Name a key risk factor for developing pressure ulcers in post-operative patients.

Immobility is a significant risk factor for developing pressure ulcers in post-operative patients. When individuals are unable to move or change positions frequently, it leads to prolonged pressure on specific areas of the skin. This sustained pressure reduces blood flow to the affected tissues, causing ischemia and potentially resulting in skin breakdown. In the post-operative environment, many patients may be confined to bed, limiting their mobility due to pain, sedation, or the nature of their surgical procedure. This immobilization necessitates diligent assessment and preventive measures to minimize the risk of pressure ulcer formation.

Other factors, while relevant, may contribute to pressure ulcer risk in different ways or to a lesser extent. For example, obesity can increase pressure due to additional body weight, dehydration can affect skin integrity, and skin infections can compromise the healing process; however, the primary driver of pressure ulcers remains the lack of movement and the resulting pressure on specific skin areas. Therefore, addressing immobility is crucial in post-operative care to prevent these complications.
