A Stage 1 pressure ulcer is characterized by intact skin with nonblanchable redness. This means that the skin's surface remains unbroken but exhibits a persistent area of redness that does not fade when pressure is applied. This nonblanchable redness indicates that there is an underlying issue with blood flow and tissue perfusion, which is often linked to prolonged pressure on the skin.

Recognizing nonblanchable redness is crucial in preventing further skin breakdown, as it is typically the first sign of pressure-related injury. When identified early, interventions can be implemented to relieve pressure and maintain skin integrity, thereby preventing progression to more severe stages of pressure ulcers, which involve greater tissue damage and loss.

Other options refer to more advanced stages of pressure ulcers. For instance, partial thickness skin loss pertains to Stage 2 ulcers, while full thickness tissue loss and blister formation are indicators of further progression in the ulcer stages. Understanding this distinction is essential for effective skin assessment and appropriate nursing interventions.
