What consequence might occur from prolonged pressure on the skin?

Prolonged pressure on the skin can lead to the development of a pressure injury, also known as a pressure ulcer or bedsore. This occurs when blood flow to the skin is restricted, usually due to immobility or constant pressure against hard surfaces, preventing adequate oxygen and nutrient delivery to the tissues. Over time, this compromised circulation can result in tissue damage, which manifests as localized injury to the skin and possibly deeper tissues.

The skin may initially show signs of redness, but if the pressure is not relieved, it can evolve into more severe stages of injury, including blistering, open sores, and even skin and tissue necrosis. Preventive measures, such as regular repositioning and use of specialized cushions, are essential in avoiding these injuries in at-risk individuals, especially among those who are bedridden or have limited mobility.

The other options do not accurately describe the primary consequence of prolonged pressure on the skin. Tanning and callousing are responses more associated with environmental exposure or friction rather than sustained pressure, while pain can result from a pressure injury but is not a direct consequence of the prolonged pressure itself.
