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 take a bulk-forming laxative every day.": While bulk-forming laxatives can help manage constipation, taking them without adequate fluid intake can worsen constipation or cause bowel obstruction. Education should emphasize combining fiber with sufficient fluids. B. "I will avoid strenuous exercise.": Regular physical activity actually promotes intestinal motility and helps prevent opioid-induced constipation. Avoiding exercise would counteract this preventive strategy. C. "I will increase my intake of high-fiber foods.": Consuming high-fiber foods, such as fruits, vegetables, and whole grains, adds bulk to stool and promotes regular bowel movements. This is a key dietary intervention for preventing constipation in clients taking opioids like oxycodone. D. "I will limit my fluid intake to 1 liter per day.": Limiting fluids can exacerbate constipation because hydration is necessary to soften stool and support normal bowel function. Clients should maintain adequate fluid intake alongside increased dietary fiber.
