You diagnose Erb-Duchenne palsy in a baby born with shoulder dystocia who suffered a brachial plexus injury. Which of the following nerve roots are likely to be affected?
Your Answer: C5 and C6
Explanation:Shoulder dystocia occurs when the fetal shoulder impacts on the maternal symphysis or sacrum during vaginal delivery. About 10% of babies with shoulder dystocia will suffer a brachial plexus injury, the most common one being Erb-Duchenne palsy. In Erb’s palsy, the upper nerve roots C5 and C6 are damaged due to excessive widening of the angle between the head and the shoulder. This causing temporary paralysis in the affected arm whereby the infant will present with its hand hanging limp by his side, internal rotation of the forearm, plus wrist and finger flexion. This sign is called the ‘waiter’s tip hand’. The palsy usually resolves spontaneously in a large proportion of cases.

A 34 year old patient who has just undergone a C-section delivery has lost almost 1 litre of blood. You suspect uterine atony as the likely cause, and have bimanually compressed the uterus. Which of the following pharmacological interventions should follow?
Your Answer: Syntocin 5u by slow intravenous injection
Explanation:In the management of postpartum haemorrhage, it is essential that the bleeding is first mechanically prevented, followed by the administration of oxytocic drugs, which cause the uterine smooth muscle to contract and clamping off bleeding sites in the endometrium. The drug of choice in the treatment protocol of PPH is 5 units of syntocin, a synthetic oxytocin uterotonic, by slow intravenous infusion. This is particularly suitable in the case of uterine atony. Other uterotonics, misoprostol, carboprost, ergometrine, can be used, but are not as effective in an emergency setting.

At what week in pregnancy is testing for gestational diabetes (GD) advised
Your Answer: 24-28 weeks of pregnancy if past history of GD
Correct Answer: As soon as possible after booking if past history of GD
Explanation:Gestational diabetes (GDM) occurs in 2–9 per cent of all pregnancies. Screening for diabetes in pregnancy can be justified to diagnose previously unrecognized cases of pre-existing diabetes and to identify a group of women who are at risk of developing NIDDM later in life. No single screening test has been shown to be perfect in terms of high sensitivity and specificity for gestational diabetes. Urinary glucose is unreliable, and most screening tests now rely on blood glucose estimation, with an oral glucose tolerance test commonly used. The aim of glucose control is to keep fasting levels between 3.5 and 5.5 mmol/L and postprandial levels 7.1 mmol/L, with insulin treatment usually indicated outside these ranges. The women should be tested as soon as possible after booking if there is a history of GD.

A 24 year old lady is rushed to the emergency department complaining of vaginal spotting and abdominal cramping. Her 6 week pregnancy was confirmed by ultrasound scan last week. On speculum examination, the cervical os is open with blood noted around it.
Which of the following is the most likely diagnosis?Your Answer: Complete Miscarriage
Correct Answer: Inevitable Miscarriage
Explanation:A miscarriage is defined as the spontaneous loss of a pregnancy before the age of viability at 24 weeks in the UK. An inevitable miscarriage occurs with the usual symptoms of a miscarriage such as menstrual-like cramping, vaginal bleeding and a dilated cervix. The gestational sac has ruptured but products of conception have not been passed. The products of conception will eventually pass.
A missed miscarriage is described as a loss of pregnancy without vaginal bleeding, loss of tissue, cervical changes or abdominal pain. During a scan, a fetal heartbeat is not observed, and the gestational sac may be small.
A threatened miscarriage is when the cervix dilates and uterine bleeding is seen; the pregnancy could still be viable.
A complete miscarriage occurs when all the products of conception are expelled from the uterus, bleeding has stopped, and the cervix has closed up after dilation. Recurrent miscarriages are described as spontaneous pregnancy loss of more than 2 to 3 consecutive times.

Per the guidelines from the International Federation of Gynaecologists and Obstetricians (FIGO), the active management of the third stage is summarised as follows:
1. The administration of a uterotonic (oxytocin, ergometrine or misoprostol), within one minute of fetal delivery,
2.Controlled cord traction with manual support to the uterus until placental delivery
3. Fundal massage immediately after placental delivery. -

Which of the following statements is true regarding management of caesarean section?
Your Answer: Peritoneum should be closed using monofilament sure e.g. 3-0 PDS
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. -

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

An HIV positive woman who is 18 weeks pregnant complains of frothy yellow vaginal discharge and vaginal soreness. A wet mount and microscopy confirms a Trichomonas vaginalis infection. Which of the following is the most appropriate treatment regime?
Your Answer: Metronidazole 500mg BD 7 days
Explanation:Trichomoniasis is considered a sexually transmitted infection found both in men and women caused by the flagellate protozoan Trichomonas vaginalis. The organism is mainly found in the vagina and the urethra. Though many infected women can be asymptomatic, they can also present with yellow frothy vaginal discharge, itching and vaginitis, dysuria or an offensive odour. For the diagnosis of t. vaginalis in women, a swab is taken from the posterior fornix during speculum examination and the flagellates are detected under light-field microscopy. The recommended treatment for t. vaginalis for a HIV positive woman who is pregnant is 500mg of metronidazole twice daily for 7 days. High dose metronidazole as a 2g single dose tablet is not advised during pregnancy. All sexual partners should also be treated, and screening for other STIs should be carried out.

A 67 year old patient with endometrial carcinoma is to undergo staging investigations. There is evidence of invasion into the vaginal wall, but the lymph nodes are spared, and there is no distant metastasis. According to FIGO, what stage is this?
Your Answer: 2
Correct Answer: 3B
Explanation:Endometrial cancer is one of the most common gynaecological malignancies present in postmenopausal women, with a peak incidence between the ages of 60-89. Factors associated with endometrial cancer include obesity, hypertension and diabetes. Full staging for endometrial cancer is surgical, including several other radiologic investigations. According to FIGO staging classifications:
Stage 1 indicates a tumour confined to the uterine body
Stage 2 indicates the invasion of the cervical stroma
Stage 3 indicates local and regional spread, where the tumour invades the serosa in stage 3A, spreads to the vagina and parametrium in stage 3B, and metastasizes to the pelvic or para-aortic lymph nodes in stage 3C.
Stage 4 indicates tumour invasion on the bladder or bowel mucosa, or distant metastasis. -

A 30 year old woman with a history of two previous C section deliveries, is rushed to the hospital for an emergency c-section at 36 weeks gestation due to antenatal haemorrhage. Upon examination of the uterus, the placenta has invaded the myometrium but the serosa is spared. Which of the following identifies this condition?
Your Answer: Placenta Increta
Explanation:Abnormal placental adherence to the uterus, generally termed Placenta Accreta, is divided into 3 conditions.
– Placenta accreta: refers to the invasion of the chorionic villi beyond the decidual surface of the myometrium.
– Placenta increta: the villi invade deep into the myometrium but spare the serosa;
– Placenta percreta: the chorionic villi invade through the myometrium, penetrate the uterine serosa, and may invade surrounding pelvic structures.These conditions can predispose patients to obstetric bleeding in the third trimester, often requiring emergency intervention.
Risk factors in the development of an abnormal placental adherence include previous c-sections. Placenta Previa, is also a cause of antepartum haemorrhage and serves as a risk factor in the development of abnormal placental adherence.

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: Increased sensitivity of the area postrema
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 organism is the most common cause of puerperal sepsis?
Your Answer: Gardnerella vaginalis
Correct Answer: Group A Streptococcus
Explanation:Puerperal sepsis is defined as sepsis occurring after birth until 6 weeks postnatal. The most common cause of puerperal sepsis is Group A streptococcus. Until 1937, puerperal sepsis was the major cause of maternal mortality. The discovery of sulphonamides in 1935 and the simultaneous reduction in the virulence of the haemolytic streptococcus resulted in a dramatic fall in maternal mortality.

The COCP (Combined Oral Contraceptive Pill) causes all of the following biochemical effects EXCEPT which one?
Your Answer: Reduction in adrenal androgen secretion
Correct Answer: Elevate FSH
Explanation:Remember patients with PCOS have elevated LH. COCPs suppress synthesis and secretion of FSH and the mid-cycle surge of LH, thus inhibiting the development of ovarian follicles and ovulation COCPs reduce hyperandrogenism as reduced LH secretion results in decreased ovarian synthesis of androgens. Furthermore they stimulate the liver to produce Sex Hormone Binding Globulin which leads to decreased circulating free androgens. Other mechanisms include reduction in adrenal androgen secretion and inhibition of peripheral conversion of testosterone to dihydrotestosterone and binding of dihydrotestosterone to androgen receptors

A 28 year old primigravida carrying a twin pregnancy presents at 32 weeks gestation. She is lethargic, clinically jaundiced and complains of abdominal pain with frequent vomiting. A summary of her blood results are as follows: Elevated aspartate transaminase (AST) and alanine transaminase (ALT) levels · Decreased blood glucose levels · Elevated levels of blood ammonia. What is the likely diagnosis?
Your Answer: Hepatitis A
Correct Answer: Acute fatty liver of pregnancy
Explanation:This patients bloods and symptoms suggest she has hepatic impairment. Acute fatty liver of pregnancy typically presents after the 30th week. The usual symptoms in the mother are non-specific including nausea, vomiting, anorexia (or lack of desire to eat) and abdominal pain; excessive thirst may be the earliest symptom without overlap with otherwise considered normal pregnancy symptoms; however, jaundice and fever may occur in as many as 70% of patients.
Many laboratory abnormalities are seen in acute fatty liver of pregnancy. Liver enzymes are elevated, with the AST and ALT enzymes ranging from minimal elevation to 1000 IU/L, but usually staying in the 300-500 range. Bilirubin is almost universally elevated. Alkaline phosphatase is often elevated in pregnancy due to production from the placenta, but may be additionally elevated. Other abnormalities may include an elevated white blood cell count, hypoglycemia, elevated coagulation parameters, including the international normalized ratio, and decreased fibrinogen. There may be increases of ammonia, uric acid aswell.
Recent studies have shown that being a primigravida, multiple pregnancies, carrying a male fetus, other liver diseases during pregnancy, previous history of AFLP, and pre-eclampsia are the potential risk factors for AFLP

Your Answer: <0.5%
Correct Answer: 15%
Explanation:Vulvar Intraepithelial Neoplasia (VIN) is a non-invasive squamous type lesion that carries a 15% chance of developing into squamous cell carcinoma of the vulva. Human Papillomavirus (HPV) infection, or chronic inflammatory conditions such as lichen sclerosis and lichen planus, can cause changes in the basal cells of the vulvar epithelium. Other risk factors of VIN include multiple sexual partners, cigarette smoking, and immunocompromised states. Diagnosis is by clinical examination and a biopsy confirms neoplasia.

A 36 year old patient is diagnosed with cervical cancer and staging investigations show there is parametrial involvement but it is confined within the pelvic wall and does not involve the lower 1/3 vagina. There is no evidence of hydronephrosis. What FIGO stage is this?
Your Answer: 2B
Explanation:It is stage 2B. Stage I: is strictly confined to the cervix; extension to the uterine corpus should be disregarded. The diagnosis of both Stages IA1 and IA2 should be based on microscopic examination of removed tissue, preferably a cone, which must include the entire lesion.
2010 FIGO classification of cervical carcinoma:
Stage IA: Invasive cancer identified only microscopically. Invasion is limited to measured stromal invasion with a maximum depth of 5 mm and no wider than 7 mm.
Stage IA1: Measured invasion of the stroma no greater than 3 mm in depth and no wider than 7 mm diameter.
Stage IA2: Measured invasion of stroma greater than 3 mm but no greater than 5 mm in depth and no wider than 7 mm in diameter.Stage IB: Clinical lesions confined to the cervix or preclinical lesions greater than Stage IA. All gross lesions even with superficial invasion are Stage IB cancers.
Stage IB1: Clinical lesions no greater than 4 cm in size.
Stage IB2: Clinical lesions greater than 4 cm in size.Stage II: carcinoma that extends beyond the cervix, but does not extend into the pelvic wall. The carcinoma involves the vagina, but not as far as the lower third.
Stage IIA: No obvious parametrial involvement. Involvement of up to the upper two-thirds of the vagina.
Stage IIB: Obvious parametrial involvement, but not into the pelvic sidewall.Stage III: carcinoma that has extended into the pelvic sidewall. On rectal examination, there is no cancer-free space between the tumour and the pelvic sidewall. The tumour involves the lower third of the vagina. All cases with hydronephrosis or a non-functioning kidney are Stage III cancers.
Stage IIIA: No extension into the pelvic sidewall but involvement of the lower third of the vagina.
Stage IIIB: Extension into the pelvic sidewall or hydronephrosis or non-functioning kidney.Stage IV: carcinoma that has extended beyond the true pelvis or has clinically involved the mucosa of the bladder and/or rectum.
Stage IVA: Spread of the tumour into adjacent pelvic organs.
Stage IVB: Spread to distant organs. -

A 26 year old patient attends the maternity unit as her waters have broken but she hasn't had contractions. She is at 39+5 weeks gestation. Speculum examination confirms prelabour rupture of membranes (PROM). What is the risk of serious neonatal infection with PROM?
Your Answer: 1 in 1000
Correct Answer: 1 in 100
Explanation:In pregnancy, term refers to the gestational period from 37 to 41+6 weeks. Preterm births occur between 24 and 36+6 weeks. Only 1% of women who go into PROM have risk of having serious neonatal infections.
Management of PROM:
60% of patients with PROM will go into labour within 24 hrs
Induction is appropriate if >34 weeks gestation and more than 24 hours post rupture when labour hasn’t started.
If < 34 weeks, induction of labour should not be carried out unless there are additional obstetric indications e.g. infection -

How long does involution of the uterus take after parturition?
Your Answer: 4-6 weeks
Explanation:In the period immediately after the delivery of the placenta, known as the puerperium, the female reproductive system begins to undergo some physiological changes to return to a non-pregnant state. One of these changes is uterine involution. The myometrium contracts, constricting blood vessels which impedes blood flow. It is thought that the uterine tissues then undergo apoptosis and autophagy. It takes about 4-6 weeks for the uterus to decrease is size from about 1 kg to 60 grams.

Which one of the following has the most significant effect on slowing drug metabolism in pregnancy?
Your Answer: Increased hepatic blood flow
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. -

What percentage of pregnancies will be uncomplicated following a single episode of reduced fetal movements?
Your Answer: 98%
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.

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: McRoberts' manoeuvre
Explanation:Call for help.
• Ensure personnel are available to ‘scribe’.
Document the time the head delivered, which shoulder is anterior (this is the arm most vulnerable to injury) and the times at which each manoeuvre is employed.
• Drop the level of the delivery bed as low as it will go, and flatten the back of the bed so the woman is completely flat. Remove the foot of the bed to allow access.
• Assess for and perform an episiotomy, if needed.
• Using one assistant on each of the mother’s legs, flex and abduct the legs at the hip (thighs to abdomen, known as McRoberts manoeuvre). This flattens the lumbosacral spine and will facilitate delivery is around 90 per cent of cases.
• If this fails, suprapubic pressure should be
applied by another assistant. This should be
applied over the posterior aspect of the anterior fetal shoulder and will act to push the shoulders together. It can be used in a constant and then rocking motion.
• If both these fail, then internal manoeuvres are necessary. The order of these will depend on the skill and experience of the person conducting the delivery and the individual case. These manoeuvres have been named after famous obstetricians, but it is the process rather than the name that is important:
• An attempt can be made to rotate the baby, so that the shoulders enter the diagonal to allow delivery. The first procedure is usually to insert a hand behind the anterior shoulder, and push it towards the chest (Rubin II). This will adduct the shoulders then push them into the diagonal. This can be combined with pressure on the
anterior aspect of the posterior shoulder
to aid rotation (Woods’ screw). If this fails,
an attempt can be made to rotate the baby
in the opposite direction (reverse Woods’
screw). Delivery of the posterior arm can be
attempted passing a hand into the vagina, in
front of the posterior shoulder and deliver
the posterior arm by swinging it in front of
the fetal chest.
If these all fail, the patient can be moved on to all fours as this increases the anterior–posterior diameter of the inlet. In this position, the posterior arm can be delivered.
After this, manoeuvres of last resort include a symphysiotomy, in which the maternal symphysis is divided, Zavanelli’s, in which the head is reduced back into the vagina and a Caesarean section performed and intentional fracture of the fetal
clavicle. -

In a patient who undergoes a medical abortion at 10 weeks gestation, what advice would you give regarding Rhesus Anti-D Immunoglobulin?
Your Answer: All RhD Positive women should receive Anti-D IgG
Correct Answer: All RhD-negative women who are not alloimmunized should receive Anti-D IgG
Explanation:The Rhesus status of a mother is important in pregnancy and abortion. The exposure of an Rh-negative mother to Rh antigens from a positive foetus, will influence the development of anti-Rh antibodies. This may cause problems in subsequent pregnancies leading to haemolysis in the newborn. Rh Anti RhD- globulin is therefore given to non-sensitised Rh-negative mothers to prevent the formation of anti-Rh antibodies within 72 hours following abortion. Anti RhD globulin is not useful for already sensitized, or RhD positive mothers.

What percentage of infants will have permanent neurological dysfunction as a result of brachial plexus injury secondary to shoulder dystocia?
Your Answer: 50%
Correct Answer:
Explanation:Shoulder dystocia occurs when the anterior or posterior fetal shoulder impacts on the maternal symphysis or sacrum and may require additional manevours to release the shoulders after gentle downward traction has failed. The most common injury that can occur, is to the brachial plexus due to lateral flexion of the head during traction. This may cause a neurological disability, Erb’s Palsy ( injury to C5 and C6 of the brachial plexus) in which there is a less than 10% chance that this injury would be permanent.

Regarding gestational diabetes which of the following is NOT a recognised risk factor
Your Answer: Previous unexplained stillbirth
Correct Answer: High polyunsaturated fat intake
Explanation:Gestational diabetes (GDM) occurs in 2–9 per cent of all pregnancies. Screening for diabetes in pregnancy can be justify ed to diagnose previously unrecognized cases of pre-existing diabetes and to identify a group of women who are at risk of developing NIDDM later in life. No single screening test has been shown to be perfect in terms of high sensitivity and specific city for gestational diabetes. Urinary glucose is unreliable, and most screening tests now rely on blood glucose estimation, with an oral glucose tolerance test commonly used. The aim of glucose control is to keep fasting levels between 3.5 and 5.5 mmol/L and postprandial levels 7.1 mmol/L, with insulin treatment usually indicated outside these ranges. There are various risk factors for gestational diabetes including increasing age, ethnicity, previous still births etc.

Explanation:The Rotterdam criteria was developed and expanded by the European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine Rotterdam consensus (ESHRE/ASRM) in 2003 and is now the Gold standard in the diagnosis of PCOS. The criteria requires two of three features: anovulation, hyperandrogenism, and polycystic ovaries seen on ultrasound.
The National Institute of Child Health and Human Development (NICHD) attempted to define PCOS in 1990 but omitted ultrasonographic evidence of polycystic ovaries which is considered to be diagnostic of PCOS.
The Androgen Excess Society (AES) served to confirm hyperandrogenism as the central event in the development of PCOS.
The ROME III criteria is used for Irritable Bowel Disease and is therefore not applicable to PCOS.

You see a 28 year old woman who is 22 weeks pregnant. She complains of vaginal soreness and yellow frothy discharge. Microscopy confirms Trichomoniasis. What percentage of infected pregnant women present with yellow frothy discharge?
Your Answer: 2%
Correct Answer: 20%
Explanation:Trichomoniasis is considered a sexually transmitted infection found both in men and women, and is caused by the flagellate protozoan Trichomonas vaginalis. The organism is mainly found in the vagina and the urethra. Though many infected women can be asymptomatic, they can also present with yellow frothy vaginal discharge, itching and vaginitis, dysuria or an offensive odour. About 20-30% of women with the infection however are asymptomatic. For the diagnosis of t. vaginalis in women, a swab is taken from the posterior fornix during speculum examination and the flagellates are detected under light-field microscopy. The recommended treatment for t. vaginalis during pregnancy and breastfeeding is 400-500mg of metronidazole twice daily for 5 -7 days. High dose metronidazole as a 2g single dose tablet is not advised during pregnancy. All sexual partners should also be treated and screened for other STIs.

A patient admitted to the medical ward complains of a mild fever and vaginal discharge. Clue cells are seen on microscopy from a vaginal swab. Which of the following infections feature clue cells?
Your Answer: Actinomycosis
Correct Answer: Bacterial Vaginosis
Explanation:Bacterial vaginosis (BV) is a common infection of the vagina caused by the overgrowth of atypical bacteria, most commonly Gardnerella vaginalis, a gram-negative rod. In diagnosing BV, a swab is taken for microscopy, often revealing clue cells. Clue cells are cells of the vaginal epithelium which are covered by adherent Gardnerella, giving them a distinctive look under the microscope. Though many are asymptomatic, some infected women complain of a greyish, foul-smelling vaginal discharge. Their vaginal fluid pH may also become more alkaline. BV does not however present with pyrexia, so the lady’s fever could be attributed to another cause as she is still a patient on the medical ward.

Your Answer: Psoas muscle
Correct Answer: Uterosacral ligament
Explanation:Lower abdominal pain during menstrual periods and lower back or leg pain are associated with endometriosis in the uterosacral ligaments. Endometriosis can cause diarrhoea and IBS type symptoms. Note Endometriosis on the uterosacral ligament can cause tender nodules to form. These can be palpated during pelvic exam. Tender nodules are specific to endometriosis of the uterosacral ligament so if the question mentions feeling a tender nodule during PV exam think endometriosis of the Uterosacral ligaments!

What is the mode of action of Tranexamic acid?
Your Answer: Inhibits Prostaglandin Synthesis
Correct Answer: Inhibits Plasminogen Activation
Explanation:Tranexamic acid is an antifibrinolytic drug which is one of the treatment options in menorrhagia i.e. heavy menstrual bleeding. It acts by binding to the receptor sites on plasminogen thus preventing plasmin from attaching to those receptors thus inhibiting plasminogen activation.
If pharmaceutical treatment is appropriate NICE advise treatments should be considered in the following order:
1. levonorgestrel-releasing intrauterine system (LNG-IUS) provided at least 12 months use is anticipated
2. tranexamic acid or NSAIDs* or combined oral contraceptives (COCs) or cyclical oral progestogens
3. Consider progesterone only contraception e.g. injected long-acting progestogens*When heavy menstrual bleeding (HMB) coexists with dysmenorrhoea NSAIDs should be preferred to tranexamic acid. Also note NSAIDs and tranexamic are appropriate to use if treatment needed pending investigations.

In reducing the risk of blood transfusion in pregnancy and labour which of the following strategies is recommended?
Your Answer: Pre-autologous blood deposit taken and stored for later use
Correct Answer: A Hb of less than 10.5g/l should prompt haematinics and exclusion of haemoglobinopathies
Explanation:Anaemia in pregnancy is most frequently caused by iron or folate deficiency, however, a wide variety of other causes may be considered, especially if the haemoglobin value is below 9.0 g/dL. A haemoglobin level of 11 g/dL or more is considered normal early in pregnancy, with the upper limit of the ‘normal range’ dropping to 10.5 g/dL by 28 weeks gestation. Haemoglobin < 10.5 g/dl in the antenatal period, one should exclude haemoglobinopathies and consider haematinic deficiency. Oral iron is 1st line treatment for iron deficiency. Anaemia not due to haematinic deficiency will not respond to any form of iron. This should be managed with transfusion

What is the most common cause of sepsis in the puerperium?
Your 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.

The Canadian preterm labour trial which remains a very influential tocolytic trial to date concluded that tocolytics such as a beta agonist have no significant benefit on perinatal mortality or morbidity or prolong pregnancy to term however it did reduce the number of women delivering within 2 days by 40%. This 48 hour window is the only reason for the use of tocolytics.
Choice of tocolytic (NICE)
1st line: Nifedipine
2nd line: Oxytocin receptor antagonists e.g. atosiban -

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: Zavanell manoeuvre
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. -

Pregnant patients are at higher risk of thromboembolism due to a hypercoagulable state. Which of the following clotting factors reduces during pregnancy?
Your Answer: Factor XI
Explanation:Pregnancy is a hypercoagulable state, which means that risk of thromboembolism is increased. The main reason is an increase in clotting factors II, factor VII, fibrinogen, factor X and factor XII, whereas factors XI and factor XIII are reduced. Naturally occurring anticoagulants i.e. protein C and protein S are both decreased thus increasing the risk of thrombus formation.

A 29 year old patient presents due to the sensation of reduced fetal movements (RFM). From what gestation is CTG assessment of RFM advised?
Your Answer:
Correct Answer: 28+0 weeks
Explanation:The cardiotocograph (CTG) is a continuous tracing of the fetal heart rate used to assess fetal wellbeing. The Doppler effect detects fetal heart motion and allows the interval between successive beats to be measured, thereby allowing a continuous assessment of fetal heart rate. The mother perceives the fetal movement by the 18-20 week of gestation and these increase until the 32 week. A mother should under go CTG if the fetal movements are reduced by the 28 week of gestation.

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:
Correct 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.

Regarding the diagnosis of Gestational Diabetes which of the following tests is recommended by the WHO for diagnosis?
Your Answer:
Correct Answer: 75g OGTT with 2 hour glucose
Explanation:Gestational diabetes (GDM) occurs in 2–9 per cent of all pregnancies. Screening for diabetes in pregnancy can be justify ed to diagnose previously unrecognized cases of pre-existing diabetes and to identify a group of women who are at risk of developing NIDDM later in life. No single screening test has been shown to be perfect in terms of high sensitivity and specific city for gestational diabetes. Urinary glucose is unreliable, and most screening tests now rely on blood glucose estimation, with an oral 75g glucose tolerance test commonly used. The aim of glucose control is to keep fasting levels between 3.5 and 5.5 mmol/L and postprandial levels 7.1 mmol/L, with insulin treatment usually indicated outside these ranges.

You are asked to review a patient. They have attended for a scan at 13 weeks following a positive pregnancy test. The patient has had 2 previous pregnancies for which she opted for termination on both occasions. The scan shows no identifiable fetal tissue or gestational sac and you note the radiologist has reported a 'bunch of grapes sign'. What is the likely diagnosis?
Your Answer:
Correct Answer: Complete molar pregnancy
Explanation:Gestational trophoblastic disorder is abnormal conception that is characterised by swollen and oedematous villi with proliferation of the trophoblasts. In a complete mole there is absence of fetal tissue, there is diffuse proliferation of trophoblastic tissue around hydropic villi and on USG it appears as a bunch of grapes or snow storm appearance.

A 56 year old lady presents with a vulval itch and discolouration. A biopsy conforms Lichen Sclerosis (LS). What is the risk of developing squamous cell carcinoma compared to patients with a normal vulval biopsy?
Your Answer:
Correct Answer:
Explanation:Lichen Sclerosis is a destructive inflammatory condition that effects the anogenital region of women. It effects around 1 in 300 women. It destroys the subdermal layers of the skin resulting in hyalinization of the skin leading to parchment paper appearance of the skin. It is associated with vulval cancer and it is estimated that the risk of developing vulval cancer after lichen sclerosis is around 3-5%.

Which of the following hormones is produced by the hypothalamus in response to breastfeeding?
Your Answer:
Correct Answer: Oxytocin
Explanation:Nipple stimulation during breastfeeding triggers the production of oxytocin from the hypothalamus and its subsequent release from the posterior pituitary gland. The hormone causes the myoepithelial cells of the breast to contract causing milk to flow through the ducts.
Ergometrine and Prostaglandin E2 are used during labour to control uterine bleeding after delivery, or ripen the cervix, while Atosiban is an oxytocin antagonist.
Antidiuretic hormone is also released from the posterior pituitary, and acts on the kidneys to decrease fluid excretion.
