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?

A. Famotidine is used for reducing gastric acid secretion and is not indicated for constipation. B. Loperamide is an antidiarrheal agent and would worsen constipation. C. Magnesium hydroxide is an osmotic laxative, but oral administration might cause cramping and is less appropriate when perineal healing is a concern. D. A rectal suppository of bisacodyl is effective in stimulating a bowel movement in postpartum clients with perineal lacerations, where straining should be minimized.
