Which of the following is a major risk factor for pressure ulcers?

Immobility is a major risk factor for pressure ulcers because when an individual is unable to move or change positions frequently, it leads to prolonged pressure on specific areas of the skin. This sustained pressure can impede blood flow to the underlying tissues, resulting in tissue ischemia and ultimately skin breakdown. Those who are bedridden, in wheelchairs, or have limited mobility are particularly vulnerable, as the lack of movement reduces the body’s natural ability to relieve pressure from bony prominences.

On the other hand, increased hydration helps maintain skin integrity and support overall health, making it a protective factor against pressure ulcers. A high protein diet is beneficial for wound healing and skin health, while frequent repositioning is a preventative measure that helps reduce the risk of developing pressure ulcers by ensuring that pressure is distributed across different areas of the body rather than sustained in one location. Thus, immobility stands out as the key risk factor that can lead to the development of pressure ulcers.
