What characterizes a Stage 1 pressure ulcer?

A Stage 1 pressure ulcer is characterized by non-blanchable erythema of intact skin. This means that the affected area appears red and does not turn white when pressed (non-blanchable). The skin remains intact and there is no loss of tissue at this stage. This condition reflects potential damage to the underlying tissues, indicating that there is an increased risk for further skin breakdown. It is crucial for healthcare providers to recognize this early sign so that interventions can be implemented to prevent progression to more serious stages of pressure ulcers. In contrast, the other options describe more advanced stages of skin injury where there is either tissue loss or damage that has already occurred.
