Which classification of pressure ulcers involves significant tissue damage through the dermis?

The classification of pressure ulcers is essential for determining the severity and appropriate treatment of skin injuries related to prolonged pressure. Stage 3 pressure ulcers are characterized by full-thickness tissue loss that extends through the dermis and into the subcutaneous tissue. At this stage, there may also be visible fat tissue, although muscle and bone are not exposed. This significant tissue damage indicates that the ulcer has progressed beyond the superficial layers, which is crucial for establishing a treatment plan and anticipating healing needs.

Stage 1 involves localized redness of intact skin without damage, while Stage 2 presents as a partial-thickness loss of skin involving the epidermis and possibly the dermis, but does not extend through deep tissues. Stage 4 involves extensive destruction with exposure of bone, muscle, or tendon, indicating a more severe condition that requires even more intensive care. Choosing Stage 3 correctly identifies that the ulcer has progressed to a point of significant tissue damage but has not yet reached the complete destruction characteristic of Stage 4.
