A nurse is admitting a client to the postpartum unit and is reviewing the client's prescribed medications.

Choice A rationale: Losartan is an angiotensin II receptor blocker (ARB) and is generally contraindicated during breastfeeding due to potential risks to the infant's renal development and blood pressure. Choice B rationale: Ferrous fumarate is a standard iron supplement prescribed postpartum to treat or prevent anemia resulting from blood loss during delivery, making this a safe and expected prescription. Choice C rationale: Docusate sodium is a stool softener frequently used postpartum to prevent straining and alleviate constipation, especially if the client had an episiotomy, lacerations, or is taking iron. Choice D rationale: Prochlorperazine is an antiemetic used to manage nausea and vomiting. While it requires monitoring for sedation, it is a common PRN medication in the immediate postpartum period.
