head down. A transverse lie can occur in conditions like grand multiparity, preterm foetus, placenta previa and pelvic contraction.

    Correct

    • A 33-year-old 'grand multiparous' woman, who has previously delivered seven children by normal vaginal delivery, spontaneously delivers a live baby weighing 4750gm one hour ago after a three-hour long labour period. Shortly after, an uncomplicated third stage of labour, she goes into shock (pulse 140/min, BP 80/50 mmHg). At the time of delivery, total blood loss was noted at 500mL, and has not been excessive since then. What is the most probable diagnosis of this patient?

      Your Answer: Uterine rupture.

      Explanation:

      The patient most likely suffered a uterine rupture. It occurs most often in multiparous women and is less often associated with external haemorrhage. Shock develops shortly after rupture due to the extent of concealed bleeding.

      Uterine inversion rarely occurs when after a spontaneous and normal third stage of labour. Although it can lead to shock, it is usually associated with a history of controlled cord traction or Dublin method of placenta delivery before the uterus has contracted. This diagnosis is also strongly considered when shock is out of proportion to the amount of blood loss.

      An overwhelming infection is unlikely in this case when labour occurred for a short period of time. Uterine atony and amniotic fluid embolism are more associated with excessive vaginal bleeding, which is not evident in this case.

      On examination, she presents with signs of moderate degree of dehydration, along with a weight loss of approximately 10%.
      Urine dipstick examination is negative for both leukocytes and nitrites but is positive for ketones. Serum ketone level is elevated and other electrolytes including blood glucose levels are within normal range.

      Which of the below mentioned treatment options is not appropriate in this situation?

      Your Answer: Encourage oral intake and discharge home

      Explanation:

      Patient mentioned in the case has developed severe nausea and vomiting at the initial weeks of pregnancy. If the following clinical features are present, it confirms the diagnosis of hyperemesis gravidarum:
      – Weight loss of more than 5% of pre-pregnancy weight
      – Moderate to severe dehydration.
      – Ketosis
      – Electrolyte abnormalities.

      Management of hyperemesis gravidarum include:
      – Temporary suspension of oral intake, followed by gradual resumption.
      – Intravenous fluid resuscitation, beginning with 2 L of Ringer’s lactate infused over 3 hours to maintain a urine output of more than 100 mL/h.
      – Use of Antiemetics like metoclopramide, if needed.
      – Oral administration of Vitamin B6.
      – Replacement of electrolytes if required in the case.

      Encouraging oral intake and sending this patient home without any intravenous hydration, is not considered the correct treatment option in this case.

      Your Answer: A previous infant with Group B streptococcus disease regardless of present culture

      Explanation:

      Group B Streptococcus (GBS) or Streptococcus agalactiae is a Gram-positive bacteria which colonizes the gastrointestinal and genitourinary tract. In the United States of America, GBS is known to be the most common infectious cause of morbidity and mortality in neonates. GBS is known to cause both early onset and late onset infections in neonates, but current interventions are only effective in the prevention of early-onset disease.

      The main risk factor for early-onset GBS infection is colonization of the maternal genital tract with Group B Streptococcus during labour. GBS is a normal flora of the gastrointestinal (GI) tract, which is thought to be the main source for maternal colonization.

      The principal route of neonatal early onset GBS infection is vertical transmission from colonized mothers during passage through the vagina during labour and delivery.

      Intravenous penicillin G is the treatment of choice for intrapartum antibiotic prophylaxis against Group B Streptococcus.

      Clinical conditions associated with breech presentation include those that may increase or decrease fetal motility, or affect the vertical polarity of the uterine cavity. Prematurity, multiple gestations, aneuploidies, congenital anomalies, Mullerian anomalies, uterine leiomyoma, and placental polarity as in placenta previa are most commonly associated with a breech presentation. Also, a previous history of breech presentation at term increases the risk of repeat breech presentation at term in subsequent pregnancies.

      Conditions that change the vertical polarity or the uterine cavity, or affect the ease or ability of the foetus to turn into the vertex presentation in the third trimester include:
      – Mullerian anomalies
      – Placentation
      – Uterine leiomyoma
      – Prematurity
      – Aneuploidies and fetal neuromuscular disorders
      – Congenital anomalies
      – Polyhydramnios and oligohydramnios
      – Laxity of the maternal abdominal wall.

    Correct

    • An 18-year-old pregnant woman presents to the clinic for a routine check-up. She is at the 5th week of gestation. Except for morning nausea, she denies any problems with her pregnancy so far. The patient is allergic to penicillin. Physical exam is unremarkable and appropriate for gestational age. Routine screening lab tests were ordered. VDRL screening returned positive and was confirmed by the FTA-ABS test.

      Which of the following is considered the best management of this patient?

      Your Answer: Penicillin allergy skin testing and penicillin desensitization, if necessary

      Explanation:

      Penicillin is the treatment of choice for treating syphilis. For treatment of syphilis during pregnancy, no proven alternatives to penicillin exist. Treatment guidelines recommend desensitization in penicillin-allergic pregnant women, followed by treatment with penicillin. Syphilis in pregnancy is associated with mental retardation, stillbirth and sudden infant death syndrome; therefore it should be treated promptly.

      – Data are insufficient to recommend ceftriaxone for treatment of maternal infection and prevention of congenital syphilis.
      – Erythromycin and azithromycin should not be used, because neither reliably cures maternal infection or treats an infected foetus.
      – Tetracycline and doxycycline are contraindicated in pregnancy and ceftriaxone is much less effective than penicillin.

    Correct

    • A 33-year-old nulliparous pregnant female at the 21st week of pregnancy came to the gynaecological clinic for evaluation of vulval ulcer. A swab was taken revealing the herpes simplex type 2 virus. There is no prior history of such lesions and her partners of the last decade had no history of the infection. She's anxious about how she got the condition and the potential consequences for her and her unborn kid. Which of the following suggestions is the most appropriate?

      Your Answer: The primary infection is commonly asymptomatic.

      Explanation:

      Despite the fact that this question includes many true-false options, the knowledge examined is particularly essential in the treatment of women who have genital herpes.
      It answers many of the questions that such women have regarding the disease, how it spreads, how it may be controlled, and how it affects an unborn or recently born child.
      All of these issues must be addressed in a counselling question.
      Currently, the most prevalent type of genital herpes is type 1, while in the past, type 2 was more common, as confirmed by serology testing.
      Type 2 illness is nearly always contracted through sexual contact, but it can go undetected for years.
      Acyclovir can be taken during pregnancy, and there are particular reasons for its usage.
      Neonatal herpes is most usually diagnosed when the newborn has no cutaneous lesions, and past genital herpes in the mother is protective against neonatal infection, although not always.
      Where the genital infection is the initial sign of the disease rather than a relapse of earlier disease, neonatal herpes is far more frequent.
      Many patients and doctors are unaware that, while the original infection might be deadly, it is usually asymptomatic.
      This explains how the illness spreads between sexual partners when neither has had any previous symptoms of the disease.

    • A 29-year-old woman presented to the emergency department with severe nausea and vomiting at 8 weeks of being pregnant. She is unable to take solid food but is capable of drinking small sips of liquids. She is concerned that she might have gastroenteritis because her partner was noted to have recently been diagnosed with it.

      Which of the following is considered the next best step to investigate given the situation?

      Your Answer: Pelvic ultrasound

      Explanation:

      Hyperemesis gravidarum refers to intractable vomiting during pregnancy, leading to weight loss and volume depletion, resulting in ketonuria and/or ketonemia.

      The exact cause of hyperemesis gravidarum remains unclear. However, there are several theories for what may contribute to the development of this disease process such as:
      1. Hormone changes – hCG levels peak during the first trimester, corresponding to the typical onset of hyperemesis symptoms. Estrogen is also thought to contribute to nausea and vomiting in pregnancy.
      2. Changes in the Gastrointestinal System – the lower oesophageal sphincter relaxes during pregnancy due to the elevations in estrogen and progesterone. This leads to an increased incidence of gastroesophageal reflux disease (GERD) symptoms in pregnancy, and one symptom of GERD is nausea.
      3. Genetics – an increased risk of hyperemesis gravidarum has been demonstrated among women with family members who also experienced hyperemesis gravidarum.

      The average onset of symptoms happens approximately 5 to 6 weeks into gestation. The physical exam should include fetal heart rate (depending on gestational age) and an examination of fluid status, including an examination of blood pressure, heart rate, mucous membrane dryness, capillary refill, and skin turgor. A patient weight should be obtained for comparison to previous and future weights. If indicated, abdominal examination and pelvic examination should occur to determine the presence or absence of tenderness to palpation.

    Correct

    • The performance of a cervical cerclage at 14 weeks of gestation is determined by which of the following indications?

      Your Answer: 2 or more consecutive prior second trimester pregnancy losses

      Explanation:

      Cervical cerclage is performed as an attempt to prolong pregnancy in certain women who are at higher risk of preterm delivery.

      There are three well-accepted indications for cervical cerclage placement. According to the American College of Obstetricians and Gynaecologists (ACOG), a history-indicated or prophylactic cerclage may be placed when there is a “history of one or more second-trimester pregnancy losses related to painless cervical dilation and in the absence of labour or abruptio placentae,” or if the woman had a prior cerclage placed due to cervical insufficiency in the second trimester.

      An ultrasound-indicated cerclage may be considered for women who have a history of spontaneous loss or preterm birth at less than 34 weeks gestation if the cervical length in a current singleton pregnancy is noted to be less than 25 mm before 24 weeks of gestation. It is important to note that this recommendation is invalidated without the history of preterm birth.

      Physical examination-indicated cerclage (also known as emergency or rescue cerclage) should be considered for patients with a singleton pregnancy at less than 24 weeks gestation with advanced cervical dilation in the absence of contractions, intraamniotic infection or placental abruption.

    • A 22-year-old female in her 18th week of pregnancy presented with right iliac fossa pain while getting up from a chair and has been coughing and sneezing.

      On examination, there is no palpable mass or rebound tenderness.

      What will be the most likely cause for patient's complaint?

      Your Answer: Round ligament strain

      Explanation:

      Patient’s symptoms and signs are suggestive of round ligament strain, which is a normal finding during pregnancy, especially in the 2nd trimester, and it does not require any medical intervention.

      Round ligament is a rope-like fibromuscular band which extends from the anterolateral aspect of uterus anteriorly between the layers of the broad ligament, and passing through the deep inguinal ring into the inguinal canal.
      A sharp, sudden spasm in the right iliac fossa which lasts for a few seconds which is usually triggered by sneezing, coughing, laughing and rolling over in bed are the common presentations of a round ligament pain.

      Ectopic pregnancy and rupture of ectopic pregnancy are two unlikely diagnosis in this patient as she is in the second trimester of her pregnancy, whereas both the mentioned conditions occur during the first trimester.

      Although appendicitis presents with pain in right iliac fossa, the pain is not causes by coughing or sneezing. Also, there will be other symptoms like tenderness and rebound tenderness in right iliac fossa in case of appendicitis.

    • A 35-year-old woman presented to the emergency department with complaints of abdominal pain and nausea. She noted that her symptoms began 2 days ago but has severely increased over the last 3 hours. It was also noted that the patient has passed several vaginal blood clots in the last hour.
      Upon history taking, it was noted that she has a history of irregular menstrual cycles and is not sure of the date of her last period. Two years ago, she was diagnosed with a bicornuate uterus during an infertility evaluation. Aside from these, the patient has no other medical conditions and has no past surgeries.

      Further examination was done and the following are her results:
      BMI is 28 kg/m2
      Blood pressure is 90/56mmHg
      Pulse is 120/min

      An abdominal examination was performed and revealed guarding with decreased bowel sounds. Speculum examination also revealed moderate bleeding with clots from the cervix. Her urine pregnancy test result turned out positive. A transvaginal ultrasound was performed and revealed a gestational sac at the upper left uterine cornu and free fluid in the posterior cul-de-sac of the pelvis.

      Which of the following is considered the next step in best managing the patient's condition?

      Your Answer: Surgical exploration

      Explanation:

      Ectopic pregnancy is a known complication of pregnancy that can carry a high rate of morbidity and mortality when not recognized and treated promptly. It is essential that providers maintain a high index of suspicion for an ectopic in their pregnant patients as they may present with pain, vaginal bleeding, or more vague complaints such as nausea and vomiting. Ectopic pregnancy, in essence, is the implantation of an embryo outside of the uterine cavity most commonly in the fallopian tube.

      Providers should identify any known risk factors for ectopic pregnancy in their patient’s history, such as if a patient has had a prior confirmed ectopic pregnancy, known fallopian tube damage (history of pelvic inflammatory disease, tubal surgery, known obstruction), or achieved pregnancy through infertility treatment.

      Performance of laparoscopic surgery is safe and effective treatment modalities in hemodynamically stable women with a non-ruptured ectopic pregnancy.

      Patients with relatively low hCG levels would benefit from the single-dose methotrexate protocol. Patients with higher hCG levels may necessitate two-dose regimens. There is literature suggestive that methotrexate treatment does not have adverse effects on ovarian reserve or fertility. hCG levels should be trended until a non-pregnancy level exists post-methotrexate administration.

      Surgical management is necessary when the patients demonstrate any of the following: an indication of intraperitoneal bleeding, symptoms suggestive of ongoing ruptured ectopic mass, or hemodynamically instability. Women who present early in pregnancy and have testing suggestive of an ectopic pregnancy would jeopardize the viability of an intrauterine pregnancy if given Methotrexate. The patient may have a cervical ectopic pregnancy and would thus run the risk of haemorrhage and potential hemodynamic instability if a dilation and curettage are performed.

      Your Answer: Chorionic Villi Sampling (CVS)

      Explanation:

      CVS has decreased in frequency with the recent increased uptake of cell-free DNA screening. It remains the only diagnostic test available in the first trimester and allows for diagnostic analyses, including fluorescence in situ hybridization (FISH), karyotype, microarray, molecular testing, and gene sequencing. CVS is performed between 10 and 14 weeks’ gestation. CVS has been performed before 9 weeks in the past, though this has shown to increase the risk of limb deformities and, therefore, is no longer recommended.

    • A 22-year-old nulliparous otherwise healthy woman presents with lower abdominal pain at 16 weeks of gestation. Her body temperature is 37.8 degrees Celsius. She appears to be in good health and is eating properly. Her uterus had been discovered to be retroverted but of normal size at her prior antenatal check at 11 weeks of pregnancy. Which of the following diagnoses is the most likely?

      Your Answer: Urinary tract infection.

      Explanation:

      Lower abdominal pain can be caused by any of the conditions listed in the answers.
      A urinary tract infection is the most likely cause.
      Unless it was an abdominal ectopic or an interstitial pregnancy, an ectopic pregnancy.
      will almost definitely have shown up before the 15th week of pregnancy.
      A retroverted gravid uterus may impinge at 15 weeks of pregnancy, however, this is unlikely to be linked to a temperature of 37.8°C.
      It’s also possible that it’s the source of acute urine retention.
      Complications of the corpus luteum cyst normally manifest themselves considerably earlier in pregnancy, and severe appendicitis is far less likely to be the source of discomfort than a urinary tract infection.

    • A 22-year-old woman, G1P0, comes to your clinic at the 12th week of her pregnancy, complaining of a mild vaginal bleeding since last 12 hours along with mild but periodic pain.

      On vaginal examination, cervical os is found to be closed with mild discharge which contains blood clots. Ultrasound performed confirms the presence of a live fetus with normal foetal heart sound.

      What among the following will be the most likely diagnosis?

      Your Answer: Threatened miscarriage

      Explanation:

      The case is most likely diagnosed a threatened miscarriage.
      A diagnosis of threatened miscarriage is made when there is uterine bleeding in the presence of a closed cervix and is confirmed by the sonographic visualisation of an intrauterine pregnancy with detectable fetal cardiac activity. Miscarriages may not always follow even though there was multiple episodes or large amounts of bleeding, therefore the term “threatened” is used in these cases.
      At 7 to 11 weeks of gestation, about 90 to 96 percent cases of pregnancies, will not usually miscarry if they have presented with an intact fetal cardiac activity along with vaginal bleeding and if bleeding occurs at the later weeks of gestational age chances of success rate is higher.

      Topic review:
      – Inevitable miscarriages presents with a dilated cervix, increasing uterine bleeding and painful uterine contractions. The gestational tissues can often be felt or seen through the cervical os and its passage occurs within a short time.
      – In Incomplete miscarriage, the membranes will rupture passing the fetus out, but significant amounts of placental tissue will be retained. This occurs most commonly in late first trimester or early second trimester. On examination, the cervical os will be opened and the gestational tissue can be observed in the cervix, with a uterine size smaller than expected for gestational age, but not well contracted. The amount of bleeding varies but can be severe enough to cause hypovolemic shock. There will be painful cramps
      ontractions and ultrasound reveals tissue in the uterus.
      – A missed miscarriage refers to the in-utero death of the embryo or fetus prior to 20th week of gestation, with retention of the pregnancy for a prolonged period of time. In this case, women may notice that symptoms associated with early pregnancy like nausea, breast tenderness, etc have abated and they don’t “feel pregnant” anymore.
      Vaginal bleeding may occur but the cervix usually remains closed. Ultrasound reveals an intrauterine gestational sac with or without an embryonic/fetal pole, but no embryonic/fetal cardiac activity will be noticed.
      – Complete miscarriage, usually occurs before 12 weeks of gestation and the entire contents of the uterus will be expelled resulting in a complete miscarriage. In this case, physical examination reveals a small, well contracted uterus with an open or closed cervix with scanty vaginal bleeding and mild cramping. Ultrasound will reveal an empty uterus with no extra-uterine gestation.

      Explanation:

      No adverse reactions in breastfed infants have been reported from maternal warfarin use during lactation, even with a dose of 25 mg daily for 7 days. There is a consensus that maternal warfarin therapy during breastfeeding poses little risk to the breastfed infant.

During vaginal delivery, she sustained small vaginal laceration, suture repair was not done as the lesion were small. Presently she is breastfeeding her baby.

      Physical examination shows no uterine tenderness and the rest of the examinations were unremarkable.

      Which of the following can be the most likely cause of this Patient's fever?

      Your Answer: Infection of the unrepaired vaginal laceration

      Explanation:

      As the time of onset of fever is the 4th day of postpartum and absence of uterine tenderness on exam makes infection of vaginal laceration the most likely cause of this presentation.

      Exquisite uterine tenderness will be experienced in case of endometritis and symptoms are expected to start much earlier like by 2-3 days of postpartum.

      UTI is often expected on days one or two of postpartum, also there are no urinary symptoms suggestive of UTI

      Breast engorgement usually develops by 7th -2st day of postpartum and in the given case it’s too soon for it to occur.

      As it is expected during the first 2 hours postpartum, Atelectasis is unlikely to be the cause of symptoms in the given case.

On the fifth day of postpartum patient presents with heavy bright red vaginal bleeding and mentions that lochia was in scant amounts compared to her previous pregnancy.

      On examination, her temperature was 38.8°C and uterus is mildly tender to palpation.

      Which one of the following would most likely be her diagnosis?

      Your Answer: Retained products of conception

      Explanation:

      Secondary postpartum hemorrhage of bright red character accompanied with fever, between 24 hours to 12 weeks of postpartum is suggestive of retained products of conception (RPOC).
      The basal portion of the decidua may remain after separation of placenta in many cases. This decidua will then divides into two layers, the superficial layer which will be shed spontaneously and the deep layer which will regenerates and covers the entire endometrial cavity with in 16 days of postpartum.
      Normal shedding of blood and decidua is referred to as lochia rubra, which is red / reddish brown in colour and it lasts for few days following delivery. This vaginal discharge gradually becomes watery and pinkish brown in colour, lasting for 2 to 3 weeks and is called as lochia serosa. Ultimately, this discharge becomes yellowish-white called as lochia alba.

      Scanty lochia in the first few days after delivery is suggestive of the placental site not undergoing involution, which occurs mostly due to RPOC. Later these retained products will undergo necrosis resulting in fibrin deposition which will eventually form a placental polyp. Detachment of this scar of polyp will result in brisk hemorrhage and the remaining necrotic products will get infected resulting in uterine infection which will present with fever, lower abdominal pain and uterine tenderness.

      Endometritis can lead to fever, offensive lochia and abdominal pain with tenderness. It is the most common cause of postpartum fever, but occurs within the first 5 days of postpartum with the peak incidence between days 2 and 3. Though vaginal bleeding is a presenting feature, bright red bleeding is unlikely of endometritis.

      Another cause of postpartum fever is genital lacerations which have a peak incidence of wound infection between 4th and 5th days. Although fever as a temporal symptom favours wound infection, this diagnosis is less likely in the given case as wound infection will not affect the normal course of lochia, also it does not present as heavy bright red bleeding. Moreover, there are no symptoms like erythema, tenderness or discharge in history suggestive of wound infection.

      Another cause of bleeding and fever can be cervical tear but this tends to present as primary postpartum hemorrhage rather than secondary, which occurs after 24 hours of postpartum. An overlooked and infected minor cervical laceration can cause fever but ii will not result in bright red bleeding, also genital tract lacerations do not affect lochia.

      It is very unlikely for uterine rupture to occur 24 hours after delivery.

      Among the following results, which would indicate further assessment for trisomy 21?

      Your Answer: Decreased pregnancy-associated plasma protein (PAPP-A)

      Explanation:

      Decreased pregnancy-associated plasma protein (PAPP-A) in the first trimester of pregnancy is an indication to carry out further diagnostic testing for Down syndrome.

      Antenatal tests available for screening Down syndrome are divided into two types:
      – Screening tests includes maternal serum screening and ultrasound which are safe to conduct with relatively low predictive values.
      – Diagnostic tests like chorionic villous sampling and amniocentesis are confirmative but carries higher risk of miscarriage as 1 in 100 and 1 in 200 respectively.

      a) Serum screening tests for Down syndrome during first-trimester includes:
      1. Pregnancy-associated plasma protein (PAPP-A) will be decreased in case of Down syndrome.
      2. Free ß-human chorionic gonadotropin (HCG) will be increased in cases of Down syndrome.
      If these screening tests are combined with first-trimester ultrasound nuchal translucency, it is found to be more accurate than doing only one of these tests.

      b) Second-trimester serum screening tests for identifying Down syndrome:
      1.Alpha-fetoprotein will be decreased.
      2.Unconjugated oestriol will be decreased.
      3.Free ß-HCG will be increased
      4.Inhibin A will be increased.
      These tests combined with maternal age and ultrasound results will provide more accurate predictive values.

    • A 28-year-old primigravid woman at 18 weeks of gestation comes to office for a routine prenatal visit and anatomy ultrasound. Patient feels well generally and has no concerns, also has no chronic medical conditions, and her only daily medication is a prenatal vitamin. She is accompanied by her mother as her husband was unable to get off work. 

      Ultrasound shows a cephalic singleton fetus measuring at <10th percentile consistent with severe growth restriction. There are bilateral choroid plexus cysts, clenched fists, and a large ventricular septal defect.  Amniotic fluid level is normal with a posterior and fundal placenta. 

      Which of the following statements is the most appropriate initial response by the physician?

      Your Answer: There are some things about your ultrasound that I need to discuss with you; is it okay to do that now?

      Explanation:

      SPIKES protocol for delivering serious news to patients includes:
      – Set the stage includes arranging for a private, comfortable setting space, introduce patient/family & team members, maintain eye contact & sit at the same level and schedule appropriate time interval & minimize space for interruptions.
      – Perception: Use open-ended questions to assess the patient’s/family’s perception of the medical situation.
      – Invitation: should ask patient/family how much information they would like to know and remain cognizant of their cultural, educational & religious issues.
      – Knowledge:
      Warn the patient/family that serious news is coming, Speak in simple & straightforward terms, stop & check whether they are understanding.
      – Empathy: Express understanding & give support when responding to emotions
      – Summary & strategy: Summarize & create follow-through plan, including end-of-life discussions if applicable.

      The ultrasound findings of severe growth restriction, bilateral choroid plexus cysts, clenched fists, and a large ventricular septal defect are consistent with trisomy 18, the second most common autosomal trisomy, which results in fetal loss or neonatal death in the majority of cases.  In this case, the physician is to deliver a very serious news to the patient who is presenting for a routine visit, believing her pregnancy was normal.  When serious news is unexpected, it is especially important to prepare the patient and determine how the patient would like to receive the results.
      The physician is supposed to provide a comfortable setting and must ask patient’s permission to share the results. This allows the patient to respond with her preference and avoids making assumptions about whom, if anyone, she would like to be present with.  For example, some patients may prefer to defer discussion of the results until a major support person (eg, husband, mother) is present. In addition to establish patient’s preferred setting, physician should determine how much information the patient would like to receive. Some patients will prefer a detailed medical information about diagnosis and prognosis, whereas others may prefer to have time to process the news emotionally and receive further information later.  The SPIKES protocol (Setting the stage, Perception, Invitation, Knowledge, Empathy, and Summary/strategy) is a six-step model that can guide physicians in delivering serious news to patients.

      These statements do not allow the patient to choose how she receives the results and assume that she does not want her mother present.

      This statement fails to prepare the patient for serious news and prematurely jumps to sharing results using technical, medical terminology that may be difficult for the patient to comprehend. This approach could also be upsetting to a patient undergoing a routine ultrasound who is not expecting anything abnormal.

      This statement inappropriately determines when and with whom the patient should receive the results. Instead the patient should be asked how she prefers to receive the results.

      While delivering unexpected, serious news, physicians should prepare the patient and determine how the patient prefers to receive the information.

    • A 22-year-old pregnant woman attends clinic for a fetal scan at 31 weeks. She complains of difficulty breathing and a distended belly. U/S scan was done showing polyhydramnios and an absent gastric bubble. What is the most likely diagnosis?

      Your Answer: Oesophageal atresia

      Explanation:

      Oesophageal atresia of the foetus interrupts the normal circulation of the amniotic fluid. This causes polyhydramnios and subsequent distension of the uterus impacting proper expansion of the lungs. This would explain the difficulty breathing.

      Your Answer: DIC

      Explanation:

      Disseminated intravascular coagulation (DIC) in pregnancy is the most common cause of an abnormal haemorrhage tendency during pregnancy and the puerperium. Although pregnancy itself can cause DIC, its presence is invariably evidence of an underlying obstetric disorder such as abruptio placentae, eclampsia, retention of a dead foetus, amniotic fluid embolism, placental retention or bacterial sepsis.

    Incorrect

    • A 26-year-old female G2P1 is in labour at the 38th week of gestation. Her membranes ruptured about 8 hours ago. At the moment, she is having contractions lasting 60 seconds every 4 minutes and is 8 cm dilated. The fetal heart tone baseline is currently 80/min with absent variability. The pregnancy was uneventful and she had regular prenatal check-ups.
      Which of the following is the most appropriate next step in management?

      Your Answer: Immediate Caesarean section

      Correct Answer: Maternal position change and oxygen

      Explanation:

      This patient is towards the end of the first stage of labour and is having complications. Labour is divided into 3 stages. The first stage begins at regular uterine contractions and ends with complete cervical dilatation at 10 cm. It has a latent phase and an active phase- The active phase is usually considered to have begun when cervical dilatation reaches 4 cm. So this patient is in the active phase of the first stag- The second stage begins with complete cervical dilatation and ends with the delivery of the foetus. The third stage of labour is the period between the delivery of the foetus and the delivery of the placenta and fetal membranes.

      This patient’s contractions seem adequate and yet the fetal heart tone with baseline 80/min and absent variability suggests fetal distress. This is category III of the fetal heart rate pattern because the baseline rate is < 110/min with absent variability. It is usually predictive of abnormal acid-base status. The recommended actions are maternal position change and oxygen administration, discontinuation of labour stimulus such as oxytocin, treatment of possible underlying conditions, and expedited delivery.
      → Magnesium sulphate infusion is mainly used to prevent eclamptic seizures and despite no evidence of its effectiveness as a tocolytic agent, it is used sometimes to reduce risks of preterm birth.
      → Fetal scalp pH monitoring would help determine if there is indeed an acidosis and should be done before deciding whether a Caesarean section is necessary, but maternal position change and oxygen administration should be done first.
      → Ultrasonography may be used for preinduction cervical length measurement or if the active stage has already started- It is considered more accurate than digital pelvic exam in the assessment of fetal descent; however, at this point maternal position change and oxygen administration should be done first.
      → Immediate Caesarean section would be done if fetal scalp pH monitoring revealed a pH < 7.20. At this point, the best next step is maternal position change and oxygen administration.

    Correct

    • A 21-year-old primigravida female presents to the emergency department at 41 weeks gestation.

      She complains of a nine hour history of irregular painful contractions.

      On examination of her pelvis, her cervix is fully effaced, but only 2 - 3 cm dilated. The fetal head is at the level of the ischial spines in a left occipito-posterior (LOP) position. The membranes ruptured an hour ago.

      What would be the best next line of management?

      Your Answer: Oxytocic (Syntocinon4) infusion.

      Explanation:

      The best next line of management is to administer an oxytocic (Syntocinon) infusion.

      This is because the progress of labour is slow, and it necessary to augment it. As the membranes have already ruptured, the next step is to increase the contractions and induce labour using an infusion of oxytocic (Syntocinon) infusion.

      Extra fluid is also required, but this will be administered alongside the Syntocinon infusion.

      A lumbar epidural block is indicated in patients with an occipito-posterior (OP) position. This should not be attempted until more pain relief is required and the progress of labour is reassessed.

      A Caesarean section may be necessary due to obstructed labour or fetal distress, it is not indicated at this stage.

      Taking blood and holding it in case cross-matching is ultimately required is common, but most patients do not have blood cross-matched prophylactically in case there is a need to be delivered by Caesarean section and require a transfusion.

    Correct

    • A patient comes to your office with her last menstrual period 4 weeks ago. She thinks that she may be pregnant because she has not had her period yet, but denies any symptoms such as nausea, fatigue, urinary frequency, or breast tenderness.

      As she has a history of previous ectopic pregnancy, she is very anxious to find out and wants to be sure to get early prenatal care.

      Among the following actions which is most appropriate at this time?

      Your Answer: Order a serum quantitative pregnancy test.

      Explanation:

      Nausea, fatigue, breast tenderness, and increased frequency of urination are the most common symptoms of pregnancy, but their presence is not considered definitive as they are nonspecific symptoms which are not consistently found in early pregnancy, also these symptoms can occur even prior to menstruation.

      In pregnancy a physical examination will reveal an enlarged uterus which is more boggy and soft, but these findings are not apparent until after 6th week of gestation. In addition, other conditions like adenomyosis, fibroids, or previous pregnancies can also result in an enlarged uterus which is palpable on physical examination.

      An abdominal ultrasound will not demonstrate a gestational sac until a gestational age of 5 to 6 weeks, nor will it detect an ectopic pregnancy soon after a missed menstrual period, therefore it is not indicated in this patient.

      A Doppler instrument will detect fetal cardiac action usually after 10 weeks of gestation.

      A sensitive serum quantitative pregnancy test can detect placental HCG levels by 8 to 9 days post-ovulation and is considered as the most appropriate next step in evaluation of this patient.

    Correct

    • A 26-year -old woman, who underwent an episiotomy during labour, presented with severe vaginal pain 4 days after the procedure.

      At the site of the episiotomy, an 8-cm hematoma is noted on examination. Also the woman is found to be hemodynamically stable.

      Among the following, which is considered the most appropriate next step in management?

      Your Answer: Explore the hematoma

      Explanation:

      In most cases reported, puerperal hematomas arise due to bleeding lacerations related to operative deliveries or episiotomy, and in rare cases from spontaneous injury to a blood vessel in the absence of any laceration/incision of the surrounding tissue. Vulval, vaginal/paravaginal area and retroperitoneum are considered the most common locations for puerperal hematomas.

      Most puerperal hematomas are diagnosed based on the presence of characteristic symptoms and physical examination findings:
      VuIvar hematoma usually presents as a rapidly developing, severely painful, tense and compressible mass which is covered by skin of purplish discoloration. A vulvar hematoma can also be an extension of a vaginal hematoma which was dissected through a loose subcutaneous tissue into the vulva.
      Vaginal hematomas often present with rectal pressure, were hemodynamic instability caused due to bleeding into the ischiorectal fossa and paravaginal space are the first signs and can result in hypovolemic shock. In these cases a large mass protruding into the vagina is often found on physical examination.
      Retroperitoneal hematomas are asymptomatic initially and extend between the folds of broad ligament. Patients suffering will often present with tachycardia, hypotension or shock due to the significant accumulated of blood in the retroperitoneal space. Unless the hematoma is associated with trauma, patients will not present with pain, only signs will be a palpable abdominal mass or fever.

      Treatment of hematoma depends mostly on the size and location:
      Non-expanding hematomas which are <3cm in size can be managed conservatively with analgesics and application of ice packs. An expanding hematoma or those greater than 3cm is managed effectively with surgical exploration under anesthesia, were an incision is made to evacuate the hematoma. The surgical site should not be sutured and vagina is often packed for 12-24 hours, an indwelling urinary catheter also may be indicated. In the given case, patient presents with a large haematoma (>3cm) which needs surgical excision and evacuation.

      Aspiration of the hematoma is not an appropriate treatment. If surgical intervention is indicated excision and evacuation is the preferred option, followed by vaginal packing for 12-24 hours.

    • A 25-year old Asian woman comes to your clinic at 36 weeks of gestation. She was diagnosed with breech at 32 weeks. She is not in labor and a manual examination of the uterus is suggestive of breech position.

      Which one of the following would be the next best step in management of this patient?

      Your Answer: Pelvic ultrasound

      Explanation:

      An ultrasonography is performed for confirmation, as well as for the evaluation of maternal pelvis, fetal size and viability in cases were breech presentation is suspected on manual examination. As there is a chance for spontaneous correction of breech presentation into cephalic during 36 to 37 weeks, this should be considered in every future visit. The chances for spontaneous version reduces to 25% if breech position persists beyond this period of time.

      It an external cephalic version should be offered to all women with breech presentation, provided there are no contraindications or indication for cesarean delivery due to other reasons.

    • A 30-year-old woman, gravida 2 para 1, at 10 weeks of gestation comes to your office for an initial prenatal visit. Patient has had no vaginal bleeding or cramping and her first pregnancy was uncomplicated which ended with a spontaneous term vaginal delivery. She has no chronic medical conditions and has had no previous surgeries. Patient takes a daily dose of prenatal vitamin and does not use tobacco, alcohol, or any other illicit drugs. 

      On examination her blood pressure is 122/80 mm of Hg and pulse is 70/min and BMI is 24 kg/m2.  The uterine fundus is palpated above the pubic symphysis. 
      Pelvic ultrasound shows 2 viable intrauterine gestations, a single fundal placenta, and a thin intertwin membrane that meets the placenta at a 90-degree angle. 

      Among the below mentioned complications, this patient is at highest risk for which one to occur?

      Your Answer: Twin-twin transfusion syndrome

      Explanation:

      Twin gestations are generally at increased risk of complications and this risk is further stratified based on the chorionicity ie. number of placentas and amnionicity, the number of amniotic sacs of the gestation. In the given case patient has monochorionic diamniotic twins, which means 1 placenta and 2 amniotic sacs, based on the presence of 2 embryos, a single placenta and a thin intertwin membrane composed of 2 amniotic sacs that meets the placenta at a 90-degree angle (“T sign”). In patients who appear to have a single placenta, the base shape of the intertwin membrane distinguishes between a monochorionic (“T sign”) and fused dichorionic (“lambda sign”) gestation.
      Monochorionic twins are at high risk for twin-twin transfusion syndrome (TTTS), which is a complication that can result in heart failure and fetal
      eonatal mortality in both twins. In TTTS, unbalanced arteriovenous anastomoses are present between the shared placental vessels that supply the twins, because of these anastomoses, blood from the placental arteries from one twin (donor), which is of high resistance/pressure, is shunted into the placental veins of the other twin (recipient) with low resistance/pressure. This shunting of blood away from the donor twin causes anemia that leads to renal failure, oligohydramnios, low-output heart failure, and fetal growth restriction. In contrast, the shunting of blood toward the recipient twin causes polycythemia, which leads to polyhydramnios, cardiomegaly, high-output heart failure and hydrops fetalis. This in turn makes both twins at high risk for intrauterine and neonatal death.
      Mild TTTS is expectantly managed with serial ultrasounds to evaluate for worsening clinical features, whereas moderate-to-severe cases are treated with laser coagulation of the placental anastomoses.

      In monozygotic twins, placentation type is determined by timing of the twinning.  Twinning that occurs shortly after fertilization yields a dichorionic diamniotic gestation.  In contrast, the incomplete division (ie, fission) that can lead to conjoined twins occurs later in development and yields a monochorionic monoamniotic gestation. As the twins are in the same sac, monochorionic monoamniotic gestations can be complicated by cord entanglement but not possible in the given case as this patient has diamniotic twins.

      Risk factors for placenta accreta, implantation of the placenta directly into the myometrium, include placenta previa and prior uterine surgeries like cesarean delivery, myomectomy, etc

      Twin pregnancies are at increased risk of placenta previa (placental tissue that covers the internal cervical os); however, this patient has a fundal placenta, making this complication unlikely.

      Monochorionic twin gestations can be complicated by twin-twin transfusion syndrome, which is potentially a fatal condition that results from unbalanced vascular anastomoses between the vessels supplying umbilical cords of each twin.

    • A 40-year-old woman arrives at the hospital at eight weeks of her first pregnancy, anxious that her kid may have Down syndrome. Which of the following best reflects the risk of spontaneous abortion after an amniocentesis performed at 16 weeks?

      Your Answer: 18%

      Explanation:

      This question assesses critical clinical knowledge, as this information must be presented to a patient prior to an amniocentesis to ensure that she has given her informed permission for the treatment.
      Amniocentesis is most typically used for genetic counselling in the second trimester of pregnancy. Another option is to do a chorion-villus biopsy (CVB) between 10 and 11 weeks of pregnancy.
      The chances of miscarriage after both operations are roughly 1 in 200 for amniocentesis and 1 in 100 for CVB, according to most experts.
      The significance of this question is that professionals must be able to weigh the procedure’s danger against the risk of the sickness they are trying to identify.

    • A 32-year-old gravida 3 para 2 presents for routine prenatal care. The patient is at 14 weeks estimated gestational age by last menstrual period, and ultrasonography at 8 weeks gestation was consistent with these dates. Fetal heart tones are not heard by handheld Doppler. Transvaginal ultrasonography reveals an intrauterine foetus without evidence of fetal cardiac activity. The patient has not had any bleeding or cramping, and otherwise feels fine. A pelvic examination reveals a closed cervix without any signs of bleeding or products of conception.

      Which one of the following is the most likely cause of this presentation?

      Your Answer: A missed abortion

      Explanation:

      In this case, the patient has a missed abortion, which is defined as a dead foetus or embryo without passage of tissue and with a closed cervix. This condition often presents with failure to detect fetal heart tones or a lack of growth in uterine size.

      – By 14 weeks estimated gestational age, fetal heart tones should be detected by both handheld Doppler and ultrasonography.
      – An inevitable abortion presents with a dilated cervix, but no passage of fetal tissue.
      – A blighted ovum involves failure of the embryo to develop, despite the presence of a gestational sac and placental tissue.

      Your Answer: High dose folic acid for one month before conception and during first trimester

      Explanation:

      CDC urges all women of reproductive age to take 400 micrograms (mcg) of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain (anencephaly) and spine (spina bifida).

      The use of lamotrigine during pregnancy has not been associated with an increased risk of neural tube defects; however, the recommendation regarding higher doses of folic acid supplementation is often, but not always, broadened to include women taking any anticonvulsant, including lamotrigine.

      Your Answer: A Screening for HBV is not recommended for a pregnant woman with previous vaccination

      Explanation:

      The principal screening test for detecting maternal HBV infection is the serologic identification of HBsAg. Screening should be performed in each pregnancy, regardless of previous HBV vaccination or previous negative HBsAg test results.

      A test for HBsAg should be ordered at the first prenatal visit. Women with unknown HBsAg status or with new or continuing risk factors for HBV infection (e.g., injection drug use or a sexually transmitted infection) should be screened at the time of admission to a hospital or other delivery setting.

      Interventions to prevent perinatal transmission of HBV infection include screening all pregnant women for HBV, vaccinating infants born to HBV-negative mothers within 24 hours of birth, and completing the HBV vaccination series in infants by age 18 months.

      Your Answer: The risk is 1 in 4 (25%)

      Correct Answer:

      Explanation:

      Research suggests the risk of having preeclampsia again is approximately 20%, however experts cite a range from 5% to 80% depending on when you had it in a prior pregnancy, how severe it was, and additional risk factors you may have. If you had preeclampsia during your first pregnancy, you may get it again. HELLP is related to preeclampsia and about 4 to 12 percent of women diagnosed with preeclampsia develop HELLP. HELLP syndrome can also cause complications in pregnancy, and if you had HELLP in a previous pregnancy, regardless of the time of onset, you have a greater risk for developing it in future pregnancies.

    • A 28-year-old woman presents for an antenatal visit in her first pregnancy. The pregnancy has been progressing normally thus far. Her routine mid-trimester ultrasound examination, performed at 18 weeks of gestation, shows that the placenta occupies the lower part of the uterus. It is noted that the placenta is reaching to within 1 cm of the internal cervical os. The patient is wondering what this means for her pregnancy and what needs to be done about it.

      Which one of the following would be the most appropriate management?

      Your Answer: Repeat the ultrasound at 34 weeks of gestation.

      Explanation:

      This patient is presenting with a low-lying placenta at 18 weeks of gestation. This is a common finding on ultrasound at 18-20 weeks. If there is not bleeding, there is an 80-90% chance that by late pregnancy, the placenta will have moved and is no longer occupying the lower uterine segment. For this reason, the repeat ultrasound examination is usually performed at 32-34 weeks of gestation. Further discussions about management can then be made after obtaining those results.

      Leaving the repeat ultrasound until term would be inappropriate as intervention would be needed prior. If the placenta praevia is still present, it is typically advisable to deliver prior to term.

      Cardiotocographic (CT) fetal heart rate monitoring is not required in the absence of bleeding or other symptoms.

      Delivery by Caesarean section would not be necessary if the placenta was no longer praevia by the time the repeat ultrasound is done.

      Repeat ultrasound examination at 22 weeks of gestation would also unnecessary and inappropriate as it is too close in time for the change to occur.

    • A 40-year-old nulligravid woman comes to the office due to persistent abnormal uterine bleeding. Patient’s menstrual periods previously occurred monthly, which lasts of 4 days with moderate bleeding and light cramping. However, for the past 8 months, she has had intermenstrual spotting and bleeding which have occurred at varying intervals and last for 3-7 days. 
      Patient had started combination oral contraceptives 4 months ago, which has not improved the bleeding pattern. 

      On examination her temperature is 37.2 C (99 F), blood pressure is 126/76 mm Hg, pulse is 86/min and BMI is 29 kg/m2. 
      Speculum examination shows dark red blood in the posterior vaginal vault but no cervical or vaginal lesions. Remainder of the pelvic examination was normal. 
      Her laboratory results are as follows:
      - Hemoglobin: 12.2 g/dL
      - Prolactin: 5 ng/mL
      - TSH: 1.8 µU/mL
      - Urine pregnancy test is negative. 
      Pelvic ultrasound shows an anteverted uterus without any adnexal masses. 

      Which of the following is considered the best next step in management of this patient?

      Your Answer: Endometrial biopsy

      Explanation:

      Uncontrolled endometrial proliferation due to excess and unregulated estrogen is the reason for intermenstrual bleeding and irregular menses along with abnormal uterine bleeding (AUB) in this patient. The condition is mostly associated with an increased risk of endometrial hyperplasia
      ancer.
      The absolute risk of endometrial hyperplasia
      ancer is very low in women aged <45, therefore they can be started on combination medication with estrogen/progestin contraception (ie, medical management) without the evaluation of endometrium.  The estrogen component of medication regulates the menstrual cycle by build up the endometrium; whereas the progestin component helps in shedding of the endometrium.
      However, patients who have continued irregular menstrual bleeding even while on combination contraceptives require further evaluation as they have failed to improve with medical management. In such patients, the endometrial lining will be too thick for the progestin to completely shed during menstruation and this unshed endometrium continues to undergo dysregulated proliferation, leading to an increased risk of endometrial hyperplasia
      ancer. Therefore, patients age below 45 with AUB who have failed medical management require an endometrial biopsy.
      AUB persistent above 6 months, obesity, and/or tamoxifen therapy are the other indications for endometrial biopsy in women age <45, as all of these will increase the amount of unopposed endometrial estrogen exposure. In patients with heavy menstrual bleeding and anemia, coagulation studies are performed to evaluate for bleeding disorders like von Willebrand disease. It is not necessary in this patient as she have a normal hemoglobin level. In patients with heavy, but regular (ovulatory) bleeding an endometrial ablation, which is a procedure used to remove the excess endometrium, can be considered as the treatment option. Endometrial ablation is contraindicated in undiagnosed cases of AUB as it prevents evaluation of the endometrium in patients with possible endometrial hyperplasia
      ancer.

      To check for abnormalities of the uterus like didelphys or of the Fallopian tube like scarring, a hysterosalpingogram is used but it is not useful to evaluate AUB. In addition, as the procedure could spread cancerous endometrial cells into the abdominal cavity, hysterosalpingogram is contraindicated in cases of undiagnosed AUB.

      To evaluate secondary amenorrhea, ie. absence of menses for >6 months in a patient with previously irregular menses, a progesterone withdrawal test is used to determine whether amenorrhea is from low estrogen level, in negative cases there will be no bleeding after progesterone. This test is not indicated or relevant in this case as patient had continued bleeding while on oral contraceptives suggestive of high estrogen levels.

      Evaluation for endometrial hyperplasia
      ancer with an endometrial biopsy is required for those women age <45 with abnormal uterine bleeding who have failed medical management with oral contraceptives.

      Your Answer: Reassurance after thorough examination

      Explanation:

      The correct answer is reassurance after thorough examination. Most breast lesions diagnosed during pregnancy and lactation, even some specific ones such as lactation and adenoma galactocele, are benign. The diagnosis of breast cancer, which is difficult to elucidate and is less common among women who are pregnant or lactating than among those of the same age who are not, continues to be a challenge for clinicians.

    Correct

    • Among the following which will not be elevated in the third trimester of pregnancy?

      Your Answer: Serum free T4

      Explanation:

      Normally, there will be a slight raise in prolactin level throughout pregnancy even despite estrogen stimulating and progesterone inhibiting prolactin secretion.

      Serum alkaline phosphatase levels will be increased in pregnancy due to placental ALP.

      During the first trimester of pregnancy there is a physiological mechanism by hCG causing cross-stimulation of the TSH receptors and as a result of this the concentration of thyroid stimulating hormone (TSH) normally decreases. During second trimester TSH concentration will again return back to its pre-pregnancy levels and then rises slightly by the third trimester. However, most of the changes still occur within the normal non-pregnant range, and the serum free T3 and T4 concentrations remain unchanged throughout pregnancy. But the total concentrations, which include both free and protein-bound fractions, elevates significantly due to an increase in the circulating binding globulins.

      Iron binding capacity reflects transferrin, a protein used for iron transportation, which is a globulin found in the beta band on electrophoresis. To counteract the reduction of plasma iron during pregnancy both transferrin and iron binding capacity are elevated during this period.

      When compared to the non-pregnant level, cortisol levels are been elevated up to three times than normal.

    Correct

    • A 24-year-woman, gravida 2 para 1, 37 weeks of gestation, was admitted due to spontaneous rupture of membranes. Her previous pregnancy was uncomplicated and delivered at term via vaginal delivery. 24 hours since rupture of her membranes, no spontaneous labour was noted, hence a syntocinon/oxytocin infusion (10 units in 1L of Hartmann solution) was started at 3DmL/hour and increased to 120 mL over 9 hours. After 10 hours of infusion, during which Syntocinon dosage was increased to 30 units per litre, contractions were noted. Which is the most common complication of Syntocinon infusion?

      Your Answer: Fetal distress.

      Explanation:

      In this case, induction of labour at 37 weeks of gestation was necessary due to the absence of spontaneous of labour 24 hours after rupture of membranes. High doses of Syntocin and large volume of fluids may be required particularly when induction is done before term.

      Syntocin infusion can lead to uterine hypertonus and tetany which can result in fetal distress at any dosage. This is a common reason to decrease or stop the infusion and an indication for Caesarean delivery due to fetal distress

      Uterine rupture can occur as a result of Syntocin infusion especially when the accompanying fluids do not contain electrolytes, which puts the patient at risk for water intoxication.

      Maternal hypotension results from Syntocin infusion, not hypertension.

    Correct

    • A 41-year-old G2P1 woman who is at 30 weeks gestational age presented to the medical clinic for a routine OB visit. Upon history taking, it was noted that her first pregnancy was uncomplicated and was delivered 10 years ago. At 40 weeks then, she had a normal vaginal delivery and the baby weighed 3.17kg.
      In her current pregnancy, she has no complications and no significant medical history. She is a non-smoker and has gained about 11.3 kg to date. She also declined any testing for Down syndrome even if she is of advanced maternal age.

      Upon further examination and observation, the following are her results:
      Blood pressure range has been 100 to 120/60 to 70
      Fundal height measures only 25 cm

      Which of the following is most likely the reason for the patient’s decreased fundal height?

      Your Answer: Fetal growth restriction

      Explanation:

      A fundal height measurement is typically done to determine if a baby is small for its gestational age. The measurement is generally defined as the distance in centimetres from the pubic bone to the top of the uterus. The expectation is that after week 24 of pregnancy the fundal height for a normally growing baby will match the number of weeks of pregnancy — plus or minus 2 centimetres.

      A fundal height that measures smaller or larger than expected — or increases more or less quickly than expected — could indicate:
      – Slow fetal growth (intrauterine growth restriction)
      – A multiple pregnancy
      – A significantly larger than average baby (fetal macrosomia)
      – Too little amniotic fluid (oligohydramnios)
      – Too much amniotic fluid (polyhydramnios).

    • A 25 year-old lady presented with complaints of generalised pruritis during the 3rd trimester of her pregnancy. She was diagnosed as a case of intrahepatic cholestasis of pregnancy. Which one of the following factors carries the greatest risk to the foetus in this disease?

      Your Answer: Perinatal mortality

      Explanation:

      Intrahepatic cholestasis of pregnancy can affect both mother and foetus, however it is more harmful for the foetus. Amongst foetuses, there is an increased risk of perinatal mortality, meconium aspiration, premature delivery and post partum haemorrhage. Exact cause of fetal death cannot be predicted accurately but it is not related to intra uterine growth retardation or placental insufficiency. The liver can be affected in the mother leading to generalized pruritis but no evidence of fetal hepatic dysfunction has been found.

      Pelvic examination shows that her cervix is dilated by 4 cm and effaced 80%.

      What will be the most likely diagnosis in this case?

      Your Answer: Cervical insufficiency

      Explanation:

      This woman has signs and symptoms suggestive of cervical insufficiency, whose clinical features include pelvic pressure, premenstrual-like cramping and backache with increased vaginal discharge. Usually these symptoms will persist for several days to weeks.
      Cervical insufficiency is seen between 14 – 20 weeks of gestation, which is presented as soft effaced cervix, with minimal dilation on physical examination and a 4 cm dilated and more than 80% effaced cervix will be the clinical presentation in a more advanced case.

      Placental abruption presents with painful vaginal bleeding, whereas Placenta Previa presents as painless vaginal bleeding. Both cases will lead to shock but will not show any features of cervical insufficiency.

      Anaemia, polyhydramnios, large for gestational age uterus and severe hyperemesis gravidarum are the commonly associated symptoms of a twin pregnancies.

      New menstrual cycle after an abortion is expected to be presented with cervical dilation however signs of effacement will not be present along with it.

    Correct

    • A 25-year-old woman comes to your clinic for advice as she is 20 weeks pregnant and was found to have thyrotoxicosis with mild enlargement of the thyroid gland.

      What other investigation will you consider to be done in this patient?

      Your Answer: Ultrasound thyroid gland

      Explanation:

      A 20 weeks pregnant patient has developed goitre along with thyrotoxicosis, where the diagnosis of thyrotoxicosis has already been established.
      Ultrasound of the thyroid and a radioisotope scan to differentiate between “hot” and “cold” nodules are the confirming investigations for goitre. A nodule composed of cells that do not make thyroid hormone and the nodule which produces too much thyroid hormone are respectively called as cold and “hot” nodules.

      Due to the risk of fetal uptake of the isotope which leads to the damage of fetal thyroid, radioisotope or radionuclide Technetium uptake scan is contraindicated in pregnancy.

      Fine needle aspiration cytology is required to establish a histopathological diagnosis in case of all cold nodules.

      So ultrasound of the thyroid gland is the mandatory investigation to be done in this case as it will show diffuse enlargement, characteristic of the autoimmune disease, or multinodularity, which is suggestive of autonomous multinodular goitre.

      Your Answer: Send her to the local hospital for urgent review

      Explanation:

      This patient has developed clinical features like hypertension and proteinuria consistent with Pre-eclampsia. So the patient should be sent to an obstetrician for urgent review, it is not appropriate in such cases to postpone urgent specialist reviews as it could lead to serious complications.

    Correct

    • All of the following statements are considered correct regarding hypothyroidism in pregnancy, except:

      Your Answer: Thyroxin requirement does not increase in pregnancy and maintenance dose must be continued

      Explanation:

      Thyroid disease is the second most common endocrine disorder after diabetes in pregnancy. Thyroid disease poses a substantial challenge on the physiology of pregnant women and has significant maternal and fetal implications. Research shows during pregnancy, the size of the thyroid gland increases by 10% in countries with adequate iodine stores and by approximately 20% to 40% in countries with iodine deficiency. During pregnancy, thyroid hormone production increases by around 50% along with a similar increase in total daily iodine requirements.

      The different changes occurring in thyroid physiology are as follow:
      – An increase in serum thyroxine-binding globulin (TBG) leading to an increase in the total T4 and total T3 concentrations
      – Stimulation of the thyrotropin (TSH) receptor by human chorionic gonadotropin (hCG) which increases thyroid hormone production and subsequently reduces serum TSH concentration.

      Therefore, compared to the non-pregnant state, women tend to have lower serum TSH concentrations during pregnancy.
      The need to adjust levothyroxine dose manifests itself as early as at 4-8 weeks of gestation, therefore justifying the adjustment of levothyroxine replacement to ensure that maternal euthyroidism is maintained during early gestation. Most of well-controlled hypothyroid pregnant women need increased dosage of thyroid hormone after pregnancy.

      Your Answer: Elective caesarean delivery at 38 weeks of gestation

      Explanation:

      Breech presentation refers to the foetus in the longitudinal lie with the buttocks or lower extremity entering the pelvis first.

      The current recommendation for the breech presentation at term includes offering external cephalic version (ECV) to those patients that meet criteria, and for those whom are not candidates or decline external cephalic version, a planned caesarean section for delivery sometime after 39 weeks.

      What will be the most appropriate management in this patient during her pregnancy?

      Your Answer: Stop methotrexate and continue sulfasalazine

      Explanation:

      Rheumatoid arthritis and its prognosis during pregnancy are highly unpredictable, as the disease can improve in 75% of the cases and gets worse in 25%. During conception and pregnancy, it is advisable to avoid those rheumatoid arthritis medications which possess high risk in causing congenital disabilities. Most common such contraindicated remedies include methotrexate and leflunomide.
      Drugs like Prednisone, Non-steroidal anti-inflammatory drugs and TNF inhibitors are also not considered safe during pregnancy, so if required these should be used under specialist supervision.

      Sulfasalazine and Antimalarials such as hydroxychloroquine are safe and can be used without much complications during pregnancy. In this given case, the patient should be advised to stop methotrexate and to continue sulfasalazine during pregnancy.

    Correct

    • A 23-year-old woman, G1PO comes to your clinic at 12 week of pregnancy. She is complaining of mild vaginal bleeding for the past 12 hours, along with bouts of mild cramping lower abdominal pain.

      On vaginal examination, the cervical os is closed with mild discharge containing blood clots and an ultrasonography confirms the presence of a live fetus with normal heart rate.

      Which among of the following is the most likely diagnosis?

      Your Answer: Threatened abortion

      Explanation:

      Uterine bleeding in the presence of a closed cervix along with sonographic visualization of an intrauterine pregnancy with detectable fetal cardiac activity are diagnostic of threatened abortion.

      Abortion does not always follow a uterine bleeding in early pregnancy, sometimes not even after repeated episodes or large amounts of bleeding, that is why the term “threatened” is used in this case. In about 90 to 96% cases, the pregnancy continues after vaginal bleeding if occured in the presence of a closed os and a detectable fetal heart rate. Also as the gestational age advances its less likely the condition will end in miscarriage.

      In cases of inevitable abortion, there will be dilatation of cervix along with progressive uterine bleeding and painful uterine contractions. The gestational tissue can be either felt or seen through the cervical os and the passage of this tissue occurs within a short time.

      In case were the membranes have ruptured, partly expelling the products of conception with a significant amounts of placental tissue left in the uterus is called as incomplete abortion. During the late first and early second trimesters this will be the most common presentation of an abortion. Examination findings of this includes an open cervical os with gestational tissues observed in the cervix and a uterine size smaller than expected for gestational age and a partially contracted uterus. The amount of bleeding will vary but can be severe enough to cause hypovolemic shock, with painful contractions and an ultrasound revealing tissues in the uterus.

      An in utero death of the embryo or fetus prior to 20 weeks of gestation is called as a missed abortion. In this case the women may notice that the symptoms associated with early pregnancy like nausea, breast tenderness, etc have disappeared and they don’t ‘feel pregnant’ anymore. Vaginal bleeding may occur but the cervix remains closed and the ultrasound done reveals an intrauterine gestational sac with or without an embryonic/fetal pole, but no embryonic/fetal cardiac activity will be noticed.

      In case of complete abortion, miscarriage occurs before the 12th week and the entire contents of conception will be expelled out of uterus. If this case, the physical examination will show a small and well contracted uterus with an open or closed cervix. There is scant vaginal bleeding with only mild cramping and ultrasound will reveal an empty uterus without any extra-uterine pregnancy.

      Which of the following is considered to be the most appropriate course of action for the patient?

      Your Answer: Antiviral therapy and pelvic ultrasound

      Explanation:

      Chickenpox or varicella is a contagious disease caused by the varicella-zoster virus (VZV). The virus is responsible for chickenpox (usually primary infection in non-immune hosts) and herpes zoster or shingles (following reactivation of latent infection). Chickenpox results in a skin rash that forms small, itchy blisters, which scabs over. It typically starts on the chest, back, and face then spreads. It is accompanied by fever, fatigue, pharyngitis, and headaches which usually last five to seven days. Complications include pneumonia, brain inflammation, and bacterial skin infections. The disease is more severe in adults than in children.

      Primary varicella infection during pregnancy can also affect the foetus, who may present later with chickenpox. In pregnant women, antibodies produced as a result of immunization or previous infection are transferred via the placenta to the foetus. Varicella infection in pregnant women could spread via the placenta and infect the foetus. If infection occurs during the first 28 weeks of pregnancy, congenital varicella syndrome may develop. Effects on the foetus can include underdeveloped toes and fingers, structural eye damage, neurological disorder, and anal and bladder malformation.

      Prenatal diagnosis of fetal varicella can be performed using ultrasound, though a delay of 5 weeks following primary maternal infection is advised.

      Antivirals are typically indicated in adults, including pregnant women because this group is more prone to complications.

    Correct

    • Fetal distress commonly occurs when the head is in the occipito-posterior (OP) position during labour. Which of the following statements is the most probable explanation for this?

      Your Answer: Incoordinate uterine action.

      Explanation:

      Incoordinate uterine action almost always results in fetal distress due to increased resting intrauterine pressure. All other statements can also cause fetal distress, however, these are not as common as incoordinate uterine action. Syntocin infusion for labour augmentation and administration of epidural anaesthetic for pain relief can also increase the risk of fetal distress.
      Cardiotocograph (CTG) monitoring during labour is highly recommended in patients where the fetal head is found in the OP position. Moreover, it is mandatory when there is Syntocin infusion or epidural anaesthesia.

    Correct

    • A 28-year-old woman presents in early labour. She is healthy and at full-term.

      Her pregnancy has progressed well without any complications.

      She indicates that she would like to have a cardiotocograph (CTG) to assess her baby as she has read about its use for foetal monitoring during labour.

      What advice would you give her while counselling her regarding the use of CTG compared to intermittent auscultation during labour and delivery?

      Your Answer: There is no evidence to support admission CTG.

      Explanation:

      In high-risk pregnancies, continuous monitoring of foetal heart rate is considered mandatory.

      However, in low-risk pregnancies, cardiotocograph (CTG) monitoring provides no benefits over intermittent auscultation.

      A significant issue with CTG monitoring is that apparent abnormalities are identified that usually have minimal clinical significance, but can prompt the use of several obstetric interventions such as instrumental deliveries and Caesarean section. In low risk patients, such interventions may not even be required.

      CTG monitoring has not been shown to reduce the incidence of cerebral palsy or other neonatal developmental abnormalities, nor does it accurately predict previous foetal oxygenation status unless the CTG is significantly abnormal when it is first connected.

      Similarly, CTG cannot accurately predict current foetal oxygenation unless the readings are severely abnormal.

      Therefore, there is no evidence to support routine admission CTG (correct answer).

    • A 37-year-old female at her 33 weeks of gestation who sustains a road traffic accident at 90 km/hour, is taken to the emergency department.

      On examination, she is found to be pale, with a heart rate of 112 bpm, blood pressure of 95/55 mm of Hg, respiratory rate of 18 breaths per minute and her oxygen saturation in room air is 95%. Fetal heart rate is audible at 102 bpm and her uterus is tense and tender, she denied having any direct trauma to the abdomen.

      Which one of the following is the most likely diagnosis in this given case?

      Your Answer: Placental abruption

      Explanation:

      This patient presents with signs and symptoms similar to clinical features of placental abruption.

      Any trauma during the last trimester of pregnancy could be dangerous to both mother and fetus. By force of deceleration, motor vehicle accidents can result in placental separation. Also when subjected to strong acceleration-deceleration forces such as those during a motor vehicle crash uterus is thought to slightly change its shape. Since the placenta is not elastic and amniotic fluid is not compressible, such uterine distortion caused due to acceleration-deceleration or direct trauma will result in abruptio placentae due to shear stress at the utero-placental interface.

      A painful, tender uterus which is often contracting is characteristic of placental abruption and the condition will lead to maternal hypovolemic hypotension and consequent fetal distress which is presented as fetal bradycardia and repetitive late decelerations. Vaginal bleeding, abdominal pain, contractions, uterine rigidity with tenderness, and a nonreassuring fetal heart rate (FHR) tracing are the clinical features diagnostic of abruption. However, a significant abruption can occasionally be asymptomatic or associated with minimal maternal symptoms in the absence of vaginal bleeding. Therefore the amount of vaginal bleeding is not always an appropriate indicator to the severity of placental abruption, this is because, in cases bleeding could be very severe or it may be concealed in the form of a hematoma in between the uterine wall and the placenta.

      Sharp or blunt abdominal trauma can lead to uterine rupture or penetrating injury, since there is no reported abdominal trauma to the patient, uterine rupture is less likely to happen in this case. Severe abdominal pain with tenderness, cessation of contractions and loss of uterine tone are the most common symptoms characteristic of Uterine rupture. It will also be associated with mild to moderate vaginal bleeding along with fetal bradycardia or loss of heart sound. In this case uterus will be less tense and tender in comparison to placental abruption

      Symptoms like low blood pressure, tachycardia and fetal bradycardia can be justified by ruptured spleen and liver laceration, but not the tense, tender and contracting uterus.

      The diagnosis of placenta previa cannot be considered with the given clinical picture as it presents with sudden, painless bleeding of bright red blood and there will not be any uterine tenderness.

    Correct

    • A patient, in her third pregnancy with a history of two consecutive spontaneous abortions, presents at 12 weeks of gestation. She has had regular menstrual cycles, lasting 30 days in duration. Just prior to coming for her assessment, she reports passing a moderate amount of blood with clots per vaginally along with some intermittent lower abdominal pain. On examination, her cervical canal readily admitted one finger. Bimanual palpation found a uterus corresponding to the size of a pregnancy of 8 weeks’ duration.

      Which is the most appropriate next step in managing this patient?

      Your Answer: Vaginal ultrasound.

      Explanation:

      It is essential to notice the important details mentioned in the case scenario. These would be the details about her menstruation, a smaller than dates uterus and an open cervix. A smaller than expected uterine size could be caused by her passing out some tissue earlier or it could be due to the foetus having been dead for some time. The finding of an open cervix would be in line with the fact that she had passed out some fetal tissue or it could signify that she is experiencing an inevitable miscarriage (while all fetal tissue is still kept within her uterus).

      The likely diagnoses that should be considered for this case would be miscarriage (threatened, incomplete, complete and missed), cervical insufficiency, and ectopic pregnancy. A smaller than dates uterus and an open cervix makes threatened abortion an unlikely diagnosis. Her clinical findings could be expected in both an incomplete abortion and a complete abortion.
      In ectopic pregnancy, although there would be a smaller than dates uterus, the cervical os would usually be closed. Cervical insufficiency is probable due to an open os but the uterine size would be expected to correspond to her dates, making it also less likely than a miscarriage.

      Since she most likely has had a miscarriage (be it incomplete or complete), the next best step would be to do a per vaginal ultrasound scan which could show whether or not products of conception are still present within the uterine cavity. If present, it would be an incomplete miscarriage which would warrant a dilatation and curettage; if absent, it is a complete miscarriage so D&C would not be needed.

      In view of her open cervix and 12 weeks of amenorrhea, there is no indication for a pregnancy test nor assessment of her beta-hCG levels. Cervical ligation would only be indicated if the underlying issue was cervical incompetence, which is not in this case.

      Explanation:

      A rectovaginal swab taken for Group B streptococci culture should be done in women presenting with threatened preterm labour

      If labour is establishes, intrapartum antibiotic prophylaxis for Group B streptococci should be commenced and continued until delivery. In cases were labour is not establish, prophylaxis for Group B streptococci should be ceased and should be re-established only if the culture is found to be positive, that too at the time of onset of labour.

      Strategies acceptable for reducing early onset Group B streptococci sepsis includes universal culture-based screening using combined low vaginal plus or minus anorectal swab at 35-37 weeks gestation or a clinical risk factor based approach.

      No additional prophylaxis is recommended irrespective of Group B streptococci carriage, for elective cesarean section before the commencement of labour. However, if a woman who commences labour or has spontaneous rupture of the membranes before her planned Caesarean section is screened positive for Group B streptococci, she should receive intrapartum antibiotic prophylaxis while awaiting delivery.

      Although there is little direct evidence to guide this practice, consideration of the above mentioned evidences it is recommendation that, every women with unknown Group B streptococci status at the time of delivery should be managed according to the presence of intrapartum risk factors.
      All women at increased risk of early onset Group B streptococci sepsis must be offered an intrapartum antibiotic prophylaxis with IV penicillin-G or ampicillin.

    Correct

    • A 33-year-old woman was admitted to a hospital's maternity unit for labour. Her pregnancy has been unremarkable so far and she had regular antenatal visits. Meconium liquor passage was noted during the labour. Cardiotocography was done and revealed a fetal heart rate (FHR) of 149bpm. There were no noted decelerations or accelerations. The beat-to-beat variability is established at 15 bpm. Upon vaginal examination, there were no reported abnormalities.

      Which of the following is considered to be the next most appropriate step in managing this patient?

      Your Answer: The CTG is normal and close monitoring until delivery is all required for now

      Explanation:

      Meconium is the earliest stool of a newborn. Occasionally, newborns pass meconium during labour or delivery, resulting in a meconium-stained amniotic fluid (MSAF).

      No particular cardio-tocograph pattern can be considered to have a poor prognostic value in the presence of thick MSAF and the decision to deliver and the mode of delivery should be based on the overall assessment and the stage and progress of labour. While management should be individualized, a higher Caesarean section rate in thick MSAF can be justified to ensure a better outcome for the neonate even in the presence of a normal CTG trace.

    Correct

    • Three days after a lower uterine Caesarean section delivery (LSCS) for fetal distress, a 24-year-old woman develops fever with a temperature of 37.9°C. Intraoperative notes show that she was administered one dose of prophylactic antibiotics. She had been afebrile during the post-partum period until today.

      Which is the least likely cause of her fever?

      Your Answer: A deep venous thrombosis (DVT).

      Explanation:

      This question is about the differential diagnoses that should be considered if a patient presents with postpartum fever. The work-up for such patients would usually involve vaginal swabs, midstream urine culture and sensitivity and an ultrasound scan of the wound to look for any presence of a haematoma. LSCS is a major surgery and one common cause of puerperal fever would be surgical site infection. It is not surprising that women who deliver via LSCS are at higher risk of developing post-partum fever compared to those who deliver vaginally. Other common causes include endometritis and UTI. Ultrasound examination of the pelvic deep venous system and the legs would also be done to look for any thrombosis. Deep vein thrombosis can occur due to immobility, however it is unlikely to present with fever.

    Correct

    • An 8 week pregnant female presents to the ob-gyn with bleeding from the vagina for the last two days. Bimanual examination reveals the uterus to be 8 weeks in size. On speculum examination, the cervical os is closed. How would the fetal viability be confirmed?

      Your Answer: Transvaginal ultrasound

      Explanation:

      Indication for a transvaginal ultrasound during pregnancy include:
      – to monitor the heartbeat of the foetus
      – look at the cervix for any changes that could lead to complications such as miscarriage or premature delivery
      – examine the placenta for abnormalities
      – identify the source of any abnormal bleeding
      – diagnose a possible miscarriage
      – confirm an early pregnancy

      This is an ultrasound examination that is usually carried out vaginally at 6-10 weeks of pregnancy.

      The aims of this scan are to determine the number of embryos present and whether the pregnancy is progressing normally inside the uterus.

      This scan is useful for women who are experiencing pain or bleeding in the pregnancy and those who have had previous miscarriages or ectopic pregnancies.

    • A 40-year-old woman who is at 34 weeks of pregnancy presented to the medical clinic for advice since her other two children were diagnosed with whooping cough just 8 weeks ago, she is worried for her newborn about the risk of developing whooping cough.

      Which of the following is considered the most appropriate advice to give to the patient?

      Your Answer: Give Pertussis vaccine booster DPTa now

      Explanation:

      To help protect babies during this time when they are most vulnerable, women should get the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) during each pregnancy.

      Pregnant women should receive Tdap anytime during pregnancy if it is indicated for wound care or during a community pertussis outbreak.
      If Tdap is administered earlier in pregnancy, it should not be repeated between 27 and 36 weeks gestation; only one dose is recommended during each pregnancy.

      Optimal timing is between 27 and 36 weeks gestation (preferably during the earlier part of this period) to maximize the maternal antibody response and passive antibody transfer to the infant.
      Fewer babies will be hospitalized for and die from pertussis when Tdap is given during pregnancy rather than during the postpartum period.

    Incorrect

    • A 25-year-old gravida 1 para 0 woman, at her 36 weeks of gestation, is brought to the emergency department by her mother due to a seizure. Patient was sitting outside when she suddenly had a 2-minute seizure with loss of urinary continence and is still confused when she arrived at the emergency department. Her mother reports that the patient had severe anxiety and had been acting out for the past several days. Her only surgery was a splenectomy after a motor vehicle collision last year. 

      On physical examination patient's temperature is 37.7 C (99.9 F), blood pressure is 158/98 mm Hg, and pulse is 120/min. Patient seems agitated and diaphoretic with bilaterally dilated pupils. 

      On systemic examination:
      Cranial nerves are intact, neck is supple and nontender. 
      Cardiopulmonary examination is normal. 
      The abdomen is gravid without any rebound or guarding and the uterus is nontender. 
      There is 2+ pitting pedal edema bilaterally.  Sensations and strength are normal in the bilateral upper and lower extremities. 

      Laboratory results are as follows:
      a) Complete blood count shows
      - Hematocrit: 33%
      - Platelets: 140,000/mm3
      - Leukocytes: 13,000/mm3
      b) Serum chemistry

      - Protein: none
      - Ketones: present

      CT scan of the head is normal. 

      Which of the following is most likely the diagnosis in this patient?

      Your Answer: Hemolysis, elevated liver enzymes, low platelet count syndrome

      Correct Answer: Amphetamine intoxication

      Explanation:

      This patient at 36 weeks of gestation likely had a generalized tonic-clonic seizure. A new-onset seizures in pregnancy can be due to either due to eclampsia which is pregnancy-specific or due to other non-obstetric causes like meningitis, intracranial bleeding etc.

      In pregnant and postpartum women eclampsia is the most common cause for seizures which is classically associated with preeclampsia, a new-onset hypertension at ≥20 weeks gestation, with proteinuria and/or signs of end-organ damage. Although this patient has hypertension, absence of proteinuria and the additional findings like agitation, dilated pupils, hyponatremia and normal head CT scan are suggestive of another etiology. Patients with eclampsia will show white matter edema in head CT scan.

      Amphetamine intoxication, which causes overstimulation of the alpha-adrenergic receptors resulting in tachycardia, hypertension and occasional hyperthermia, might be the cause for this patient’s seizures. Some patients will also have diaphoresis and minimally reactive, dilated pupils and severe intoxication can lead to electrolyte abnormalities, including significant hyponatremia (possibly serotonin-mediated) and resultant seizure activity.
      Confirmation of Amphetamine intoxication can be done by a urine drug testing. it is essential to distinguishing between eclampsia and other causes of seizure in this case, as it will help to determine whether or not there is need for an emergency delivery.

      Altered mental status and electrolyte abnormalities can be due to heat stroke, however, patients affected this way will have an elevated temperature of >40 C /104 F associated with hemodynamic instabilities like hypotension.

      Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a hypertensive disorder of pregnancy which can result in seizures (ie, eclampsia), but this patient’s hematocrit level is normal without any hemolysis, also patients with HELLP syndrome typically presents with a platelet count <100,000/mm3. Seizures and altered mental status in patients with prior splenectomy can be due to pneumococcal meningitis however, such patients will present with high fever and nuchal rigidity, making this diagnosis less likely in the given case. Amphetamine intoxication can present with hypertension, agitation, diaphoresis, dilated pupils, and a generalized tonic-clonic seizure due to hyponatremia, which is most likely to be the case here.

    Correct

    • A 32-year-old woman, at 37 weeks of gestation, presents to the emergency department due to sudden onset of severe abdominal pain with vaginal bleeding of approximately 1200 cc and cessation of contractions after 18 hours of active pushing at home. Her pregnancy has been uneventful until the event.

      On examination, patient is conscious and pale, with a blood pressure of 70/45 mm of Hg and pulse rate of 115 bpm. Abdomen is found to be irregularly distended with shifting dullness and fluid thrill. Fetal heart sounds are not audible.

      Which among of the following will most likely be her diagnosis?

      Your Answer: Uterine rupture

      Explanation:

      The given case where the patient presents with sudden abdominal pain, cessation of uterine contraction and the urge to push along with vaginal bleeding is typical for uterine rupture. Examination shows a decreased or lost fetal heart rate, along with signs of fluid collection including fluid thrill and shifting dullness due to the entry of blood into the peritoneal cavity.
      Other common manifestations of uterine rupture include:
      – Loss of the station of the fetal presenting part
      – Vaginal bleeding which is not be proportionate to the hemodynamic status
      -Maternal tachycardia and hypotension ranging from subtle to severer shock
      – Uterine tenderness
      – Change in uterine shape and contour
      – Easily palpable fetal parts
      – No fetal presentation on vaginal examination
      – Hematuria if the rupture extends to the bladder
      Anterior lower transverse segment is the most common site of spontaneous uterine rupture.

      Placenta previa usually presents as painless vaginal bleeding, which rules it out as the diagnosis in given case.

      Vaginal bleeding with a tender and tense uterus is the presentation in placental abruption, also contrary to uterine rupture, uterine contractions will continue in case of placental abruption.

      Cervical laceration can be a possibility, but in such cases more amount of vaginal blood loss was expected in this patient with hemodynamic instability. Also symptoms like deformed uterus, abdominal distention and cessation of contractions are inconsistent with cervical laceration.

      Excessive generation of thrombin and fibrin in the circulating blood results in Disseminated intravascular coagulation (DIC) which leads to increased platelets aggregation and consumption of coagulation factors resulting in consequent bleeding at one site and thromboembolism at another. Placental abruption and retained products of conception in the uterine cavity are the most common obstetric causes of DIC. The condition will not fit as diagnosis in this clinical scenario.
