Which stage of pressure ulcer involves visible subcutaneous tissue?

In the classification of pressure ulcers, the correct answer refers to Stage 3, where there is a significant level of tissue damage. In this stage, the ulcer creates a deep wound that extends through the epidermis and dermis, reaching into the subcutaneous tissue. This visible exposure of subcutaneous fat is a hallmark sign of this stage, indicating that the injury has progressed beyond the initial layers of skin.

Stage 3 ulcers may also present with slough or necrotic tissue that can vary in amount, but the key feature is the presence of subcutaneous tissue. This stage underscores the importance of timely intervention to promote healing and prevent further deterioration. Understanding the specific characteristics of each stage of pressure ulcers is vital for effective assessment and management in clinical settings.
