Which nursing intervention is crucial for patients at risk for pressure ulcers?

Encouraging mobility and repositioning is a vital nursing intervention for patients at risk for pressure ulcers because these actions help to alleviate prolonged pressure on specific areas of the skin that can lead to ulcer formation. When a person remains in one position for too long, especially those with reduced mobility or sensation, blood flow to the skin and underlying tissues can become compromised, leading to ischemia and tissue necrosis. By promoting regular movement and changing positions, the pressure on vulnerable areas of the body—such as the heels, sacrum, and elbows—is reduced, thereby enhancing blood circulation and preventing skin breakdown.

This intervention is complemented by other practices, such as using special pressure-relieving mattresses or cushions, but the primary action of encouraging mobility and frequent repositioning is fundamental in the prevention of pressure ulcers.
