How often should a patient move positions to avoid pressure ulcers?

• A. Every 2 hours at least
• B. Every 4 hours
• C. Every 30 minutes
• D. Once daily

Answer: (A)

Regular repositioning relieves local pressure and restores tissue perfusion, which is essential to prevent pressure ulcers in patients with limited mobility. Moving the patient at least every two hours shifts pressure away from vulnerable areas (like heels, sacrum, and elbows) before ischemia and tissue damage can occur. Longer intervals allow prolonged compression and increase ulcer risk, so every four hours or less frequent is not as effective. Very frequent changes (e.g., every 30 minutes) may be used only in specific high-risk situations, but the standard minimum practice is every two hours.
