1A 32-year-old primigravida at 32 weeks of gestation presents with severe headache, visual scotomata, and blood pressure of 175/115 mmHg. Urinalysis shows 3+ proteinuria. The patient has a documented medical history of moderate-to-severe bronchial asthma. Which of the following intravenous antihypertensive agents is the most appropriate first-line choice for acute blood pressure control in this patient?

A.Intravenous Hydralazine bolus

B.Intravenous Labetalol bolus

C.Intravenous Sodium Nitroprusside infusion

D.Oral Atenolol tablet

Explanation: Intravenous hydralazine (5-10 mg IV over 2 minutes, repeatable after 20 minutes) is a direct arteriolar vasodilator and the preferred first-line agent in this patient because labetalol is contraindicated due to her history of bronchial asthma (beta-blockers can trigger severe bronchospasm). The target is to safely lower systolic BP to 140-150 mmHg and diastolic BP to 90-100 mmHg to prevent maternal intracerebral hemorrhage while preserving uteroplacental perfusion.

2A 24-year-old woman in active labor at 38 weeks develops a generalized tonic-clonic eclamptic seizure. A loading dose of intravenous magnesium sulfate is administered. During the continuous maintenance infusion, the nurse notes absent patellar deep tendon reflexes and a respiratory rate of 9 breaths per minute. Which of the following is the most appropriate immediate intervention?

A.Administer intravenous Diazepam 10 mg immediately

B.Stop magnesium sulfate infusion and administer 10% Calcium Gluconate 10 mL intravenously over 3-5 minutes

C.Increase intravenous fluid rate to accelerate renal clearance

D.Intubate the patient immediately before administering any pharmacologic antidote

Explanation: Loss of deep tendon reflexes (occurring at serum magnesium levels > 4-5 mmol/L or 9-12 mg/dL) followed by respiratory depression (< 12 breaths/min at > 5-6 mmol/L) are classic signs of magnesium sulfate toxicity. The immediate management is to stop the magnesium infusion and administer the specific antidote, 10% calcium gluconate (1 g IV over 3-5 minutes), which competitively antagonizes magnesium at the neuromuscular junction.

3A 29-year-old multipara at 29+4 weeks of gestation is admitted with severe right upper quadrant pain, nausea, and headache. Laboratory investigations reveal: Platelet count 38,000/microL, AST 310 IU/L, ALT 280 IU/L, total bilirubin 2.4 mg/dL, and LDH 890 IU/L. Fetal heart rate monitoring is reassuring. What is the most appropriate definitive management for this patient?

A.Expectant management with corticosteroids for 48 hours to achieve complete fetal lung maturity

B.Plasmapheresis combined with high-dose intravenous methylprednisolone

C.Maternal stabilization, platelet transfusion if indicated, magnesium sulfate seizure prophylaxis, and prompt delivery

D.Immediate exploratory laparotomy for suspected hepatic rupture

Explanation: This patient has severe HELLP syndrome with profound thrombocytopenia (< 50,000/microL) and hepatic dysfunction. After maternal stabilization (airway, blood pressure control, magnesium sulfate neuroprotection/seizure prophylaxis, and correction of coagulopathy), prompt delivery is the only definitive treatment, as delaying delivery in advanced HELLP significantly increases maternal mortality, liver rupture, and abruption.

4A 28-year-old woman with a monochorionic diamniotic (MCDA) twin pregnancy undergoes a routine ultrasound at 20 weeks of gestation. Imaging reveals twin A (donor) with severe oligohydramnios (deepest vertical pool [DVP] 1.4 cm) and an empty, non-visualized bladder. Twin B (recipient) has polyhydramnios (DVP 9.2 cm) and an enlarged bladder. Umbilical artery and ductus venosus Doppler waveforms are normal in both twins. What is the Quintero stage and the definitive gold standard treatment?

A.Quintero Stage I; Serial selective reduction

B.Quintero Stage IV; Emergency delivery by cesarean section

C.Quintero Stage III; Serial therapeutic amnioreduction

D.Quintero Stage II; Fetoscopic laser photocoagulation of placental communicating vessels

Explanation: Quintero Stage II Twin-to-Twin Transfusion Syndrome (TTTS) is defined by the classic polyhydramnios/oligohydramnios sequence with persistent non-visualization of the donor twin's bladder on ultrasound, but without abnormal Doppler findings (which would denote Stage III). The international gold standard first-line treatment for TTTS from 16 to 26 weeks is fetoscopic laser photocoagulation of anastomotic placental vessels (Solomon technique).

5A monochorionic diamniotic twin pregnancy at 26 weeks is monitored for twin anemia-polycythemia sequence (TAPS). Which of the following Doppler ultrasonography criteria confirms the antenatal diagnosis of TAPS?

A.Middle cerebral artery peak systolic velocity (MCA-PSV) > 1.5 MoM in the donor and < 1.0 MoM in the recipient, in the absence of polyhydramnios-oligohydramnios sequence

B.Deepest vertical pool < 2 cm in donor and > 8 cm in recipient without Doppler discrepancies

C.Umbilical artery pulsatility index > 95th percentile in both twins with normal MCA velocities

D.Absent end-diastolic velocity in the umbilical artery of the larger twin

Explanation: Twin Anemia-Polycythemia Sequence (TAPS) is characterized by slow inter-twin blood transfusion through minuscule arteriovenous anastomoses (< 1 mm). It is diagnosed antenatally when MCA-PSV is elevated (> 1.5 MoM, indicating fetal anemia) in the donor twin and decreased (< 1.0 or < 0.8 MoM, indicating polycythemia) in the recipient twin, without the classic amniotic fluid volume discordance of TTTS.

6A 26-year-old primigravida at 29 weeks of gestation is diagnosed with severe early-onset fetal growth restriction. Serial Doppler monitoring shows persistent absent end-diastolic flow in the umbilical artery. Over the next 48 hours, targeted Doppler assessment of the ductus venosus demonstrates a reversed 'a-wave' during atrial contraction. What is the clinical significance of this finding and the required management?

A.It represents physiological compensation; continue outpatient weekly biophysical profile

B.It indicates severe fetal acidemia, myocardial compromise, and imminent risk of stillbirth; proceed with delivery after antenatal corticosteroid coverage

C.It indicates fetal brain-sparing; repeat Doppler studies in 2 weeks

D.It represents umbilical cord compression; perform immediate amnioinfusion

Explanation: The ductus venosus reflects right ventricular afterload and central venous pressure. Progression to an absent or reversed 'a-wave' during atrial systole indicates severe fetal acidemia, myocardial decompensation, and an imminent risk of intrauterine fetal demise within 48-72 hours. In early FGR, this is the definitive trigger for immediate delivery after administering antenatal corticosteroids and magnesium sulfate for neuroprotection.

7A 31-year-old woman at 35 weeks of gestation is evaluated for late-onset fetal growth restriction. Fetal abdominal circumference is at the 4th percentile. Umbilical artery Doppler pulsatility index is normal (50th percentile). However, Middle Cerebral Artery (MCA) pulsatility index is low (< 5th percentile), resulting in a Cerebroplacental Ratio (CPR) < 1.0. What is the clinical interpretation of this Doppler pattern?

A.Normal hemodynamic adaptation requiring no change in standard antenatal care

B.Fetal cranial arteriovenous malformation

C.Fetal hypoxia with cerebral redistribution ('brain-sparing effect') associated with increased risk of intrapartum distress

D.False-positive artifact that should be disregarded because the umbilical artery Doppler is normal

Explanation: In late-onset fetal growth restriction (> 32 weeks), the umbilical artery Doppler is frequently normal because placental vascular involvement is mild. Instead, hemodynamic redistribution occurs, causing vasodilation of the fetal cerebral circulation (low MCA-PI and CPR < 1.0 or < 5th percentile). This 'brain-sparing' phenomenon signifies fetal hypoxia and is strongly associated with intrapartum fetal distress, emergency cesarean section, and neonatal acidosis, prompting planned delivery at 37 weeks.

8A 25-year-old primigravida who is RhD-negative with a negative indirect Coombs antibody screen presents at 28 weeks of gestation for routine antenatal care. Her partner is known to be RhD-positive. What is the standard evidence-based prophylactic management to prevent Rh alloimmunization?

A.Weekly amniocentesis for Delta OD450 spectrophotometric measurement

B.No prophylaxis until immediate postpartum confirmation of infant Rh status

C.Administration of oral Dexamethasone to suppress maternal antibody synthesis

D.Administration of 300 mcg (1500 IU) of Anti-D immunoglobulin at 28 weeks

Explanation: Standard routine antenatal anti-D prophylaxis (RAADP) requires administering 300 mcg (1500 IU) of Anti-D immunoglobulin at 28 weeks of gestation (or a two-dose regimen of 500 IU at 28 and 34 weeks) to non-sensitized RhD-negative women. This suppresses maternal immune response to occult fetomaternal hemorrhage occurring in the third trimester.

9A 30-year-old RhD-negative woman (Gravida 3, Para 2) is found to have anti-D alloantibodies with a critical titer of 1:64 at 24 weeks of gestation. Serial Middle Cerebral Artery Peak Systolic Velocity (MCA-PSV) Doppler shows a value of 1.65 multiples of the median (MoM). What is the next most appropriate step in management?

A.Perform fetal blood sampling (cordocentesis) with preparation for intrauterine intravascular red cell transfusion

B.Perform emergent cesarean delivery under general anesthesia

C.Administer a large dose of intramuscular Anti-D immunoglobulin

D.Repeat the MCA-PSV Doppler in 4 weeks

Explanation: An MCA-PSV > 1.5 MoM has a sensitivity of ~95% for detecting moderate-to-severe fetal anemia in red cell alloimmunized pregnancies (caused by decreased blood viscosity and hyperdynamic circulation). At 24 weeks, the standard management is diagnostic cordocentesis (fetal blood sampling) to determine the exact fetal hematocrit, with immediate intravascular intrauterine transfusion of O-negative, CMV-negative, irradiated packed red blood cells.

10According to the International Association of Diabetes and Pregnancy Study Groups (IADPSG) and WHO criteria, what are the plasma glucose threshold values on a 75 g 2-hour Oral Glucose Tolerance Test (OGTT) for diagnosing Gestational Diabetes Mellitus (GDM)?

A.Fasting >= 7.0 mmol/L (126 mg/dL), 1-hour >= 11.1 mmol/L (200 mg/dL), 2-hour >= 11.1 mmol/L (200 mg/dL)

B.Fasting >= 5.1 mmol/L (92 mg/dL), 1-hour >= 10.0 mmol/L (180 mg/dL), 2-hour >= 8.5 mmol/L (153 mg/dL)

C.Fasting >= 5.8 mmol/L (105 mg/dL), 1-hour >= 10.6 mmol/L (190 mg/dL), 2-hour >= 9.2 mmol/L (165 mg/dL)

D.Fasting >= 6.1 mmol/L (110 mg/dL), 1-hour >= 8.0 mmol/L (144 mg/dL), 2-hour >= 7.8 mmol/L (140 mg/dL)

Explanation: Under the one-step 75 g OGTT (IADPSG/WHO criteria), GDM is diagnosed if any ONE of the following cutoffs is met or exceeded: Fasting plasma glucose >= 5.1 mmol/L (92 mg/dL), 1-hour glucose >= 10.0 mmol/L (180 mg/dL), or 2-hour glucose >= 8.5 mmol/L (153 mg/dL). These thresholds are based on the HAPO study correlating maternal glycemia with adverse perinatal outcomes.
