A nurse is teaching a client who has chronic pain about avoiding constipation from opioid medications. Which of the following information should the nurse include in the teaching?

A. While adequate fluid intake is important, 1.5 L per day might not be sufficient for a client with chronic pain and opioid use. The client should aim for a higher intake, as recommended by healthcare providers. B. Increasing physical activity helps promote bowel motility, reducing the risk of constipation. Regular exercise can help counteract opioid-induced constipation. C. Mineral oil should not be recommended due to its risk of aspiration and interference with vitamin absorption. D.
