A nurse implements a nursing care plan for a patient experiencing constipation. Which intervention should the nurse include in the plan?

A. Bed rest: Immobility contributes to constipation by slowing peristalsis. Early ambulation is preferred. B. Administering aluminum hydroxide antacids: Aluminum-based antacids can cause or worsen constipation. C. Increasing fiber in the diet: Fiber adds bulk to stool and promotes regular bowel movements. This is an effective non-pharmacological intervention. D. Restricting fluids: Dehydration worsens constipation. Adequate fluid intake is essential for softening stool and promoting bowel regularity.
