Correct answer: DIntravenous magnesium sulphate

A seizure in a woman with pre-eclampsia is eclampsia, and intravenous magnesium sulphate is the specific treatment for controlling and preventing further seizures, alongside urgent transfer and blood pressure management. Benzodiazepines and phenytoin are less effective than magnesium in this setting and are not first-line. Lowering the blood pressure is important but is not itself the immediate anticonvulsant treatment. Pearl: magnesium also has a role in preventing eclampsia in severe pre-eclampsia, not solely in treating an established fit.
