A nurse is teaching a client about managing opioid-induced constipation. Which statement by the client indicates a correct understanding of the role of dietary fiber?

Increasing fiber intake alone is sufficient to prevent opioid-induced constipation without considering fluid intake.

Most dairy products are good sources of dietary fiber and should be increased.

Fiber decreases peristalsis, which helps prevent diarrhea caused by opioids.

Fiber absorbs water in the intestines, creating softer and bulkier stool that is easier to pass.
