A nurse is teaching about preventing constipation to a client who has a new prescription for oxycodone. Which of the following statements by the client indicates an understanding of the teaching?

Rationale: A. "I will avoid strenuous exercise.": Physical activity, including regular moderate exercise like walking, actually helps stimulate bowel function. Avoiding exercise may worsen constipation rather than prevent it. B. "I will increase my intake of high-fiber foods.": A high-fiber diet supports regular bowel movements by increasing stool bulk and promoting peristalsis. This is a key strategy for preventing opioid-induced constipation. C. "I will take a bulk-forming laxative every day.": Bulk-forming laxatives can be helpful, but daily use should be discussed with a provider, as they can worsen constipation if fluid intake is insufficient. Dietary changes are usually the first recommended step. D. "I will limit my fluid intake to 1 liter per day.": Limiting fluid intake can lead to dehydration and hard stools, worsening constipation. Adequate hydration is essential to help fiber work effectively and support regular bowel function.
