A nurse is caring for a client who is 12 hr postpartum and has a third-degree perineal laceration. The client reports not having a bowel movement for 4 days. Which of the following medications should the nurse administer?

The correct answer is A: Bisacodyl 10 mg per rectum. Bisacodyl is a stimulant laxative that helps stimulate bowel movements. Given the client's situation of not having a bowel movement for 4 days postpartum with a third-degree perineal laceration, prompt relief is needed to prevent complications such as constipation or increased pressure on the perineal area. Administering Bisacodyl per rectum will provide a faster onset of action compared to oral medications, ensuring timely relief for the client.

Choice B: Magnesium hydroxide is a laxative used for constipation but may not provide immediate relief for the client in this urgent situation.

Choice C: Famotidine is a histamine-2 blocker used for managing stomach acid but is not indicated for addressing constipation.

Choice D: Loperamide is an antidiarrheal medication and is contraindicated in this scenario as it can worsen constipation.
