Question 1
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.

Question 2
Correct

A 32-year-old mother with a 9-year-old child is considering having a second child. Her first pregnancy was complicated by puerperal psychosis. Following electroconvulsive therapy (ECT), she promptly recovered and has been well until now. She is in excellent health and her husband has been very supportive. According to patient files, she was noted to be an excellent mother.
What would be the most appropriate advice?Your Answer: There is a 15-20% chance of recurrence of psychosis postpartum.
Explanation:Puerperal psychosis seems to be mainly hereditary and closely associated with bipolar disorder especially the manic type, rather than being a distinct condition with a group of classical symptoms or course. Postpartum psychoses typically have an abrupt onset within 2 weeks of delivery and may have rapid progression of symptoms. Fortunately, it is generally a brief condition and responds well to prompt management. If the condition is threatening the mother and/or baby’s safety, hospital admission is warranted. A patient can present with a wide variety of psychotic symptoms ranging from delusion, passivity phenomenon, catatonia, and hallucinations. While depression and mania may be the predominating features, it is not surprising to see symptoms such as confusion and stupor. Although the rate of incidence is about 1 in 1000 pregnancies, it is seen in about 20% of women who previously had bipolar episodes prior to pregnancy. It has not been shown to be linked with factors such as twin pregnancies, stillbirth, breastfeeding or being a single parent. However, it might be more commonly seen in women who are first-time mothers and pregnancy terminations.
The risk of recurrence is 20%. Unfortunately, there is no specific treatment guideline but organic causes should first be ruled out. First generation/typical anti-psychotics are often associated with extrapyramidal symptoms. Nowadays, atypical antipsychotics such as risperidone or olanzapine can be used along with lithium which is a mood stabiliser. As of now, there hasn’t been any significant side effects as a result of second generation antipsychotic use in pregnancy. While women are usually advised to stop breast-feeding, it might be unnecessary except if the mother is being treated with lithium which has been reported to cause side effects on the infants in a few instances. ECT is considered to be highly efficacious for all types of postpartum psychosis and may be necessary if the mother’s condition is life-threatening to herself or/and the baby. If untreated, puerperal psychosis might persist for 6 months or even longer.
The options of saying ‘in view of her age and previous problem, further pregnancies are out of the question’ and so is ‘By all means start another pregnancy and see how she feels about it. If she has misgivings, then have the pregnancy terminated.’ are inappropriate.
As mentioned earlier, considering there is a 20% chance of recurrence it is not correct to say that since she had good outcomes with her first pregnancy, the risk of recurrence is minimal.
Anti-psychotics are not recommended to be used routinely both during pregnancy and lactation due to the absence of long-term research on children with intrauterine and breastmilk exposure to the drugs. Hence it is not right to conclude that ‘if she gets pregnant then she should take prophylactic antipsychotics throughout the pregnancy’ as it contradicts current guidelines. Each case should be individualised and the risks compared with the benefits to decide whether anti-psychotics should be given during pregnancy. It is important to obtain informed consent from both the mother and partner with documentation.
Should the mother deteriorates during the pregnancy that she no longer is capable of making decisions about treatment, then an application for temporary guardianship should be carried out to ensure that she can be continued on the appropriate treatment.

Question 3
Correct

A 61-year-old woman comes to the office for a breast cancer follow-up visit. She recently underwent right mastectomy for a node-negative, estrogen- and progesterone-receptor-positive tumor. She was on an aromatase inhibitor as adjuvant therapy, which was discontinued due to severe fatigue and poor sleep. At present, she is scheduled for a 5-year course of adjuvant therapy with tamoxifen. Patient has no other chronic medical conditions and her only medication is a daily multivitamin. Her last menstrual period was 8 years ago. Patient's father had a myocardial infarction at the age 64; otherwise her family history is noncontributory. She does not use tobacco, alcohol, or any other illicit drugs.
On examination her vital signs seems stable, with a BMI of 21 kg/m2.
Patient has many concerns about tamoxifen therapy and asks about potential side effects. Which among the following complications mentioned below is this patient at greatest risk of developing, due to tamoxifen therapy?Your Answer: Hyperplasia of the endometrium
Explanation:Tamoxifen and Raloxifene are drugs which acts as selective estrogen receptor modulators.
Their mechanisms of action are competitive inhibitor of estrogen binding and mixed agonist/antagonist action respectively.
Commonly indicated in prevention of breast cancer in high-risk patients. Tamoxifen as adjuvant treatment of breast cancer and Raloxifene in postmenopausal osteoporosis.
Adverse effects include:
– Hot flashes
– Venous thromboembolism
– Endometrial hyperplasia & carcinoma (tamoxifen only)
– Uterine sarcoma (tamoxifen only)
Adjuvant endocrine therapy is commonly used option for treatment of nonmetastatic, hormone-receptor-positive breast cancer; and the most commonly used endocrine agents include tamoxifen, aromatase inhibitors, and ovarian suppression via GnRH agonists or surgery.Tamoxifen is a selective estrogen receptor modulator which is an estrogen receptor antagonist in the breast. It is the most preferred adjuvant treatment for pre-menopausal women at low risk of breast cancer recurrence. Tamoxifen is also a second-line endocrine adjuvant agent for postmenopausal women who cannot use aromatase inhibitor therapy due to intolerable side effects.
Tamoxifen acts as an estrogen agonist in the uterus and stimulates excessive proliferation of endometrium. Therefore, tamoxifen use is associated with endometrial polyps in premenopausal women, and endometrial hyperplasia and cancer in postmenopausal women. These effects will continue throughout the duration of therapy and resolves once the treatment is discontinued. Even with all these possible complications, benefits of tamoxifen to improve the survival from breast cancer outweighs the risk of endometrial cancer.In postmenopausal women, tamoxifen has some estrogen-like activity on the bone, which can increase bone mineral density and thereby reduce the incidence of osteoporosis significantly. However, tamoxifen is generally not a first-line agent for osteoporosis in treatment due to the marked risk of endometrial cancer.
Dysplasia of the cervical transformation zone is typically caused due to chronic infection by human papillomavirus, and tamoxifen has no known effects on the cervix.
Tamoxifen is not associated with any increased risk for adenomyosis, which is characterised by ectopic endometrial tissue in the myometrium.
Intimal thickening of the coronary arteries is a precursor lesion for atherosclerosis. Tamoxifen helps to decrease blood cholesterol level and thereby protect against coronary artery disease.
Tamoxifen is an estrogen antagonist on breast tissue and is used in the treatment and prevention of breast cancer, but it also acts as an estrogen agonist in the uterus and increases the risk of development of endometrial polyps, hyperplasia, and cancer.

A 23-year-old woman at 36 weeks of gestation in her first pregnancy presents for headache and right upper quadrant abdominal pain for three days. The pregnancy has been normal and unremarkable until now.
Her blood pressure is 145/90 mmHg and urinalysis shows protein ++. On physical exam, her ankles are slightly swollen. There is slight tenderness to palpation under the right costal margin.
Which one of the following is the most likely diagnosis?Your Answer: Pre-eclampsia.
Explanation:There are a few differential diagnoses to think of in a patient that presents such as this one. Pre-eclampsia, cholecystitis, and fatty liver could all cause pain and tenderness, but cholecystitis would not normally cause the hypertension and proteinuria seen in this patient and neither would acute fatty liver of pregnancy. The more likely explanation is pre-eclampsia which must always be considered in the presence of these symptoms and signs. This process is particularly severe in the presence of pain and tenderness under the right costal margin due to liver capsule distension.
Chronic renal disease could cause the hypertension and mild proteinuria seen, but it would not usually produce the pain and tenderness that this patient has unless it was complicated by severe pre-eclampsia.
Biliary cholestasis does not usually produce pain.

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: Anti-thyroid antibodies
Correct 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.

A 36-year-old woman is brought to the emergency department after she twisted her ankle, once initial management of her current problem is done, you realize that she is 10 weeks pregnant.
On further questioning, she admits to heroin addiction and says that Doc, I sometimes need to get high on meth, but my favorite wings to fly are cocaine though, since I cannot afford it, I take a bit when I manage to crash a party. She also drinks a bottle of whisky every day. During the past few weeks, she started worrying about not being a good mother, and for this she is taking diazepam at night which she managed to get illegally.
Considering everything this patient revealed, which is most likely to cause fetal malformations?Your Answer: Alcohol
Explanation:Woman in the given case is taking a full bottle of Whisky every day. As per standards, a small glass of Whisky (1.5 Oz) is equivalent of a standard drink and a bottle definitely exceeds 12 standard drinks. This makes her fetus at significant risk for fetal alcohol syndrome (FAS) which is associated with many congenital malformations. Low-set ears, midfacial hypoplasia, elongated philtrum, upturned nose and microcephaly along with skeletal and cardiac malformations are the congenital malformations commonly associated with fetal alcohol syndrome.
Health risks of benzodiazepines during pregnancy has not been clearly established, but there are inconsistent reports of teratogenic effects associated with fetal exposure to benzodiazepines. Neonatal abstinence syndrome of delayed onset can be associated with regular use of benzodiazepine in pregnancy.
Use of Amphetamine in controlled doses during pregnancy is unlikely to pose a substantial teratogenic risk, but a range of obstetric complications such as reduced birth weight and many these outcomes which are not specific to amphetamines but influenced by use of other drug and lifestyle factors in addition to amphetamine are found commonly among women who use it during pregnancy. Exposure to amphetamines in utero may influence prenatal brain development, but the nature of this influence and its potential clinical significance are not well established.
3,4- methylenedioxymetham phetamine(MOMA), which is an amphetamine derivative and commonly known as ecstasy, have existing evidences suggesting that its use during first trimester poses a potential teratogenic risk. So it is strongly recommended to avoided the use of ecstasy during 2-8 weeks post conception or between weeks four to ten after last menstrual period as these are the considered periods of organogenesis.
Role of cocaine in congenital malformations is controversial as cases reported of malformations caused by cocaine are extremely rare. However, it may lead to fetal intracranial haemorrhage leading to a devastating outcome.
Opiate addictions carry a significant risk for several perinatal complications, but it has no proven association with congenital malformation.

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 25-year-old woman at 39 weeks of gestation complaints of intermittent watery vaginal discharge, which has started last night after she had sex with her husband.
Speculum examination shows, pooling of straw-colored fluid in the posterior vaginal fornix. The cervical os is closed and there is leaking of liquor from cervical os when she is asked to cough or strain.
Which among the following best explains these clinical findings?Your Answer: Premature rupture of membranes (PROM)
Explanation:Presentation in the given case is classic for premature rupture of membranes (PROM) which was probably caused due to trauma during intercourse.
Premature rupture of membrane (PROM) is defined as the rupture of embryonic membranes before the onset of labor, regardless of the age of pregnancy. If occured before 37 weeks of gestation, it is termed as preterm PROM (PPROM.)A sudden gush of watery fluid per vagina is the classic presentation of rupture of the membranes (ROM), regardless of gestational age, however nowadays many women presents with continuous or intermittent leakage of fluid or a sensation of wetness within the vagina or on the perineum. Presence of liquor flowing from the cervical os or its pooling in the posterior vaginal fornix are considered as the pathognomonic symptom of ROM. Assessment of fetal well-being, the position of the fetus, placental location, estimated fetal weight and presence of any anomalies in PROM and PPROM are done with ultrasonographic studies.
Retained semen will not result in the findings mentioned in this clinical scenario as it have a different appearance.
Infections will not be a cause for this presentation as it will be associated with characteristic features like purulent cervical discharge, malodorous vaginal discharge, etc. Pooling of clear fluid in the posterior fornix is pathognomonic for ROM.
Urine leakage is common during the pregnancy, but it is not similar to the clinical scenario mentioned above.
Absence of findings like cervical dilation and bulging membranes on speculum exam makes cervical insufficiency an unlikely diagnosis in this case.

A 23-year-old primigravida who is at 41 weeks has been pushing for the past 2 and a half ours. The fetal head is at the introitus and is beginning to crown already. An episiotomy was seen to be necessary. The tear was observed to extend through the sphincter of the rectum but her rectal mucosa remains intact.
Which of the following is the most appropriate type of episiotomy to be performed?Your Answer: Third-degree
Explanation:The episiotomy is a technique originally designed to reduce the incidence of severe perineal tears (third and fourth-degree) during labour. The general idea is to make a controlled incision in the perineum, for enlargement of the vaginal orifice, to facilitate difficult deliveries.
Below is the classification scale for the definitions of vaginal tears:
First degree involves the vaginal mucosa and perineal skin with no underlying tissue involvement.
Second degree includes underlying subcutaneous tissue and perineal muscles.
Third degree is where the anal sphincter musculature is involved in the tear. The third-degree tear can be further broken down based on the total area of anal sphincter involvement.
Fourth degree is where the tear extends through the rectal muscle into rectal mucosa. -

A 28-year-old, 10-weeks pregnant woman comes to you complaining of right iliac fossa pain, which is more when she tries to stand up or cough. She also had a history of appendectomy, done 12 years ago.
Physical examination reveals mild tenderness in right iliac fossa, without any rebound tenderness or guarding.
Among the following options which will be the most likely diagnosis?Your Answer: Complex ovarian cyst rupture
Correct Answer: Round ligament pain
Explanation:The given case can be diagnosed as round ligament pain, which is common during pregnancy. This happens as a result to the stretching of round ligament in pelvis to occupy the growing uterus. The round ligament pain usually gets worse with movements or straining and will be relieved by rest or warm application.
As the abdominal examination of patient is unremarkable, conditions like ovarian cyst rupture, ectopic pregnancy and intestinal obstruction are a very unlikely to be the diagnosis.

A 21-year-old woman has been stable on medicating with lamotrigine after developing epilepsy 2 years ago. She is planning to conceive but is concerned about what her medications may do to her baby.
Which of the following is considered to reduce the incidence of neural tube defects?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.

Lidiya is a 30-year-old hospital nurse in her nine weeks of pregnancy. She has no history of chickenpox, but by regularly attending the facial sores of an elderly patient with herpes zoster ophthalmicus she has been significantly exposed to shingles.
What would you advise her as preventive management?Your Answer: Give Varicella Zoster Immunoglobulins as soon as possible
Correct Answer: If she had chicken pox immunization in the past, she needs to have her Varicella-Zoster IgG antibodies checked to assure immunity
Explanation:Patient in the given case is nine weeks pregnant, and she has been exposed to a herpes zoster rash because she is working as a hospital nurse and has no prior history of chickenpox.
The most appropriate next step in this case would be checking for Varicella-Zoster IgG antibodies which assures immunity to varicella infections. If VZV IgG is present no further action is needed, but if VZV IgG antibodies are absent, then she will need Varicella Zoster Immunoglobulins within ten days from the exposure to shingles. -

She wants to know what you recommend to get rid of them.
Which of the following is the best advice you can give to this patient?Your Answer: Tell her that the appearance of these blood vessels is a normal occurrence with pregnancy
Explanation:Vascular spiders or angiomas, are of no clinical significance during pregnancy as these are common findings and are form as a result of hyperestrogenemia associated with normal pregnancies. These angiomas, as they will resolve spontaneously after delivery, does not require any additional workup or treatment.
Reassurance to the patient is all that is required in this case. -

A 27-year-old G1P0 woman who is at 14 weeks of gestation presented to the medical clinic complaining of persistent nausea and vomiting. Upon history taking and interview, she reported that she frequently had poor appetite and felt lethargic. From her pre-pregnancy weight, it was also noted that she had 3% weight loss in difference. Upon further clinical observation, she looked dry, accompanied with coated tongue.
If the diagnosis of “hyperemesis gravidarum” is to be considered, which of the following will most likely confirm that diagnosis?Your Answer: poor appetite
Correct Answer: she looks dry with coated tongue
Explanation:Hyperemesis gravidarum refers to intractable vomiting during pregnancy, leading to weight loss and volume depletion, resulting in ketonuria and/or ketonemia. There is no consensus on specific diagnostic criteria, but it generally refers to the severe end of the spectrum regarding nausea and vomiting in pregnancy.
Hormone changes wherein hCG levels peak during the first trimester corresponds to the typical onset of hyperemesis symptoms. It is well-known that 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.
Hyperemesis gravidarum refers to extreme cases of nausea and vomiting during pregnancy. The criteria for diagnosis include vomiting that causes significant dehydration (as evidenced by ketonuria or electrolyte abnormalities, and the dry with coated tongue) and weight loss (the most commonly cited marker for this is the loss of at least five percent of the patient’s pre-pregnancy weight) in the setting of pregnancy without any other underlying pathological cause for vomiting.

Which ONE among the following factors does not increase the risk for developing postpartum endometritis?
Your Answer: Advanced maternal age
Explanation:The most common clinical findings in a postpartum women with endometritis are postpartum fever, with tachycardia relative to the rise in temperature, midline lower abdominal pain and uterine tenderness from the 2nd to 10th day of postpartum.
Most common risk factors for the development of postpartum endometritis are:
– Cesarean deliveries are considered as the most important risk factor for postpartum endometritis, especially those performed after the onset of labour.
– Young maternal age.
– Multiple digital cervical examinations.
– Prolonged rupture of membranes.
– Retention of placental products.
– Prolonged labour.
– Chorioamnionitis.

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: Acute endometritis.
Correct 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.

Among the following which is incorrect regarding hypothyroidism in pregnancy?
Your Answer: Thyroxine requirement does not increase in pregnancy and maintenance dose must be continued
Explanation:Thyroxine requirement during pregnancy will increases by 25 to 30 percent, which is seen as early as fifth week of pregnancy.
Children born to those women whose hypothyroidism was inadequately treated during pregnancy, are at higher risk for developing neuropsychiatric impairments.
When a woman who is on thyroxine is planning to conceive, they are advised to increase their thyroxine dose by 30 percent at the time of confirmation of pregnancy.
During pregnancy TSH also should be monitored at every 8 to 10 weeks, with necessary dose adjustments.
Dose requirements of thyroxine will return to pre-pregnancy level soon after delivery and it will not change according to whether the mother is breastfeeding or not.

A 28-year-old woman (gravida 3, para 2) is admitted to hospital at 33 weeks of gestation for an antepartum haemorrhage of 300mL. The bleeding has now stopped. She had a Papanicolaou (Pap) smear done five years ago which was normal. Vital signs are as follows:
Pulse: 76 beats/min
Blood pressure: 120/80 mmHg
Temperature: 36.8°C
Fetal heart rate: 144/min
On physical exam, the uterus is lax and nontender. The fundal height is 34 cm above the pubic symphysis and the presenting part is high and mobile.
Other than fetal monitoring with a cardiotocograph (CTG), which one of the following should be the immediate next step?Your Answer: Ultrasound examination of the uterus.
Explanation:This is a case of a pregnant patient having vaginal bleeding. Given the patient’s presentation, the most likely cause of this patient’s antepartum haemorrhage is placenta praevia. The haemorrhage is unlikely to be due to a vasa praevia because a loss of 300mL would usually cause fetal distress or death, neither of which has occurred. Cervical malignancy is also unlikely as it typically would not have bleeding of this magnitude. A possible diagnosis would be a small placental abruption as it would fit with the lack of uterine tenderness and normal uterine size.
For the immediate management of this patient, induction of labour is contraindicated before the placental site has been confirmed. Also, induction should not be performed when the gestation is only at 33 weeks, especially after an episode of a small antepartum haemorrhage. An ultrasound examination of the uterus is appropriate as it would define whether a placenta praevia is present and its grade. It would also show whether there is any evidence of an intrauterine clot associated with placental abruption from a normally situated placenta.
If a placenta praevia is diagnosed by ultrasound, a pelvic examination under anaesthesia may be a part of the subsequent care, if it is felt that vaginal delivery might be possible. Usually it would be possible if the placenta praevia is grade 1 or grade 2 anterior in type. However, pelvic exam at this stage is certainly not the next step in care, and is rarely used in current clinical care.
A Papanicolaou (Pap) smear will be necessary at some time in the near future, but would not be helpful in the care of this patient currently.
Immediate Caesarean section is not needed as the bleeding has stopped, the foetus is not in distress, and the gestation is only 33 weeks.

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: Most of neonates with neonatal herpes present with mucocutaneous lesions
Correct 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.

Relationship of the long axis of the mother to the long axis of foetus is known as:
Your Answer: Lie
Explanation:Fetal lie refers to the relationship between the long axis of the foetus relative to the long axis of the mother. If the foetus and maternal column are parallel (on the same long axis), the lie is termed vertical or longitudinal lie.
Fetal presentation means, the part of the foetus which is overlying the maternal pelvic inlet.
Position is the positioning of the body of a prenatal foetus in the uterus. It will change as the foetus develops. This is a description of the relation of the presenting part of the foetus to the maternal pelvis. In the case of a longitudinal lie with a vertex presentation, the occiput of the fetal calvarium is the landmark used to describe the position. When the occiput is facing the maternal pubic symphysis, the position is termed direct occiput anterior.
Fetal attitude is defined as the relation of the various parts of the foetus to each other. In the normal attitude, the foetus is in universal flexion. The anatomic explanation for this posture is that it enables the foetus to occupy the least amount of space in the intrauterine cavity. The fetal attitude is extremely difficult, if not impossible, to assess without the help of an ultrasound examination.

Question 25
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). -

In twin deliveries: Which is true?
Your Answer: There is increased risk of postpartum haemorrhage
Explanation:Twin gestations are at increased risk for postpartum haemorrhage (PPH). A number of maternal and peripartum factors are associated with PPH requiring blood transfusion in twin gestations. Reducing the rate of caesarean delivery in twin pregnancies may decrease maternal hemorrhagic morbidity.

Which of the following procedures allow the earliest retrieval of DNA for prenatal diagnosis in pregnancy:
Your Answer: Amniocentesis
Correct 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.

Question 28

A 27-year-old pregnant woman visits to you at 17 weeks of gestation with complaint of eruption or rash, followed by a 2-day history of malaise, low grade fever and rhinorrhea. You suspect measles and order serology tests for her.
Serology report shows that lgM against measles is positive with a negative lgG.
Among the following which is the most appropriate next step in management of this case?Your Answer: Contact tracing
Explanation:The given case scenario describes a typical case of measles in a pregnant woman, which is confirmed by serologic studies. Positive lgM in serology is suggestive of acute infection, while a negative lgG confirms that the infection is in early phase without any seroconversion.
Conservative management of the symptoms and its potential complications is the only management plan therapeutically available after contracting measles. ‘Notification’ and contact tracing are the other very important issues to be considered.
Measles is a notifiable disease and healthcare professionals are mandated on reporting all the identified cases of measles to the authorized public health units. The main objective of this notification is to conduct a contact tracing.MMR vaccine is not useful once measles is contracted, as the vaccine is used for prevention of measles and as prophylaxis in post-exposure cases. For those with contact to a case of measles, MMR vaccine within 72 hours of contact may have a protective effect, but all measles-containing vaccines like MMR and MM RV are contraindicated throughout pregnancy even as prophylaxis.
As the circulating maternal antibodies will cross placenta and enters into the fetal circulation, a positive test does not confirm infection in the fetus. So serologic testing of the fetus is not useful.
NHIG is not useful in treating an established case of measles, as it is used as a post-measles exposure prophylactic for patients such as pregnant women, premature babies, etc who are contraindicated to MMR vaccine.
As both symptoms and lgM levels indicate measles infection, repeating measles-specific serologic test is not useful in this case. In general no test is indicated, unless its result has an impact on the further management of the case or any prognostic value.

Question 29
Correct

A 29-year-old nulliparous woman is admitted to the hospital at 37 weeks of gestation after losing about 200 mL of blood per vagina after having sexual intercourse. The bleeding has now ceased and her vitals are below:
Pulse rate: 64 beats/min
Blood pressure: 120/80 mmHg
Temperature: 36.8°C
On physical exam, the uterus is enlarged and is 37 cm above the pubic symphysis. The uterus is lax and non-tender. On ultrasound, the fetal presentation is cephalic with the head freely mobile above the pelvic brim. The fetal heart rate assessed by auscultation is 155 beats/min.
Which of the following is the most likely of bleeding in this patient?Your Answer: Placenta praevia.
Explanation:In this pregnant patient with an antepartum haemorrhage at 37 weeks of gestation, her clinical presentation points to a placenta previa. Her bleeding has stopped, the uterus is of the expected size and non-tender, and the fetal head is still mobile above the pelvic brim which are all findings that would be consistent with a placenta praevia. An ultrasound examination would be done to rule-out or diagnose the condition.
An Apt test on the blood is necessary to ensure that this is not fetal blood that would come from a ruptured vasa praevia. Although this diagnosis would be unlikely since the bleeding has stopped. If there was a vasa praevia, there would be fetal tachycardia or bradycardia, where a tachycardia is often seen first but then bradycardia takes over late as fetal exsanguination occurs.
In a placental abruption with concealment of blood loss, the uterus would be larger and some uterine tenderness would be found on exam.
A cervical polyp could bleed after sexual intercourse and a speculum examination would be done to exclude it. However, it would be unlikely for a cervical polyp to cause such a large amount of blood loss. A heavy show would also rarely have as heavy as a loss of 200mL.

Question 30
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.

Question 32
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 32-year-old woman who is multigravida and with breech presentation presented to the emergency department for vaginal delivery. Upon spontaneous rupture of the membranes, bradycardia and variable deceleration was noted on the fetal heart rate monitoring.
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 with histories of obesity and type 2 diabetes Mellitus comes to you for advice as she is planning to conceive in next three months. Her blood sugar levels are under control with a HBA1C value of 6%.
Among the following which is an essential supplement for her?Your Answer: Folic acid
Explanation:Patient mentioned above is a known case of type 2 diabetes which makes her at high risk of having neural tube defects. She should be advised to start taking a high dose of (5mg) folic acid supplement daily for at least 1-month prior to conception and it should be continued upto 12 weeks of her pregnancy.
Folate, which is a water-soluble B vitamin, is usually obtained from diet or through supplementation. For those patients with a history of type 2 diabetes mellitus, who are planning for pregnancy, high doses are recommended to prevent any possible neural tube defects.
Vitamin A is not safe and should be avoided in pregnancy due to chances for toxicity.
Vitamin C and iron are not considered as essential vitamins to be taken during pregnancy.

A 37-year-old woman is planning to conceive this year. Upon history-taking and interview, it was noted that she was a regular alcohol drinker and has been using contraceptive pills for the past 3 years.
Which of the following is considered to be the most appropriate advice for the patient?Your Answer: Stop alcohol now
Explanation:Alcohol exposure during pregnancy results in impaired growth, stillbirth, and fetal alcohol spectrum disorder. Fetal alcohol deficits are lifelong issues with no current treatment or established diagnostic or therapeutic tools to prevent and/or ameliorate some of these adverse outcomes.
Alcohol readily crosses the placenta with fetal blood alcohol levels approaching maternal levels within 2 hours of maternal intake. As there is known safe level of alcohol consumption during pregnancy, and alcohol is a known teratogen that can impact fetal growth and development during all stages of pregnancy, the current recommendation from the American College of Obstetricians and Gynaecologists, Centre for Disease Control (CDC), Surgeon General, and medical societies from other countries including the Society of Obstetricians and Gynaecologists of Canada all recommend complete abstinence during pregnancy.

A 23-year-old gravida 1 para 0 at 36 weeks gestation presents to the office complaining of ankle swelling and occasional headache for the past 2 days. She denies any abdominal pain or visual disturbances. On examination you note a fundal height of 35 cm, a fetal heart rate of 140 beats/min, 2+ lower extremity oedema, and a blood pressure of 144/92 mm Hg. A urine dipstick shows 1+ proteinuria.
Which one of the following is the most appropriate next step in the management of this patient?Your Answer: Laboratory evaluation, fetal testing, and 24-hour urine for total protein
Explanation:This patient most likely has preeclampsia, which is defined as an elevated blood pressure and proteinuria after 20 weeks gestation. The patient needs further evaluation, including a 24-hour urine for quantitative measurement of protein, blood pressure monitoring, and laboratory evaluation that includes haemoglobin, haematocrit, a platelet count, and serum levels of transaminase, creatinine, albumin, LDH, and uric acid- A peripheral smear and coagulation profiles also may be obtained- Antepartum fetal testing, such as a nonstress test to assess fetal well-being, would also be appropriate.
→ Ultrasonography should be done to assess for fetal intrauterine growth restriction, but only after an initial laboratory and fetal evaluation.
→ It is not necessary to start this patient on antihypertensive therapy at this point. An obstetric consultation should be considered for patients with preeclampsia.
→ Delivery is the definitive treatment for preeclampsia- The timing of delivery is determined by the gestational age of the foetus and the severity of preeclampsia in the mother. Vaginal delivery is preferred over caesarean delivery, if possible, in patients with preeclampsia. -

One week after the delivery of her baby at the 38th week of pregnancy, a 33-year-old woman developed deep vein thrombosis (DVT). She has been on enoxaparin therapy for DVT. Upon discharge, there is a plan to start her on warfarin. When this was explained, the patient was reluctant to take warfarin since she thinks it might cause problems to the baby because she is planning to breastfeed.
Which of the following is considered correct regarding warfarin and breastfeeding?Your Answer: She should continue to breastfeed her baby while she is on warfarin
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.

Which of the following is correct in the treatment of a case of threatened abortion:
Your Answer: Bed rest
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.

A 32-year-old woman came to your clinic in a small rural town of New South Wales. She is 34 weeks pregnant and all her past 3 pregnancy has been uncomplicated.
On examination her blood pressure is 140/95 mm of Hg today which is higher than her usual blood pressure of 110/70 mmHg. Urinalysis shows protein 2+ and the patient feels well generally.
Among the following, which is the most appropriate next step in management of this patient?Your Answer: Arrange 24-hour ambulatory blood pressure monitoring
Correct 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.
Labetalol though is safe in pregnancy and is considered as an option to treat hypertension, it could be given in the emergency department.

A 27-year-old woman who is 18 weeks pregnant presented to the emergency department due to a sudden onset of dyspnoea and pleuritic chest pain. She is known to have a previous history of deep venous thrombosis (DVT).
Which of the following is considered to be the most appropriate examination for this patient?Your Answer: Ventilation/perfusion scan
Explanation:Pulmonary embolism (PE) is a treatable disease caused by thrombus formation in the lung-vasculature, commonly from the lower extremity’s deep veins compromising the blood flow to the lungs.
Computed tomography of pulmonary arteries (CTPA) and ventilation-perfusion (V/Q) scan are the two most common and widely practiced testing modalities to diagnose pulmonary embolism.Pulmonary ventilation (V) and Perfusion (Q) scan, also known as lung V/Q scan, is a nuclear test that uses the perfusion scan to delineate the blood flow distribution and ventilation scan to measure airflow distribution in the lungs. The primary utilization of the V/Q scan is to help diagnose lung clots called pulmonary embolism. V/Q scan provides help in clinical decision-making by evaluating scans showing ventilation and perfusion in all areas of the lungs using radioactive tracers.
Ventilation-perfusion V/Q scanning is mostly indicated for a patient population in whom CTPA is contraindicated (pregnancy, renal insufficiency CKD stage 4 or more, or severe contrast allergy) or relatively inconclusive.

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:
Correct 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.

A 25-year-old lady is somewhat jaundiced, has black urine, and has pruritus of her abdomen skin at 30 weeks of pregnancy in her first pregnancy. Her blood pressure is 130/80 mmHg, her fundal height is 29 cm above the pubic symphysis, and her liquid volume is a little lower than expected. Laboratory investigations reveal:
Serum bilirubin (unconjugated): 5 mmol/L (0-10)
Serum bilirubin (conjugated): 12 mmol/L (0-5)
Serum alkaline phosphatase (ALP): 450U/L (30--350)
Serum alanine aminotransferase (ALT) 45U/L (<55)
Serum bile acids: 100 mmol/L (1-26)
The most likely cause for her presentation is?Your Answer:
Correct Answer: Obstetric cholestasis.
Explanation:The correct answer is Obstetric Cholestasis.
The characteristics (elevated bile acids, conjugated bilirubin, and alkaline phosphatase (ALP) levels) are typical with obstetric cholestasis, which affects roughly 3-4 percent of pregnant women in Australia. Obstetric cholestasis is diagnosed when otherwise unexplained pruritus occurs in pregnancy and abnormal liver function tests (LFTs) and/or raised bile acids occur in the pregnant woman and both resolve after delivery. Pruritus that involves the palms and soles of the feet is particularly suggestive.
Liver function tests and bile acid levels measurements are used to validate this diagnosis.
All of the other diagnoses are theoretically possible, but unlikely.
On liver function tests, hepatitis A and acute fatty liver of pregnancy (which is frequently associated with severe vomiting in late pregnancy) usually show substantially worse hepatocellular damage.
Pre-eclampsia is connected with hypertension and proteinuria (along with changes in renal function and, in certain cases, thrombocytopenia), while cholelithiasis is associated with obstructive jaundice and pale stools due to a stone in the CBD. -

A 31-year-old woman presented with abdominal pain and vaginal bleeding of around 600 ml at 40 weeks of gestation.
On examination, her vital signs were found to be stable, with a tender abdomen and there were no fetal heart sounds heard on auscultation.
Which among the following is considered the most appropriate next step?Your Answer:
Correct Answer: Amniotomy
Explanation:Placental abruption is commonly defined as the premature separation of the placenta, which complicates approximately 1% of births. During the second half of pregnancy abruption is considered an important cause for vaginal bleeding and is mostly associated with significant perinatal mortality and morbidity.
Clinical presentation of abruption varies from asymptomatic cases to those complicated with fetal death and severe maternal morbidity. Classical symptoms of placental abruption are vaginal bleeding and abdominal pain, but at times severe cases might occur with neither or just of one of these signs. In some cases the amount of vaginal bleeding may not correlates with the degree of abruption, this is because the severity of symptoms is always depend on the location of abruption, whether it is revealed or concealed and the degree of abruption.
Diagnosis of abruption is clinical and the condition should be suspected in every women who presents with vaginal bleeding, abdominal pain or both, with a history of trauma, and in those women who present with an unexplained preterm labor. All causes of abdominal pain and bleeding, like placenta previa, appendicitis, urinary tract infections, preterm labor, fibroid degeneration, ovarian pathology and muscular pain are considered as differential diagnosis of abruption.In the given case patient has developed signs and symptoms of placental abruption, like severe vaginal bleeding with abdominal pain, whose management depends on its presentation, gestational age and the degree of maternal and fetal compromise. As the presentation is widely variable, it is important to individualize the management on a case-by-case basis. More aggressive management is desirable in cases of severe abruption, which is not appropriate in milder cases of abruption. In cases of severe abruption with fetal death, as seen in the given case, it is reasonable to allow the patient to have a vaginal delivery,regardless of gestational age, as long as the mother is stable and there are no other contraindications.
The uterus is contracting vigorously, and labor occurs rapidly and progresses, so amniotomy is mostly sufficient to speed up delivery. There is a significant risk for coagulopathy and hypovolemic shock so intravenous access should be established with aggressive replacement of blood and coagulation factors. Meticulous attention should be paid to the amount of blood loss; general investigations like complete blood count, coagulation studies and type and crossmatch should be done and the blood bank should be informed of the potential for coagulopathy. A Foley catheter should be placed and an hourly urine output should be monitored.
It is prudent to involve an anesthesiologist in the patient’s care, because if labor does not progress rapidly as in cases like feto-pelvic disproportion, fetal malpresentation, or a prior classical cesarean delivery, it will be necessary to conduct a cesarean delivery to avoid worsening of the coagulopathy.
Bleeding from surgical incisions in the presence of DIC may be difficult to control, and it is equally important to stabilize the patient and to correct any coagulation derangement occuring during surgery. The patient should be monitored closely after delivery, with particular attention paid to her vital signs, amount of blood loss, and urine output. In addition, the uterus should be observed closely to ensure that it remains contracted and is not increasing in size.
Immediate delivery is indicated in cases of abruption at term or near term with a live fetus. In such cases the main question is whether vaginal delivery can be achieved without fetal or maternal death or severe morbidity. In cases where there is evidence of fetal compromise, delivery is not imminent and cesarean delivery should be performed promptly, because total placental detachment could occur without warning. -

A 6-year-old girl is brought to the emergency department for evaluation of vaginal discharge. She has had malodorous vaginal discharge and small amounts of vaginal bleeding for about a week. Her mother called the patient’s primary care provider and instructed to stop giving bubble baths to the child, however, the symptoms have not improved. Aside from the discharge, the girl is normal, she was toilet trained at age 2 and has had no episodes of incontinence. She started kindergarten a month ago. Mother informed that patient has no fever, abdominal pain, or dysuria.
On examination, the labia appear normal but a purulent, malodorous vaginal discharge is noted. Visual inspection with the child in knee-chest position shows a whitish foreign body inside the vaginal introitus.
Which among the following is the best next step in management of this patient?Your Answer:
Correct Answer: Irrigate with warmed fluid after local anesthetic application
Explanation:Vaginal spotting, malodorous vaginal discharge and no signs of trauma like lacerations are the clinical features of vaginal foreign bodies in prepubertal girls. The most common object found as foreign body is toilet paper and its management includes warm irrigation and vaginoscopy under sedation/anesthesia.
Common cause of vulvovaginitis in prepubertal girls are vaginal foreign bodies. Although other objects like small toys, hair bands, etc can be occasionally found, the most common vaginal foreign body is toilet paper. Symptoms like malodorous vaginal discharge, intermittent vaginal bleeding or spotting and urinary symptoms like dysuria are caused due to the chronic irritation caused by the foreign body (the whitish foreign body in this case) on the vaginal tissue.
An external pelvic examination is performed with the girl in a knee-chest or frog-leg position in cases of suspected vaginal foreign body. An attempt at removal, after application of a topical anesthetic in the vaginal introitus, using vaginal irrigation with warm fluid or a swab can be done in case of an easily visualized small foreign body like toilet paper. In cases were the age of the girl or the type of foreign body prohibit adequate clinical evaluation the patient should be sedated or given a general anesthesia for examination using a vaginoscope and the foreign body should be removed.
In cases where child abuse or neglect is suspected Child Protective Services should be contacted. Vaginal or rectal foreign bodies can be the initial presentation of sexual abuse; however in otherwise asymptomatic girls with no behavioral changes, urinary symptoms and vulvar or anal trauma, presence of toilet paper is not of an immediately concerning for abuse.
To evaluate pelvic or ovarian masses CT scan of the abdomen and pelvis can be used; but it is not indicated in evaluation of a vaginal foreign body.
Patients in there prepubertal age have a narrow vaginal introitus and sensitive hymenal tissue due to low estrogen levels, so speculum examinations should not be performed in such patients as it can result in significant discomfort and trauma.
Topical estrogen can be used in the treatment of urethral prolapse, which is a cause of vaginal bleeding in prepubertal girls. This diagnosis is unlikely in this case as those with urethral prolapse will present with a beefy red protrusion at the urethra and not a material in the vagina.
Prepubertal girls with retained toilet paper as a vaginal foreign body will present with symptoms like malodorous vaginal discharge and vaginal spotting secondary to irritation. Initial management is topical anaesthetic application and removal of foreign body either by vaginal irrigation with warm fluid or removal with a swab.

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:
Correct 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.

All of the following are characteristic features of normal labour, except:
Your Answer:
Correct Answer: Moderate bleeding
Explanation:Normal labour is characterized by spontaneous onset, rhythmical uterine contractions along with vertex presentation. Cervical dilatation starts from the 1st stage of labour and intensity of the uterine contractions increases with passing time. Bleeding occurs after the child is expelled and the average loss is about 250-500 ml in a normal vaginal delivery.

A 30-year-old primigravida was admitted to the hospital in active labor. On admission, her cervix was 7 cm dilated and 100% effaced. She received epidural anesthesia and proceeded to complete cervical dilation with fetal head at +3 station within a few hours. Patient who has been pushing for 4 hours is exhausted now and says she cannot feel her contractions, nor knows when to push because of the epidural anesthesia. Patient had no complications during the pregnancy and has no chronic medical conditions.
Estimated fetal weight by Leopold maneuvers is 3.4 kg (7.5 lb), patient's vital signs are normal and fetal heart rate tracing is category 1. Tocodynamometer indicates contractions every 2-3 minutes and a repeat cervical examination shows complete cervical dilation with the fetal head at +3 station, in the left occiput anterior position with no molding or caput.
Among the following, which is considered the best next step in management of this patient?Your Answer:
Correct Answer: Perform vacuum-assisted vaginal delivery
Explanation:The period from attaining a complete cervical dilation of 10 cm to fetal delivery is considered as the second stage of labor. In the given case patient have achieved an excellent fetal descent to +3 due to her average-sized infant of 3.4 kg, suitable pelvis (no fetal molding or caput, suggesting no resistance against the bony maternal pelvis), and a favorable fetal position of left occiput anterior.
But with no further fetal descent the patient fulfills the following criterias suggestive of second-stage arrest like:
≥3 hours of pushing in a primigravida without an epidural or ≥4 hours pushing with an epidural, as in this patient
OR
≥2 hours of pushing in a multigravida without an epidural or ≥3 hours pushing with an epidural.As continued pushing without any effect will lead to complications like postpartum hemorrhage, limiting the chances of spontaneous vaginal delivery, it is better to manage this case by operative vaginal delivery procedures like vacuum-assisted delivery, to expedite delivery. maternal exhaustion, fetal distress, and maternal conditions like hypertrophic cardiomyopathy, in which the Valsalva maneuver is not recommended are the other indications for performing an operative vaginal delivery.
Fundal pressure is the technique were external pressure is applied to the most cephalad portion of the uterus, were the applied force is directed toward the maternal pelvis. The maneuver was not found to be useful in improving the rate of spontaneous vaginal deliveries.
Epidurals will not arrest or affect spontaneous vaginal delivery rates, instead they just lengthen the second stage of labor. Also an appropriate analgesia is a prerequisite to use in operative vaginal delivery.
Manual rotation of an infant to a breech presentation for breech vaginal delivery is called as internal podalic version. It is contraindicated in singleton deliveries due to the high risk associated with breech vaginal delivery in regards to neonatal mortality and morbidity.
The ideal fetal head position in vaginal delivery is occiput anterior (OA) as the flexed head in this provides a smaller diameter and facilitates the cardinal movements of labor. The occiput posterior (OP) position, in contrast to OA, presents with a larger-diameter head due to the deflexed position. So the chance for spontaneous vaginal delivery will be decreased if fetal head is rotated to OP position.
A lack of fetal descent after ≥4 hours of pushing in a primigravida with an epidural (≥3 hours without) or ≥3 hours in a multigravida with an epidural (≥2 hours without) is defined as second stage arrest of labor. The condition is effectively managed with operative vaginal delivery procedures like vacuum-assisted delivery. Other common indications for operative vaginal delivery are maternal exhaustion, fetal distress, and maternal conditions where the Valsalva maneuver is not recommended.

A 34-year old primigravida woman came to you for her first prenatal check-up. She is about 7-8 weeks pregnant and enquiries about antenatal screening tests as she is concerned that her baby might have chromosomal abnormalities.
Among the following results, which would indicate further assessment for trisomy 21?Your Answer:
Correct 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 25-year-old Aboriginal woman at ten weeks of gestation presents with a 2-week history of nausea, vomiting and dizziness. She has not seen any doctor during this illness.
On examination, she is found to be dehydrated, her heart rate is 135 per minute (sinus tachycardia), blood pressure 96/60 mm of Hg with a postural drop of more than 20 mm of Hg systolic pressure and is unable to tolerate both liquids and solids.Urine contains ketones and blood tests are pending.
How will you manage this case?Your Answer:
Correct Answer: Give metoclopramide and intravenous normal saline
Explanation:Analysis of presentation shows the patient has developed hyperemesis gravidarum.
She is in early shock, presented as sinus tachycardia and hypotension, with ketonuria and requires immediate fluid resuscitation and anti-emetics. The first line fluid of choice is administration of normal saline 0.9%, and should avoid giving dextrose containing fluids as they can precipitate encephalopathy and worsens hyponatremia.The most appropriate management of a pregnant patient in this situation is administration of metoclopramide as the first line and Ondansetron as second line antiemetic, which are Australian category A and B1 drugs respectively. The following also should be considered and monitored for:
1. More refractory vomiting.
2. Failure to improve.
3. Recurrent hospital admissions.Steroids like prednisolone are third line medications which are used in resistant cases of hyperemesis gravidarum after proper consultation.

A 29-year-old woman at 28 weeks of pregnancy was diagnosed with gestational diabetes. At a high-risk pregnancy clinic, she was considered to have been managed well until 38 weeks when she delivered a healthy 4-kg baby via vaginal delivery without any complications.
Which of the following is the next step in managing her gestational diabetes?Your Answer:
Correct Answer: 75g oral glucose tolerance test performed 6 to 8 weeks after delivery
Explanation:The Australasian Diabetes in Pregnancy Society recommends a 50 or 75 g glucose challenge at 26–28 weeks in all pregnant women. An OGTT should be performed if the test result is abnormal: 1 hour values after a 50 or 75 g glucose challenge exceeding 7.8 or 8.0 mmol/L respectively.
If a woman has had gestational diabetes, a repeat OGTT is recommended at 6–8 weeks and 12 weeks after delivery. If the results are normal, repeat testing is recommended between 1 and 3 years depending on the clinical circumstances.

A 24-year-old woman comes to your office at 38 weeks of gestation with a urinary dipstick result positive for leukocyte and nitrite. She is otherwise asymptomatic so you send her urine for culture and sensitivity test.
From the options below mentioned, which is the next best management for her?Your Answer:
Correct Answer: Prescribe her with Oral Cephalexin
Explanation:There is an association between 20 to 30% increase in the risk for developing pyelonephritis during later pregnancy and untreated cases of bacteriuria in pregnancy. This is due to the physiological changes occurring to urinary tract during pregnancy, it is also found that untreated bacteriuria can be associated with even preterm birth and low birth weight. Risk of symptomatic urinary tract infection (UTI) during pregnancy can be reduced by antibiotic treatment of asymptomatic bacteriuria
The most common pathogen associated with asymptomatic bacteriuria is Escherichia coli, which accounts to more than 80% of isolates and the second most frequently cultured uropathogen is Staphylococcus saprophyticus. Other Gram-positive cocci, like group B streptococci, are less common. Gram-negative bacteria such as Klebsiella, Proteus or other Enterobacteriaceae are the other organisms involved in asymptomatic bacteriuria.
Although the context patient is asymptomatic, her urine dipstick shows positive nitrite and leukocyte, suggestive of urinary tract infection, so oral antibiotics like cephalexin or nitrofurantoin are advisable. Normally a five day course of oral antibiotic will be sufficient for the treatment of uncomplicated UTI or asymptomatic bacteraemia in pregnant women. As the patient is currently at her 38 weeks of gestation nitrofurantoin is contraindicated so it is best to prescribe her with Oral Cephalexin. This is because nitrofurantoin is associated with an increased risk of neonatal jaundice and haemolytic anaemia, so should not be used close to delivery, that is after 37 weeks of gestation or sooner if early delivery is planned.
Acute pyelonephritis should be treated with Intravenous antibiotic treatment, guided by urine culture and sensitivity reports as soon a available. A course of minimum of 10-14 days with IV + oral antibiotics is recommended as treatment for pyelonephritis, along with an increased fluid intake as intravenous fluids in clinically dehydrated patients. Even though urinary alkalisers are safe in pregnancy, prescription of urinary alkalisers alone is not recommended due to its low effectiveness compared to antibiotics, also as it can result in a loss of treatment efficacy urinary alkalisers should never be used in combination with nitrofurantoin.
At any stage of pregnancy, if Streptococcus agalactiae, a group B streptococcus [GBS], is detected in urine the intrapartum prophylaxis for GBS is usually indicated.

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:
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.

A 25-year-old Aboriginal lady presents to antenatal clinic at 19 weeks of her gestation.
This is considered as the best time for which one of the following?Your Answer:
Correct Answer: Ultrasound
Explanation:Between 18-20 weeks of gestation is the best time to perform an ultrasound for the identification of any physical or anatomical abnormalities including neural tube defects.
Maternal serum screening for Down syndrome is best performed between 15-17 weeks of pregnancy and this screening includes analysis of alpha fetoprotein, estriol, and beta-HCG in maternal blood. Conducting tests on accurate dates is necessary to obtain reliable results.
Amniocentesis which is very accurate for the diagnosis of chromosomal anomalies including Down syndrome, is best performed between 16-18 weeks of gestation and it carries a risk of 1 in 200 for miscarriage. Rh negative women will need Rh D immunoglobulin (anti-D).
Chorionic villus sampling is best performed between 10-12 weeks of gestation and carries a 1 in 100 risk of miscarriage, this test is also very much accurate for diagnosis of chromosomal anomalies. Rh negative women need Rh D immunoglobulin (anti-D).
It is best to perform rubella screen before conception than during pregnancy, this is because rubella vaccine is not recommended to be given to a pregnant mother as its a live vaccine.

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:
Correct 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 Answer: Pregnancy is contraindicated in her condition
Explanation:From the options given, option A is correct as primary pulmonary hypertension is considered a contraindication to pregnancy.
The patient should be educated about the possible risks and increased maternal mortality in such cases. This restriction is due to the fact that symptoms of Pulmonary hypertension gets worse during pregnancy which results in high maternal mortality.
Termination of pregnancy may be advisable in these circumstances mostly to preserve the life of the mother.

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:
Correct 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 24-year-old woman presented to the medical clinic for advice regarding pregnancy. Upon history taking and interview, it was noted that she had a history of valvular heart disease. She has been married to her boyfriend for the last 2 years and she now has plans for pregnancy.
Which of the following can lead to death during pregnancy, if present?Your Answer:
Correct Answer: Mitral stenosis
Explanation:Mitral stenosis is the most common cardiac condition affecting women during pregnancy and is poorly tolerated due to the increased intravascular volume, cardiac output and resting heart rate that predictably occur during pregnancy.
Young women may have asymptomatic mitral valve disease which becomes unmasked during the haemodynamic stress of pregnancy. Rheumatic mitral stenosis is the most common cardiac disease found in women during pregnancy. The typical increased volume and heart rate of pregnancy are not well tolerated in patients with more than mild stenosis. Maternal complications of atrial fibrillation and congestive heart failure can occur, and are increased in patients with poor functional class and severe pulmonary artery hypertension.

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:
Correct 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.

A 29 year old female who is 32 weeks pregnant, has been admitted to hospital with very severe hypertension. This is her second pregnancy. What is the first line of treatment for hypertension whilst pregnant?
Your Answer:
Correct Answer: Methyldopa
Explanation:Atenolol is considered teratogenic and has two main risks: fetal bradycardia and neonatal apnoea. ACE inhibitors and angiotensin II receptor blockers are also known to be teratogenic (even though large-scale studies are difficult to conduct during pregnancies).
Non-severe Hypertension and asymptomatic at ≥ 20w
(BP ≥ 140/90 and < 160/110mmHg)
• Urine dipstick analysis
• Quantify 24hr urine protein excretion/U-PCR
• Start Methyldopa 500mg 8hrly
• Do Hb, Platelet count, s-Cr, AST/ALT, Urine specimen for MC&S
• If gestational hypertension is diagnosed and BP is well controlled, continue antihypertensive therapy and plan delivery at 38 weeks if all remains well in the interimHypertension with symptoms or severe features
• Admit in High care unit and nurse in left lateral
• Insert urinary catheter and IV line
• Administer IV Ringers lactate (total volume of IV fluid administered should not exceed
80mls/hr)
• Start Magnesium Sulphate
• Control BP
• Perform an ultrasound (if indicated) or assess clinically to determine fetal viability,
EFW (Estimated Fetal Weight) and liquor volume and, if possible

A 27-year-old woman presented to the medical clinic for antenatal advice because she plans to get pregnant soon. However, she is worried about how she should change her diet once she becomes pregnant already.
Which of the following is considered the best to give to the patient in addition to giving folic acid?Your Answer:
Correct Answer: Iodine
Explanation:There is evidence that folic acid, iodine and vitamin D are important for reproductive outcomes. Folic acid and iodine supplementation is recommended for women planning to conceive and in pregnancy.
The recommended dose of folic acid for women without special considerations planning to conceive is 400-500 mcg. The recommended dose of folic acid for women with special considerations is 2-5 mg per day.
Women planning a pregnancy, including those with thyroid disease, should take iodine supplements in the dose of 150 mcg per day prior to and during pregnancy.

A 24-year-old primigravida at 16 weeks of gestation, presented with a history of vaginal pressure, vaginal spotting and lower back pain.
Transvaginal ultrasound finding shows cervical shortening to 2 cm, cervical dilation, and protrusion of fetal membranes into the cervical canal.
Which among the following risk factors is not related to the development of this condition?Your Answer:
Correct Answer: Alcohol abuse
Explanation:This woman has developed non-specific symptoms of cervical insufficiency, is a painless dilation of cervix resulting in the delivery of a live fetus during the 2nd trimester or premature delivery.
The following has been identified as the risk factors associated with increased incidence of cervical insufficiency:
– Congenital disorders of collagen synthesis like Ehlers-Danlos syndrome.
– Prior cone biopsies.
– Prior deep cervical lacerations, which is secondary to vaginal or cesarean delivery.
-Müllerian duct defects like bicornuate or septate uterus.
– More than three prior fetal losses during the 2nd trimesterFrom the given options, alcohol abuse is the only one not associated with increased incidence of cervical insufficiency.

A 32-year-old woman visited your clinic at her 30th week of gestation, complaining of left lower limb pain.
The doppler ultrasound findings had confirmed proximal deep vein thrombosis and she was treated with low molecular weight heparin.
Now she is at her 34 weeks of gestation, and is expecting delivery in next four weeks. What would be your advice for her today?Your Answer:
Correct Answer: Low molecular weight heparin should be switched to unfractionated heparin
Explanation:This patient has developed deep vein thrombosis during pregnancy and required anti-coagulation as part of treatment for up to 3-6 months. Enoxaparin, which is a low molecular weight heparin, is preferred over heparin due to the once or twice a day therapeutic dosing. Also monitoring of aPTT is not required in this case.
There is an association between Enoxaparin and an increased risk for epidural hematoma in women receiving epidural anaesthesia during labour. Considering that the patient mentioned is expected to go for delivery in 4 weeks and the possibility of her needing an epidural anaesthesia or general anaesthesia in case of undergoing a cesarean section, enoxaparin should be switched to unfractionated heparin, four weeks prior to the anticipated delivery. This is because of the fact that heparin can be antidoted with protamine sulphate.

A 26-year-old woman with irregular menstrual cycle has a positive pregnancy test. She wants to know the age of her baby.
Which of the following methods is considered the most accurate for estimating gestational age?Your Answer:
Correct Answer: Transvaginal ultrasound at 8 weeks
Explanation:Ultrasound has emerged as the more accurate method of assessing fetal gestational age, especially in the first trimester. Both transvaginal and transabdominal probe assessments are used to obtain a more accurate measurement of gestational age. Transvaginal is more helpful in first trimester pregnancies.
A transvaginal ultrasound exam should not be performed in a pregnant patient with vaginal bleeding and known placenta previa, a pregnant patient with premature rupture of membranes, and a patient who refuses exam despite informed discussion.
Sonographic assessment within the first 13 weeks and 6 days will provide the most accurate estimate of gestational age. Both transvaginal and transabdominal approaches may be used. However, the transvaginal approach may provide a more clear and accurate view of early embryonic structures. Although the gestational sac and yolk sac are the first measurable markers visible on ultrasound, these poorly correlate with gestational age.

Consider you are looking after a male baby in neonatal unit. Case chart shows that his mother has been abusing intravenous drugs until late this pregnancy.
You will not discharge this baby home after delivery in all of the following conditions except?Your Answer:
Correct Answer: Weight loss greater than two percent of birth weight
Explanation:If a mother has been abusing drugs during antenatal period, there are some contraindications to discharge her baby home. These conditions includes:
– excessive weight loss, which is greater than ten percent of birth weigh
– suspected baby neglect or abuse
– suspected domestic violence
– a court order preventing baby from being discharged home or if there is requirement for further assessment of withdrawal symptoms.A 2-3 percentages weight loss during the early neonatal period is considered to be a normal finding and is therefore not considered as a contraindication to discharge the baby home.

A 23-year-old woman at 36 weeks of gestation visits your clinic for follow up.
On pelvic ultrasound you noted a decrease in amniotic fluid, and all her previous scans were normal.
When asked she recollected on experiencing an episode of urinary incontinence yesterday, were she had wet her undergarment with a sudden gush of clear fluid.
Considering the presentation, which of the following is MOST likely the cause of oligohydramnios in this patient?Your Answer:
Correct Answer: Premature preterm rupture of membrane
Explanation:This patient presenting with oligohydramnios in her third trimester and had reported an episode of sudden gush of fluid secondary to ruptured membrane which she had mistaken to be “urinary incontinence”. Hence, the most likely cause of oligohydramnios in this patient will be premature preterm rupture of membrane (PPROM).
An amniotic fluid volume which is less than expected for gestational age is called as Oligohydramnios and is typically diagnosed by ultrasound examination. This condition can be qualitatively described as reduced amniotic fluid volume and quantitatively as amniotic fluid index ≤5 cm or a single deepest pocket <2 cm. Oligohydramnios either can be idiopathic or may have a maternal, fetal or placental cause. Fetal prognosis in this case depends on several factors like the underlying cause, the severity of loss ie. reduced versus no amniotic fluid state and the gestational age at which oligohydramnios occurred. As an adequate volume of amniotic fluid is critical for the normal fetal movements, for fetal lung development and for cushioning the fetus and umbilical cord from uterine compression, so pregnancies complicated with oligohydramnios are at higher risk for fetal deformation, pulmonary hypoplasia and umbilical cord compression.
Oligohydramnios is also associated with an increased risk for fetal or neonatal death, which can either be related to the underlying cause of reduction in amniotic fluid volume or due to the sequelae caused due to reduced amniotic fluid volume. The amniotic fluid volume reflects the balance between fluid production and movement of fluid out of the amniotic sac and the most common mechanisms behind oligohydramnios are fetal oliguria/anuria or fluid loss due to rupture of membranes; also reduction in the amount of lung fluid or increased swallowing do not play major roles in this. Idiopathic cases as in idiopathic oligohydramnios, may be due to alterations in the expression of water pores like aquaporin 1 and aquaporin 3, present in fetal membranes and placenta.Causes of oligohydramnios
a) Maternal causes includes:
– Medical or obstetric conditions associated with uteroplacental insufficiency like preeclampsia, chronic hypertension, collagen vascular disease, nephropathy, thrombophilia.
– Intake of medications like angiotensin converting enzyme inhibitors, prostaglandin synthetase inhibitors, trastuzumab.
b) Placental causes are:
– Abruption of placenta
– Twin polyhydramnios-oligohydramnios sequence which is the Twin to twin transfusion
– Placental thrombosis or infarction
c) Fetal cases leading to oligohydramnios are:
– Chromosomal abnormalities
– Congenital abnormalities which are associated with impaired urine production
– Growth restriction
– Demise
– Post-term pregnancy
– Ruptured fetal membranes
– Infections
– Idiopathic causesDuring First trimester: Etiology of oligohydramnios during the first trimester is often unclear. As the gestational sac fluid is primarily derived from the fetal surface of the placenta via transamniotic flow from the maternal compartment and secretions from the surface of the body of the embryo reduced amniotic fluid prior to 10 weeks of gestation is rare.
During Second trimester: Fetal urine begins to enter the amniotic sac and fetus begins to swallow amniotic fluid by the beginning of second trimester, therefore, during this period any disorders related to the renal/urinary system of the fetus begins to play a prominent role in the etiology of oligohydramnios. Some of such anomalies include intrinsic renal disorders like cystic renal disease and obstructive lesions of the lower urinary tract like posterior urethral valves or urethral atresia. Other common causes of oligohydramnios in the second trimester are maternal and placental factors and traumatic or nontraumatic rupture of the fetal membranes.
During Third trimester: Oligohydramnios which is first diagnosed in the third trimester is often associated with PPROM or with conditions such as preeclampsia or other maternal vascular diseases leading to uteroplacental insufficiency. Oligohydramnios frequently accompanies fetal growth restriction as a result of uteroplacental insufficiency.

The major cause of the increased risk of morbidity & mortality among twin gestation is:
Your Answer:
Correct Answer: Preterm delivery
Explanation:Twin pregnancy is associated with a number of obstetric complications, some of them with serious perinatal consequences, especially for the second twin. The rate of perinatal mortality can be up to six times higher in twin compared to singleton pregnancies, largely due to higher rates of preterm delivery and fetal growth restriction seen in twin pregnancies. Preterm birth and birth weight are also significant determinants of morbidity and mortality into infancy and childhood. More than 50% of twins and almost all triplets are born before 37 weeks of gestation and about 15–20% of admissions to neonatal units are associated with preterm twins and triplets.

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:
Correct 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. -

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.

A 31-year-old woman at her 18th week of pregnancy presented to the emergency department with complaints of fishy, thin, white homogeneous vaginal discharge accompanied with an offensive odour. The presence of clue cells was noted during a microscopic test on the discharge.
All of the following statements are considered false regarding her condition, except:Your Answer:
Correct Answer: Relapse rate > 50 percent within 3 months
Explanation:Bacterial vaginosis (BV) affects women of reproductive age and can either be symptomatic or asymptomatic. Bacterial vaginosis is a condition caused by an overgrowth of normal vaginal flora. Most commonly, this presents clinically with increased vaginal discharge that has a fish-like odour. The discharge itself is typically thin and either grey or white.
Although bacterial vaginosis is not considered a sexually transmitted infection, women have an increased risk of acquiring other sexually transmitted infections (STI), and pregnant women have an increased risk of early delivery.
Though effective treatment options do exist, metronidazole or clindamycin, these methods have proven not to be effective long term.
BV recurrence rates are high, approximately 80% three months after effective treatment.

A 29-year-old woman presents to the emergency department of your hospital complaining of fever, she had given birth to a healthy male baby four days ago. 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:
Correct 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.

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:
Correct 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. -

The most common cause of perinatal death in mono-amniotic twin is:
Your Answer:
Correct Answer: Cord entrapment
Explanation:Cord entanglement, a condition unique to MoMo pregnancies, occurs in 42 to 80% of the cases and it has been traditionally related to high perinatal mortality. Umbilical cord entanglement is present in all monoamniotic twins when it is systematically evaluated by ultrasound and colour Doppler. Perinatal mortality in monoamniotic twins is mainly a consequence of conjoined twins, twin reversed arterial perfusion (TRAP), discordant anomaly and spontaneous miscarriage before 20 weeks’ gestation. Expectantly managed monoamniotic twins after 20 weeks have a very good prognosis despite the finding of cord entanglement. The practice of elective very preterm delivery or other interventions to prevent cord accidents in monoamniotic twins should be re-evaluated.

A 30 year old female with a history of two first trimester miscarriages presented at 9 weeks of gestation with per vaginal bleeding. Which of the following is the most appropriate management?
Your Answer:
Correct Answer: Aspirin
Explanation:Antiphospholipid syndrome is the most important treatable cause of recurrent miscarriage. The mechanisms by which antiphospholipid antibodies cause pregnancy morbidity include inhibition of trophoblastic function and differentiation, activation of complement pathways at the maternal–fetal interface, resulting in a local inflammatory response and, in later pregnancy, thrombosis of the uteroplacental vasculature. This patient should be offered referral to a specialist clinic as she has had recurrent miscarriages. Low dose aspirin is one of the treatment options to prevent further miscarriage for patients with antiphospholipid syndrome.

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:
Correct 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. -

A 28-year-old woman at 35 weeks gestation who is gravida 2 para 1, presented to the labour and delivery department since she has been having regular, painful contractions over the past 3 hours. Upon interview and history-taking, it was noted that the patient has had no prenatal care during this pregnancy. She also has no chronic medical conditions, and her only surgery was a low transverse caesarean delivery 2 years ago.
Upon admission, her cervix is 7 cm dilated and 100% effaced with the fetal head at +2 station. Fetal heart rate tracing is category 1.
Administration of epidural analgesia was performed, and the patient was relieved from pain due to the contractions. There was also rupture of membranes which resulted in bright-red amniotic fluid.
Further examination was done and her results were:
Blood pressure is 130/80 mmHg
Pulse is 112/min
Which of the following is most likely considered as the cause of the fetal heart rate tracing?Your Answer:
Correct Answer: Fetal blood loss
Explanation:Fetal heart rate tracings (FHR) under category I include all of the following:
– baseline rate 110– 160 bpm
– baseline FHR variability moderate
– accelerations present or absent
– late or variable decelerations absent
– early decelerations present or absentThe onset of fetal bleeding is marked by a tachycardia followed by a bradycardia with intermittent accelerations or decelerations. Small amounts of vaginal bleeding associated with FHR abnormalities should raise the suspicion of fetal haemorrhage. This condition demands prompt delivery and immediate reexpansion of the neonatal blood volume.

A 24-year-old gravida 3 para 1 is admitted to the hospital at 29 weeks gestation with a high fever, flank pain, and an abnormal urinalysis. You order blood and urine cultures, a CBC, electrolyte levels, and a serum creatinine level. You also start her on intravenous fluids and intravenous cefazolin. After 24 hours of antibiotic treatment she is clinically improved but continues to have fever spikes. What would be the most appropriate management at this time?
Your Answer:
Correct Answer: Continue current management
Explanation:Pyelonephritis is the most common serious medical problem that complicates pregnancy. Infection is more common after midpregnancy, and is usually caused by bacteria ascending from the lower tract. Escheria coli is the offending bacteria in approximately 75% of cases. About 15% of women with acute pyelonephritis are bacteraemia- A common finding is thermoregulatory instability, with very high spiking fevers sometimes followed by hypothermia- Almost 95% of women will be afebrile by 72 hours. However, it is common to see continued fever spikes up until that time- Thus, further evaluation is not indicated unless clinical improvement at 48-71 hours is lacking. If this is the case, the patient should be evaluated for urinary tract obstruction, urinary calculi and an intrarenal or perinephric abscess. Ultrasonography, plain radiography, and modified intravenous pyelography are all acceptable methods, depending on the clinical setting.

A chronic alcoholic lady presented to the medical clinic with complaints of an increase in abdominal size. Ultrasound was performed and revealed a foetus in which parameters correspond to 32 weeks of gestation. Upon history taking, it was noted that she works in a pub and occasionally takes marijuana, cocaine, amphetamine and opioid.
Which of the following is considered to have the most teratogenic effect to the foetus?Your Answer:
Correct Answer: Alcohol
Explanation:All of the conditions that comprise fetal alcohol spectrum disorders stem from one common cause, which is prenatal exposure to alcohol. Alcohol is extremely teratogenic to a foetus. Its effects are wide-ranging and irreversible. Although higher amounts of prenatal alcohol exposure have been linked to increased incidence and severity of fetal alcohol spectrum disorders, there are no studies that demonstrate a safe amount of alcohol that can be consumed during pregnancy. There is also no safe time during pregnancy in which alcohol can be consumed without risk to the foetus. Alcohol is teratogenic during all three trimesters. In summary, any amount of alcohol consumed at any point during pregnancy has the potential cause of irreversible damage that can lead to a fetal alcohol spectrum disorder.
In general, diagnoses within fetal alcohol spectrum disorders have one or more of the following features: abnormal facies, central nervous system abnormalities, and growth retardation.

A 50-year-old woman presents with moderately severe pain in her left groin and thigh. She had recently travelled by airplane from overseas and is at 18 weeks of gestation of her second pregnancy. The only incidence of trauma she can think of is when she hit her left knee on a table yesterday.
On physical examination, it is found that she has some swelling of her left ankle that is not present on the right side. Her first pregnancy was unremarkable except for development of some symptoms that were believed to be related to pelvic symphyseal separation around 28 weeks of gestation.
Which one of the following is the mostly cause for this patient's pain?Your Answer:
Correct Answer: deep venous Thrombosis (DVT) in her left leg
Explanation:For this pregnant patient who recently travelled overseas most likely has a deep venous thrombosis (DVT). It would also be expected that the patient would have oedema in the symptomatic leg and account for the swelling described.
Though they could cause unilateral leg pain, neither symphyseal separation nor sciatica due to a prolapsed intervertebral disc usually occur as early as 18 weeks of gestation. This patient’s symptoms also do not suggest either diagnosis.
Pain due to trauma would usually be maximal at the site where the trauma took place, which would be in the knee for this patient. Traumatic pain and house cleaning also would not cause the pain described or result in ankle swelling.

All of the following statements is considered incorrect regarding the management of deep vein thrombosis in pregnancy, except:
Your Answer:
Correct Answer: Warfarin therapy is contraindicated throughout pregnancy but safe during breast feeding
Explanation:Anticoagulant therapy is the standard treatment for deep vein thrombosis (DVT) but is mostly used in non-pregnant patients. In pregnancy, unfractionated heparin (UFH) and low molecular weight heparin (LMWH) are commonly used. Warfarin therapy is generally avoided in pregnancy because of its fetal toxicity.
Warfarin is contraindicated during pregnancy, but is safe to use postpartum and is compatible with breastfeeding. Low-molecular-weight heparin has largely replaced unfractionated heparin for prophylaxis and treatment in pregnancy.

The relation of different fetal parts to each other determines?
Your Answer:
Correct Answer: Attitude of the foetus
Explanation:Fetal attitude is defined as the relation of the various parts of the foetus to each other. In the normal attitude, the foetus is in universal flexion. The anatomic explanation for this posture is that it enables the foetus to occupy the least amount of space in the intrauterine cavity. The fetal attitude is extremely difficult, if not impossible, to assess without the help of an ultrasound examination.
Fetal lie refers to the relationship between the long axis of the foetus relative to the long axis of the mother. If the foetus and maternal column are parallel (on the same long axis), the lie is termed vertical or longitudinal lie.
Fetal presentation means, the part of the foetus which is overlying the maternal pelvic inlet.
Position is the positioning of the body of a prenatal foetus in the uterus. It will change as the foetus develops. This is a description of the relation of the presenting part of the foetus to the maternal pelvis. In the case of a longitudinal lie with a vertex presentation, the occiput of the fetal calvarium is the landmark used to describe the position. When the occiput is facing the maternal pubic symphysis, the position is termed direct occiput anterior.

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:
Correct 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.

Regarding threatened abortion:
Your Answer:
Correct Answer: Ultrasound should be done to confirm the diagnosis
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.

A 20-year-old primigravida at her 16 weeks of gestation, presented with the history of lower vaginal pressure, vaginal spotting and lower back pain.
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:
Correct 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.

Question 100
Incorrect

During early pregnancy, a pelvic examination may reveal that one adnexa is slightly enlarged. This is most likely due to:
Your Answer:
Correct Answer: Corpus luteal cyst
Explanation:Adnexa refer to the anatomical area adjacent to the uterus, and contains the fallopian tube, ovary, and associated vessels, ligaments, and connective tissue. The reported incidence of adnexal masses in pregnancy ranges from 1 in 81 to 1 in 8000 pregnancies. Most of these adnexal masses are diagnosed incidentally at the time of dating or first trimester screening ultrasound (USS). Functional cyst is the most common adnexal mass in pregnancy, similar to the nonpregnant state. A corpus luteum persisting into the second trimester accounts for 13-17% of all cystic adnexal masses. Pain due to rupture, haemorrhage into the cyst, infection, venous congestion, or torsion may be of sudden onset or of a more chronic nature.
