A young couple visited your clinic for taking your opinion. The woman has a history of rheumatoid arthritis, and is on methotrexate and sulfasalazine; and they are planning to have a baby in next three months.
What will be the most appropriate management in this patient during her pregnancy?Your Answer: Stop methotrexate and continue sulfasalazine
Explanation:Rheumatoid arthritis and its prognosis during pregnancy are highly unpredictable, as the disease can improve in 75% of the cases and gets worse in 25%. During conception and pregnancy, it is advisable to avoid those rheumatoid arthritis medications which possess high risk in causing congenital disabilities. Most common such contraindicated remedies include methotrexate and leflunomide.
Drugs like Prednisone, Non-steroidal anti-inflammatory drugs and TNF inhibitors are also not considered safe during pregnancy, so if required these should be used under specialist supervision.Sulfasalazine and Antimalarials such as hydroxychloroquine are safe and can be used without much complications during pregnancy. In this given case, the patient should be advised to stop methotrexate and to continue sulfasalazine during pregnancy.

A 53 year old female presents with hot flushes and night sweats. Her last menstrual period was last year. She had MI recently. Choose the most appropriate management for this patient.
Your Answer: Evening primrose
Correct Answer: Clonidine
Explanation:With a history of MI, oestrogen and COCP should be avoided. Evening primrose is also not suitable for post-menopausal symptoms. Raloxifene is a SERM – these make hot flushes worse. Clonidine will help improve the hot flushes and the vasomotor symptoms.

Which increases the risk for developing endometrial cancer?
Your Answer: Early menarche
Explanation:Endometrioid endometrial carcinoma is oestrogen-responsive, and the main risk factor for this disease is long-term exposure to excess endogenous or exogenous oestrogen without adequate opposition by a progestin.
Early age at menarche is a risk factor for endometrial carcinoma in some studies; late menopause is less consistently associated with an increased risk of the disease. Both of these factors result in prolonged oestrogen stimulation and at times of the reproductive years during which anovulatory cycles are common
Other risk factors include
obesity,
nulliparity,
diabetes mellitus, and
hypertension.The risk of endometrial hyperplasia and carcinoma with oestrogen therapy can be significantly reduced by the concomitant administration of a progestin. In general, combined oestrogen-progestin preparations do not increase the risk of endometrial hyperplasia.
Endometrial carcinoma usually occurs in postmenopausal women (mean age at diagnosis is 62 years). Women under age 50 who develop endometrial cancer often have risk factors such as obesity or chronic anovulation.

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: Starting HRT in a woman who clearly has advanced AD is of value in reducing the severity of the disease.
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. -

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

Examination of endometrial tissue obtained from a biopsy reveals simple columnar epithelium with no sub-nuclear vacuoles. The stroma is oedematous, & a tortuous gland contains secretions. These findings are consistent with which stage of the menstrual cycle?
Your Answer: Mid-secretory
Explanation:During mid secretory phase, the endometrium cells undergo distension, become more tortuous and are lined by columnar cells.
In the early proliferative phase, the glandular epithelium is cubo-columnar, while in the late proliferative phase, the glands increase in size, becoming tortuous and there is pseudostratification of the epithelium. -

A 34-year-old woman, known to have had a history of mild pulmonary hypertension, was admitted to the labour ward. She is at 36 weeks of pregnancy and is keen to have her baby delivered via caesarean section.
Which of the following is the most appropriate advice to give to the patient given her situation?Your Answer: Caesarean section
Explanation:Pulmonary hypertension (PH) is an increase of blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, leading to shortness of breath, dizziness, fainting, and other symptoms, all of which are exacerbated by exertion. PH in pregnancy carries a 25–56% maternal mortality rate with a mixture of intrapartum and postpartum deaths.
Current recommendations for management of PH in pregnancy include termination of pregnancy if diagnosed early, or utilizing a controlled interventional approach with early nebulized prostanoid therapy and early elective caesarean section under regional anaesthesia. Other recommended therapies for peripartum management of PH include sildenafil and nitric oxide.

DEXA scans measure bone density by
Your Answer: Measuring absorption from two different XRAY beams with different energy peaks at the same site
Explanation:DEXA works by passing two low dose XRAY beams with different energy peaks at the patient’s bone. Some of the XRAY radiation will be absorbed (the greater the density the greater the absorption) whilst some will pass through to a detector. Soft tissue absorption is subtracted out and the BMD can be determined from the absorption of each beam. It is important to realise that two beams are used at each site when measuring bone density (hence ‘dual’). Although two sites are typically used (spine and femoral neck) when measuring bone density this is not why the term dual is used Computer analysis of multiple X-ray beams taken from different angles and geographical digital processing are features of CT scanning

A 65-year-old female patient complained of two months of painless vaginal bleeding. The endometrial thickness is 6mm, according to transvaginal ultrasound. To rule out endometrial cancer, you plan to send this patient to a gynaecologist for an endometrial biopsy with or without hysteroscopy.
Which of the following characteristics in your medical history is linked to a higher risk of endometrial cancer?Your Answer: Regular ovulatory periods
Correct Answer: Polycystic ovary syndrome associated with chronic anovulation
Explanation:Women with polycystic ovary syndrome (PCOS) have a 2.7-fold increased risk for developing endometrial cancer. A major factor for this increased malignancy risk is prolonged exposure of the endometrium to unopposed oestrogen that results from anovulation.
Additionally, secretory endometrium of some women with PCOS undergoing ovulation induction or receiving exogenous progestin exhibits progesterone resistance accompanied by dysregulation of gene expression controlling steroid action and cell proliferation.
Other risk factors include nulliparity, early menarche and late menopause, obesity and family history of endometrial cancer. Which rules out all the other options.

A 25 year old female patient comes in the first trimester of her pregnancy. Pap smear reveals that she has HSIL. What is the next best step in management?
Your Answer: Colposcopy
Explanation:Pregnant women with high-grade squamous intraepithelial lesions (HSIL) on cervical cytology should be evaluated with colposcopy. Principles of management of pregnant women include the following:
– An immediate diagnostic excisional procedure should NOT be performed.
– When colposcopy is performed during pregnancy:
– Endocervical sampling with a curette and endometrial sampling should NOT be performed, as there is a risk of disturbing the pregnancy; however, the endocervical canal may be sampled gently with a cytobrush.
– Cervical biopsy should be performed only if a lesion is present that appears to be high grade or suspicious for cancer.
– If the examination is unsatisfactory, repeating the colposcopy after 6 to 12 weeks should allow visualization of the entire squamocolumnar junction.There is no indication for inducing abortion or performing a hysterectomy.

Oxytocin causes increased myometrial contractions via which of the following messenger pathways?
Your Answer: Releases cAMP that triggers intracellular Calcium ion release
Correct Answer: Activates phospholipase-C which produces IP3 which triggers intracellular Calcium ion release
Explanation:Oxytocin activates phospholipase C to produce inositol 1,4,5-trisphosphate (IP3), which releases Ca2+ from intracellular stores. There are thought to be other mechanisms by which myometrium is stimulated by Oxytocin including increased sensitisation of the myometrium and increased calcium entry into cells. cAMP and Protein Kinase A inhibit myometrial contractility.

A 66-year-old lady comes to your clinic complaining of a brownish vaginal discharge that has been bothering her for the previous three months. Atrophic vagina is seen on inspection.
Which of the following diagnoses is the most likely?Your Answer: Vaginal atrophy
Explanation:Endometrial cancer should always be the first diagnosis to rule out in a 65-year-old lady with brownish vaginal discharge. The inquiry focuses on the most likely source of the symptoms, rather than the most significant diagnosis to explore.
Blood typically causes the dark hue of vaginal discharge. The uterine cavity or the vagina can both be the source of bleeding. Only 5-10% of postmenopausal women with vaginal bleeding were found to have endometrial cancer. Around 60% of the women had atrophic vaginitis.Urogenital atrophy is caused by oestrogen insufficiency in postmenopausal women. Urogenital atrophy can cause the following symptoms:
– Dry vaginal skin
– Vaginal inflammation or burning
– Vaginal lubrication is reduced during sexual activity.
– Vulvar or vaginal pain, as well as dyspareunia (at the introitus or within the vagina)
– Vaginal or vulvar bleeding (e.g. postcoital bleeding. fissures)
– Vaginal discharge from the cervix (leukorrhea or yellow and malodorous)
– A vaginal bulge or pelvic pressure
– Symptoms of the urinary tract (e.g. urinary frequency, dysuria, urethral discomfort, haematuria). -

Question 30
Incorrect
-
Which one of the following has the most significant effect on slowing drug metabolism in pregnancy?
Your Answer: Lower albumin concentration
Correct Answer: Progesterone effect on gastric motility
Explanation:Progesterone down regulates gastric motility meaning drugs are absorbed and metabolised more slowly, thus drugs are absorbed, metabolised and cleared more slowly. Most of the drugs are transported after binding to the albumin.
Lower albumin levels mean a greater unbound drug fraction but as this may be thought to increase drug concentrations it actually leaves more available for hepatic clearance or renal excretion so overall drug concentrations are unchanged and metabolism increased.
Increase in hepatic flow will increase the metabolism of the drug as the drug will be transported faster.
Increased renal blood flow will result in the faster clearance of the drug from the body. -

A 36-year-old woman is being tested for a breast tumour she discovered last week during a routine physical examination. Two years ago, the patient had bilateral reduction mammoplasty for breast hyperplasia. Her paternal grandmother died of breast cancer at the age of 65, thus she doesn't take any drugs or have any allergies.
A fixed lump in the upper outer quadrant of the right breast is palpated during a breast examination. In the upper outer quadrant of the right breast, mammography reveals a 3 × 3-cm spiculated tumour with coarse calcifications. A hyperechoic mass can be seen on ultrasonography of the breast. The mass is removed with concordant pathologic findings, and a core biopsy reveals foamy macrophages and fat globules.
Which of the following is the best plan of action for this patient's management?Your Answer: Reassurance and routine follow-up
Explanation:Fat necrosis is a benign (non-cancerous) breast condition that can develop when an area of fatty breast tissue is injured. It can also develop after breast surgery or radiation treatment.
There are different stages of fat necrosis. As the fat cells die, they release their contents, forming a sac-like collection of greasy fluid called an oil cyst. Over time, calcifications (small deposits of calcium) can form around the walls of the cyst, which can often be seen on mammograms. As the body continues to repair the damaged breast tissue, it’s usually replaced by denser scar tissue. Oil cysts and areas of fat necrosis can form a lump that can be felt, but it usually doesn’t hurt. The skin around the lump might look thicker, red, or bruised. Sometimes these changes can be hard to tell apart from cancers on a breast exam or even a mammogram. If this is the case, a breast biopsy (removing all or part of the lump to look at the tissue under the microscope) might be needed to find out if the lump contains cancer cells. These breast changes do not affect your risk for breast cancer.
Mastectomy, axillary node dissection and radiation therapy are all management options for malignancy which this patient doesn’t have.

A 36-year-old obese woman presents to your office for advice regarding pregnancy.
Her body mass index is 40, and she is normotensive and has a normal serum glucose level. On examination she was tested positive for glucose in urine.
What would be your advice to her?Your Answer: She will be checked for pre-existing diabetes in early pregnancy and, for gestational diabetes at 26 weeks
Explanation:Counselling her about the risks associated with obesity during pregnancy will be the best possible advice to give this patient. A combined follow up by an obstetrician and a diabetes specialist at a high-risk pregnancy clinic is required to formulate the best ways in management of gestation with obesity.
An oral glucose tolerance test should be done at 26 weeks of her pregnancy, along with advising her on controlling her weight by diet and lifestyle modifications. During the early weeks of their pregnancy all obese patients must be routinely tested for pre-existing diabetes.It is highly inappropriate to advice her not to get pregnant.
Without making a proper diagnosis of diabetes, it is wrong to ask her to start oral hypoglycemic agent and/or insulin.
Checking urinary proteins is not indicated at this stage, but can be considered as a part of antenatal check up.

A 26 year old patient with a past medical history of 2 terminations of pregnancies over the past 2 years, presents to the emergency centre complaining of severe abdominal pain and some vaginal bleeding. She has a regular 28 day cycle, and is on an oral contraceptive pill, but missed last month's period. Her last termination was over 6 months ago. She smokes almost a pack of cigarettes a day.
Which of the following is the most likely diagnosis?Your Answer: Ectopic pregnancy
Explanation:The clinical picture demonstrated is most likely that of a ruptured ectopic pregnancy. The period of amenorrhea may point to pregnancy, while the past medical history of 2 recent terminations of pregnancy may indicate a failure of her current contraceptive method. Smoking cigarettes have been shown to not only decrease the efficacy of OCPs, but also serve as a known risk factor for ectopic pregnancy. The lady is unlikely to have endometritis as her last termination was over 6 months ago. The lack of fever helps to make appendicitis, PID and pyelonephritis less likely, though they are still possible.

A 20-year-old nulligravid woman comes to the office for a routine checkup, as she is concerned about having gained 4.5 kg over the last year. She believes that the gain is related to her oral contraceptive pills.
Patient takes low-dose ethinyl estradiol
orethindrone daily. Prior to starting the pills, she had regular but heavy periods lasting for 4-5 days. Patient used to miss her school every month, on the first day of her period, due to severe cramping. Her pain symptoms resolved 3 months after starting the pills and she takes no other medications. Patient's coitarche was at the age of 18 and she has had 2 partners since then. Patient and her current partner use condoms inconsistently.
On examination her vital signs are normal, with a BMI of 27 kg/m2 and physical examination is unremarkable.
Among the following which is the most appropriate advice for this patient?Your Answer: Reassure that the weight gain is not related to combined OCPs
Explanation:Breakthrough bleeding, breast tenderness, nausea, bloating, amenorrhea, hypertension, venous thromboembolic disease, increased risk of cervical cancer with decreased risk of ovarian & endometrial cancer, liver disorders like hepatic adenoma and increase in triglycerides due to estrogen component are the common side effects & risks of using combination oral contraceptives.
Patient in the given case mentioned symptoms of primary dysmenorrhea, which is recurrent lower abdominal pain associated with menstruation. Combination estrogen-progestin oral contraceptive pills (OCPs) are considered as the first-line treatment for dysmenorrhea in sexually active patients as OCPs help to reduce pain by thinning the endometrial lining, reducing prostaglandin release and by decreasing uterine contractions.
Nausea, bloating and breast tenderness, are considered as the early side effects of OCPs and will usually improve with continued use. The most common side effect is breakthrough bleeding which is usually associated with lower estrogen doses and other adverse effects caused by the pills include hypertension, increased risk of cervical cancer and venous thromboembolism. Although common perception considers weight gain as a side effect, several studies have shown that no significant weight gain is associated with OCPs, particularly with low-dose formulations. Considering this, the patient should be reassured that her weight gain is not associated with regular use of OCPs.In patients who are not sexually active, nonsteroidal anti-inflammatory drugs are considered as the first-line treatment for primary dysmenorrhea. As stopping contraception will increase this Patient’s risk of unintended pregnancy this is not advisable to her.
Switching the patient to a copper intrauterine device (IUD) will decrease systemic side effects, but as its inflammatory reaction in the uterus may increase pain symptoms, copper IUD is not recommended for patients with dysmenorrhea.
As Medroxyprogesterone will increase body fat and decrease lean muscle mass resulting in weight gain is not a good option for this patient. Also medroxyprogesterone due to its risk of significant loss of bone mineral density, is not recommended for adolescents or young women. So it can be used in this age group only if other options are unacceptable.
Presence of estrogen component is the main reason behind the side effects of combination OCPs. Progesterone-only pills have relatively fewer side effects but as they do not inhibit ovulation, they are less effective for treating dysmenorrhea and for contraception.
Combination oral contraceptive pills are the first-line therapy for primary dysmenorrhea in sexually active patients. Its side effects include breakthrough bleeding, hypertension, and increased risk of venous thromboembolism. Researches proves that weight gain is usually not an adverse effect of OCPs.

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.

You are attending the labour of a patient who has had a prolonged 1st stage of labour. You note the fetal head start to retract after being tightly applied to the vulva (turtle-neck sign). What is the next most appropriate management step?
Your Answer: C-section
Correct Answer: McRoberts' manoeuvre
Explanation:Signs of shoulder dystocia:
– Difficulty with delivery of the face and chin
– The head remaining tightly applied to the vulva or even retracting (turtle-neck sign)
– Failure of restitution of the fetal head
– Failure of the shoulders to descend
Upon identifying shoulder dystocia additional help should be called and McRoberts manoeuvre (flexion and abduction of the maternal hips, positioning the maternal thighs on her abdomen) should be performed first. Fundal pressure is associated with uterine rupture and should not be used. -

One year ago, Pap smear was done at your clinic for a 53 year old female patient. HPV type 42 was detected and reported as LSIL. A repeat pap smear after 12 months shows no change.
What is the next best step in management?Your Answer:
Correct Answer: Refer for colposcopy
Explanation:The management of low-grade squamous intraepithelial lesions (LSIL) on cervical cytology in women ages 25 years or older depends upon whether the patient underwent high-risk human papillomavirus (HPV) testing.
Women in this age group comprise two different populations in terms of cervical cancer screening strategies. Professional organizations recommend that women ages 25 to 29 years be screened with cytology alone, while women 30 years or older should be screened with cytology and HPV co-testing. Thus, the American Society for Colposcopy and Cervical Pathology (ASCCP) prefers that women ages 25 to 29 years are not managed based upon HPV results, even if an HPV test was performed at the time of screening. For women with ages 30 years or older and HPV positive, colposcopy must be performed.

What is the contraception of choice for epileptics on enzyme inducing antiepileptic drugs?
Your Answer:
Correct Answer: Levonorgestrel-releasing intrauterine contraceptive device
Explanation:Clinical decision making which contraceptive regimen is optimal for an individual woman with epilepsy is one of the most challenging tasks when taking care of women with epilepsy. The bidirectional interactive potential of antiepileptic drugs (AEDs) and hormonal contraceptives needs to be taken into account. Enzyme inducing (EI)-AEDs may reduce the contraceptive efficacy of hormonal contraceptives.
If combined oral contraceptives (COCs) are used in combination with EI-AEDs, it is recommended to choose a COC containing a high progestin dose, well above the dose needed to inhibit ovulation, and to take the COC pill continuously (“long cycle therapy”). But even with the continuous intake of a COC containing a higher progestin dose contraceptive safety cannot be guaranteed, thus additional contraceptive protection may be recommended.
Progestin-only pills (POPs) are likely to be ineffective, if used in combination with EI-AEDs.
Subdermal progestogen implants are not recommended in patients on EI-AEDs, because of published high failure rates.
Depot medroxyprogesterone-acetate (MPA) injections appear to be effective, however they may not be first choice due to serious side effects (delayed return to fertility, impaired bone health).
The use of intrauterine devices is an alternative method of contraception in the majority of women, with the advantage of no relevant drug–drug interactions. The levonorgestrel intrauterine system (IUS) appears to be effective, even in women taking EI-AEDs. Likelihood of serious side effects is low in the IUS users.

A 26-year-old pregnant woman in her third trimester, was admitted with headache, abdominal pain and visual disturbances. Shortly after, she had a fit. What is the most appropriate management?
Your Answer:
Correct Answer: 4g MgSO4 in 100ml 0.9% Normal saline in 5 min.
Explanation:The woman is most probably suffering from eclampsia.
Magnesium sulphate (MgSO4) is the agent most commonly used for treatment of eclampsia and prophylaxis of eclampsia in patients with severe pre-eclampsia. It is usually given by either intramuscular or intravenous routes. The intramuscular regimen is most commonly a 4 g intravenous loading dose, immediately followed by 10 g intramuscularly and then by 5 g intramuscularly every 4 hours. The intravenous regimen is given as a 4 g dose, followed by a maintenance infusion of 1 to 2 g/h by controlled infusion pump. -

Which of the following hormones inhibits lactogenesis during pregnancy?
Your Answer:
Correct Answer: Oestrogen and Progesterone
Explanation:Under the influence of prolactin, oestrogen and progesterone and human placental lactogen (hPL), the mammary epithelium proliferates but remains presecretory during mammogenesis. Lactogenesis is inhibited by high circulating levels of progesterone and oestrogen which block cortisol binding sites. Cortisol would have otherwise have worked synergistically with prolactin in milk production. A sharp decrease in progesterone levels after delivery allows prolactin and oxytocin to stimulate milk production and the milk ejection reflex in response to suckling. Prolactin continues to maintain milk production in galactopoiesis.

Physiological changes in the reproductive system include:
Your Answer:
Correct Answer: The uterus 1st enlarges by hyperplasia then by hypertrophy
Explanation:Although uterine growth during the first few weeks of pregnancy is accomplished by increased numbers of smooth muscle cells (i.e. hyperplasia) and a smaller contribution from increased cell size (i.e. hypertrophy), the predominant growth of the uterus during pregnancy is by way of stretch‐induced myometrial hypertrophy. This ongoing process of stretch‐induced tissue remodelling and smooth muscle hypertrophy is accompanied by the lack of uterine contractions during most of gestation to accommodate the developing foetus (phase 0 of parturition). Phase 1 of parturition represents myometrial activation. The final stages of pregnancy are characterized by increases in spontaneous low‐amplitude contractions that gradually increase in frequency, rhythmicity and strength, normally culminating in labour and delivery of the foetus at term (phase 2 of parturition).

What percentage of pregnancies will be uncomplicated following a single episode of reduced fetal movements?
Your Answer:
Correct Answer: 70%
Explanation:Reduced fetal movements can be the first indication of possible fetal abnormalities. Movements are first perceived by the mother from about 18-20 weeks gestation, increase in size and frequency until 32 weeks gestation when they plateau at about 31 movements per hour. Investigations for reduced fetal heart rate include auscultation of the fetal heart rate using a handheld doppler device, and a cardiotocograph or ultrasound if the foetus is above 28 weeks gestation. About 70% of women who experience one episode of reduced fetal movement have uncomplicated pregnancies. They are advised to report to a maternal unit if another episode occurs.

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:
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. -

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

A 30 year old patient is due for delivery in about two weeks. She has some concerns after a family member recently gave birth to a baby with profound hearing loss due to an infection. Which of the following would you describe to her as the most common infective cause of congenital hearing loss?
Your Answer:
Correct Answer: Cytomegalovirus
Explanation:Congenital cytomegalovirus infections are the most common cause of sensorineural hearing loss in babies. Cytomegalovirus infection during the perinatal period can be transferred to the foetus especially if the primary infection is during pregnancy. Babies born with congenital CMV are either symptomatic or develop symptoms later in life. Some of the features of CMV infection include sensorineural hearing loss, visual impairment, cerebral palsy, microcephaly and seizures. Other causes of infective congenital sensorineural hearing loss include: Rubella, HIV, Herpes Simplex Virus, Measles, Varicella Zoster virus, Mumps and West Nile Virus.

A 20-year-old female patient who is experiencing pelvic pain is being cared for at your clinic. She describes bilateral pain that began gradually and was accompanied by fever, vaginal discharge, and mild dysuria.
Her pelvic examination demonstrates uterine, adnexal, and cervical motion tenderness.
Which of the following is the most likely cause of the pain?Your Answer:
Correct Answer: PID
Explanation:Pelvic inflammatory disease (PID) refers to acute and subclinical infection of the upper genital tract in women, involving any or all of the uterus, fallopian tubes, and ovaries; this is often accompanied by involvement of the neighbouring pelvic organs. It results in endometritis, salpingitis, oophoritis, peritonitis, perihepatitis, and/or tubo-ovarian abscess.
Lower abdominal pain is the cardinal presenting symptom in women with PID. The abdominal pain is usually bilateral and rarely of more than two weeks’ duration. The character of the pain is variable, and in some cases, may be quite subtle. The recent onset of pain that worsens during coitus or with jarring movement may be the only presenting symptom of PID. The onset of pain during or shortly after menses is particularly suggestive.
Other non-specific complaints include urinary frequency and abnormal vaginal discharge.
Ovarian cyst, uterine leiomyoma, appendicitis or ectopic pregnancy do not present with fever and vaginal discharge although tenderness is noted in appendicitis and ectopic pregnancy. Therefore, these options do not explain the patient’s symptoms.

A sexually active young woman comes in with frothy, foul-smelling vaginal discharge. Dysuria and dyspareunia are also present. The genital region seems to be quite reddish.
What is the potential danger associated with this presentation?Your Answer:
Correct Answer: Increased risk of cervical cancer
Explanation:TV infection is associated with both LR and HR-HPV infection of the cervix, as well as with ASC-US and HSIL. The signs and symptoms of trichomoniasis are present in this patient. Trichomonas vaginalis is the reason.
Increased vaginal discharge that is frothy, yellowish, and has an unpleasant odour are among the symptoms. It’s frequently linked to dyspareunia and dysuria. Normally, the genital area is red and painful.In both men and women, trichomoniasis can cause preterm labour and raise the risk of infertility. Both the patient and the partner must be treated at the same time.
The active infection can be treated with a single oral dose of metronidazole 2 g taken with food.
To avoid disulfiram-like symptoms, alcohol should be avoided during the first 24-48 hours after treatment. -

A 30-year-old woman living in England had a cervical smear test one month ago. There were no cervical abnormalities visualised at the time of the smear. She has no symptoms of unusual vaginal bleeding and her previous smear results have always been negative. She received the following report: 'Your recent smear was negative with no evidence of nuclear abnormalities.' When will she be routinely recalled for her next smear?
Your Answer:
Correct Answer:
Explanation:Women aged 25-49 years living in England are routinely recalled for screening every three years. Women receive their first invitation for cervical screening at 25 years of age. They are not invited earlier as changes in the young cervix can be normal and result in unnecessary treatment. Provided the smears remain negative and there are no symptoms to suggest cervical cancer, the routine recall is three years for women aged 25-49 years. Women aged 50-64 years old are routinely recalled for a smear every five years. After the age of 65 years, women are only screened if they have not had a smear since the age of 50 years (including those who have never had a smear) or those who have had recent abnormal smears. This is because due to the natural history and progression of cervical cancer, it is highly unlikely that women over 65 years old will go on to develop the disease.

On examination, patient is conscious and pale, with a blood pressure of 70/45 mm of Hg and pulse rate of 115 bpm. Abdomen is found to be irregularly distended with shifting dullness and fluid thrill. Fetal heart sounds are not audible.
Which among of the following will most likely be her diagnosis?Your Answer:
Correct Answer: Uterine rupture
Explanation:The given case where the patient presents with sudden abdominal pain, cessation of uterine contraction and the urge to push along with vaginal bleeding is typical for uterine rupture. Examination shows a decreased or lost fetal heart rate, along with signs of fluid collection including fluid thrill and shifting dullness due to the entry of blood into the peritoneal cavity.
Other common manifestations of uterine rupture include:
– Loss of the station of the fetal presenting part
– Vaginal bleeding which is not be proportionate to the hemodynamic status
-Maternal tachycardia and hypotension ranging from subtle to severer shock
– Uterine tenderness
– Change in uterine shape and contour
– Easily palpable fetal parts
– No fetal presentation on vaginal examination
– Hematuria if the rupture extends to the bladder
Anterior lower transverse segment is the most common site of spontaneous uterine rupture.Placenta previa usually presents as painless vaginal bleeding, which rules it out as the diagnosis in given case.
Vaginal bleeding with a tender and tense uterus is the presentation in placental abruption, also contrary to uterine rupture, uterine contractions will continue in case of placental abruption.
Cervical laceration can be a possibility, but in such cases more amount of vaginal blood loss was expected in this patient with hemodynamic instability. Also symptoms like deformed uterus, abdominal distention and cessation of contractions are inconsistent with cervical laceration.
Excessive generation of thrombin and fibrin in the circulating blood results in Disseminated intravascular coagulation (DIC) which leads to increased platelets aggregation and consumption of coagulation factors resulting in consequent bleeding at one site and thromboembolism at another. Placental abruption and retained products of conception in the uterine cavity are the most common obstetric causes of DIC. The condition will not fit as diagnosis in this clinical scenario.

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

How many days after fertilisation does the blastocyst hatch from the zone pellucida?
Your Answer:
Correct Answer: 5-Jul
Explanation:Shortly after the morula enters the uterus, around the 4th day after fertilization, a clear cystic cavity starts forming inside the morula. The fluid passes through the zona pellucida from the uterine cavity and hence forms the blastocyst.

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

A 29-year-old lady comes to your clinic for a refill on her oral contraceptive tablets (Microgynon 30®). You discover she has a blood pressure of 160/100mmHg during your examination, which is confirmed by a second reading 20 minutes later. Her husband and she are expecting a child in six months.
Which of the following recommendations is the best for her?Your Answer:
Correct Answer: She should stop OCP, use condoms for contraception and reassess her blood pressure in 3 months
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.
All other options are incorrect.

Regarding placental anatomy:
Your Answer:
Correct Answer: Fetal blood vessels develop in the mesenchymal core of the chorionic villi
Explanation:The chorionic plate represents the fetal surface of the placenta, which in turn is covered by the amnion. The amnion is composed of a single layered epithelium and the amnionic mesenchyme, an avascular connective tissue. The amnionic mesenchyme is only weakly attached to the chorionic mesenchyme and can easily be removed from the delivered placenta. The chorionic mesenchyme contains the chorionic vessels that are continuous with the vessels of the umbilical cord. Within the mesoderm of secondary villi, haematopoietic progenitor cells develop and start to differentiate. At about day 20 post-conception, first placental blood cells and endothelial cells develop independent of the vascular system of the embryo proper.13 14 The development of first placental vessels transforms the respective villi into tertiary villi.

A 61-year-old woman presents to OBGYN clinic with a complaint of irregular bleeding per vagina for the last 3 months. Her past medical history is not significant and she went through menopause around a decade ago.
A cervical screening test is performed and comes back normal. PCR for chlamydia is also negative. Endometrial thickness of around 8mm is seen on transvaginal ultrasound.
What would be the next step of management?Your Answer:
Correct Answer: Referral to the gynaecologist for endometrial biopsy
Explanation:This patient had postmenopausal vaginal haemorrhage and an 8mm endometrial thickness. Endometrial thickness of 4mm or more in a postmenopausal woman with vaginal bleeding necessitates an endometrial biopsy to rule out endometrial cancer, and this patient should be referred to a gynaecologist for this procedure.
All of the other choices are incorrect. -

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

Which of the following studies would you do next to forecast ovulation?Your Answer:
Correct Answer: Serum progesterone
Explanation:This patient has a regular and long menstrual period. The most crucial thing in this case is to rule out anovulation.
Serum progesterone concentration is the best test for detecting ovulation.
Ovulation has occurred if the level is greater than 20nmol/L.
This test should be performed 3 to 10 days prior to the start of the next anticipated period. -

Which of the following is the most appropriate for diagnosis of Bacterial Vaginosis (BV)?
Your Answer:
Correct Answer: Amsel's criteria
Explanation:Diagnosis can be made using the Amsel’s criteria:
1. Presence of clue cells on microscopic examination (these cells are epithelial cells covered with the bacteria).
2. Creamy greyish discharge.
3. Vaginal pH of more than 4.5.
5. Positive whiff test – release of fishy odour on addition of alkali solution. Other criteria include the nugent score and the Hay/Ison criteria. The Nugent score estimates the relative proportions of bacterial morphotypes to give a score between 0 and 10 (<4 = normal, 4-6 = intermediate, >6 = BV)
The Hay/Ison criteria
Grade 1 (Normal): Lactobacillus morphotypes predominate
Grade 2 (Intermediate): Mixed flora with some Lactobacilli present, but Gardnerella or Mobiluncus morphotypes also present
Grade 3 (BV): Predominantly Gardnerella and/or Mobiluncus morphotypes. Few or absent Lactobacilli. -
