What is the rationale for repositioning immobile patients every 1 to 2 hours?

• A. To prevent pressure ulcers and skin breakdown.
• B. To improve sleep quality.
• C. To reduce weight gain.
• D. To shorten bath times.

Answer: (A)

Regularly repositioning immobile patients every 1 to 2 hours prevents pressure ulcers by relieving sustained pressure on skin and underlying tissues, which preserves blood flow and tissue viability. When someone cannot move, prolonged pressure over bony areas such as the heels, sacrum, and hips compresses capillaries, causing ischemia and potential tissue breakdown. Turning redistributes the load to new areas, reduces friction and shear, and allows skin to recover, especially when moisture from incontinence or sweating is present. While repositioning can improve comfort and sleep, its primary purpose in immobile patients is to protect skin integrity and prevent ulcers. The other options—improving sleep quality, reducing weight gain, or shortening bath times—do not address this risk to skin and tissue.
