The nurse is developing the plan of care and reviewing prescriptions. Choose the most likely options for the information missing from the statement by selecting from the list of options provided. The nurse knows that dropdownwill help decrease blood pressure, while dropdownwill help prevent seizures.

Rationale for correct choices Hydralazine: Hydralazine is a direct vasodilator commonly used in obstetric emergencies to rapidly reduce severe hypertension. It works by relaxing vascular smooth muscle, which decreases systemic vascular resistance and lowers blood pressure. In postpartum clients with suspected preeclampsia, rapid control of hypertension helps reduce the risk of stroke and other complications. Magnesium sulfate: Magnesium sulfate is the medication of choice for preventing seizures in clients with preeclampsia or postpartum preeclampsia. It depresses the central nervous system and reduces neuromuscular excitability, lowering the risk of eclamptic seizures. The client’s severe headache, visual disturbances, hyperreflexia, and right upper quadrant pain are classic warning signs of severe preeclampsia. Rationale for incorrect choices Oxytocin: Oxytocin is primarily used to stimulate uterine contractions during labor or to manage postpartum hemorrhage by promoting uterine tone. It does not have antihypertensive properties and does not reduce systemic blood pressure. In this scenario, the primary concern is severe hypertension associated with postpartum preeclampsia. Enalapril: Enalapril is an angiotensin-converting enzyme inhibitor used to treat hypertension in nonpregnant adults. Although sometimes used postpartum, it is not typically the first-line medication for rapid blood pressure control in acute obstetric emergencies. IV medications such as hydralazine or labetalol are preferred for immediate management. Lactated Ringer's: Lactated Ringer's solution is an isotonic IV fluid used for hydration and maintenance of fluid balance. It does not prevent seizures or treat the neurological complications associated with preeclampsia. While IV fluids may be administered to maintain vascular volume, they do not provide anticonvulsant protection. Calcium gluconate: Calcium gluconate is used as the antidote for magnesium sulfate toxicity rather than for seizure prevention. It is administered if a client receiving magnesium sulfate develops respiratory depression or loss of reflexes. In the absence of magnesium toxicity, calcium gluconate does not prevent seizures.
