Which nonpharmacologic measure is appropriate to prevent constipation in immobilized patients?

• A. Strict bed rest and reduced fluids
• B. High-dose stimulant laxatives without assessment
• C. Adequate fluid intake and activity as tolerated
• D. Avoiding fiber

Answer: (C)

Maintaining hydration and encouraging movement are key ways to prevent constipation in patients who are immobilized. Adequate fluid intake keeps stool soft and easier to pass, while activity as tolerated stimulates bowel movements through the gastrocolic reflex and improves overall gut motility. Together, these nonpharmacologic steps address the factors that slow the bowel when activity is limited.

The other approaches misalign with this goal. Strict bed rest with reduced fluids would worsen constipation by decreasing stool hydration and gut motility. Relying on high-dose stimulant laxatives without assessment is a pharmacologic strategy and can lead to dependency or adverse effects. Avoiding fiber misses a beneficial step, since adding dietary fiber (with sufficient fluids) promotes bulk and regularity; it should be increased gradually and tailored to the individual.
