What medication should a nurse administer to a postpartum client with a third-degree perineal laceration who hasn't had a bowel movement for 4 days?

In the case of a postpartum client with a third-degree perineal laceration who hasn't had a bowel movement for four days, a rectal suppository such as bisacodyl is a suitable choice. This medication is a stimulant laxative that works by directly stimulating the intestinal mucosa and promoting bowel movements, making it effective for addressing constipation.

After childbirth, patients may experience delayed bowel movements due to factors such as pain from lacerations, fear of straining, or reduced mobility. In this scenario, the client is at an increased risk of constipation due to the laceration, which may make normal bowel movements uncomfortable or painful.

Selecting a rectal route can be advantageous in postpartum situations where abdominal pressure may be a concern, especially for those with perineal trauma. Bisacodyl can provide relatively quick relief, typically within 15 to 60 minutes, which is often necessary for postpartum clients who may be experiencing discomfort or distress due to prolonged constipation.

Other options, like magnesium hydroxide, senna tablets, or docusate sodium, while they have their uses, might not provide the timely or effective relief needed in this specific circumstance, especially considering the client's condition and the urgency of achieving a bowel movement.
