A 28-year-old primigravida at 34 weeks gestation presents to the antenatal clinic with a blood pressure of 158/102 mmHg. She reports a frontal headache and right upper quadrant pain for the past 6 hours. On examination, she has brisk reflexes with 2 beats of clonus. Urine dipstick shows 2+ proteinuria. Her platelet count is 95,000/μL, serum creatinine is 1.2 mg/dL, and AST is 68 U/L. What is the most appropriate immediate next step in management?
A. Administer intramuscular betamethasone and arrange urgent delivery within 24 hours
B. Perform emergency cesarean section under general anesthesia immediately
C. Admit for expectant management with antihypertensive therapy and weekly monitoring
D. Start oral nifedipine and observe for 48 hours before deciding on delivery
Explanation
Clinical Diagnosis
This patient presents with severe preeclampsia with severe features at 34 weeks gestation:
Key Point
The clinical triad of severe hypertension (≥160/110 mmHg), severe headache with right upper quadrant pain, and thrombocytopenia (platelet count <100,000/μL) with elevated transaminases indicates HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) — a life-threatening variant of severe preeclampsia.

Rationale for Correct Answer
High-YieldNEET PG
At 34 weeks with HELLP syndrome, the standard of care is delivery within 24 hours after maternal stabilization with corticosteroids for fetal lung maturity.
Key Point
1.
Administer intramuscular betamethasone (12 mg × 2 doses, 24 hours apart) to accelerate fetal lung maturity and reduce neonatal morbidity/mortality — this is standard even at 34 weeks when delivery is imminent.
2.
Arrange urgent delivery within 24 hours — HELLP syndrome is an indication for delivery regardless of gestational age because maternal mortality risk escalates rapidly. Vaginal delivery is preferred if cervix is favorable; otherwise, cesarean section.
Clinical Pearl
The presence of 2 beats of clonus (ankle clonus) is a sign of severe CNS hyperreflexia and increased seizure risk — this mandates urgent delivery and seizure prophylaxis (magnesium sulfate).
Why NOT Expectant Management
Expectant management (option 1) is contraindicated in HELLP syndrome because:
Platelet count <100,000/μL indicates active hemolysis and thrombocytopenia.
Elevated transaminases signal hepatic injury.
Maternal mortality increases with each hour of delay.
Expectant management is reserved for preeclampsia without severe features at <34 weeks.
Why NOT Observation Alone
Oral nifedipine (option 3) alone is inadequate because:
It does not address the underlying HELLP pathology.
Observation for 48 hours risks maternal eclampsia, pulmonary edema, acute kidney injury, or placental abruption.
Delivery is the definitive treatment for HELLP syndrome.
Why NOT Immediate Cesarean Without Corticosteroids
Emergency cesarean (option 4) without prior corticosteroid administration is suboptimal because:
A 24-hour window allows one dose of betamethasone, which significantly reduces neonatal respiratory distress syndrome, intraventricular hemorrhage, and neonatal death.
If maternal condition deteriorates acutely (eclampsia, pulmonary edema, DIC), emergency cesarean is performed immediately, but the initial approach is stabilization + corticosteroids + planned delivery.
Seizure Prophylaxis
Key Point
Magnesium sulfate (loading dose 4–6 g IV over 20–30 minutes, then 1–2 g/hour infusion) must be started immediately for seizure prophylaxis in severe preeclampsia with severe features.
