What is the primary intervention to prevent pressure ulcers in immobile patients?

• A. Increased fluid intake.
• B. Regular repositioning and pressure-relieving devices; skin care.
• C. Surgical intervention to relieve pressure.
• D. Routine massage to legs.

Answer: (B)

Preventing pressure ulcers in immobile patients hinges on relieving and redistributing pressure and protecting the skin. Regular repositioning reduces the duration of pressure on any one area, allowing blood flow to return and tissues to stay viable. Using pressure-relieving devices, such as specialized mattresses and cushions, further lowers the interface pressure at bony prominences. Good skin care supports the barrier function, keeps the skin dry, and helps prevent breakdown, especially where moisture exposure or friction exists. Together, these practices directly address the forces that cause ulcers and are the most effective preventive strategy. Increasing fluids alone, surgical intervention, or massage don’t tackle the ongoing pressure load in the way repositioning and protective surfaces do.
