A 30-year-old woman at her 18th week of pregnancy has been diagnosed with deep vein thrombosis of iliofemoral veins.
Which of the following is considered the best management for the patient's condition?Your Answer: Therapeutic dose of low molecular weight heparin for 6 months
Explanation:Deep venous thrombosis (DVT) during pregnancy is associated with high mortality, morbidity, and costs. Pulmonary embolism (PE), its most feared complication, is the leading cause of maternal death in the developed world. DVT can also result in long-term complications that include post thrombotic syndrome (PTS) adding to its morbidity. Women are up to 5 times more likely to develop DVT when pregnant. The current standard of care for this condition is anticoagulation.
Low molecular weight heparin (LMWH) is the preferred agent for prophylaxis and treatment of DVT during pregnancy. A disadvantage of LMWH over unfractionated heparin (UFH) is its longer half-life, which may be a problem at the time of delivery.

A couple has decided to practice the daily basal body temperature assessment (BBT) as a means of contraception. Over the past year, her cycles varied in length from 24 to 30 days with menses lasting 4 days. They do not have sexual intercourse when she is on her period.
Which regimen would be the most suitable to minimise the chances of getting pregnant?Your Answer: No intercourse in the follicular phase of the cycle, commence intercourse two days after temperature elevation of 0.3°C and continue thereafter.
Explanation:The best regimen would be to have no intercourse in the follicular phase of the cycle and then commence it two days after a temperature rise of 0.3C and continue then onwards. When deciding the best contraceptive method, one has to consider two factors-the duration of survival of sperm in the uterus and body temperature in relation to ovulation. For this case, since her cycle length varies from 24 to 30 days, the earliest time in which ovulation would occur would be 14 days before her shortest cycle i.e. day 10. Intercourse has to be avoided from day 4 of her cycle just in case the current cycle is short because sperm can survive up to 6 days in the uterus. Day 4 would be the day her menses would end and as this couple avoids intercourse during her menstruation, there would be no intercourse during the follicular phase of her cycle.
During ovulation, her serum progesterone levels would start to increase, causing a 0.3°C to 0.4°C increase in her body temperature within 2-3 days of ovulating. This elevation in temperature would remain until close to when her period starts. The ovum can only be fertilised for roughly 24 hours after ovulation has taken place. Resuming sexual intercourse once her temperature has risen for 2 days would suggest that ovulation had already taken place 3-4 days earlier and so it is unlikely for pregnancy to occur.
Options that include intercourse during any part of her follicular phase is not correct. Hence, the only option that satisfies the above criteria would be intercourse avoidance during her follicular phase and to resume 2 days following a rise of 0.03°C in body temperature.

You are discussing a planned Caesarean Section (CS) with a patient. Which of the following risks is reduced with CS?
Your Answer: Neonatal intensive care admission
Correct Answer: Early postpartum haemorrhage
Explanation:There are many different reasons for performing a delivery by Caesarean section. The four major indications accounting for greater than 70 per cent of operations are: 1. previous Caesarean section 2. dystocia 3. malpresentation 4. suspected acute fetal compromise. Other indications, such as multifetal pregnancy, abruptio placenta, placenta praevia, fetal disease and maternal disease are less common. The chances of early postpartum haemorrhage are greatly reduced in C-section deliveries.

With sneezing, a 45-year-old mother of two reported leaking a small bit of urine. It started to happen with exercising recently. She denies having experienced recent life pressures.
Which of the following best characterizes the incontinence she's dealing with?Your Answer: Stress incontinence
Explanation:Overflow incontinence typically presents with continuous urinary leakage or dribbling in the setting of incomplete bladder emptying. Associated symptoms can include weak or intermittent urinary stream, hesitancy, frequency, and nocturia. When the bladder is very full, stress leakage can occur or low-amplitude bladder contractions can be triggered resulting in symptoms similar to stress or urgency incontinence.
Women with urgency incontinence experience the urge to void immediately preceding or accompanied by involuntary leakage of urine
Individuals with stress incontinence have involuntary leakage of urine that occurs with increases in intraabdominal pressure (e.g., with exertion, sneezing, coughing, laughing) in the absence of a bladder contraction.

You are called to see a 24 year old patient who is currently in labour but is failing to progress. A fetal blood sample is sent for analysis. pH is 7.22. Which of the following is the appropriate course of action?
Your Answer: Repeat in 30 minutes if CTG remains abnormal
Correct Answer: Consider delivery
Explanation:A normal pH value is above 7.25. A pH below 7.20 is confirmation of fetal compromise. Values between 7.20 and 7.25 are ‘borderline’.
The base deficit can also be useful in interpretation of the fetal scalp pH. A base excess of more than -10 demonstrates a significant metabolic acidosis, with increasing risk of fetal neurological injury beyond this level. Delivery should be considered.

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.

Which of the following best describes the mechanism of action of radiotherapy?
Your Answer: DNA damage via free radical generation
Explanation:Radiotherapy causes ionisation, primarily of water. This leads to hydroxyl and other free radicals being generated. Free radicals are highly reactive and cause DNA damage to cells via their reactions with them. Free radicals are relatively short lived and eventually form stable compounds. The DNA damage leads to cellular death.

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: Serial ultrasound for fetal weight estimation
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. -

A 25-year-old gravida 1 para 0 woman, at her 36 weeks of gestation, is brought to the emergency department by her mother due to a seizure. Patient was sitting outside when she suddenly had a 2-minute seizure with loss of urinary continence and is still confused when she arrived at the emergency department. Her mother reports that the patient had severe anxiety and had been acting out for the past several days. Her only surgery was a splenectomy after a motor vehicle collision last year.
On physical examination patient's temperature is 37.7 C (99.9 F), blood pressure is 158/98 mm Hg, and pulse is 120/min. Patient seems agitated and diaphoretic with bilaterally dilated pupils.
On systemic examination:
Cranial nerves are intact, neck is supple and nontender.
Cardiopulmonary examination is normal.
The abdomen is gravid without any rebound or guarding and the uterus is nontender.
There is 2+ pitting pedal edema bilaterally. Sensations and strength are normal in the bilateral upper and lower extremities.
Laboratory results are as follows:
a) Complete blood count shows
- Hematocrit: 33%
- Platelets: 140,000/mm3
- Leukocytes: 13,000/mm3
b) Serum chemistry
- Sodium: 124 mmol/L
- Potassium: 3.4 mmol/L
- Chloride: 96 mmol/L
- Bicarbonate: 21 mmol/L
- Blood urea nitrogen: 6.43 umol/L
- Creatinine: 70.7 umol/L
- Glucose: 4.4 mmol/L
c) Urinalysis
- Protein: none
- Ketones: present
CT scan of the head is normal.
Which of the following is most likely the diagnosis in this patient?Your Answer: Eclampsia
Correct Answer: Amphetamine intoxication
Explanation:This patient at 36 weeks of gestation likely had a generalized tonic-clonic seizure. A new-onset seizures in pregnancy can be due to either due to eclampsia which is pregnancy-specific or due to other non-obstetric causes like meningitis, intracranial bleeding etc.
In pregnant and postpartum women eclampsia is the most common cause for seizures which is classically associated with preeclampsia, a new-onset hypertension at ≥20 weeks gestation, with proteinuria and/or signs of end-organ damage. Although this patient has hypertension, absence of proteinuria and the additional findings like agitation, dilated pupils, hyponatremia and normal head CT scan are suggestive of another etiology. Patients with eclampsia will show white matter edema in head CT scan.
Amphetamine intoxication, which causes overstimulation of the alpha-adrenergic receptors resulting in tachycardia, hypertension and occasional hyperthermia, might be the cause for this patient’s seizures. Some patients will also have diaphoresis and minimally reactive, dilated pupils and severe intoxication can lead to electrolyte abnormalities, including significant hyponatremia (possibly serotonin-mediated) and resultant seizure activity.
Confirmation of Amphetamine intoxication can be done by a urine drug testing. it is essential to distinguishing between eclampsia and other causes of seizure in this case, as it will help to determine whether or not there is need for an emergency delivery.Altered mental status and electrolyte abnormalities can be due to heat stroke, however, patients affected this way will have an elevated temperature of >40 C /104 F associated with hemodynamic instabilities like hypotension.
Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a hypertensive disorder of pregnancy which can result in seizures (ie, eclampsia), but this patient’s hematocrit level is normal without any hemolysis, also patients with HELLP syndrome typically presents with a platelet count <100,000/mm3. Seizures and altered mental status in patients with prior splenectomy can be due to pneumococcal meningitis however, such patients will present with high fever and nuchal rigidity, making this diagnosis less likely in the given case. Amphetamine intoxication can present with hypertension, agitation, diaphoresis, dilated pupils, and a generalized tonic-clonic seizure due to hyponatremia, which is most likely to be the case here.

A 41-year-old lady visits your clinic to talk about the results of her cervical screening test. According to the study, she has a low-grade squamous intraepithelial lesion as well as HPV non-16 and 18 subtypes. She had never previously had a cervical screening.
What is the best course of action for her management?Your Answer: Repeat HPV test in 12 months
Explanation:An LSIL Pap test shows mild cellular changes. The risk of a high-grade cervical precancer or cancer after an LSIL Pap test is as high as 19 percent.
As with an ASC-US Pap test, an LSIL Pap test is evaluated differently depending upon age. For women ages 25 or older, follow-up depends upon the results of human papillomavirus (HPV) testing:
– Women who test positive for HPV or who have not been tested for HPV should have colposcopy.
– Women who test negative for HPV can be followed up with a Pap test and HPV test in one year.All other options are not acceptable for the above mentioned reasons.

You receive a swab result from a patient who had complained of odorous vaginal discharge. It confirms bacterial vaginosis (BV). Which pathogen is most commonly associated with BV?
Your Answer: Gardnerella vaginalis
Explanation:Bacterial vaginosis is characterised by a foul smelling vaginal discharge without inflammation. The most common spp to cause this is gardnerella vaginalis. Other spp include mycoplasma hominis and bacteroides. It occurs due to growth and increase in anaerobic spp with simultaneous reduction in lactobacilli in vaginal flora causing an increase in vaginal pH. It is the most common cause of abnormal vaginal discharge in women of childbearing age.

A pregnant woman who is a heavy smoker, observed some thick white patches on the inside of her mouth. Her oral cavity appears inflamed on examination. Which diagnosis is most likely correct?
Your Answer: Candidiasis
Explanation:During pregnancy, the chances for a woman to develop oral candidiasis double. An aphthous ulcer has a yellowish floor which is surrounded by an erythematous halo while in lichen planus, the lesions do not have the appearance of a thick white mark but are more or less lace-like. The lesions in leucoplakia have raised edges and they appear as bright white patches which are sharply defined and cannot be rubbed out. Smoking may affect the tongue, producing tongue coating. In this case the tongue is just inflamed which is a sign of 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: 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.

You are asked to consult on a young woman with a pre-existing cardiac defect. She wants to become pregnant in the near future and seeks advice about what risks to her health that this will create. You tell that the highest maternal mortality rates are associated with which of the following cardiac defects:
Your Answer: Mitral stenosis
Correct Answer: Eisenmenger syndrome
Explanation:Eisenmenger’s syndrome is one where there is communication between the systemic and pulmonary system, along with increased pulmonary vascular resistance, either to systemic level or above systemic level (right to left shunt). A would-be mother must be informed that to become pregnant would incur a 50% risk of dying. Even if she survives, fetal mortality approaches 50% as well.
– Severe symptomatic aortic stenosis has a mortality in pregnancy of about 20%. Prevention of reduction in preload is necessary in all obstructive cardiac lesions. Balloon valvuloplasty can be done in pregnancy.
– Due to the increased blood volume and cardiac output in pregnancy, mitral stenosis can lead to severe pulmonary oedema. Balloon valvuloplasty can be done in pregnancy.
– Ebstein anomaly is a malformation of the tricuspid valve- It is usually not associated with maternal mortality.
– Atrial-septal defects rarely cause complications in pregnancy, labour, or delivery. -

Among the following which is the most likely finding of placental abruption in a pregnant woman?
Your Answer: Uterine tenderness
Correct 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.

You're looking after a 24-year-old woman who is experiencing pelvic pain. She has one-sided pain that is widespread and mild, but can be intense at times. Menstruation has been regular. She denies having fever.
With the exception of a smooth movable adnexal mass on the right side, her pelvic examination seems normal.
Which of the following is the most likely reason for your discomfort?Your Answer: Ovarian cyst
Explanation:An ovarian cyst is a sac filled with liquid or semiliquid material that arises in an ovary. Although the discovery of an ovarian cyst causes considerable anxiety in women owing to fears of malignancy, the vast majority of these lesions are benign. Most patients with ovarian cysts are asymptomatic, with the cysts being discovered incidentally during ultrasonography or routine pelvic examination. Some cysts, however, may be associated with a range of symptoms, sometimes severe, including the following:
Pain or discomfort in the lower abdomen
Severe pain from torsion (twisting) or rupture – Cyst rupture is characterized by sudden, sharp, unilateral pelvic pain; this can be associated with trauma, exercise, or coitus. Cyst rupture can lead to peritoneal signs, abdominal distention, and bleeding (which is usually self-limited)
Discomfort with intercourse, particularly deep penetration
Changes in bowel movements such as constipation
Pelvic pressure causing tenesmus or urinary frequency
Menstrual irregularities
Precocious puberty and early menarche in young children
Abdominal fullness and bloating
Indigestion, heartburn, or early satiety
Endometriomas – These are associated with endometriosis, which causes a classic triad of painful and heavy periods and dyspareunia
Tachycardia and hypotension – These may result from haemorrhage caused by cyst rupture
Hyperpyrexia – This may result from some complications of ovarian cysts, such as ovarian torsion
Adnexal or cervical motion tendernessUnderlying malignancy may be associated with early satiety, weight loss
achexia, lymphadenopathy, or shortness of breath related to ascites or pleural effusionThe absence of fever or vaginal discharge rules out PID
The absence of pain on the right lower quadrant, fever, nausea and vomiting rule out appendicitis.
The patient has regular menses, no vaginal bleeding no signs of shock that rules out ectopic pregnancy.
her symptoms are also not consistent with the presentation of leiomyoma. Leiomyoma presents with enlarged uterus, pelvic pressure. It early causes pain when it is complicated with red degeneration which usually occurs in pregnancy.

Explanation:This is a patient that recently gave birth and is still breastfeeding presenting with dyspareunia. The most likely cause would be a thin atrophic vaginal epithelium. This is very common presentation and is due to the low oestrogen levels due to the prolactin elevation from breastfeeding.
An unrecognised and unsutured vaginal tear should have healed by this time and should not be causing issues.
Endometriosis tends to resolve during a pregnancy, but if this was the issue, it would have caused dyspareunia prior to pregnancy.
Vaginal infective causes of dyspareunia, such as monilial or trichomonal infections, are rare in amenorrhoeic women.

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.

Regarding blood volume in pregnancy which of the following statements is TRUE?
Your Answer: Blood volume slowly increases by 40-50%
Explanation:Maternal blood volume expands during pregnancy to allow adequate perfusion of vital organs, including the placenta and foetus, and to anticipate blood loss associated with delivery. The rapid expansion of blood volume begins at 6–8 weeks gestation and plateaus at 32–34 weeks gestation. While there is some increase in intracellular water, the most marked expansion occurs in extracellular fluid volume, especially circulating plasma volume. This expanded extracellular fluid volume accounts for between 8 and 10 kg of the average maternal weight gain during pregnancy. Overall, total body water increases from 6.5 to 8.5 L by the end of pregnancy.

An 20-year-old woman presents to you 6 hours after she was raped on day-12 of her menses which usually lasts for 28 days. You have decided to give her Postinor-2 (levonorgestrel 0.75 mg) as a post-intercourse contraceptive. She is requesting information about any potential adverse effects as well as its efficacy.
Which of the following statements is correct?Your Answer: The treatment fails to prevent pregnancy in 2-3% of women treated.
Explanation:Postinor-2 (levonorgestrel 750pg) is only an emergency contraceptive and is not designed to be a regular form of contraception. If taken within 24 hours, it is estimated to be able to prevent up 97-98% of pregnancies and 58% if given between 48-72 hours post-unprotected intercourse. It can cause vaginal bleeding within a few days of its administration if it is given before day 8-10 of her menstrual cycle. However, if given mid-cycle, it typically doesn’t affect the timing of her next period unless conception occurs. Nausea and vomiting were common when high doses of OCP were used as a post-intercourse contraceptive. Nausea and vomiting still can occur with Postinor-2, but not up to 50% of women. There is currently no evidence to suggest that the levonorgestrel dose would cause a virilising effect on female foetuses.

A couple both in their late 20s come to you for a review as they have been trying to fall pregnant for the past 3 years.
She has a history of fallopian tube surgery following tubal obstruction which was diagnosed laparoscopically. During the surgery, there was evidence of mild endometriosis with uterosacral ligaments involvement. She has amenorrhea and galactorrhoea. On the other hand, his semen specimens have been persistently severely abnormal.
Which is the most appropriate management?Your Answer: She should be treated with the dopamine agonist bromocriptine.
Correct Answer: They should use intracytoplasmic sperm injection (ICSI) in IVF,
Explanation:The most suitable treatment would be to use intracytoplasmic sperm injection (ICSI) in IVF. If hyperprolactinemia was the isolated underlying cause for the infertility, then treatment with a dopamine agonist would be suitable. However, since it is not the sole contributing factor, it is unlikely to be effective in this case. The same reasoning can be applied to the use of danazol to treat any remaining endometriosis.
Unfortunately, there is no treatment (including gonadotrophin injections) that would improve the severely abnormal semen specimen. The most appropriate option would be to use intracytoplasmic sperm injection (ICSI) with IVF. Through this method, any remaining tubal issues would be bypassed. Furthermore, it would be useful in mild endometriosis cases and would also treat the amenorrhea resulting from hyperprolactinemia. There is no justification to perform another laparoscopy to either check or treat endometriosis or any remaining tubal obstruction.

A 35-year-old woman from the countryside of Victoria comes to the hospital at 37 weeks of gestation after noticing a sudden gush of clear fluid from her vagina.
Speculum examination shows pooling of liquor in the posterior fornix and patient developed fever, tachycardia and chills 12 hours after this episode.
Apart from giving antibiotics, what will be your strategy in management of this case?Your Answer: Continue pregnancy until natural delivery
Correct Answer: Induce labour now
Explanation:Above mentioned patient presented with symptoms of premature rupture of membranes (PROM) which refers to membrane rupture before the onset of uterine contractions.
A sudden gush of clear or pale yellow fluid from the vagina is the classic clinical presentation of premature rupture of membranes. Along with this the patient also developed signs of infection like fever, tachycardia and sweating which is suggestive of chorioamnionitis.
Vaginal examination is never performed in patients with premature rupture of membrane, instead a speculum examination is the usually preferred method which will show fluid in the posterior fornix.
The following are the steps in management of premature rupture of membrane:
– Admitting the patient to hospital.
– Take a vaginal
ervical smears.
– Measure and monitor both white cell count and C- reactive protein levels.
– Continue pregnancy if there is no evidence of infection or fetal distress.
– In presence of any signs of infection or if CTG showing fetal distress it is advisable to induce labour.
– Corticosteroids must be administered if delivery is prior to 34 weeks of gestation.
– Give antibiotics as prevention and for treatment of infection. -

A 26 year old female patient comes to a GP asking to see a gynaecologist for cervical screening test. She has no history of sexual intercourse and is not a lesbian.
What would you do next?Your Answer: Call the gynaecologist for advice
Correct Answer: Reassure her there is no need for cervical screening test at this stage
Explanation:Women, who have never had sexual encounter, do not need cervical screening. However, any sort of sexual encounter (Lesbian or heterosexual) is considered a risk and the patient must be screened. Otherwise, routine cervical screening test can be performed every five years for woman 25-74 years who ever had sex with no evidence of cervical pathology. Perform a cervical screening test at the age of 25 or 2 years after first sexual intercourse-whichever is later in sexually active women. Perform cervical screening test in patients above 75 years if they request or if they never had any symptoms.

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 28-year-old woman who recently got married presents to your clinic.
She has a history of extremely irregular menstrual cycles with the duration varying between four and ten weeks.
She had attended her routine review appointment one week prior to her current presentation.
At that time she had stated that her last period had occurred six weeks previously.
You had recommended the following tests for which the results are as shown below:
Serum follicle-stimulating hormone (FSH): 3 IU/L (<13)
Serum luteinising hormone (LH): *850 IU/L (4-10 in follicular phase, 20-100 at mid-cycle)
Serum prolactin (PRL): 475 mU/L (50-500)
Which one of the following is the most probable reason for her amenorrhoea?Your Answer: Stress from her recent marriage.
Correct Answer: Early pregnancy.
Explanation:All of the options provided could cause amenorrhoea and therefore need to be evaluated.
The luteinising hormone (LH) level reported here is exceedingly elevated. A patient with polycystic ovarian syndrome (PCOS) is unlikely to have such a raised level, but it could be because of a LH-producing adenoma. Such tumours are, however, extremely rare.
Early pregnancy (correct answer) is the most likely cause of this woman’s elevated LH level. This would be due to the presence of beta human chorionic gonadotropin (hCG) hormone that is produced during pregnancy.
LH and beta-HCG both have similar beta-subunits and cross-reactions are commonly noted in LH assays.
The serum prolactin (PRL) level is at the upper end of the normal range and this correlates to the levels observed in the early stages of pregnancy.
The follicle-stimulating hormone (FSH) levels remain low during early pregnancy.
If her amenorrhea had been caused by stress from her recent marriage, the LH level would have been normal or low.
If the cause was premature ovarian failure, the FSH level would have been significantly higher.

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: Prescribe her with urinary alkalinisers while waiting for urinary microbiology and sensitivity
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 36-year-old woman presents to your clinic with cyclical mastalgia. Physical examination reveals that her breasts are normal. She has a family history of her mom who developed breast cancer at the age of 45 years and subsequently died from metastases. She states that her patient's maternal grandmother also had breast cancer before the age of 50.
The patient is on the oral contraceptive pill (OCP) and no other medications. She is generally healthy overall. Recent mammography results are also normal. An ultrasound of the breasts shows an uncomplicated cyst with no concerning features in the right breast.
Apart from advice about the use of simple analgesics and evening primrose oil for her mastalgia, which one of the following is the most appropriate management in the patient's follow-up regimen?Your Answer: Cease the OCR, yearly clinical review, yearly mammography and ultrasound.
Correct Answer: Remain on the OCP, six-monthly clinical review, yearly mammography and ultrasound.
Explanation:This is a case of a woman who presented with cyclical breast pain that is on an OCP and with a family history of breast cancer. Those with a family history of breast cancer in more than one blood relative (parent, sibling, grandparent) have a significantly higher chance of developing breast cancer than women with no family history. Regular six-monthly clinical review and yearly mammographic screening, with or without ultrasound screening, should start at least five years before the age of the diagnosis in the blood relatives.
The consensus now is that any additional risk of breast cancer from the oestrogen in the oral contraceptive pill (OCP) is less than the risk of unwanted pregnancy when using alternative, and perhaps less effective, contraception. Thus, the patient would not be advised to stop the OCP.
With two blood relatives that developed breast cancer before the age of 50, this patient is in a high-risk group of developing breast cancer. Even so, 50% of such high-risk women will not develop a breast cancer in their lifetime. There are specialised familial cancer screening clinics are available for high-risk women where genetic testing can be discussed further. Women at high risk may electively have a bilateral subcutaneous mastectomy performed prophylactically which will bring the risk of breast cancer development to an irreducible minimum.

A 24-year-old woman is planning to conceive and comes for your advice. She has a history of juvenile myoclonic epilepsy and has been stable on sodium valproate. Despite your full explanations about the risks of the teratogenicity of antiepileptic drugs, she insists she wants to be a mother and asks you to guide her.
Among the following which would be the most appropriate advice to give this patient?Your Answer: Switch to lamotrigine
Correct Answer: Continue sodium valproate
Explanation:As they respond differently to different drugs, a thorough distinguishing must be done between the two major groups of epilepsies while approaching a woman, who wishes to become pregnant while on antiepileptic drugs.
Partial epilepsies will respond to most of the antiepileptic drugs, but in case of idiopathic generalized epilepsies, especially in juvenile myoclonic epilepsy, seizure can be controlled only with a reasonably low dose of sodium valproate. Although lamotrigine may be helpful but substitution of sodium valproate with lamotrigine is not the right choice. This is because lamotrigine is not as effective as sodium valproate and will sometimes worsens myoclonic seizures in juvenile myoclonic epilepsy.
Topiramate and levetiracetam are found to be effective in idiopathic generalized epilepsy, while carbamazepine, phenytoin and gabapentin may worsen some seizure types, especially in myoclonic and absence seizures. For some women with idiopathic generalized epilepsies, there will be no effective alternative to sodium valproate as cessation of sodium valproate will lead to recurrence of the generalized seizures, especially juvenile myoclonic epilepsy. Hence, it is not advisable to discontinue the drug in auch patients.
On the other hand, sodium valproate have the highest reported teratogenicity potential among antiepileptic drugs and the Australian Pregnancy Register has reported the risk to be as high as 16% if used in first trimester. Sodium valproate should be avoided in women of reproductive age and if a patient on the medication is willing to become pregnant, she should be well informed about the risk of teratogenicity and the decision must be left to her. If she decides to accept the risks and continue with pregnancy, the lowest possible effective dose should be prescribed to her.
If the dose of sodium valproate has been reduced to minimum during pregnancy to reduce the possible teratogenesis, it is recommended to re-establish the prepartum effective dose before the onset of labor. This is because, it is the time with increased risk for seizures, especially in patients with idiopathic generalised epilepsy who are very sensitive to sleep deprivation. Valproate therapy is found to be safe during breastfeeding.

In a pregnant lady with polyhydramnios, the cause could be:
Your Answer: Patient is taking anti-epileptic drugs
Correct Answer: Foetus with oesophageal-atresia
Explanation:An underlying disease is only found in 17 % of cases in mild polyhydramnios. In contrast, an underlying disease is detected in 91 % of cases in moderate to severe polyhydramnios. The literature lists the following potential aetiologies: fetal malformations and genetic anomalies (8–45 %), maternal diabetes mellitus (5–26 %), multiple pregnancies (8–10 %), fetal anaemia (1–11 %), other causes, e.g. viral infections, Bartter syndrome, neuromuscular disorders, maternal hypercalcemia. Viral infections which can lead to polyhydramnios include parvovirus B19, rubella, and cytomegalovirus. Other infections, e.g. toxoplasmosis and syphilis, can also cause polyhydramnios.

Which of the following causes of polyhydramnios is more common?
Your Answer: Diabetes
Correct Answer: Idiopathic
Explanation:Maternal disorders, such as diabetes, in-utero infections, drug usage, placental abnormalities and fetal conditions as congenital and chromosomal abnormalities, Rh iso-immunization, and multiple gestations, are generally associated with polyhydramnios. Congenital abnormalities such as duodenal, oesophageal, or intestinal atresia of the foetus are the most common malformations that typically cause gastro-intestinal obstruction and interfere with fetal swallowing and/or absorption resulting with polyhydramnios. However, in about 70% of cases, none of the aforementioned aetiologies are causes of polyhydramnios, and it is referred to as idiopathic or isolated.

Which HPV subtypes are chiefly associated with causing cancer?
Your Answer: 16 and 18
Explanation:HPV 16 and 18 are responsible for 70% of cases of HPV related cancers. They are considered the most important high risk genotypes of HPV. As well as cervical cancer they are associated with cancers of the oropharynx and anogenital region.
There are over 100 genotypes of HPV including several other high risk HPV types. Gardasil® is a quadrivalent vaccine against HPV Types 6, 11, 16, and 18
HPV genotypes 6 and 11 are low risk and cause anogenital warts.
Typically 70% of HPV infections are cleared within 1 year and 90% are cleared within 2 years

A 33-year-old female patient walks into your office to speak with you about her recent pap smear result. A low-grade squamous intraepithelial lesion was discovered (LSIL). Her most recent pap smear, performed two years ago, came back normal.
Which of the following is the most appropriate course of action?Your Answer: Repeat the pap smear in 6 months
Correct Answer: Repeat the pap smear in one year
Explanation:An LSIL Pap test shows mild cellular changes. The risk of a high-grade cervical precancer or cancer after an LSIL Pap test is as high as 19 percent.
As with an ASC-US Pap test, an LSIL Pap test is evaluated differently depending upon age.
For women ages 25 or older, follow-up depends upon the results of human papillomavirus (HPV) testing:
– Women who test positive for HPV or who have not been tested for HPV should have colposcopy.
– Women who test negative for HPV can be followed up with a Pap test and HPV test in one year.Referring the patient to an oncologist is not acceptable since there is no established diagnosis of malignancy that has been made. All other options are unacceptable since Pap smear must be done in 12 months.

A 27-year-old female G1P1 presents with her husband because she has not been breastfeeding her baby 24 hours though she had previously stated she intended exclusive breastfeeding for the first 3 months. She feels sad most of the time and her mood has been very low for the past 2 weeks, she has trouble sleeping at night and feels tired all day. She complains that her husband doesn’t seem to know how to help. For the past 24 hours she feels like she is not fit to be a mother and doesn’t want to feed the baby anymore. She has been frightened by thoughts to harm herself and the baby. Her baby is 7 weeks old.
In addition to antidepressant medication, which of the following treatment is most appropriate for this patient?Your Answer: Estrogen therapy
Correct Answer: Electroconvulsive therapy
Explanation:This patient presents because of significant mood changes since she gave birth to her child: she is sad most of times and she is having guilt feelings about her adequacy for motherhood- She is also complaining of insomnia, tiredness, and even some suicidal ideation. These symptoms are highly suggestive postpartum depression. This should be differentiated from postpartum blues, which usually present within the first 2 weeks and last for few days. This patient’s symptoms started 5 weeks postpartum. Postpartum depression usually presents within the first 6 weeks to the first year postpartum.
Postpartum depression is the most common complication of childbearing and affects the mother, the child, and relationship with the partner. It is diagnosed the same way as major depressive disorder in other patients. Since untreated postpartum depression can have long-term effects on the mother and the child, appropriate therapy should be undertaken as soon as possible- Antidepressant medications such as sertraline can be used to treat postpartum depression. In a patient who has suicidal ideation, electroconvulsive therapy has a more rapid and effective action than medication and should be considered in these patients.
→ Cognitive behavioural therapy is effective in women with mild to moderate postpartum depression; it would not be a good choice in this patient with suicidal ideation and at risk of harming the baby.
→ Estrogen therapy used alone or in combination with antidepressant, has been shown to significantly reduce the symptoms of postpartum depression; however, it would not be the most appropriate choice in a patient with suicidal ideation.
→ Peer support has shown equivocal results in various studies even though most postpartum patients report that lacking an intimate friend or confidant or facing social isolation are factors leading to depression.
→ Non-directive counselling also known as ”listening visits“ has been found to be effective in postpartum patients, though the studies that were conducted are deemed to be of small sample and larger studies still need to be done to validate these findings. It would not be an appropriate choice for this patient with suicidal ideation. -

What is the most common cause of sepsis in the puerperium?
Your Answer: Soft tissue infection
Correct Answer: Endometritis
Explanation:Significant puerperal pyrexia is defined as a temperature of 38ºC or higher on any two of the first 10 days postpartum, exclusive of the first 24 hours. A mixed flora normally colonizes the vagina with low virulence. Puerperal infection is usually polymicrobial and involves contaminants from the bowel that colonize the perineum and lower genital tract. Following delivery, natural barriers to infection are temporarily removed and therefore organisms with a pathogenic potential can ascend from the lower genital tract into the uterine cavity. Placental separation exposes a large raw area equivalent to an open wound, and retained products of conception and blood clots within the uterus can provide an excellent culture medium for infection.

Regarding the female breast how many lobes does the typical breast contain?
Your Answer: 4
Correct Answer: 15-20
Explanation:The basic components of the mammary gland are the alveoli. These are lined with milk-secreting cuboidal cells surrounded by myoepithelial cells. The alveoli join to form groups known as lobules. The lobules form lobes. Each lobe has a lactiferous duct that drains into openings in the nipple. Each breast typically contains 15-20 lobes.

A 26-year-old woman had a history of dilation and curettage for septic abortion. Currently, she has developed amenorrhea for 6 months already. It was also noted that she smokes 10 cigarettes and drinks 2 standard alcoholic drinks every day. She was tested for beta-hCG but it was not detectable.
Which of the following is considered the most appropriate next step to establish a diagnosis?Your Answer: MRI of the brain
Correct Answer: Transvaginal ultrasound
Explanation:Asherman syndrome (intrauterine adhesions or intrauterine synechiae) occurs when scar tissue forms inside the uterus and/or the cervix. These adhesions occur after surgery of the uterus or after a dilatation and curettage.
Patients with Asherman syndrome may have light or absent menstrual periods (amenorrhea). Some have normal periods based on the surface area of the cavity that is affected. Others have no periods but have severe dysmenorrhea (pain with menstruation).
Although two-dimensional sonography may suggest adhesive disease, Asherman syndrome is more often evaluated initially with saline sonography or hysterosalpingography to demonstrate the adhesions.

An 19-year old female came in at the clinic for her first prenatal visit. She claims to have had regular menstrual cycles even while she was on oral contraceptives (OCP). 20 weeks ago, she stopped taking her OCPs and had a menstrual period few days after. No vaginal bleeding or fluid loss were noted since then. On physical examination, the uterus is palpated right above pubic symphysis. Fetal heartbeats are evident on handheld Doppler ultrasound. Which of the statements can mostly explain the difference between the dates and uterine size?
Your Answer: The foetus is malformed.
Correct Answer: Ovulation did not occur until 6-8 weeks after her last period.
Explanation:When the palpated uterine size is in discrepancy with the expected size based on the duration of amenorrhoea, it can have several causes including reduced fluid volume or fetal growth (both of which are more common when there is fetal malformation), or miscalculated age of gestation as a result of wrong dates or actual ovulation occurring at a later date than expected. Reduced fluid volume and fetal growth are the most likely aetiologies during the third trimester of pregnancy, unlike in this patient at 20 weeks age of gestation.
Premature rupture of membranes is less likely the cause when there is negative vaginal fluid loss like this patient.
The most likely cause in this case is that ovulation did not occur as expected, especially when the patient ceased her OCPs during this period. In some instances, ovulation can occur 2 weeks later in about 50% of women, 6 weeks later in 90%, and may still not occur 12 months later in 1% of women.
The other listed statements are unlikely to explain the discrepancies in dates and the observed uterine size in this patient.

A 29 year old women wants to speak to you regarding infections in pregnancy. Her two year old son has sensorineural deafness as a result of infection in her previous pregnancy. What was the most likely infection?
Your Answer: Rubella
Correct Answer: CMV
Explanation:TORCH infections are responsible for perinatal complications. CMV is the most common amongst them. Primary infection often produces no symptoms or mild non-specific flu-like symptoms in the mother. The diagnosis is often made after abnormalities are seen in the foetus on ultrasound scan. The main features seen in an affected foetus are FGR, microcephaly, ventriculomegaly, ascites or hydrops. Some foetuses which are infected may not show any features on ultrasound, but may later be found to have neurological damage such as blindness, deafness or developmental delay. The neonate can also be anaemic and thrombocytopenic, with hepatosplenomegaly, jaundice and a purpureal rash.

A 29-year-old woman had just delivered a stillborn vaginally, following a major placental abruption. Choose the single most likely predisposing factor for developing PPH in this woman?
Your Answer: DIC
Explanation:Disseminated intravascular coagulation (DIC) in pregnancy is the most common cause of an abnormal haemorrhage tendency during pregnancy and the puerperium. Although pregnancy itself can cause DIC, its presence is invariably evidence of an underlying obstetric disorder such as abruptio placentae, eclampsia, retention of a dead foetus, amniotic fluid embolism, placental retention or bacterial sepsis.

The COCP (Combined Oral Contraceptive Pill) causes all of the following biochemical effects EXCEPT?
Your Answer: Suppress LH
Correct Answer: Elevate FSH
Explanation:COCP’s act both centrally and peripherally. They inhibit ovulation. Both oestrogen and progestogen supress the release of FSH and LH hence preventing ovulation. Peripherally it acts by making the endometrium atrophic and hostile towards implantation. It also alters the cervical mucus and prevents the sperm from ascending the uterine cavity.

A 30-year-old woman at 32 weeks of gestation is discovered to have a positive group B Streptococcus vaginal swab.
Which of the following is considered the most appropriate treatment for the patient?Your Answer: Give trimethoprim for 3 days
Correct Answer: No treatment needed before labour
Explanation:About 1 in 4 pregnant women carry GBS bacteria in their body. Doctors should test pregnant woman for GBS bacteria when they are 36 through 37 weeks pregnant.
Giving pregnant women antibiotics through the vein (IV) during labour can prevent most early-onset GBS disease in newborns. A pregnant woman who tests positive for GBS bacteria and gets antibiotics during labour has only a 1 in 4,000 chance of delivering a baby who will develop GBS disease. If she does not receive antibiotics during labour, her chance of delivering a baby who will develop GBS disease is 1 in 200.
Pregnant women cannot take antibiotics to prevent early-onset GBS disease in newborns before labour. The bacteria can grow back quickly. The antibiotics only help during labour.

A 42 years old woman presents to a gynaecologic clinic with mid-cycle, moderate-intensity abdominal pain. There is also a similar episode of pain around a month ago, which remained for about 3 days and resolved spontaneously. She is otherwise healthy with a normal regular cycle of about 28 days duration.
Examination reveals normal vitals, soft and non-tender abdomen without any guarding or rebound tenderness.
The most likely cause of the patient's problem is?Your Answer: Urinary tract infection
Correct Answer: Ovulation pain
Explanation:This patient has developed symptoms of ovulation discomfort, which is also known as Mittelschmerz syndrome. Lower abdominal and pelvic pain that arises around the middle of a woman’s menstrual cycle characterises this condition.
The discomfort usually appears suddenly and disappears within hours, though it can continue up to three days.The symptoms of ovulation pain can include:
– Lower abdomen pain.
– The pain typically occurs about two weeks before the menstrual period is due.
– The pain is felt on the right or left side, depending on which ovary is releasing an egg.
– The pain may switch from one side to the other from one cycle to the next, or remain on one side for a few cycles.
The duration of pain ranges anywhere from minutes to 48 hours. -

A 27-year-old woman complains of a hard, irregular lump in her right breast that presented after a car accident 2 weeks ago. Which is the most likely diagnosis?
Your Answer: Breast abscess
Correct Answer:
Explanation:Since the car crash happened two weeks prior, breast trauma is suggested and thus fat necrosis is the most probable diagnosis. Phyllodes tumours are typically a firm, palpable mass. These tumours are very fast-growing, and can increase in size in just a few weeks. Occurrence is most common between the ages of 40 and 50, prior to menopause.

A 33-year-old woman presented to the medical clinic with a history of type 2 diabetes mellitus. She plans to conceive in the next few months and asks for advice. Her fasting blood sugar is 10.5 mmol/L and her HbA1c is 9%.
Which of the following is considered the best advice to give to the patient?Your Answer: Start her on insulin and check her blood sugar in 24 hours
Correct Answer: Achieve HbA1c value less than 7% before she gets pregnant
Explanation:Women with diabetes have increased risk for adverse maternal and neonatal outcomes and similar risks are present for either type 1 or type 2 diabetes. Both forms of diabetes require similar intensity of diabetes care. Preconception planning is very important to avoid unintended pregnancies, and to minimize risk of congenital defects. Haemoglobin A1c goal at conception is <6.5% and during pregnancy is <6.0%.

A 27-year-old woman, at 27 weeks of gestation, who lives 40 kilometres from the nearest tertiary obstetric hospital, is referred due to premature rupture of membranes (PROM) which occurred 2 days ago. This is her first pregnancy, which had been progressing normally until the rupture of membranes. Over the last 48 hours, she did not have any contractions. Transfer was made to the tertiary referral obstetric hospital where she was started on glucocorticoid therapy. Cervical swabs were taken and she underwent ultrasound and cardiotocography assessments. She was also started on prophylactic antibiotics. Cervical swabs only showed growth of normal vaginal flora whereas the abdominal ultrasound found almost no liquor. CTG was normal and reactive.
Which is the most appropriate next step in her management?
Your Answer: Prophylactic antibiotic therapy should be continued until delivery occurs.
Correct Answer: The white cell count (WCC) and C-reactive protein (CRP) levels should be assessed every 2-3 days.
Explanation:If a patient presents with PROM at 27 weeks of gestation, her management plan would have to include:
1) Cervical swabs to rule out infection
2) Commencement of prophylactic antibiotics such as erythromycin until results from the swabs are available
-If only normal vaginal flora are seen, prophylactic antibiotics can be stopped.
3) Administration of glucocorticoid- usually for 48 hours to promote maturity of the fetal lung and lower the chance of intracranial bleeding if the foetus has to be delivered prematurely
4) Transfer to a healthcare centre that has neonatal intensive care facilities to ensure if intensive care is needed post-delivery, the healthcare staff are prepared
5) Blood profile (particularly white cell count) and inflammatory markers (CRP) to look for any signs of chorioamnionitis
6) CTG assessment every 2-3 days. Abnormalities found on the CTG tracing are often the first evidence of problems such as a subclinical chorioamnionitis
7) Tocolysis with tocolytics such as IV salbutamol or nifedipine if contractions start before the course of glucocorticoid therapy is finished. Post-glucocorticoid therapy, tocolysis would not be often employed since there is a risk of masking contractions that occur due to an infection. In those cases, it is better to deliver the baby rather than to prolong the pregnancy. If there is no infection, the management plan should aim to prolong the pregnancy and delay delivery of a very premature baby. -

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 to women with vasomotor symptoms, while they are still menstruating, is likely to increase the incidence of AD in the future.
Correct 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. -

Regarding feto-maternal blood circulation, which of the following statements is false?
Your Answer: In the umbilical vein the pressure is approximately 20 mmHg
Correct Answer: At term the placenta receives 70% of uterine blood flow
Explanation:The placenta is important for regulating feto-maternal blood circulation, ensuring that the two circulatory systems do not come into direct contact. The placenta receives 70-80% of the uterine blood flow into the decidual spiral arteries where nutrient, waste and gaseous exchange with fetal blood takes place via the villous core fetal vessels. Deoxygenated blood arrives at the placenta via two uterine arteries while oxygenated, nutrient-rich blood is circulated back to the foetus via a single umbilical vein. The pressure in the umbilical vein is about 20 mmHg.

Which of the following is the primary host for Toxoplasma Gondii?
Your Answer: Cats
Explanation:Toxoplasma gondii, an intracellular protozoan, is the main causative agent for Toxoplasmosis. The primary host for the organism is the domestic cat. Humans can become infected by eating undercooked meat of animals harbouring cysts, consuming water or food contaminated with cat faeces, or through maternal-fetal transmission. Toxoplasmosis can cause complications in pregnancy such as miscarriages and congenital infection can lead to hydrocephalus, microcephaly, mental disability and vision loss.

Menstrual irregularities and hirsutism affect a 15-year-old girl. All of the syndromes listed below have been linked to obesity in children.
Select the syndrome with which the other clinical symptoms in this patient are most likely to be linked.Your Answer: Cushing syndrome
Correct Answer: Polycystic ovary syndrome
Explanation:Polycystic ovary syndrome (PCOS) is a condition in which the ovaries produce an abnormal amount of androgens, male sex hormones that are usually present in women in small amounts. The name polycystic ovary syndrome describes the numerous small cysts (fluid-filled sacs) that form in the ovaries. However, some women with this disorder do not have cysts, while some women without the disorder do develop cysts.
The symptoms of PCOS may include:
– Missed periods, irregular periods, or very light periods
– Ovaries that are large or have many cysts
– Excess body hair, including the chest, stomach, and back (hirsutism)
– Weight gain, especially around the belly (abdomen)
– Acne or oily skin
– Male-pattern baldness or thinning hair
– Infertility
– Small pieces of excess skin on the neck or armpits (skin tags)
– Dark or thick skin patches on the back of the neck, in the armpits, and under the breastsThe so-called Laurence-Moon-Biedl syndrome is a fairly rare condition characterized by six cardinal signs, namely obesity, atypical retinitis pigmentosa, mental deficiency, genital dystrophy, polydactylism and familial occurrence.
Froehlich syndrome is characterized by increased or excessive eating that leads to obesity, small testes, and a delay in the onset of puberty. It is also common for children with Froehlich syndrome to experience the delay in physical growth and the development of secondary sexual characteristics.
Cushing’s syndrome is a disorder that occurs when your body makes too much of the hormone cortisol over a long period of time. Cortisol is sometimes called the “stress hormone” because it helps your body respond to stress. Cortisol also helps. maintain blood pressure. regulate blood glucose, also called blood sugar.
Pseudohypoparathyroidism is characterized by short stature, a round face, short neck, and shortened bones in the hands and feet. Intelligence usually ranges from low normal to mentally retarded. Headaches, weakness, tiring easily, lethargy, cataracts and blurred vision or hypersensitivity to light may also be present.
This patient’s condition can only be explained by PCOS. -

A 27-year-old woman with primary infertility presents with secondary amenorrhoea that has been ongoing for twelve months. She states that she has been thinking about starting a family and was wondering if ovulation induction therapy was an option for her.
Which one of the following would be most valuable in predicting a poor response to ovulation induction therapy?Your Answer: Serum prolactin.
Correct Answer: Serum follicle-stimulating hormone (FSH).
Explanation:The tests listed can all be performed during the work-up of a woman with secondary amenorrhoea. They are useful in that they cam diagnosis the most likely cause for the amenorrhoea as well as guide the treatment required if the patient wanted to become pregnant. Of these, the hormone test best able to predict a poor response to ovulation-induction therapy is the follicle-stimulating hormone (FSH) assay. If there are high levels of FSH, most of the ovulation-induction therapies are ineffective, although the rare spontaneous pregnancy can occur.
To maximise the chance of pregnancy in patients with elevated FSH levels, the most effective technique is an ovum donation from a young woman. The ovum would be fertilised in the laboratory and transferred to the uterus of the woman with the high FSH level after administering hormonal preparation of her uterus.
If the FSH level is normal, ovulation-induction therapy is usually effective. For these patients, correction of thyroid function will be necessary if the thyroid function is not normal. Dopamine agonist therapy is indicated if the prolactin level is elevated. Clomiphene or gonadotrophin therapy can be used where the luteinising and oestradiol levels are low, normal, or minimally elevated.

A 30-year-old woman is already in her second pregnancy and is 22 weeks pregnant. She presented to the medical clinic for evaluation of a vulval ulcer. A swab was taken and revealed a diagnosis of herpes simplex type II (HSV-2) infection. She was surprised about this diagnosis since neither she nor her husband has ever had this infection before. She insisted on knowing the source of the infection and was very concerned about her baby’s well-being and she asked how her condition may affect the baby.
Which of the following statements is considered true regarding her situation?Your Answer: The primary infection is commonly asymptomatic
Explanation:Genital herpes can be asymptomatic or have mild symptoms that go unrecognized. When symptoms occur, genital herpes is characterised by one or more genital or anal blisters or ulcers. Additionally, symptoms of a new infection often include fever, body aches and swollen lymph nodes.
HSV-2 is mainly transmitted during sex through contact with genital or anal surfaces, skin, sores or fluids of someone infected with the virus. HSV-2 can be transmitted even if the skin looks normal and is often transmitted in the absence of symptoms.
In rare circumstances, herpes (HSV-1 and HSV-2) can be transmitted from mother to child during delivery, causing neonatal herpes. Neonatal herpes can occur when an infant is exposed to HSV during delivery. Neonatal herpes is rare, occurring in an estimated 10 out of every 100 000 births globally. However, it is a serious condition that can lead to lasting neurologic disability or death. The risk for neonatal herpes is greatest when a mother acquires HSV for the first time in late pregnancy.

A 40-year-old woman arrives at the hospital at eight weeks of her first pregnancy, anxious that her kid may have Down syndrome. Which of the following best reflects the risk of spontaneous abortion after an amniocentesis performed at 16 weeks?
Your Answer: 39%
Correct Answer: 18%
Explanation:This question assesses critical clinical knowledge, as this information must be presented to a patient prior to an amniocentesis to ensure that she has given her informed permission for the treatment.
Amniocentesis is most typically used for genetic counselling in the second trimester of pregnancy. Another option is to do a chorion-villus biopsy (CVB) between 10 and 11 weeks of pregnancy.
The chances of miscarriage after both operations are roughly 1 in 200 for amniocentesis and 1 in 100 for CVB, according to most experts.
The significance of this question is that professionals must be able to weigh the procedure’s danger against the risk of the sickness they are trying to identify. -

A 51-year-old woman comes to your doctor's office for a breast cancer screening. For the past year, she has been on combination hormone replacement treatment (HRT). Mammography is the sole accessible form of breast cancer screening, and she is predicted to have dense breast tissue due to HRT.
Which of the following is the best HRT and breast cancer screening suggestion for this patient?Your Answer: Change combined HRT to oestrogen-only hormone replacement therapy
Correct Answer: Continue HRT and perform mammography as recommended for other women
Explanation:Among a variety of imaging modalities developed for breast cancer screening, mammography is the best-studied and the only imaging technique that has been shown to decrease mortality as demonstrated in multiple randomized trials. However, it is important to know that, even in the best circumstances, mammography may miss up to 20 percent of underlying breast cancers.
Women on HRT are likely to have dense breast. Dense breasts are associated with an increased risk of breast cancer and can decrease the sensitivity of mammography for small lesions. Nevertheless, we do not alter our general approach to age- and risk-based screening based on breast density. However, for women with dense breasts, we do prefer digital mammography over film mammography, due to greater sensitivity; digital mammography is the modality typically used for mammography in most locations in the United States.

Which of the following statements is true regarding management of caesarean section?
Your Answer: Co-amoxiclav 1.2g IV should be given prior to skin incision
Correct Answer: Uterine closure can be in 1 or 2 layers
Explanation:Closure of the uterus should be performed in either single or double layers with continuous or interrupted sutures. The initial suture should be placed just lateral to the incision angle, and the closure continued to a point just lateral to the angle on the opposite side. A running stitch is often employed and this may be locked to improve haemostasis. If a second layer is used, an inverting suture or horizontal suture should overlap the myometrium. Once repaired, the incision is assessed for haemostasis and ‘figure-of-eight’
sutures can be employed to control bleeding. Peritoneal closure is unnecessary. Abdominal closure is performed in the anatomical planes with high strength, low reactivity materials, such as polyglycolic acid or polyglactin. Diamorphine is advised for intra and post op analgesia and oxytocin is advised to reduce blood loss. -

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

A 34 year old female presents to the ob-gyn for a regular antenatal visit. Her previous pregnancy was complicated by pre-eclampsia and later eclampsia. What are the chances of her pre-eclampsia recurring in a later pregnancy?
Your Answer: There is no increase in risk above the normal population level.
Correct Answer:
Explanation:Research suggests the risk of having preeclampsia again is approximately 20%, however experts cite a range from 5% to 80% depending on when you had it in a prior pregnancy, how severe it was, and additional risk factors you may have. If you had preeclampsia during your first pregnancy, you may get it again. HELLP is related to preeclampsia and about 4 to 12 percent of women diagnosed with preeclampsia develop HELLP. HELLP syndrome can also cause complications in pregnancy, and if you had HELLP in a previous pregnancy, regardless of the time of onset, you have a greater risk for developing it in future pregnancies.

A 19-year-old female books an appointment at the antenatal clinic at 13 weeks gestation.
One week ago, she had a Papanicolaou (Pap) smear done which showed grade 3 cervical intraepithelial neoplasia (CIN3).
What is the best next step in her management?Your Answer: Colposcopy and large loop excision of the transformation zone (LLETZ biopsy).
Correct Answer: Colposcopy.
Explanation:The best next step in her management is a colposcopy.
Patients diagnosed with high-grade lesions (CIN 2 or 3) or adenocarcinoma in situ (AIS) during pregnancy should undergo surveillance via colposcopy and age-based testing (cytology/HPV) every 12-24 weeks.
Cone biopsy and long loop excision of the transformation zone (LLETZ biopsy) are not recommended if the lesion extends up the canal and out of the vision of the colposcope.
It is not necessary to terminate the pregnancy.Because repeat colposcopic examination during pregnancy offers all of the information needed, the repeat Pap smear is best done after the pregnancy has ended.
Unless colposcopy indicates aggressive cancer at an earlier time, the ultimate therapy required is usually not decided until the postpartum visit.

A 50-year-old woman comes to the clinic complaining she is “urinating all the time. It started initially as some leakage of urine with sneezing or coughing, but now she leaks while walking to the bathroom. She voids frequently during the day and several times each night, also sometimes patient feels an intense urge to urinate but passes only a small amount when she tries to void. She now wears a pad every day and plans her social outings based on bathroom access. Patient had no history of dysuria or hematuria and had 2 vaginal deliveries in her 20s. She drinks alcohol socially, takes 2 or 3 cups of coffee each morning, and “drinks lots of water throughout the day.” When asked about which urinary symptoms are the most troublesome, the patient is unsure.
Among the following which is the best next step in management of this patient?Your Answer: Voiding diary
Explanation:This patient experiences a stress based mixed urinary incontinence presented as leakage of urine while sneezing or coughing and urgency which is an intense urge to urinate with small voiding volume as her symptoms. Urinary incontinence is common and may cause significant distress in some, as seen in this patient who wears a pad every day. Initial evaluation of mixed incontinence includes maintaining a voiding diary, which helps to classify the predominant type of urinary incontinence and thereby to determine an optimal treatment by tracking the fluid intake, urine output and leaking episodes.
All patients with mixed incontinence generally require bladder training along with lifestyle changes like weight loss, smoking cessation, decreased alcohol and caffeine intake and practicing pelvic floor muscle exercises like Kegels. Depending on the predominant type, patients who have limited or incomplete symptom relief with bladder training may benefit from pharmacotherapy or surgery.
In patients with urgency-predominant incontinence, timed voiding practice like urinating on a fixed schedule rather than based on a sense of urgency along with oral antimuscarinics are found to be useful.
Surgery with a mid-urethral sling is performed in patients with stress-predominant incontinence which is due to a weakened pelvic floor muscles as in cystocele.
In patients with a suspected urethral diverticulum or vesicovaginal fistula, a cystoscopy is usually indicated but is not used in initial evaluation of urinary incontinence due to its cost and invasiveness.
Urodynamic testing involves measurement of bladder filling and emptying called as cystometry, urine flow, and pressure (eg, urethral leak point). This testing is typically reserved for those patients with complicated urinary incontinence, who will not respond to treatment or to those who are considering surgical intervention.
Initial evaluation of mixed urinary incontinence is done by maintaining a voiding diary, which helps to classify predominant type of urinary incontinence into stress predominant or urgency predominant and thereby to determine the optimal treatment required like bladder training, surgical intervention, etc.

A 30 year old female with type I diabetes for 13 years, came for pre-pregnancy counselling. Which of the following is the most suitable advise for her?
Your Answer: She should aim to have a pre-pregnancy HbA1c of <48 mmol/mol (6.5%)
Correct Answer:
Explanation:According to NICE guidelines women with type I diabetes, who are expecting a child should aim to keep their HbA1c level[1] below 48 mmol/mol (6.5%) without causing problematic hypoglycaemia. Women with diabetes whose HbA1c level is above 86 mmol/mol (10%) should be strongly advised not to get pregnant because of the associated risks. The risks are higher with chronic diabetes. There is an increased risk to the foetus or mother due to diabetes in pregnancy. Women who are waiting to become pregnant should take folic acid (5 mg/day) until 12 weeks of gestation to reduce the risk of having a baby with a neural tube defect.

Which structure reinforces the inguinal canal anterolaterally?
Your Answer: Conjoint tendon
Correct Answer: Internal oblique
Explanation:The anatomy of the inguinal canal is of surgical importance. In the male, the inguinal canal carries the spermatic cord, ilioinguinal nerve and important blood vessels, while in females the inguinal canal holds the round ligament, ilioinguinal nerve and blood vessels. The floor of the inguinal canal is made of the inguinal ligament (a thickened portion of the inguinal ligament), while the posterior wall is made of the transversalis muscle. The anterior wall is made of the external oblique aponeurosis, and the roof is made up of fibres of the internal oblique, transversus abdominis and its aponeurosis, and the conjoint tendon. This means that the anterolateral support structure of the inguinal canal would be the fibres of the internal oblique.

A 35-year-old female patient, gravida 1 para 1, visits the clinic to have her contraception method evaluated. The patient has had unpredictable bleeding for the past 8 months since receiving a subdermal progestin implant and begs that it be removed. She used to use combined oral contraceptives and would like to go back to it. The patient has primary hypertension, which she was diagnosed with last year and is effectively controlled on hydrochlorothiazide. She does not take any other medications or have any allergies. Her father and brother both suffer from type 2 diabetes. The patient does not smoke, drink, or use illegal drugs.
24 kg/m2 is her BMI. Blood pressure is 130/75 millimetres of mercury. Physical examinations are all normal. Which of the following is increased by using combination oral contraceptives?Your Answer: Type 2 diabetes mellitus
Correct Answer: Worsening hypertension
Explanation:Overt hypertension, developing in about 5% of Pill users, and increases in blood pressure (but within normal limits) in many more is believed to be the result of changes in the renin-angiotensin-aldosterone system, particularly a consistent and marked increase in the plasma renin substrate concentrations. The mechanisms for the hypertensive response are unclear since normal women may demonstrate marked changes in the renin system. A failure of the kidneys to fully suppress renal renin secretion could thus be an important predisposing factor. These observations provide guidelines for the prescription of oral contraceptives. A baseline blood pressure measurement should be obtained, and blood pressure and weight should be followed at 2- or 3-month intervals during treatment. Oral contraceptive therapy should be contraindicated for individuals with a history of hypertension, renal disease, toxaemia, or fluid retention. A positive family history of hypertension, women for whom long-term therapy is indicated, and groups such as blacks, especially prone to hypertensive phenomena, are all relative contraindications for the Pill.

A 17-year-old girl presented to the medical clinic for emergency contraception. Upon interview, it was revealed that she had unprotected sexual intercourse last night and is worried that she may become pregnant. She mentioned that her last menstrual period was 1 week ago, and she has regular menses since menarche.
Further physical examination was performed and results are normal and her urine pregnancy test is negative. After discussing various emergency contraceptive options, the patient asked for a pill option and requested to not inform her parents about this visit.
In most states, which of the following is considered the most appropriate step in managing this patient?Your Answer: Prescribe misoprostol (prostaglandin E1) pills
Correct Answer: Provide levonorgestrel pill
Explanation:Levonorgestrel, also known as the morning-after pill, is a first-line oral emergency contraceptive pill with approval from the World Health Organization to prevent pregnancy. It is FDA-approved to be used within 72 hours of unprotected sexual intercourse or when a presumed contraceptive failure has occurred.
A prescription is not needed, and it is available over the counter at local pharmacies. The FDA has also approved levonorgestrel availability for all age groups due to its lack of life-threatening contraindications and side-effect profile.
There are several contraindications for the emergency contraceptive form, including allergy, hypersensitivity, severe liver disease, pregnancy, and drug-drug interactions with liver enzyme-inducing drugs. The medication is not for use in women confirmed to be pregnant; however, there is no proof nor reports of adverse effects on the mother or foetus following inadvertent exposure during pregnancy.

A 23 year old female patient with DVT on anticoagulant came to your clinic for advice. She is on combined OCPs.
What would you advice her?Your Answer: Prescribe oestrogen patch
Correct Answer: Progesterone only pill
Explanation:Women with medical conditions associated with increased risk for thrombosis generally should not use oestrogen-containing contraceptives.
The majority of evidence identified does not suggest an increase in odds for venous or arterial events with use of most POCs. Limited evidence suggested increased odds of VTE with use of injectables (three studies) and use of POCs for therapeutic indications (two studies, one with POCs unspecified and the other with POPs).
Discontinuing anticoagulants increases her risk of recurrent DVT.

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: Endometrial ablation.
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.

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: 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 patient with amenorrhoea is seen in clinic. History and examination reveal the patient runs 10-20 miles every day and her BMI is 17.8. Which of the following is likely to explain her symptoms?
Your Answer: WHO type III Ovulation Disorders
Correct Answer: WHO type I Ovulation Disorders
Explanation:World Health Organization (WHO) Group I ovulation disorder is due to hypothalamic pituitary failure. This is sometimes termed hypothalamic amenorrhoea or hypogonadotropic hypogonadism. Women can improve frequency of ovulation, conception and an uncomplicated pregnancy by increasing their body weight (if BMI of <19) and/or moderating their exercise levels (if they undertake high levels of exercise). GnRH and LH may be administered in these patients. PCOS falls under type II ovulation disorders. WHO Group III ovulation disorder is due to ovarian failure.

A 23-year-old woman presents to the local hospital clinic for her first antenatal visit.
She is primigravid at 39 weeks of gestation (exact dates uncertain).
She has just arrived from overseas, and no antenatal care had been available in her origin country.
On examination, BP is 120/80 mmHg. The fundal height is 30cm above the pubic symphysis. Fetal heart sounds are present at a rate of 144/min.
Pelvic examination indicates a long, closed cervix. The baby is noted to be in cephalic presentation.
What is the appropriate choice for initial management of this woman?Your Answer: Fetal kick chart.
Correct Answer: Ultrasound examination.
Explanation:In this case, the fundus height appears to be smaller than the suggested dates of gestation. However, this is uncertain as the exact gestation dates are not known. Head-sparing intrauterine growth restriction needs to be excluded or managed appropriately if detected.
The best initial management step would be to perform an ultrasound examination (correct answer). This would enable complete assessment of the foetus and all the measurable parameters can be determined. This would aid in identifying any discrepancy in size of the abdomen, limbs and head, and the liquor volume (amniotic fluid index) could be evaluated.
If asymmetrical growth restriction was detected via ultrasound examination, further evaluations such as cardiotocography (CTG) and umbilical arterial wave form analysis by Doppler could be initiated.
Additionally, foetal movement counting could then be commenced and evaluation of foetal lung maturity by amniocentesis could be considered.
If the ultrasound was normal (no evidence of asymmetrical growth restriction, normal amniotic fluid), repeat ultrasound should be performed after two weeks to evaluate the foetal growth.
If normal growth is observed on the repeat ultrasound, the estimated due date can be calculated (assuming normal foetal growth around the 50th percentile for the population).

A 24 year old lady is 9 weeks pregnant with her first child. She attends clinic complaining of severe vomiting and is unable to keep fluids down. The most likely diagnosis is hyperemesis gravidarum. Which of the following is the underlying cause?
Your Answer: Decreased circulating dopamine
Correct Answer: Increased circulating HCG
Explanation:Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy, associated with weight loss of more than 5% of pre-pregnancy weight, dehydration and electrolyte imbalance. HG is usually most severe during the first 12 weeks of pregnancy and is thought to be caused by high circulating levels of HCG.
There is not yet any evidence that pregnancy itself increases the sensitivity of the area postrema, or that the hormones, oestradiol, or progesterone increase vomiting. Generally, higher concentrations of dopamine stimulates receptors in the chemoreceptor trigger zone leading to nausea and vomiting. Although this has not been demonstrated as the cause of hyperemesis gravidarum.

Which of the following terms best describes the pelvic type of small posterior sagittal diameter, convergent sidewalls, prominent ischial spines, and narrow pubic arch?
Your Answer: Android
Explanation:There are four types pelvic shapes:
1) Android pelvis: it has a larger inlet and smaller outlet along with small posterior sagittal diameter, prominent ischial spines and has a two finger arch.
2) Gynecoid pelvis: it has a transverse or nearly a circular ellipse and it is the most favourable for delivery.
3) Anthropoid pelvis: the brim is an anteroposterior ellipse.
4) Platypelloid pelvis: in this type the pelvic brim is kidney shape -
