How often should immobile patients be repositioned to prevent pressure ulcers?

• A. Every 4 hours
• B. Every 6 hours
• C. Only when skin integrity is noted to be at risk
• D. About every 2 hours, per facility protocol

Answer: (D)

Regular repositioning is essential to prevent pressure ulcers by relieving continuous pressure on bony areas and reducing shear that can damage tissue. For immobile patients, rotating positions about every two hours helps restore blood flow to vulnerable areas, especially over the sacrum, heels, and hips, before tissue viability is compromised. Following facility protocol acknowledges that the exact schedule can vary, but two-hour intervals are the standard preventive practice. Repositioning only when skin shows risk or signs of breakdown is reactive rather than preventive, and waiting too long between turns (every four or six hours) increases the chance of ulcer development.
