What contributes to the development of pressure sores?

1. Frequent movement

2. Good hydration

3. Dependence on others for mobility needs

4. Regular repositioning

The correct answer is: Dependence on others for mobility needs

The development of pressure sores, also known as pressure ulcers, is primarily associated with prolonged pressure on certain areas of the skin, especially in individuals who have limited mobility. When a person is dependent on others for mobility, they may be less able to reposition themselves and relieve pressure on at-risk areas of the body, such as the heels, sacrum, and elbows. This lack of movement can impede blood flow and result in tissue ischemia, ultimately leading to skin damage and the formation of pressure sores. In contrast, frequent movement, good hydration, and regular repositioning are all protective factors against the development of pressure sores. Frequent movement helps redistribute pressure, while good hydration supports skin integrity and overall health. Similarly, regular repositioning can significantly reduce the risk by alleviating pressure points, making the reliance on others for mobility needs a key contributor to the development of pressure sores.
