A nurse is caring for an older adult client who reports taking bisacodyl tablets daily. Which of the following responses should the nurse make?

Choice A reason: Excessive use of stimulant laxatives like bisacodyl can lead to significant electrolyte imbalances, particularly hypokalemia. Chronic stimulation of the bowel can impair natural peristalsis and disrupt fluid and electrolyte absorption. This is especially concerning in older adults who may already be at risk for dehydration and cardiac arrhythmias. Choice B reason: Advising a client to decrease intake of high-fiber foods is inappropriate. Fiber promotes regular bowel movements and supports intestinal health. Reducing fiber could worsen constipation and increase reliance on laxatives, which is counterproductive. Choice C reason: Irregular bowel movements can occur for various reasons, including diet, hydration, activity level, and medications. While they may signal a need for evaluation, they are not inherently indicative of poor intestinal health. This statement lacks specificity and may cause unnecessary concern. Choice D reason: While chronic laxative use can lead to complications such as dependence and mucosal irritation, a tear in the rectal mucosa is not a common or direct consequence of bisacodyl use. This statement is alarmist and not supported by typical clinical outcomes associated with stimulant laxatives.
