Question 51: A 26-year-old woman attends the antenatal clinic at 32 weeks gestation. She was diagnosed with gestational hypertension at 30 weeks and started on labetalol 200 mg twice daily. Today her blood pressure is 136/84 mmHg. She reports no symptoms. Urinalysis is negative for protein. Bloods show: Hb 115 g/L, platelets 180 × 10⁹/L, ALT 25 U/L, creatinine 68 μmol/L. Fetal growth scan shows estimated fetal weight on 50th centile with normal liquor volume. What is the most appropriate ongoing management plan?
A. Continue current management with blood pressure and urine monitoring twice weekly (Correct Answer)
B. Increase labetalol dose to 400 mg twice daily to achieve target BP <130/80 mmHg
C. Reduce labetalol to 100 mg twice daily as blood pressure is well controlled
D. Admit for inpatient monitoring and daily blood tests
E. Arrange delivery at 34 weeks to prevent progression to pre-eclampsia
Explanation: ***Continue current management with blood pressure and urine monitoring twice weekly***
- The patient's blood pressure of **136/84 mmHg** is well-controlled on **labetalol**, falling within the recommended target range for **gestational hypertension** (typically <140/90 mmHg, often aiming for <135/85 mmHg).
- Ongoing **blood pressure and urine monitoring twice weekly** is crucial for stable gestational hypertension to detect early signs of progression to **pre-eclampsia**, which is characterized by new-onset proteinuria.
*Increase labetalol dose to 400 mg twice daily to achieve target BP <130/80 mmHg*
- The current blood pressure is already within the acceptable range; **aggressive lowering below 130/80 mmHg** is generally not required and may risk **impaired placental perfusion**.
- An increase in dose would only be considered if blood pressure consistently exceeded **140/90 mmHg** or specific stricter targets were indicated due to other complications.
*Reduce labetalol to 100 mg twice daily as blood pressure is well controlled*
- Reducing the current medication dose for **well-controlled hypertension** can lead to a **rebound in blood pressure** and loss of control, increasing the risk of complications.
- Medication should be maintained at an effective dose unless there are signs of **hypotension** or significant adverse effects.
*Admit for inpatient monitoring and daily blood tests*
- Inpatient admission is typically reserved for cases of **severe hypertension** (BP ≥160/110 mmHg), suspected or confirmed **pre-eclampsia** with features of severe disease (e.g., proteinuria, organ dysfunction), or signs of **fetal compromise**.
- This patient is asymptomatic, with normal blood tests (platelets, ALT, creatinine) and fetal well-being, making outpatient management appropriate.
*Arrange delivery at 34 weeks to prevent progression to pre-eclampsia*
- Delivery at **34 weeks gestation** would result in **prematurity** and is only indicated for severe, uncontrolled pre-eclampsia, significant fetal compromise, or other critical maternal conditions.
- For women with stable gestational hypertension and no signs of pre-eclampsia, continuation of pregnancy until **37 weeks gestation** is generally recommended to optimize neonatal outcomes.
Question 52: A 35-year-old woman with well-controlled gestational diabetes on insulin therapy is reviewed at 39 weeks gestation. Her pregnancy has been otherwise uncomplicated with normal fetal growth on serial ultrasound scans and consistently reassuring cardiotocography. She asks about the timing of delivery. According to current UK guidance, what is the most appropriate advice regarding timing of birth?
A. Offer induction of labour between 37+0 and 38+6 weeks
B. Offer induction of labour between 38+0 and 39+6 weeks (Correct Answer)
C. Allow spontaneous labour up to 41 weeks with increased fetal monitoring
D. Recommend elective caesarean section at 38 weeks
E. Offer induction of labour between 39+0 and 40+6 weeks
Explanation: ***Offer induction of labour between 38+0 and 39+6 weeks***
- For women with **gestational diabetes** managed with **insulin** or oral medication in an otherwise uncomplicated pregnancy, induction is recommended between **38+0 and 39+6 weeks**.
- This timing balances the increased risk of **stillbirth** and placental insufficiency against the risks of **iatrogenic prematurity**.
*Offer induction of labour between 37+0 and 38+6 weeks*
- This earlier window was previously suggested but older **NICE guidelines** have been refined; it is usually reserved for those with **poor glycaemic control** or other co-morbidities.
- Induction before 38 weeks increases the risk of **neonatal respiratory distress** in pregnancies that are otherwise progressing normally.
*Allow spontaneous labour up to 41 weeks with increased fetal monitoring*
- Waiting until 41 weeks is inappropriate for patients on **insulin** due to the significantly elevated risk of **perinatal mortality**.
- Spontaneous labour up to 40+6 weeks is only typically offered to women with **diet-controlled** gestational diabetes and no other complications.
*Recommend elective caesarean section at 38 weeks*
- **Caesarean section** is not routinely recommended based solely on a diagnosis of gestational diabetes.
- Mode of delivery should be based on **obstetric indications** or maternal preference, with **vaginal delivery** being the primary aim for most.
*Offer induction of labour between 39+0 and 40+6 weeks*
- Waiting until after 40 weeks increases the risk of **macrosomia** and associated birth trauma like **shoulder dystocia** in diabetic pregnancies.
- While some guidelines suggest up to 40+6 for diet-controlled GDM, those on **insulin** require earlier intervention to mitigate metabolic risks.
Question 53: A 33-year-old woman presents to the emergency department at 38 weeks gestation with sudden onset severe headache, visual disturbances with flashing lights, and epigastric pain. She has had an uncomplicated pregnancy until now. Blood pressure is 168/110 mmHg. Urinalysis shows 3+ protein. Blood tests reveal: platelets 95 × 10⁹/L, ALT 180 U/L, AST 195 U/L, creatinine 110 μmol/L. What is the most appropriate immediate management?
A. Commence IV magnesium sulphate and prepare for delivery (Correct Answer)
B. Administer oral labetalol and observe for 24 hours
C. Give IV hydralazine and arrange urgent CT head
D. Start oral nifedipine and await senior review
E. Administer IV labetalol and perform urgent Doppler studies
Explanation: ***Commence IV magnesium sulphate and prepare for delivery***
- The patient's symptoms (severe headache, visual disturbances, epigastric pain), severe hypertension (168/110 mmHg), proteinuria, and abnormal lab results (thrombocytopenia and elevated liver enzymes indicative of **HELLP syndrome**) point to **severe pre-eclampsia** with features of impending eclampsia, necessitating immediate **seizure prophylaxis** with IV magnesium sulphate.
- At **38 weeks gestation**, the pregnancy is at term, and **delivery** is the definitive and most appropriate immediate management to resolve severe pre-eclampsia and prevent progression to eclampsia or other severe maternal and fetal complications.
*Administer oral labetalol and observe for 24 hours*
- **Oral antihypertensives** like labetalol are generally too slow and insufficient for the rapid blood pressure control required in **severe pre-eclampsia** with neurological symptoms.
- **Observation for 24 hours** is inappropriate and unsafe given the life-threatening nature of the condition at term, as it risks progression to eclampsia, placental abruption, or further HELLP syndrome complications.
*Give IV hydralazine and arrange urgent CT head*
- While **IV hydralazine** can effectively lower blood pressure, it does not provide the crucial **seizure prophylaxis** that **magnesium sulphate** offers and is immediately needed for this patient.
- An **urgent CT head** is not the first-line immediate management unless there are focal neurological deficits or persistent altered mental status *after* a seizure, but stabilizing the patient and preventing seizures is paramount.
*Start oral nifedipine and await senior review*
- **Oral nifedipine** is typically reserved for less severe hypertension or as an adjunct, and it lacks the rapid action needed for this patient's severe presentation.
- **Awaiting senior review** without initiating definitive treatment like magnesium sulphate and preparing for delivery represents an unacceptable delay in a critical obstetric emergency.
*Administer IV labetalol and perform urgent Doppler studies*
- **IV labetalol** will address hypertension but does not provide the essential **seizure prophylaxis** required, which is a major immediate risk for this patient.
- While **Doppler studies** assess fetal well-being, at **38 weeks gestation** with severe maternal compromise, the priority shifts to **maternal stabilization** and immediate delivery, as fetal viability is high and further delay is risky.
Question 54: A 29-year-old primigravida at 24 weeks gestation undergoes oral glucose tolerance test (OGTT) following detection of glycosuria at her routine antenatal visit. Results show fasting glucose 5.8 mmol/L and 2-hour glucose 8.6 mmol/L. She has a BMI of 28 kg/m² and no family history of diabetes. How should she be managed?
A. Reassure and repeat OGTT at 28 weeks
B. Diagnose gestational diabetes and commence diet and lifestyle modifications with home glucose monitoring (Correct Answer)
C. Commence metformin immediately without dietary intervention
D. Refer to diabetic specialist team but no immediate intervention needed
E. Diagnose impaired glucose tolerance and perform HbA1c testing
Explanation: ***Diagnose gestational diabetes and commence diet and lifestyle modifications with home glucose monitoring***
- According to **NICE guidelines**, gestational diabetes (GDM) is diagnosed if fasting glucose is **≥5.6 mmol/L** or 2-hour glucose is **≥7.8 mmol/L**; this patient exceeds both thresholds.
- Initial management for GDM involves **dietary modification**, exercise, and **self-monitoring of blood glucose** (SMBG) to establish if glycemic targets can be met without medication.
*Reassure and repeat OGTT at 28 weeks*
- Reassurance is inappropriate because the patient currently meets the **diagnostic criteria** for GDM based on the 24-week test results.
- Delaying management until 28 weeks increases the risk of **macrosomia**, polyhydramnios, and other **gestational complications**.
*Commence metformin immediately without dietary intervention*
- First-line management for GDM is typically a trial of **diet and exercise** for 1–2 weeks before introducing pharmacological agents.
- **Metformin** or insulin is indicated only if blood glucose targets are not achieved through lifestyle changes or if fasting levels are significantly elevated (e.g., >7.0 mmol/L).
*Refer to diabetic specialist team but no immediate intervention needed*
- While referral to a **joint diabetes-antenatal clinic** is necessary, intervention should start immediately with education and glucose monitoring.
- Delayed intervention neglects the period of **hyperglycemia**, which impacts fetal growth and maternal health.
*Diagnose impaired glucose tolerance and perform HbA1c testing*
- **HbA1c** is not recommended for diagnosing GDM as it is unreliable due to increased **red blood cell turnover** and physiological changes in pregnancy.
- The term "impaired glucose tolerance" is not the standard clinical diagnosis in pregnancy; the results clearly define **Gestational Diabetes Mellitus**.
Question 55: A 37-year-old woman presents to the antenatal day unit at 31 weeks gestation with reduced fetal movements. This is her second pregnancy; her first child was delivered by emergency caesarean section for fetal distress at 39 weeks. Her booking BMI was 32 kg/m². Blood pressure today is 142/88 mmHg. Urinalysis shows trace protein. Cardiotocography is reassuring. What is the most appropriate initial investigation to assess for potential complications?
A. Umbilical artery Doppler ultrasound
B. Fetal growth scan with estimated fetal weight and amniotic fluid assessment (Correct Answer)
C. 24-hour urine protein collection
D. Maternal blood tests including urea, creatinine and liver function
E. Biophysical profile score
Explanation: ***Fetal growth scan with estimated fetal weight and amniotic fluid assessment***
- In a patient with **reduced fetal movements** and multiple risk factors (BMI >30, age >35, previous C-section), the primary concern is identifying **fetal growth restriction (FGR)** or **placental insufficiency**.
- Assessing **estimated fetal weight (EFW)** and **amniotic fluid volume (AFV)** is the gold standard initial step to evaluate chronic fetal wellbeing and potential complications like **oligohydramnios**.
*Umbilical artery Doppler ultrasound*
- This is usually performed as a secondary measure if the **fetal growth scan** reveals a small-for-gestational-age fetus or other growth concerns.
- While useful for assessing **placental resistance**, it does not provide the primary biometric data required to diagnose **growth restriction** itself.
*24-hour urine protein collection*
- This investigation is used to quantify protein in suspected **pre-eclampsia**, but a trace protein result and blood pressure of 142/88 mmHg do not yet meet diagnostic criteria.
- The immediate priority in the context of **reduced fetal movements** is the assessment of the fetus rather than definitive proteinuria quantification.
*Maternal blood tests including urea, creatinine and liver function*
- These tests screen for multi-organ involvement in **pre-eclampsia**, which is a consideration given her blood pressure and BMI.
- However, these are secondary to the **ultrasound assessment** of fetal growth and liquid when the presenting complaint is decreased movement.
*Biophysical profile score*
- The **Biophysical profile (BPP)** is a comprehensive assessment that includes CTG and ultrasound parameters, but it is time-consuming and often reserved for specific high-risk scenarios.
- Current guidelines favor a **growth scan** and **liquor assessment** as the standard first-line anatomical and physiological evaluation for reduced movements.
Question 56: A 32-year-old woman with pre-existing chronic hypertension presents for pre-pregnancy counselling. She is currently taking ramipril 5 mg daily, which provides excellent blood pressure control. She has no other medical conditions and her renal function is normal. What advice should be given regarding her antihypertensive medication in pregnancy?
A. Continue ramipril throughout pregnancy as blood pressure control is optimal
B. Switch to labetalol before conception or as soon as pregnancy is confirmed (Correct Answer)
C. Continue ramipril in the first trimester then switch to nifedipine
D. Stop all antihypertensive medication and monitor blood pressure closely
E. Switch to atenolol as it is safer in pregnancy than ramipril
Explanation: ***Switch to labetalol before conception or as soon as pregnancy is confirmed***- **ACE inhibitors** like ramipril are strictly **contraindicated** in pregnancy due to associations with **major congenital malformations**, fetal renal failure, and oligohydramnios.- **Labetalol**, a combined alpha/beta-blocker, is a recommended first-line, safe antihypertensive for managing **chronic hypertension** during pregnancy.*Continue ramipril throughout pregnancy as blood pressure control is optimal*- Ramipril exposure during the second and third trimesters can lead to severe adverse fetal outcomes such as **oligohydramnios**, **fetal skull hypoplasia**, and **neonatal anuria/renal failure**.- The risks of **teratogenicity** and potential fetal demise far outweigh any maternal benefit of maintaining ramipril for blood pressure control.*Continue ramipril in the first trimester then switch to nifedipine*- Although the highest risk for severe fetal renal complications with ACE inhibitors is in the second and third trimesters, they should ideally be avoided from **conception**.- Guidelines recommend transitioning to safe alternatives like **nifedipine** or labetalol **before** conception or as soon as pregnancy is confirmed to avoid any early gestational exposure.*Stop all antihypertensive medication and monitor blood pressure closely*- Discontinuing antihypertensive medication in a patient with pre-existing **chronic hypertension** significantly increases the risk of **maternal stroke**, placental abruption, and **preeclampsia**.- Maintaining adequate blood pressure control is crucial throughout pregnancy to ensure optimal maternal health and fetal development.*Switch to atenolol as it is safer in pregnancy than ramipril*- **Atenolol** is associated with an increased risk of **intrauterine growth restriction (IUGR)** and fetal bradycardia, and is generally not a preferred first-line agent in pregnancy.- While considered safer than ACE inhibitors, **labetalol**, **nifedipine**, and **methyldopa** are generally preferred due to a more favorable safety profile.
Question 57: A 30-year-old woman with gestational diabetes is seen at 34 weeks gestation. She has been managing her condition with diet alone since diagnosis at 28 weeks. Her recent capillary blood glucose readings show: fasting 5.4 mmol/L, 1-hour post-breakfast 8.2 mmol/L, 1-hour post-lunch 7.8 mmol/L, 1-hour post-dinner 8.5 mmol/L. She reports good dietary compliance. What is the most appropriate next step in her management?
A. Continue diet alone and review in 2 weeks
B. Start metformin 500 mg once daily (Correct Answer)
C. Start insulin therapy
D. Start metformin 500 mg twice daily
E. Arrange urgent delivery within 48 hours
Explanation: ***Start metformin 500 mg once daily***- According to **NICE guidelines**, if blood glucose targets (fasting <5.3 mmol/L and 1-hour postprandial <7.8 mmol/L) are not met with diet alone, **metformin** should be offered as first-line pharmacological treatment.- This patient's **fasting (5.4 mmol/L)** and **postprandial (8.2/8.5 mmol/L)** readings are above targets, and it is standard practice to start with a low dose like **500 mg once daily** and titrate upward.*Continue diet alone and review in 2 weeks*- Pharmacological intervention is required because the patient is **not meeting glycemic targets** despite reporting good dietary compliance.- Delaying treatment for 2 weeks poses an unnecessary risk of **macrosomia** and other gestational diabetes-related complications.*Start insulin therapy*- **Insulin** is usually reserved as second-line treatment if targets are not met with metformin or if metformin is **contraindicated** or not tolerated.- Immediate insulin start is typically only indicated if the fasting glucose at diagnosis is significantly elevated (**>= 7.0 mmol/L**) or if there are signs of **fetal macrosomia**.*Start metformin 500 mg twice daily*- While the patient requires metformin, the standard clinical protocol is to initiate treatment at **500 mg once daily** to minimize **gastrointestinal side effects**.- Increasing to a twice-daily dose occurs during the **titration phase** based on subsequent blood glucose monitoring results.*Arrange urgent delivery within 48 hours*- There is no clinical indication for **preterm delivery** at 34 weeks based solely on mildly elevated blood glucose levels.- Delivery is usually planned between **37+0 and 38+6 weeks** for women with gestational diabetes, unless there are acute fetal or maternal complications.
Question 58: A 34-year-old woman attends her first antenatal appointment at 18 weeks gestation. She has no significant medical history. Her BMI is 22 kg/m². Blood pressure is 118/76 mmHg. She asks about the routine blood tests performed in pregnancy. Which autoantibody screening is routinely offered to all pregnant women in the UK antenatal care programme?
A. Anti-nuclear antibodies (ANA)
B. Anti-thyroid peroxidase (anti-TPO) antibodies
C. Anti-red cell antibodies (Correct Answer)
D. Anti-phospholipid antibodies
E. Anti-double stranded DNA antibodies
Explanation: ***Anti-red cell antibodies***
- Screening for **blood group** and **anti-red cell antibodies** is a mandatory part of the UK routine antenatal care, performed at booking and 28 weeks gestation.
- This is critical for identifying **Rhesus D incompatibility** and other antibodies that could cause **haemolytic disease of the fetus and newborn (HDFN)**.
*Anti-nuclear antibodies (ANA)*
- **ANA** screening is not a routine test and is only indicated if there is clinical suspicion of **systemic lupus erythematosus (SLE)** or other connective tissue diseases.
- Routine testing would lead to high rates of false positives, as low-titer ANA can be seen in healthy individuals.
*Anti-thyroid peroxidase (anti-TPO) antibodies*
- Routine screening for **TPO antibodies** is not recommended in the UK; thyroid function is only assessed if the patient is symptomatic or has a **pre-existing thyroid condition**.
- While anti-TPO is associated with **postpartum thyroiditis**, it does not meet the criteria for universal population screening in pregnancy.
*Anti-phospholipid antibodies*
- Testing for **lupus anticoagulant** or **anti-cardiolipin antibodies** is reserved for women with specific histories, such as **recurrent miscarriage** or previous venous thromboembolism.
- These are not screened in a low-risk patient with no significant medical history like the woman in this scenario.
*Anti-double stranded DNA antibodies*
- **Anti-dsDNA** is a highly specific marker for SLE and is used for monitoring **disease activity** rather than as a general screening tool.
- It is only requested if the patient has a positive **ANA** or clinical features suggestive of active **lupus**.
Question 59: A 27-year-old woman with well-controlled gestational diabetes on metformin presents at 40 weeks gestation. She has been offered induction of labour. She asks why she cannot wait for spontaneous labour beyond 40 weeks as she has read that induction increases the risk of caesarean section. Her fetal growth scans have been normal and her most recent estimated fetal weight is 3.6 kg (50th centile). Her blood glucose control has been excellent with all values within target range. What is the most appropriate counselling regarding timing of delivery?
A. She can safely await spontaneous labour until 42 weeks with standard monitoring
B. Induction should be offered by 40+6 weeks due to increased risk of stillbirth with gestational diabetes (Correct Answer)
C. Elective caesarean section is recommended at 40 weeks due to gestational diabetes
D. She can await spontaneous labour until 41 weeks then should have induction
E. Immediate induction is required today as she has reached 40 weeks with gestational diabetes
Explanation: ***Induction should be offered by 40+6 weeks due to increased risk of stillbirth with gestational diabetes***- **NICE guidelines** recommend that women with **gestational diabetes** should be offered birth (induction or elective cesarean) between **38+0 and 40+6 weeks**.- Delivery is recommended by this time because gestational diabetes is associated with an increased risk of **late stillbirth** and other metabolic complications as the pregnancy progresses.*She can safely await spontaneous labour until 42 weeks with standard monitoring*- Awaiting spontaneous labor until **42 weeks** is inappropriate for diabetic patients due to the significantly elevated **risk of intrauterine fetal death** beyond 41 weeks.- Standard post-dates monitoring is insufficient to mitigate the specific **metabolic risks** associated with gestational diabetes in late pregnancy.*Elective caesarean section is recommended at 40 weeks due to gestational diabetes*- **Elective caesarean section** is generally only offered if there are specific complications such as **macrosomia** (EFW >4.5kg) or a previous history of shoulder dystocia.- For a patient with a **normal estimated fetal weight** (3.6kg) and good control, **induction of labor** is the preferred method for planned delivery.*She can await spontaneous labour until 41 weeks then should have induction*- While 41 weeks is close to the limit, the specific guidelines state delivery should be offered no later than **40+6 weeks** to optimize safety.- Recommending 41 weeks ignores the established clinical evidence that **stillbirth risk** rises more sharply in diabetic pregnancies after the 40th week.*Immediate induction is required today as she has reached 40 weeks with gestational diabetes*- While **induction** is offered from **38+0 weeks**, it is not immediately mandatory at **40 weeks** if the patient is well-controlled and fetal growth is normal.- The recommendation is to offer delivery by **40+6 weeks**, providing a window for discussion and preparation rather than requiring immediate intervention at 40 weeks exact.
Question 60: A 38-year-old woman in her fourth pregnancy presents to the antenatal clinic at 20 weeks gestation. She has previously had three normal vaginal deliveries. Her booking blood pressure at 10 weeks was 124/78 mmHg. Today her blood pressure is 156/98 mmHg on two readings 30 minutes apart. She is asymptomatic. Urinalysis is negative for protein. Blood tests show: Hb 125 g/L, platelets 256 × 10⁹/L, ALT 24 IU/L, creatinine 64 μmol/L. Which diagnosis best fits this clinical presentation?
A. Essential hypertension unmasked by pregnancy
B. Chronic hypertension
C. Gestational hypertension (Correct Answer)
D. Pre-eclampsia
E. White coat hypertension
Explanation: ***Gestational hypertension***- This is defined as new-onset **hypertension (≥140/90 mmHg)** occurring **after 20 weeks** of gestation without **proteinuria** or signs of end-organ damage.- The patient’s blood pressure was normal at 10 weeks, and her recent readings at 20 weeks show elevation with **negative protein** and normal lab results (ALT, creatinine, platelets).*Essential hypertension unmasked by pregnancy*- This refers to pre-existing hypertension that may not have been documented prior to pregnancy but becomes apparent during the clinical visits.- Since her **booking blood pressure** at 10 weeks was normal, and BP typically dips in the first trimester, a normal reading then makes this less likely than gestational hypertension.*Chronic hypertension*- Chronic hypertension is diagnosed if the high blood pressure is present **before pregnancy** or is detected **before 20 weeks** of gestation.- This patient’s normal BP at 10 weeks (124/78 mmHg) effectively excludes a diagnosis of **pre-existing** or chronic hypertension.*Pre-eclampsia*- Pre-eclampsia requires new-onset hypertension after 20 weeks plus **proteinuria** or evidence of **maternal organ dysfunction** (e.g., low platelets, high ALT).- This patient is **asymptomatic**, has no proteinuria on urinalysis, and her blood tests show normal **liver and renal function**.*White coat hypertension*- This occurs when BP is elevated in a clinical setting but normal during **ambulatory or home monitoring**.- While possible, the standard clinical diagnosis for new-onset clinical hypertension occurring exactly at the 20-week threshold in a previously normotensive woman is **gestational hypertension**.
