At ovulation the surge in LH causes rupture of the mature oocyte via action on what?
Your Answer: Granulosa interna
Correct Answer: Theca externa
Explanation:The luteinizing hormone (LH) surge during ovulation causes: Increases cAMP resulting in increased progesterone and PGF2 production PGF2 causes contraction of theca externa smooth muscle cells resulting in rupture of the mature oocyte

In which part of the body does clomiphene trigger ovulation by antagonising oestrogen receptors?
Your Answer:
Correct Answer: Hypothalamus
Explanation:Clomiphene citrate is widely used in the induction of ovulation, especially in the treatment of anovulatory infertility and in conditions such as PCOS. The drug functions as a selective oestrogen receptor modulator, which acts in the hypothalamus to indicate low serum oestrogen levels. Reduced levels of negative feedback stimulate the secretion of GnRH from the hypothalamus, which in turn stimulate the production of gonadotropins (FSH and LH) from the anterior pituitary. These work to increase ovarian follicular activity.

Changes in the urinary tract system in pregnancy include:
Your Answer:
Correct Answer: Increase in the glomerular filtration rate (GFR)
Explanation:Pregnancy involves remarkable orchestration of physiologic changes. The kidneys are central players in the evolving hormonal milieu of pregnancy, responding and contributing to the changes in the environment for the pregnant woman and foetus. The functional impact of pregnancy on kidney physiology is widespread, involving practically all aspects of kidney function. The glomerular filtration rate increases 50% with subsequent decrease in serum creatinine, urea, and uric acid values.Â

According to the NICE guidelines on intrapartum care a multiparous women with intact membranes should be offered amniotomy if there is inadequate progress of the active second stage of labour (in terms of rotation and/or descent of the presenting part) after how long?
Your Answer:
Correct Answer: 30 minutes
Explanation:Multiparous women active 2nd stage labour: Suspect delay if progress inadequate after 30 minutes Diagnose delay if progress inadequate after 1 hour If delay is suspected amniotomy should be offered if membranes are intact If delay diagnosed then preparations should be made for C-section Nulliparous women active 2nd stage labour: Suspect delay if progress inadequate after 1 hour Diagnose delay if progress inadequate after 2 hours If delay is suspected amniotomy should be offered if membranes are intact If delay diagnosed then preparations should be made for C-section

A 30 year old women comes to see you and advises she has felt a little unwell with diarrhoea and flu like symptoms. She is 28 weeks pregnant. Upon questioning she discloses she ate a soft cheese and deli meats platter 5 days earlier. A blood culture confirms listeria infection. What is the appropriate treatment (she has no known drug allergies)?
Your Answer:
Correct Answer: Amoxicillin
Explanation:The diagnosis of listeria depends on clinical suspicion and isolation of the organism from blood, vaginal swabs or the placenta. Meconium staining of the amniotic fluid in a preterm foetus may increase clinical suspicion for listeriosis. For women with listeriosis during pregnancy, intravenous antibiotic treatment (ampicillin 2 g given every 6 hours) is indicated.

A 22 year old woman is being followed up 6 weeks after a surgical procedure to evacuate the uterus following a miscarriage. The histology has shown changes consistent with a hydatidiform mole. What is the single most appropriate investigation in this case?
Your Answer:
Correct Answer: Serum B-HCG
Explanation:The most appropriate test for a hydatiform mole is serum beta hCG levels, which are consistently raised in these patients. The levels return to normal when the pregnancy is terminated.

Question 9

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

Question 10

A 25-year-old female presents to a gynaecologist with a complaint of abnormal vaginal bleeding, usually postcoital. On pelvic examination, the cervix of was found to be of an unusually bright red colour and its texture was rougher than normal. Which of the following will you choose as the next step in the management of this condition?
Your Answer:
Correct Answer: Cervical smear (2nd line)
Explanation:Before considering invasive procedures, a cervical smear must first be performed. Antibiotics can only be given when inflammation has been confirmed and culture results have identified the organism causing the inflammation. Endometrial ablation, colposcopy and vaginal US are all invasive procedures that are not relevant in the immediate management of this patient.
