A nurse is caring for a client who has preeclampsia and is experiencing a postpartum hemorrhage. The nurse should expect the provider to prescribe which of the following medications?

A. Methylergonovine: While effective for postpartum hemorrhage, it causes vasoconstriction and can raise blood pressure significantly. It is contraindicated in clients with preeclampsia or hypertension due to the risk of stroke or hypertensive crisis. B. Carboprost: Carboprost is used to treat postpartum hemorrhage, but it may increase blood pressure and is used cautiously in clients with preeclampsia. It is not typically the first-line treatment in hypertensive patients. C. Nifedipine: Nifedipine is a calcium channel blocker used for managing hypertension and preterm labor, not for controlling postpartum bleeding. It does not cause uterine contraction and is not effective for hemorrhage. D. Oxytocin: Oxytocin stimulates uterine contractions and is the first-line medication for managing postpartum hemorrhage. It does not raise blood pressure, making it safe and effective for clients with preeclampsia.
