Which medication is used to prevent seizures in preeclampsia as described in Renee Workman's materials?

• A. Magnesium sulfate continuous IV infusion @ 2 g/hr
• B. Dinoprostone insert
• C. Restrict hourly fluids
• D. Ephedrine

Answer: (A)

Magnesium sulfate infusion is used to prevent seizures in preeclampsia. It calms neural activity and stabilizes membranes, which lowers the risk of progression to eclamptic seizures when given with proper monitoring. A loading dose is followed by a maintenance infusion around 2 g/hour to maintain therapeutic levels and protect against seizures while the condition is managed. Because magnesium has a narrow therapeutic window, clinicians monitor signs of toxicity—deep tendon reflexes, respiratory rate, urine output, and magnesium levels—and are prepared to administer calcium gluconate if toxicity occurs. The other options do not provide seizure prophylaxis in preeclampsia: dinoprostone is for cervical ripening and labor induction, restricting fluids is not a seizure-prevention strategy and can be unsafe, and ephedrine is used to treat hypotension, not to prevent seizures.
