What is the recommended frequency to reposition immobile patients to prevent pressure ulcers?

• A. Every 4 hours.
• B. Only when uncomfortable.
• C. Every 1 hour.
• D. Every 2 hours.

Answer: (D)

Relieving continuous pressure on vulnerable areas is essential to prevent pressure ulcers. Repositioning shifts weight, restores blood flow, and reduces tissue ischemia for immobile patients. A practical and widely taught frequency is every 2 hours, which provides regular relief before tissue tolerance is exceeded while remaining feasible in typical care settings. If a patient has very high risk, incontinence with moisture, or uses devices that increase pressure, more frequent turning or additional preventive measures may be needed, but the baseline standard is every 2 hours. Always couple turning with good skin care, proper body alignment, and techniques that minimize shear and friction.
