A nurse has a prescription for Bisacodyl (Dulcolax). For which condition is the nurse administering this medication?

Choice A rationale Bisacodyl (Dulcolax) is a stimulant laxative that acts by irritating the colon mucosa, increasing peristalsis, and promoting fluid accumulation in the colon to facilitate a bowel movement. Therefore, it is used to treat constipation, not diarrhea. Diarrhea management often involves antidiarrheal agents like loperamide or fluid replacement. Choice B rationale Bisacodyl is correctly prescribed for the management of constipation, which is characterized by infrequent bowel movements, difficulty passing stools, or hard stools. As a stimulant laxative, it works directly on the nerve plexuses in the bowel wall to enhance colonic motility, typically producing a bowel movement within 6 to 12 hours after oral administration. Choice C rationale Bisacodyl is used to relieve the symptom of constipation, and while abdominal discomfort can be a part of constipation, the medication is not a primary treatment for generalized abdominal pain of unknown etiology. Furthermore, excessive use or high doses of bisacodyl can sometimes cause or worsen abdominal cramping. Choice D rationale Fecal incontinence is the involuntary passage of stool, which can result from various conditions such as nerve damage or sphincter dysfunction. Bisacodyl, a laxative, would exacerbate fecal incontinence by promoting a bowel movement, making this an inappropriate and potentially harmful indication for its use.
