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?

A. Physical activity stimulates bowel motility; avoiding exercise may worsen opioid-induced constipation. B. Increasing dietary fiber (fruits, vegetables, whole grains) promotes stool bulk and regular bowel movements, which helps counteract the slowed intestinal motility caused by opioid use. C. Adequate hydration (at least 2–3 L/day unless contraindicated) is necessary to soften stools; restricting fluids to 1 L/day can worsen constipation. D. Bulk-forming laxatives may cause bloating or obstruction if fluid intake is insufficient and are not routinely recommended without medical advice. Fiber and fluids should be tried first, with stool softeners or mild stimulants added if necessary.
