Which of the following is a known risk factor for pressure ulcer development?

Immobility is a well-established risk factor for the development of pressure ulcers. When a person is unable to change position on their own, the pressure exerted on specific areas of the skin increases. This prolonged pressure can restrict blood flow to the skin and underlying tissues, leading to tissue ischemia and ultimately causing skin breakdown. Individuals who are bedridden or use a wheelchair and cannot shift their weight are particularly vulnerable, as the constant pressure can lead to the formation of pressure ulcers over time.

In contrast, adequate hydration, regular repositioning, and a high protein diet are generally associated with better skin integrity. Adequate hydration helps maintain skin elasticity and resilience, while regular repositioning can relieve pressure on susceptible areas, reducing the risk of ulcer formation. A high protein diet supports overall tissue health and aids in the repair and regeneration of damaged skin. These factors contribute to reducing the likelihood of pressure ulcer development rather than increasing it.
