Which option best explains the purpose of regular repositioning for immobile patients?

• A. Consistent hydration
• B. Regular turning and repositioning
• C. High-protein diet
• D. Limitations on movement

Answer: (B)

Regular repositioning is about preventing pressure injuries by relieving the constant load on vulnerable areas. When someone can’t move, the pressure from lying in one position compresses blood vessels in areas like the sacrum and heels, cutting off blood flow to the skin and underlying tissues. Turning and adjusting positions at set intervals relieves that pressure, redistributes it to new surfaces, and helps restore blood flow, which protects skin integrity and reduces the risk of ulcers. It also helps reduce friction and shear injuries and can improve comfort and circulation.

Hydration and good nutrition support overall healing but don’t directly prevent pressure injuries the way moving and shifting position does. Limiting movement would worsen risk, not prevent it.
