Magnesium sulfate is used to prevent seizures in pregnancy-induced hypertension.

• A. True
• B. False
• C. Not enough information
• D. Only in certain patients

Answer: (A)

Magnesium sulfate serves as seizure prophylaxis in pregnancy-related hypertensive disorders by dampening neural excitability and stabilizing neuronal membranes, which helps prevent progression to eclampsia. It isn’t used to lower blood pressure itself; its role is specifically to protect the brain from seizures in women with preeclampsia, especially those with severe features or high seizure risk. In practice, it’s given intravenously with careful monitoring of reflexes, breathing, and urine output, and calcium gluconate is available as the antidote for toxicity. Because of this established use to prevent seizures in preeclampsia/eclampsia, the statement is true.
