What is the next step in management?Your Answer: Primrose oil
Explanation:PMS is a condition, which is associated with somatic, emotional and behavioural symptoms during the women menstruation. Oenothera biennis with the common name of “evening primrose” is containing a valuable fixed oil with commercial name of EPO. Evening primrose oil has two types of omega-6-fatty acid including linoleic acid (60%–80%) and γ-linoleic acid (8%–14%). Essential fatty acids are considered as essential compounds for body health, especially among women. Evening primrose oil’s is effective in women health, but the immediate response should not be expected from it, therefore, it should be regularly used up to 4 or 6 months.
Oral contraceptive pills are only used when other treatments fail.
SSRI are only indicated in cases of persistent mood changes like depression.
Local anaesthetics have no role in the management of PMS. -

A 40 year old women who is 13 weeks pregnant is found to have be high risk for Downs following the combined screening test. What is the most appropriate further test to see if the foetus is affected?
Your Answer: Nuchal thickness imaging
Correct Answer: Chorionic Villous Sampling
Explanation:Chorion villus sampling is an invasive procedure which aims to collect the rapidly dividing cells in the placenta. It is used for numerous reasons including detection of early pregnancy, viability of the foetus, singleton pregnancy, confirm gestation age and for prenatal diagnosis of the fetal chromosomal abnormalities including diagnosis of Down’s syndrome. However it hold a 2% chance of miscarriage during the procedure. Nuchal thickness and imaging are part of the combined test that must have been performed before.

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: 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.

A 27-year-old woman presented to the medical clinic due to infertility. Upon interview, it was noted that she has been having unprotected intercourse with her husband regularly for the past year but has not become pregnant. She mentioned that her last menstrual period was 3 weeks ago. Her menses occur every 28 to 30 days and they last 4 to 5 days. A day before her menses, she has episodes of severe lower abdominal pain that is only partially relieved by ibuprofen.
Further history taking was done and revealed that she was treated for gonococcal cervicitis at age 19. The patient also takes a prenatal vitamin every day and does not use tobacco, alcohol, or illicit drugs. Her 31-year-old husband recently had semen analysis and his results were normal.
Further examination was done and the following are her results:
Blood pressure is 126/70mmHg
Pulse is 85/min
BMI is 31 kg/m2
Upon further examination and observation, it was revealed that she has a small uterus with a cervix that appears laterally displaced and there is accompanying pain upon cervical manipulation.
Which of the following is most likely considered the cause of the patient’s infertility?Your Answer: Submucosal fibroids
Correct Answer: Endometriosis
Explanation:Endometriosis is a chronic gynaecologic disease characterized by the development and presence of histological elements like endometrial glands and stroma in anatomical positions and organs outside of the uterine cavity. The main clinical manifestations of the disease are chronic pelvic pain and impaired fertility. The localization of endometriosis lesions can vary, with the most commonly involved focus of the disease the ovaries followed by the posterior broad ligament, the anterior cul-de-sac, the posterior cul-de-sac, and the uterosacral ligament.
The clinical presentation of the disease differs in women and may be unexpected not only in the presentation but also in the duration. Clinicians usually suspect and are more likely to diagnose the disease in females presenting with the typical symptomatology such as dyspareunia, namely painful sexual intercourse, pelvic pain during menstruation (dysmenorrhea), pain in the urination (dysuria), defecation (dyschezia), and/or infertility. The pain is usually characterized as chronic, cyclic, and progressive (exacerbating over time). Furthermore, some women suffering from endometriosis experience hyperalgesia, a phenomenon, when even with the application of a nonpainful stimulus, an intolerable painful reaction is released. This condition indicates neuropathic pain.
Tenderness on vaginal examination, palpable nodules in the posterior fornix, adnexal masses, and immobility of the uterus are diagnostically indicating findings of endometriosis.

Question 7
Incorrect

Due to her inability to conceive, a 28-year-old nulligravid lady comes to the office with her husband. The patient and her spouse had been having intercourse every other day since they stopped using barrier contraception a year ago. Every 28 days, the patient experiences a 5-day period with two days of high flow. She has transient pelvic pain 14 days after her menstruation begins, but intercourse is painless.
The patient was admitted to the hospital in her late teens for a pelvic infection, and she had discomfort with intercourse, discharge, and fever during her stay. She hasn't had any previous medical or surgical procedures. Her younger sibling suffers from polycystic ovarian syndrome. The patient's husband is 32 years old, has no children, and a normal semen analysis. The patient has a blood pressure of 130/80 mm Hg and a pulse rate of 86 beats per minute. There are no anomalies on physical examination.
Which of the following is the most appropriate next step in this patient's care?Your Answer: Serum FSH level
Correct Answer: Hysterosalpingogram
Explanation:Primary infertility is defined as the inability to conceive after a year of unprotected, timed sexual intercourse in a nulliparous patient under the age of 35. (After 35 years of age, infertility testing can begin after 6 months.) Because the patient’s partner’s sperm analysis is normal, female factor infertility is the most likely explanation. This patient’s adolescent hospitalizations are likely due to pelvic inflammatory disease (PID), a common cause of infertility caused by tubal scarring and blockage.
A hysterosalpingogram, which includes infusing radiocontrast into the cervix under fluoroscopy, is the first-line imaging technique for determining fallopian tube patency. A hysterosalpingogram is a non-invasive procedure that can detect uterine cavity irregularities (e.g., bicornuate uterus).
Peritoneal adhesions and endometriosis can be seen and treated directly using laparoscopy.
PID-related scarring inside the fallopian tubes can be assessed by laparoscopy with chromotubation; however, it is invasive, expensive, and not utilized first-line.
Ovulation is detected using a mid-cycle LH level. The LH surge can be detected in urine and serum 36 hours before ovulation. Regular menstrual periods are characterized by mittelschmerz (mid-cycle pelvic pain), which indicates ovulation. As a result, an LH level would be useless.
Ovarian reserve begins to deteriorate around the age of 35, and serum FSH levels rise in women who are losing their ability to ovulate. Because this patient is much younger and has regular periods, a drop in ovum quantity is unlikely to be the reason for infertility.
Increased serum androgen levels can prevent ovulation by inhibiting the release of GnRH and FSH through feedback inhibition. The patient has regular cycles and no hyperandrogenic symptoms, despite her sister having polycystic ovarian syndrome (e.g., hirsutism, irregular menses).
In a nulliparous patient under the age of 35, primary infertility is defined as the inability to conceive after a year of unprotected sexual intercourse. A hysterosalpingogram is used to determine the cause of infertility, such as tubal blockage caused by a previous pelvic infection.

A 37-year-old woman has been taking Microgynon (oral contraceptive pill [OCP]).
When she presents for a repeat prescription, her BP is 160/100 mmHg.
She mentions that she would like to stop the OCP in six months so that she can conceive.
What is the most suitable advice for this woman?Your Answer: Cease the OCP, use condoms for contraception, and reassess the BP in three months.
Explanation:The woman’s blood pressure was elevated at her visit; therefore she should be advised to immediately cease the oral contraceptive pill (OCP) so that the hypertension can resolve without the need for any hypotensive treatment. The blood pressure can then be reassessed in three months. Alternative, non-hormonal birth control methods such as condoms should be used instead.
If her high blood pressure does not resolve, any medication that would be commenced to reduce her blood pressure should be one that is safe to continue when she becomes pregnant.
It is inappropriate to continue the OCP even at a lower dosage or in combination with a hypotensive agent.
Methyldopa has been evaluated and used for treatment of hypertension during pregnancy. There is no clinical evidence to suggest that it causes harm to the foetus or neonate.
Angiotensin converting enzyme (ACE) inhibitors are not approved for use in pregnancy as they have been associated with fetal death in utero. Other antihypertensive agents such as beta-blockers and diuretics are also problematic in pregnancy and should be avoided.

A 32-year-old woman, gravida 2 para 1, at 40 weeks gestation is admitted to the hospital due to contractions and spontaneous rupture of membranes. Patient underwent a cesarean delivery with her first child due to breech presentation, but this pregnancy has been uncomplicated. She has no chronic medical conditions and is taking only a prenatal vitamin.
Her pre-pregnancy BMI was 20 kg/m2 and she has gained 15.9 kg (35 lb) during pregnancy. On examination her blood pressure is found to be 130/80 mm Hg.
The patient is admitted and epidural anesthesia is administered with an intrauterine pressure catheter in place. She quickly dilates to 10 cm with the fetal vertex at 0 station, occiput transverse. Four hours later, the pelvic examination is unchanged but there is molding and caput on the fetal head. Fetal monitoring is category I. Contractions occur every 2-3 minutes and the patient pushes with each contraction. The contraction strength is an average of 210 MVU every 10 minutes.
Which among the following is most likely the etiology for this patient’s clinical presentation?Your Answer: Fetal malposition
Explanation:Condition where there is insufficient fetal descent after pushing for ≥3 hours in nulliparous and ≥2 hours if multiparous women is defined as Second stage arrest of labor. Common risk factors for this presentation are maternal obesity, excessive weight gain during pregnancy and diabetes mellitus. Cephalopelvic disproportion, malposition, inadequate contractions and maternal exhaustion are the common etiologies of Second stage arrest of labor. Management includes Operative vaginal delivery or cesarean delivery as indicated in the case.
The second stage of labor begins with the dilatation of cervix to 10 cm and will end with fetal delivery. Parity and use of neuraxial anesthesia are the two factors which will affect the duration of second stage of labor and fetal station, which measures the descent of the fetal head through the pelvis determines its progression.
When there is no fetal descent after pushing for ≥3 hours or ≥2 hours in in nulliparous and multiparous patients respectively the condition is called an arrested second stage of labor. As her first delivery was a cesarean session due to breech presentation, this patient in the case is considered as nulliparous.
Most common cause of a protracted or arrested second stage is fetal malposition, which is the relation between the fetal presenting part to the maternal pelvis. Occiput anterior is the optimal fetal position as it facilitates the cardinal movements of labor, any deviations from this position like in occiput transverse position, can lead to cephalopelvic disproportion resulting in second stage arrest.
Inadequate contractions, that is less than 200 MVU averaged over 10 minutes, can lead to labor arrest but contractions are adequate in case of the patient mentioned.
Second stage arrest can be due to maternal obesity and excessive weight gain during pregnancy but this patient had a normal pre-pregnancy BMI of 20 kg/m2 and an appropriate weight gain of 15.9 kg 35 lb. So this also cannot be the reason.Maternal expulsive efforts will change the fetal skull shape. This process called as molding helps to facilitate delivery by changing the fetal head into the shape of the pelvis. Whereas prolonged pressure on head can result in scalp edema which is called as caput, presence of both molding and caput suggest cephalopelvic disproportion, but is not suggestive of poor maternal effort.
Patients with a prior history of uterine myomectomy or cesarean delivery are at higher risk for uterine rupture. In cases of uterine rupture, the patient will present with fetal heart rate abnormalities, sudden loss of fetal station (eg, going from +1 to −3 station) along with fetal retreat upward and into the abdominal cavity through the uterine scar due to decreased intrauterine pressure. In the given case patient’s fetal heart rate tracing is category 1 and fetal station has remained 0 which are non suggestive of uterine rupture.
When there is insufficient fetal descent after pushing ≥3 hours in nulliparous patients or ≥2 hours in multiparous patients is considered as second stage arrest of labor. The most common cause of second stage arrest is cephalopelvic disproportion, were the fetus presents in a nonocciput anterior position called as fetal malposition.

All the following hormones are products of placental synthesis, EXCEPT:
Your Answer: Prolactin
Explanation:The metabolic adaptations of pregnancy are orchestrated by hormones produced by the placenta and maternal pituitary gland, which undergo dramatic changes during gestation. After involution of ovarian sex steroid production by wk 6, placental oestrogen and progesterone production increases exponentially to term. Concurrently, there are progressive increases in prolactin (PRL), produced by the maternal pituitary gland and decidua, and human chorionic somatomammotropin (CSH, also called human placental lactogen), which has structural similarities to GH and PRL.

A 46-year-old woman with regular menstrual cycles presents with a history of menorrhagia for the last 6 years. Her menstrual cycles are normal, but she has bled excessively for eight days every month, and her haemoglobin level was 90g/L one month ago. She's already on iron supplementation. She has a history of cervical intraepithelial neoplasia grade 3 (CIN3) in addition to the anaemia, albeit her yearly smear test has been normal since the laser treatment six years ago. She is also undergoing hypertension treatment. Physical examination is unremarkable. She is not willing for endometrial ablation or hysterectomy until her menopause. Which of the following medical therapies would be the best for her to utilize between now and the time she is expected to hit menopause, which is around the age of 50?
Your Answer: HRT given from the time of menopause at the age of approximately 50 years, reduces the decline of cognitive function, often seen as an early manifestation of AD
Explanation:Adenomyosis or dysfunctional uterine haemorrhage are the most likely causes of heavy periods.
Because she refuses to have a hysterectomy or endometrial ablation, hormonal therapy must be administered in addition to the iron therapy she is already receiving.
Any of the choices could be employed, but using therapy only during the luteal phase of the cycle in someone who is virtually surely ovulating (based on her typical monthly cycles) is unlikely to work.Danazol is prone to cause serious adverse effects (virilization), especially when used for a long period of time.
GnRH agonists would cause amenorrhoea but are more likely to cause substantial menopausal symptoms, and the °fa contraceptive pill (OCP) is generally best avoided in someone using hypertension medication.Treatment with norethisterone throughout the cycle is likely to be the most successful of the treatments available.
If a levonorgestrel-releasing intrauterine device (Mirena®) had been offered as an alternative, it would have been acceptable. -

A 53-year-old lady had mild vaginal bleeding for the previous 18 hours following sexual engagement. It's been a year since she had her last menstrual cycle. Her previous cervical screening test was 12 months ago, and everything came back normal. For the past year, she had not engaged in any sexual activity. She wasn't on any hormone replacement treatment at the time.
Which of the following is the most likely cause of her symptoms?Your Answer: Atrophic vaginitis
Explanation:Postmenopausal haemorrhage has started in this patient. Menopause is defined as the permanent cessation of menstruation and fertility that occurs 12 months after the previous menstrual period.
Atrophic vaginitis caused by oestrogen insufficiency is the most likely reason for this woman’s postmenopausal haemorrhage. It can also induce vaginal dryness and soreness during sexual intercourse.
Endometrial hyperplasia is unlikely to develop without hormone replacement therapy or oestrogen stimulation of the endometrium.
Similarly, endometrial cancer is a less likely cause of this patient’s post-menopausal bleeding.
A year ago, this woman received a normal cervical screening test. Cervical cancer is extremely unlikely to occur. After 12 months of no oestrogen, it’s also unlikely that you’ll have any irregular periods.

Transvaginal ultrasound shows cervical shortening to 2 cm, cervical dilation, and protrusion of fetal membranes into the cervical canal. Findings confirms the woman has developed non-specific symptoms of cervical insufficiency which may lead to premature delivery.
Which among the following is the most appropriate management in this case?Your Answer: Reinforcement of the cervical ring with nonabsorbable suture material
Explanation:Patient mentioned in the given case has developed clinical features of cervical insufficiency and the possible treatment options include:
1- Cerclage, which is the technique used for the reinforcement of cervical ring with nonabsorbable suture material and is indicated based on ultrasonographic findings. It is the treatment of choice when cervical shortening is detected by ultrasonography before 22 to 24 weeks of gestation.2- Vaginal progesterone is used to reduce the risk of preterm delivery in women who have a prior history of idiopathic preterm delivery or cervical shortening, which is confirmed in the current pregnancy also by ultrasonography.This method is applicable only to those women who do not meet the criteria for Cerclage.

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.

You are asked to see a 26 year old patient following her first visit to antenatal clinic. She is 9 weeks pregnant and bloods have shown her to be non-immune to Rubella. She is concerned about congenital rubella syndrome (CRS). What is the most appropriate advice to give?
Your Answer: Advise vaccination after birth regardless of breast feeding status
Explanation:For pregnant women who are screened and rubella antibody is not detected, rubella vaccination after pregnancy should be advised. Vaccination during pregnancy is contraindicated because of a theoretical risk that the vaccine itself could be teratogenic, as it is a live vaccine. No cases of congenital rubella syndrome resulting from vaccination during pregnancy have been reported. However, women who are vaccinated postpartum should be advised to use contraception for three months.

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.

Among the below given options, which is NOT associated with an increased risk for preeclampsia?
Your Answer: Nulliparity
Correct Answer: Age between 18 and 40 years
Explanation:Any new onset of hypertension associated with proteinuria after 20 weeks of gestation in a previously normotensive woman is referred to as Preeclampsia.
Most commonly found risk factors for pre-eclampsia are:
– Preeclampsia in a previous pregnancy
– Family history of preeclampsia
– a prior pregnancy with poor outcome like placental abruption, IUGR, fetal death in utero, etc
– An interdelivery interval greater than 10 years
– Nulliparity, increases risk by 8 times
– Pre-existing chronic medical conditions or chronic hypertension
– pre-existing or gestational Diabetes
– chronic Renal disease
– Thrombophilias g. protein C and S deficiency, antithrombin Ill deficiency, or Factor V Leiden mutation
– Antiphospholipid syndrome
– Systemic lupus erythematous
– Maternal age greater than or equal to 40 years
– Body Mass Index (BMI) greater than 30 kg/m2
– Multiple pregnancy
– Raised blood pressure at booking
– Gestational trophoblastic disease
– Fetal triploidyMaternal age between 18 and 40 years is found to be associated with a decreased risk for developing preeclampsia, and not an increased risk.
NOTE– Previously, age 16 years or younger was thought to be a risk factor for developing preeclampsia; however, recent studies conducted had failed to establish any meaningful relationship between the two. -

Normal physiological gut herniation occurs at how many weeks gestation?
Your Answer: 3 weeks
Correct Answer: 8 weeks
Explanation:At about 8-12 weeks gestation, normal physiological herniation of the fetal bowel occurs. The midgut protrudes into the base of the umbilicus, and undergoes a 90-degree anticlockwise rotation. When the abdominal cavity enlarges enough to fit the developing midgut, the intestines undergo another 180-degree rotation before returning to the abdominal cavity.

At the 18th week of her pregnancy, a 32-year-old woman presents with a fishy-smelling, thin, white homogeneous, and offensive vaginal discharge. Under light microscopy, a sample of the discharge contains clue cells.
Which of the following assertions about this condition is correct?Your Answer: There is a relapse rate of over 50% in 6 months
Explanation:Reported cure rates for an episode of acute BV vary but have been estimated to be between 70% and 80%. Unfortunately, more than 50% of BV cases will recur at least once within the following 12 months. Because the aetiology of BV is still not entirely understood, identifying the cause of recurrent cases is challenging. Reinfection may play a role in explaining recurrent BV, but
treatment failure is a more likely contributor. There are several theories that try to explain recurrence and persistent symptoms. The existence of a biofilm in the vagina is one such theory and is the subject of ongoing research. Biofilms occur when microorganisms adhere to surfaces. G vaginalis, one of the primary organismsBV is not a sexually transmitted infection. The antibiotic of choice to treat BV is Metronidazole. Reassurance is not acceptable as a means of treatment.

A 30 year old women who is 24 weeks pregnant attends EPU due to suprapubic pain. Ultrasound shows a viable foetus and also a fibroid with a cystic fluid filled centre. What is the likely diagnosis?
Your Answer: Cystic degeneration of fibroid
Correct Answer: Red degeneration of fibroid
Explanation:Red degeneration of fibroids is one of 4 methods of fibroid degeneration. Although uncommon outside pregnancy it is thought to be the most common form of fibroid degeneration during pregnancy and typically occurs in the 2nd trimester. It is thought to arise from the fibroid outgrowing its blood supply and haemorrhagic infarction occurs. Ultrasound will typically show a localised fluid collection (blood) within the fibroid.

Jenny, a 23-year-old woman who is at 14 weeks gestation, presented to the medical clinic because she developed a rash characteristic of chickenpox after 2 days of low-grade fever and mild malaise. Serological test was performed and revealed positive anti-varicella lgM.
Which of the following is considered to be the most appropriate course of action for the patient?Your Answer: Repeat serology in one week
Correct Answer: Antiviral therapy and pelvic ultrasound
Explanation:Chickenpox or varicella is a contagious disease caused by the varicella-zoster virus (VZV). The virus is responsible for chickenpox (usually primary infection in non-immune hosts) and herpes zoster or shingles (following reactivation of latent infection). Chickenpox results in a skin rash that forms small, itchy blisters, which scabs over. It typically starts on the chest, back, and face then spreads. It is accompanied by fever, fatigue, pharyngitis, and headaches which usually last five to seven days. Complications include pneumonia, brain inflammation, and bacterial skin infections. The disease is more severe in adults than in children.
Primary varicella infection during pregnancy can also affect the foetus, who may present later with chickenpox. In pregnant women, antibodies produced as a result of immunization or previous infection are transferred via the placenta to the foetus. Varicella infection in pregnant women could spread via the placenta and infect the foetus. If infection occurs during the first 28 weeks of pregnancy, congenital varicella syndrome may develop. Effects on the foetus can include underdeveloped toes and fingers, structural eye damage, neurological disorder, and anal and bladder malformation.
Prenatal diagnosis of fetal varicella can be performed using ultrasound, though a delay of 5 weeks following primary maternal infection is advised.
Antivirals are typically indicated in adults, including pregnant women because this group is more prone to complications.

Which of the following is the most appropriate suggestion for folic acid supplementation?Your Answer: She should be started on folic acid 0.5 mg per day
Explanation:Folate has been in the news because of its connection with a type of birth defect called neural tube defect. Studies have shown that women who have infants with neural tube defects have lower intakes of folate and lower blood folate levels than other women. Folate is needed early in pregnancy (before many women know they are pregnant) for normal neural tube development.
Many vegan foods including enriched bread, pasta, and cold cereal; dried beans; green leafy vegetables; and orange juice are good sources of folate. Vegan diets tend to be high in folate, however, to be on the safe side, women capable of becoming pregnant should take a supplement or use fortified foods that provide 400 micrograms of folate daily.
For the above mentioned reasons, all other options are incorrect.

Among the following which is the most likely finding of placental abruption in a pregnant woman?
Your Answer: Vaginal bleeding
Explanation:Placental abruption is defined as the premature separation of placenta from uterus and the condition usually presents with bleeding, uterine contractions and fetal distress. It is one of the most significant cause of third-trimester bleeding and is often associated with fetal and maternal mortality and morbidity. In all pregnant women with vaginal bleeding in the second half of the pregnancy, this condition should be considered as a differential diagnoses.
Though vaginal bleeding is the most common presenting symptom reported by almost 80% of women with placental abruption, vaginal bleeding is concealed in 20% of women with placental abruption, therefore, absence of vaginal bleeding does not exclude placental abruption.Symptoms and complications of placental abruption varies according to patient, frequency of appearance of some common features is as follows:
- Vaginal bleeding is the common presentation in 80% of patients.
- Abdominal or lower back pain with uterine tenderness is found in 70%
- Fetal distress is seen in 60% of women.
- Abnormal uterine contractions like hypertonic, high frequency contractions are seen in 35% cases.
- Idiopathic premature labor in 25% of patients.
- Fetal death in about 15% of cases.Examination findings include vaginal bleeding, uterine contractions with or without tenderness, shock, absence of fetal heart sounds and increased fundal height due to an expanding hematoma. Shock is seen in class 3 placental abruption which represents almost 24% of all cases of placental abruption.

A 19 year old patient on Lamotrigine 125 mg twice a day for the past two years has recently been prescribed Microgynon 30 as a contraceptive before she leaves for Uni. What could the main concern be?
Your Answer: Combined contraceptive may reduce Lamotrigine levels and increase seizure risk
Explanation:Lamotrigine, a drug used to treat epilepsy, is less effective when taken with combined oral contraceptives. The oestrogen component of the pill decreases the circulating levels of Lamotrigine, increasing the risk of seizures. The combination is therefore classified as a UKMEC 3, as the risk of the drug combination may outweigh the benefit. As an alternative, the progesterone-only pill, depo progesterone, Mirena or the copper IUD may be considered as there is no restriction on concomitant use. Lamotrigine is not metabolised through cytochrome P450 like other antiepileptic drugs such as carbamazepine and phenytoin, neither is it an enzyme inhibitor.

The performance of a cervical cerclage at 14 weeks of gestation is determined by which of the following indications?
Your Answer: 2 or more consecutive prior second trimester pregnancy losses
Explanation:Cervical cerclage is performed as an attempt to prolong pregnancy in certain women who are at higher risk of preterm delivery.
There are three well-accepted indications for cervical cerclage placement. According to the American College of Obstetricians and Gynaecologists (ACOG), a history-indicated or prophylactic cerclage may be placed when there is a “history of one or more second-trimester pregnancy losses related to painless cervical dilation and in the absence of labour or abruptio placentae,” or if the woman had a prior cerclage placed due to cervical insufficiency in the second trimester.
An ultrasound-indicated cerclage may be considered for women who have a history of spontaneous loss or preterm birth at less than 34 weeks gestation if the cervical length in a current singleton pregnancy is noted to be less than 25 mm before 24 weeks of gestation. It is important to note that this recommendation is invalidated without the history of preterm birth.
Physical examination-indicated cerclage (also known as emergency or rescue cerclage) should be considered for patients with a singleton pregnancy at less than 24 weeks gestation with advanced cervical dilation in the absence of contractions, intraamniotic infection or placental abruption.

A 50-year-old menopausal woman complained of regular hot flushes that interfered with her sleep and job. She had a ten-year history of oestrogen-dependent breast cancer.
What is the most effective treatment for her symptoms?Your Answer: Progesterone only
Correct Answer: Paroxetine
Explanation:Paroxetine is an SSRI used for hot flushes in women with contraindication for hormonal therapy.
Hormonal or other pharmacotherapy is usually needed for women with bothersome hot flashes. For most women with moderate to very severe hot flashes and no contraindications, we suggest MHT. Women with an intact uterus need both oestrogen and a progestin, while those who have undergone hysterectomy can receive oestrogen only. For women interested in MHT, the first step is to determine the potential risks for the specific individual.
The majority of perimenopausal and recently menopausal women are good candidates for short-term hormone therapy for symptom relief. However, for women with a history of breast cancer, coronary heart disease (CHD), a previous venous thromboembolic event (VTE) or stroke, or those at moderate or high risk for these complications, alternatives to hormone therapy should be suggested. For women with moderate to severe hot flashes who are not candidates for hormone therapy based upon their breast cancer, CHD, or VTE risk and for those who choose not to take MHT, we suggest nonhormonal agents. The agents most commonly used include SSRIs, serotonin-norepinephrine reuptake inhibitors (SNRIs), antiepileptics, and centrally acting drugs.

A 23-year-old female came to see you because of absent menses for the last 5 months. She reports that in the past, menstrual periods were regular, every 28 days. Her first menstrual periods were at the age of 12. She is sexually active with her boyfriend and they use condoms consistently. She does not use oral contraceptive pills. She eats a healthy diet and does not smoke or drink alcohol.
Physical examination is non-remarkable. Pregnancy test is negative. Which of the following is the most appropriate next step in the evaluation of this patient?Your Answer: Order FSH and LH level
Correct Answer: Order TSH and prolactin level
Explanation:This patient presents with secondary amenorrhea, a condition diagnosed in patients with – 3 months of absence of menstruation when they had regular menstruation previously or absence of menstruation for 9 months in a patient who had oligomenorrhea- This differs from primary amenorrhea, which is defined as absence of menstrual periods in a female by the age 16 when she has other secondary sexual characteristics or absence of menstrual periods by the age of 14 when she does not have any other secondary sexual characteristics.
In female patients of child-bearing age, the initial test in evaluating secondary amenorrhea is the pregnancy test. This test has been done in this patient and it is negative- The next step in evaluation in this patient should be serum TSH and prolactin level measurements. Thyroid disease and pituitary pathologies are some of the most common causes of secondary amenorrhea- If these tests were to be found normal, the progesterone challenge test would be the following test as this allows evaluation whether amenorrhea is due to progesterone deficiency in a patient with normal oestrogen levels.
→ Order FSH and LH level is incorrect. These studies are done if the progesterone withdrawal test is negative but the oestrogen-progesterone challenge test is positive; however, the patient should first have TSH and prolactin level measured; the progesterone withdrawal test is only done if TSH and prolactin are normal.
→ Order a progesterone withdrawal test is incorrect. As explained above, this test is ordered if TSH and prolactin levels are normal in a patient suspected to have secondary amenorrhea.
→ Order pelvic ultrasound is incorrect. This study is more important in primary amenorrhea evaluation as it can help confirm the presence or absence of a uterus. This patient who has had menstrual periods before does certainly have a uterus.
→ Order brain MRI is incorrect. Given how expensive this study is, it should not be done before prolactin levels are found to be significantly high, raising suspicion of a pituitary pathology. -

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: 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. -

After a vaginal delivery, a patient suffers a perineal tear. On examination the laceration involves the external anal sphincter and has partially torn the internal anal sphincter. Which of the following classifies this tear?
Your Answer: 3b
Correct Answer: 3c
Explanation:During childbearing the vagina and perineum are prone to lacerations that may involve the skin or can extend into the anal sphincter complex. It is important to be able to identify obstetric and anal sphincter injuries to provide adequate care and prevent complications. In the classification of obstetric tears according to RCOG guidelines:
First degree tear: injury to the perineal skin and/or the vaginal mucosa
Second degree tears: Injury to perineum involving perineal muscles but not the anal sphincter.
Third-degree tear: Injury to perineum involving the anal sphincter complex:
Grade 3a tear: Less than 50% of external anal sphincter (EAS) thickness torn.
Grade 3b tear: More than 50% of EAS thickness torn.
Grade 3c tear: Both EAS and internal anal sphincter (IAS) torn.
Fourth-degree tear: Injury to perineum involving the anal sphincter complex (EAS and IAS)
and anorectal mucosa. -

A 29-year-old gravida 6, para 5 woman at 36 weeks of gestation arrives in the ED via ambulance and precipitously delivers a male child. The child coughs and has a strong cry. He is very active. Acrocyanosis is noted. Heart rate is 98 bpm and breathing is strong. What is this child’s Apgar score?
Your Answer: 8
Correct Answer: 5
Explanation:The Apgar test scores appearance, pulse, grimace, activity, and respiration and is generally done at 1 and 5 minutes after birth but may be repeated if the child continues to score low (Table). This child’s score is as follows: Appearance, 1; Pulse, 1; Grimace, 2; Activity, 2; Respiration, 2 (APGAR score = 8). A score of 3 or less is generally regarded as critically low, 4 to 6 is fairly low, and 7 to 10 is generally normal. Contrary to common belief, the Apgar score is not used to decide if a neonate requires resuscitation. Decisions about resuscitation are based on emergency assessment of airway, breathing, and circulation.5,6

A 28-year-old woman presents for an antenatal visit in her first pregnancy. The pregnancy has been progressing normally thus far. Her routine mid-trimester ultrasound examination, performed at 18 weeks of gestation, shows that the placenta occupies the lower part of the uterus. It is noted that the placenta is reaching to within 1 cm of the internal cervical os. The patient is wondering what this means for her pregnancy and what needs to be done about it.
Which one of the following would be the most appropriate management?Your Answer: Repeat the ultrasound examination in 4 weeks' time.
Correct Answer: Repeat the ultrasound at 34 weeks of gestation.
Explanation:This patient is presenting with a low-lying placenta at 18 weeks of gestation. This is a common finding on ultrasound at 18-20 weeks. If there is not bleeding, there is an 80-90% chance that by late pregnancy, the placenta will have moved and is no longer occupying the lower uterine segment. For this reason, the repeat ultrasound examination is usually performed at 32-34 weeks of gestation. Further discussions about management can then be made after obtaining those results.
Leaving the repeat ultrasound until term would be inappropriate as intervention would be needed prior. If the placenta praevia is still present, it is typically advisable to deliver prior to term.
Cardiotocographic (CT) fetal heart rate monitoring is not required in the absence of bleeding or other symptoms.
Delivery by Caesarean section would not be necessary if the placenta was no longer praevia by the time the repeat ultrasound is done.
Repeat ultrasound examination at 22 weeks of gestation would also unnecessary and inappropriate as it is too close in time for the change to occur.

During early pregnancy, a pelvic examination may reveal that one adnexa is slightly enlarged. This is most likely due to:
Your 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.

A 39-year-woman visits a gynaecological clinic for fertility advice. She is unable to conceive for the last 2 years. Pelvic ultrasound shows 3-4 follicles in both ovaries. An endocrinological profile is ordered showing low oestrogen, elevated FSH, and LH.
What is the most suitable advice for her?Your Answer: In-vitro fertilization
Explanation:Premature menopause has been diagnosed biochemically in this patient. Menopause is considered premature when it happens without warning in a woman under the age of 40.
Follicular development is common in ultrasonography investigations of women with primary ovarian failure, but ovulation is rare. So this woman isn’t ovulating.Exogenous oestrogen treatment in physiologic amounts does not appear to improve the rate of spontaneous ovulation.
Women with primary ovarian failure from any cause may be candidates for donor oocyte in vitro fertilisation (IVF).Oestrogens, clomiphene citrate, and danazol are examples of treatment approaches that have been shown to be ineffective in patients with premature ovarian failure.

Meconium liquor passage was noted during the labour. Cardiotocography was done and revealed a fetal heart rate (FHR) of 149bpm. There were no noted decelerations or accelerations. The beat-to-beat variability is established at 15 bpm. Upon vaginal examination, there were no reported abnormalities.
Which of the following is considered to be the next most appropriate step in managing this patient?Your Answer: The CTG is normal and close monitoring until delivery is all required for now
Explanation:Meconium is the earliest stool of a newborn. Occasionally, newborns pass meconium during labour or delivery, resulting in a meconium-stained amniotic fluid (MSAF).
No particular cardio-tocograph pattern can be considered to have a poor prognostic value in the presence of thick MSAF and the decision to deliver and the mode of delivery should be based on the overall assessment and the stage and progress of labour. While management should be individualized, a higher Caesarean section rate in thick MSAF can be justified to ensure a better outcome for the neonate even in the presence of a normal CTG trace.

A 29-year-old woman presented to the emergency department with severe nausea and vomiting at 8 weeks of being pregnant. She is unable to take solid food but is capable of drinking small sips of liquids. She is concerned that she might have gastroenteritis because her partner was noted to have recently been diagnosed with it.
Which of the following is considered the next best step to investigate given the situation?Your Answer: Quantitative 13- HCG
Correct Answer: Pelvic ultrasound
Explanation:Hyperemesis gravidarum refers to intractable vomiting during pregnancy, leading to weight loss and volume depletion, resulting in ketonuria and/or ketonemia.
The exact cause of hyperemesis gravidarum remains unclear. However, there are several theories for what may contribute to the development of this disease process such as:
1. Hormone changes – hCG levels peak during the first trimester, corresponding to the typical onset of hyperemesis symptoms. Estrogen is also thought to contribute to nausea and vomiting in pregnancy.
2. Changes in the Gastrointestinal System – the lower oesophageal sphincter relaxes during pregnancy due to the elevations in estrogen and progesterone. This leads to an increased incidence of gastroesophageal reflux disease (GERD) symptoms in pregnancy, and one symptom of GERD is nausea.
3. Genetics – an increased risk of hyperemesis gravidarum has been demonstrated among women with family members who also experienced hyperemesis gravidarum.The average onset of symptoms happens approximately 5 to 6 weeks into gestation. The physical exam should include fetal heart rate (depending on gestational age) and an examination of fluid status, including an examination of blood pressure, heart rate, mucous membrane dryness, capillary refill, and skin turgor. A patient weight should be obtained for comparison to previous and future weights. If indicated, abdominal examination and pelvic examination should occur to determine the presence or absence of tenderness to palpation.

A 30-year-old G2P1 woman presented to the maternity unit, in labour at 38 weeks gestation. During her previous pregnancy she delivered a healthy baby through caesarean section. The current pregnancy had been uneventful without any remarkable problems in antenatal visits except for the first trimester nausea and vomiting.
On arrival, she had a cervical dilation of 4 cm and the fetal head was at -1 station. After 5 hours, the cervical length and fetal head station are still the same despite regular uterine contractions. Suddenly, there is a sudden gush of blood, which is approximately 1000 ml and the fetal heart rate have dropped to 80 bpm on CTG.
Which of the following could be the most likely cause for this presentation?Your Answer: Ruptured uterus
Explanation:Due to the previous history of caesarean section, uterine rupture would be the most likely cause of bleeding in this patient who is at a prolonged active phase of first stage of labour.
Maternal manifestations of uterine rupture are highly variable but some of its common features includes:
– Constant abdominal pain, where the pain may not be present in sufficient amount, character, or location suggestive of uterine rupture and may be masked partially or completely by use of regional analgesia.
– Signs of intra abdominal hemorrhage is a strong indication. Although hemorrhage is common feature, but signs and symptoms of intra-abdominal bleeding in cases of uterine rupture especially in those cases not associated with prior surgery may be subtle.
– Vaginal bleeding is not considered as a cardinal symptom as it may be modest, despite major intra-abdominal hemorrhage.
– Maternal tachycardia and hypotension
– Cessation of uterine contractions
– Loss of station of the fetal presenting part
– Uterine tenderness
As seen in this case, fetal bradycardia is the most common and characteristic clinical manifestation of uterine rupture, preceded by variable or late decelerations, but there is no other fetal heart rate pattern pathognomonic of rupture. Furthermore, fetal heart rate changes alone have a low sensitivity and specificity for diagnosing a case as uterine rupture.
Pain and persistent vaginal bleeding despite the use of uterotonic agents are characteristic for postpartum uterine rupture. If the rupture extends into the bladder hematuria may also occur.
A definite diagnosis of uterine rupture can be made only after laparotomy. Immediate cesarean section should be performed to save both the mother and the baby in cases where uterine rupture is suspected. -

A 38 year old woman has had amenorrhea for a year now. She admits she stopped her COCP treatment 18 months ago. Her blood exams reveal the following: FSH=8, LH=7, Prolactin=400, Oestradiol=500. What is the most likely diagnosis?
Your Answer: Prolactinoma
Correct Answer: Hypothalamic amenorrhea
Explanation:Functional Hypothalamic Amenorrhea (FHA) is a form of chronic anovulation, due to non-identifiable organic causes and often associated with stress, weight loss, excessive exercise, or a combination thereof. Investigations should include assessment of systemic and endocrinologic aetiologies, as FHA is a diagnosis of exclusion. A multidisciplinary treatment approach is necessary, including medical, dietary, and mental health support. Medical complications include, among others, bone density loss and infertility.

From which of the following spinal segments do both the internal and external anal sphincters receive their innervation?
Your Answer: S3
Correct Answer: S4
Explanation:The anal sphincters are responsible for closing the anal canal to the passage of faeces and flatus. The smooth muscle of the involuntary internal sphincter sustains contraction to prevent the leakage of faeces between bowel movements and is innervated by the pelvic splanchnic nerves, which are a branch of the spinal segment 4. The external sphincter is made up of skeletal muscle and can therefore contract and relax voluntarily. Its innervation comes from the inferior rectal branch of the pudendal nerve, and the perineal branch of S4 nerve roots.

An 8 week pregnant female presents to the ob-gyn with bleeding from the vagina for the last two days. Bimanual examination reveals the uterus to be 8 weeks in size. On speculum examination, the cervical os is closed. How would the fetal viability be confirmed?
Your Answer: Transvaginal ultrasound
Explanation:Indication for a transvaginal ultrasound during pregnancy include:
– to monitor the heartbeat of the foetus
– look at the cervix for any changes that could lead to complications such as miscarriage or premature delivery
– examine the placenta for abnormalities
– identify the source of any abnormal bleeding
– diagnose a possible miscarriage
– confirm an early pregnancyThis is an ultrasound examination that is usually carried out vaginally at 6-10 weeks of pregnancy.
The aims of this scan are to determine the number of embryos present and whether the pregnancy is progressing normally inside the uterus.
This scan is useful for women who are experiencing pain or bleeding in the pregnancy and those who have had previous miscarriages or ectopic pregnancies.

You're assessing a 34-year-old lady who suffers from chronic pelvic pain. She experiences cyclic pain, mostly throughout her premenstrual and menstrual periods. She has been trying for 15 months to conceive without luck. Her pelvic check-up comes out normal.
Which of the following tests would be most useful in diagnosing the source of her pain and planning preoperative disease staging?Your Answer: MRI
Explanation:Endometriosis is a chronic gynaecological condition affecting women of reproductive age and may cause pelvic pain and infertility. It is characterized by the growth of functional ectopic endometrial glands and stroma outside the uterus and includes three different manifestations: ovarian endometriomas, peritoneal implants, deep pelvic endometriosis. The primary locations are in the pelvis; extra pelvic endometriosis may rarely occur.
Diagnosis requires a combination of clinical history, invasive and non-invasive techniques. The definitive diagnosis is based on laparoscopy with histological confirmation. Diagnostic imaging is necessary for treatment planning. MRI is as a second-line technique after ultrasound. The MRI appearance of endometriotic lesions is variable and depends on the quantity and age of haemorrhage, the amount of endometrial cells, stroma, smooth muscle proliferation and fibrosis. The purpose of surgery is to achieve complete resection of all endometriotic lesions in the same operation.
Owing to the possibility to perform a complete assessment of all pelvic compartments at one time, MRI represents the best imaging technique for preoperative staging of endometriosis, in order to choose the more appropriate surgical approach and to plan a multidisciplinary team work.
Though ESR maybe elevated due to the presence of inflammation, it is not specific for endometriosis and has no role in preoperative staging. The same holds true for any possible CBC finding.
Transvaginal ultrasound is preferred for diagnosis but doesn’t aid in preoperative staging of endometriosis.
CA125 values are elevated in severe infiltrative endometriosis but unchanged in mild disease. Relaying on CA125 cause a high rate of false negatives.

Sensory supply to the clitoris is via branches of which nerve?
Your Answer: Pudendal nerve
Explanation:The pudenal nerves has three branches, namely the inferior rectal, perineal and the dorsal nerve of the clitoris. The perineal nerve has two branches: The superficial perineal nerve gives rise to posterior scrotal or labial (cutaneous) branches, and the deep perineal nerve supplies the muscles of the deep and superficial perineal pouches, the skin of the vestibule, and the mucosa of the inferior most part of the vagina. The inferior rectal nerve communicates with the posterior scrotal or labial and perineal nerves. The dorsal nerve of the penis or clitoris is the primary sensory nerve serving the male or female organ, especially the sensitive glans at the distal end.

At the time of delivery, if there is a laceration of perineal body but not the anal sphincter, this type of laceration is classified as?
Your Answer: Second degree
Explanation:Perineal tears are common at the time of child birth. First degree perineal laceration means that the wound is so small that it doesn’t require any stitches and usually heals on its own. 2nd degree means that skin and smooth muscles are both torn. 3rd degree tear means that the tear is beyond the perineal muscles and the muscles surrounding the anal canal, while in 4th degree, the perineal tear goes through the anal sphincter up to the rectum.

A 49-year-old lady presents with amenorrhea of 11-months’ duration. Her periods were previously normal and regular. She is planned for an assessment of her FSH (follicle-stimulating hormone) and oestradiol (E2) levels.
Assuming she has attained menopause, which pattern would most likely be found?Your Answer: High FSH and low E2.
Explanation:High FSH and low E2 levels would be expected in menopause. FSH levels would be raised as her body attempts to stimulate ovarian activity and E2 would be low due to reduced ovarian function. The other options would be possible if she was younger, and if occurring with amenorrhea, would warrant further hormonal tests.
It is often challenging to interpret hormone test results close to the time of menopause, especially if the woman is still experiencing irregular menstruation, as remaining ovarian follicles might still produce oestrogen, causing both bleeding and FSH suppression. Elevation of FSH then can be seen again once the oestrogen level drops. Hence, the results would be influenced by the timing of blood sample collection. Once amenorrhea occurs more consistently, it would be easier to interpret the results.

Endometrial ablation is a medical technique that removes or destroys the endometrial lining in women who have severe monthly flow.
Endometrial ablation is not contraindicated by which of the following?Your Answer: Post-menopausal women
Correct Answer: Completed family
Explanation:Endometrial ablation is primarily intended to treat premenopausal women with heavy menstrual bleeding (HMB) who do not desire future fertility. Women who choose endometrial ablation often have failed or declined medical management.
Absolute contraindications to endometrial ablation include pregnancy, known or suspected endometrial hyperplasia or cancer, desire for future fertility, active pelvic infection, IUD currently in situ, and being post-menopausal. In general, endometrial ablation should be avoided in patients with congenital uterine anomalies, severe myometrial thinning, and uterine cavity lengths that exceed the capacity of the ablative technique (usually greater than 10-12 cm).

Urine dipstick examination is negative for both leukocytes and nitrites but is positive for ketones. Serum ketone level is elevated and other electrolytes including blood glucose levels are within normal range.
Which of the below mentioned treatment options is not appropriate in this situation?Your Answer: Encourage oral intake and discharge home
Explanation:Patient mentioned in the case has developed severe nausea and vomiting at the initial weeks of pregnancy. If the following clinical features are present, it confirms the diagnosis of hyperemesis gravidarum:
– Weight loss of more than 5% of pre-pregnancy weight
– Moderate to severe dehydration.
– Ketosis
– Electrolyte abnormalities.Management of hyperemesis gravidarum include:
– Temporary suspension of oral intake, followed by gradual resumption.
– Intravenous fluid resuscitation, beginning with 2 L of Ringer’s lactate infused over 3 hours to maintain a urine output of more than 100 mL/h.
– Use of Antiemetics like metoclopramide, if needed.
– Oral administration of Vitamin B6.
– Replacement of electrolytes if required in the case.Encouraging oral intake and sending this patient home without any intravenous hydration, is not considered the correct treatment option in this case.

A 33-year-old lady seeks counsel from your clinic since she has a history of deep vein thrombosis. She was on progesterone-only tablets (POP) until five months ago, when she decided to get pregnant. However, the pregnancy turned out to be ectopic. Thankfully, she made it through. She doesn't want to get pregnant again and asks if she may resume taking the tablets.
Which of the following is the best piece of advise you could give?Your Answer: She should take anticoagulants along with combined oral contraceptive pills
Correct Answer: She cannot take progesterone only pills
Explanation:Oestrogen-containing contraceptives are not recommended for this woman since she has a history of DVT. This is most likely why she was started on POP instead of standard combination tablets prior. Progesterone is also contraindicated with a history of ectopic pregnancy and should never be used again. Barrier approaches, for example, could be applied in this woman’s case.
The following are absolute contraindications to taking just progesterone pills:
– Pregnancy
– Breast cancer
– Vaginal bleeding that hasn’t been diagnosed
– Ectopic pregnancy history or a high risk of ectopic pregnancyProgesterone-only pills have the following relative contraindications:
– Active viral hepatitis
– Severe chronic liver disease
– Malabsorption syndrome
– Severe arterial disease
– Successfully treated breast cancer more than 5 years ago
– Concomitant use of hepatic enzyme inducing medications. -

Which of the following hormones is secreted by the corpus luteum in a non pregnant state?
Your Answer: Progesterone
Explanation:The corpus luteum is formed from the granulosa cells of the mature follicle. The structure functions as a transient endocrine organ which secretes mainly progesterone with additional secretion of oestradiol and inhibin, which serve to suppress FSH levels. In the event of no pregnancy, the corpus luteum stops producing progesterone and degenerates into the corpus albicans.

A 28 year old woman presents for a scan at 13 weeks. Though this is her second pregnancy, the first ended in a 1st trimester miscarriage. She has not reported any problems with the current pregnancy. The ultrasound scan showed a small gestational sac and no fetal cardiac activity.
Which of the following is the most likely diagnosis?Your Answer: Missed Miscarriage
Explanation:A miscarriage is defined as the spontaneous loss of a pregnancy before the age of viability at 24 weeks in the UK.
A missed miscarriage is described as a loss of pregnancy without vaginal bleeding, loss of tissue, cervical changes or abdominal pain. During a scan, a fetal heartbeat is not observed, and the gestational sac may be small.
A threatened miscarriage is when the cervix dilates and uterine bleeding is seen; the pregnancy could still be viable. A complete miscarriage occurs when all the products of conception are expelled from the uterus, bleeding has stopped, and the cervix has closed up after dilation.
An inevitable miscarriage occurs with the usual symptoms of a miscarriage and a dilated cervix, suggesting that the passage of the fetal tissue is inevitable.
Recurrent miscarriages are described as spontaneous pregnancy loss of more than 2 to 3 consecutive times.

A 43-year-old woman, with a history of bilateral tubal ligation, presents with regular but excessively heavy periods. She has a history of multiple uterine leiomyoma and her uterus is the size of a 12-week pregnancy.
Pap smear is normal; haemoglobin level is 93 g/L. She underwent dilatation and curettage 8 months ago but it did not result in symptom improvement nor was it able to find the underlying cause of her symptoms.
Which is the best next step in her management?Your Answer: Myomectomy,
Correct Answer: Total abdominal hysterectomy
Explanation:Oral progestogen therapy for 21 days (day 5-26) is considered effective but is only a short-term therapy for menorrhagia. Myomectomy should only be considered if the woman would like to conceive later on. Due to the recurrent nature of fibroids, it is likely that the woman would need more surgeries in the future, which is not ideal. Furthermore, if there is a large number of fibroids or the size of the fibroids are large, myomectomy would not be an option for reasons such as the feasibility. If myomectomy for multiple fibroids prove to be unsuccessful, the ultimate outcome would still have to be a hysterectomy.
In cases where there is significant enlargement of the uterus, endometrial ablation would be difficult and the long-term cure rate of symptoms would be considerably low. The best next step would be a total abdominal hysterectomy since it would solve her menorrhagia and within a few years’ time, she would be expected to attain menopause anyway. Ponstan or mefenamic acid has been found to be superior to tranexamic acid for menorrhagia. However, it can still prove to be ineffective in some cases and also not a long term solution.
