How often should a patient be repositioned to prevent pressure injuries, and what aids can be used?

• A. Every 2 hours; wedges or pillows
• B. Every 4 hours; blankets
• C. Every 6 hours; foam mattress topper
• D. Every 2 hours; towels

Answer: (A)

Regularly repositioning a patient every two hours helps relieve pressure on bony prominences like the sacrum, heels, elbows, and hips, which is essential to prevent pressure injuries in immobilized individuals. Using supportive aids such as wedges or pillows keeps the body properly aligned and offloads pressure from these areas, distributing weight more evenly and reducing friction and shear. The two-hour schedule is more protective than longer intervals, since tissue can begin to divert blood flow and sustain damage with sustained pressure. While a foam mattress topper can improve comfort and some pressure distribution, it doesn’t substitute for the regular turning schedule or provide the targeted offloading that wedges and pillows offer. Blankets or towels aren’t reliable pressure-relief devices and can shift, bunch, or cause rubbing.
