Answer 4

Correct Answers:

Losartan 25 mg every 12 hr

Rationale :

🔶 Losartan is an angiotensin II receptor blocker and should be clarified in a postpartum client if breastfeeding status is unknown, because it can pose safety concerns during lactation.

🔶 The nurse should verify whether the client is breastfeeding, review maternal blood pressure needs, and confirm the safest antihypertensive choice with the provider.

🔶 Postpartum medication review requires special attention to drugs that may affect the newborn through breast milk.

🔶 The safest nursing action is to clarify the prescription before administration.
