Which of these can identify progression from preeclampsia to eclampsia?

• A. Active seizures
• B. Proteinuria
• C. Thrombocytopenia
• D. Rise in diastolic blood pressure

Answer: (A)

Recognizing progression to eclampsia is about identifying the onset of convulsive seizures in a patient with preeclampsia. The defining event that converts preeclampsia into eclampsia is a seizure, so active seizures directly indicate that progression has occurred. The other signs—proteinuria, thrombocytopenia, and a rise in diastolic blood pressure—are features of preeclampsia and can indicate severity, but they do not by themselves signify that seizures have started. Seizures mark the transition to eclampsia and require immediate emergency management.
