This is the only definitive cure for preeclampsia, eclampsia, and HELLP syndrome.

• A. Magnesium sulfate therapy
• B. Delivery of the placenta
• C. Antihypertensive therapy
• D. Bed rest

Answer: (B)

Preeclampsia, eclampsia, and HELLP syndrome arise from dysfunction of the placenta and its release of factors that cause widespread maternal endothelial injury, leading to high blood pressure, protein in the urine, and potential organ involvement. The decisive intervention is delivery of the placenta, which removes the source of those harmful factors and allows the mother's condition to improve and usually resolve afterward. Medications like magnesium sulfate are used to prevent or treat seizures and to protect the mother during this dangerous time, and antihypertensive therapy helps control blood pressure, but neither eliminates the placental pathology. Bed rest does not address the root cause and isn’t a cure. Once the placenta is delivered, symptoms typically begin to improve, making delivery the definitive treatment.
