What should be done if someone has impaired mobility to prevent pressure sores?

Repositioning individuals with impaired mobility at least every two hours is essential to preventing pressure sores. When individuals remain in one position for extended periods, pressure can build up on certain areas of the body, particularly bony prominences such as heels, elbows, and the buttocks. This pressure can restrict blood flow to the skin, leading to skin breakdown and the development of pressure ulcers.

Regular repositioning helps alleviate pressure, promote blood circulation, and ensure that different areas of the skin are relieved from prolonged weight-bearing. It also allows for the inspection of skin integrity, enabling early detection of any signs of discomfort or potential ulcers.

The other options do not adequately address the needs of individuals with impaired mobility. Staying in the same position can exacerbate the risk of pressure sores, limiting movements may lead to further complications, and while a firm mattress might provide some support, it cannot replace the necessity of regular repositioning. Therefore, implementing a schedule for repositioning is the most effective strategy to prevent pressure sores.
