What is a key intervention to prevent pressure ulcers in bedridden patients?

• A. Reposition every 2 hours and use cushions or specialty mattresses
• B. Keep the patient in one position to avoid friction
• C. Massage bony prominences every hour
• D. Use a standard mattress without cushions

Answer: (A)

Prolonged pressure on the skin and underlying tissues, especially over bony prominences in a bedridden patient, can cut off blood flow and cause pressure ulcers. The most effective prevention combines relieving pressure regularly and supporting the body to spread out weight. Repositioning every two hours takes pressure off vulnerable areas, and cushions or specialty mattresses help distribute that pressure more evenly and reduce shear forces. This approach protects common hotspots like the sacrum and heels and promotes better tissue perfusion.

Keeping the patient in one position maintains the same pressure points and increases risk. Massaging bony prominences frequently isn’t a reliable or safe preventive practice and can damage tissue. A standard mattress without cushions doesn’t reduce pressure or protect the skin.
