Identify the stage of pressure ulcer that involves full thickness skin loss.

1. Stage I

2. Stage II

3. Stage III

4. Stage IV

The correct answer is: Stage III

The correct answer pertains to Stage III pressure ulcers, which are characterized by full thickness skin loss. In this stage, there is involvement of the epidermis and dermis, extending into the subcutaneous tissue. This means that the ulcer is deep enough to expose adipose (fat) tissue. Management of Stage III pressure ulcers requires careful wound care, and the areas around the ulcer may show signs of infection or necrosis due to the depth of the tissue damage. This stage indicates a significant loss of tissue integrity, which is crucial for understanding treatment approaches and the overall prognosis for healing. In the context of the other stages, Stage I involves non-blanchable erythema of intact skin; Stage II presents as partial thickness skin loss involving the epidermis and possibly part of the dermis, leading to a distinct wound; and Stage IV extends beyond the subcutaneous layer into muscle, bone, or supporting structures, indicating even greater severity. This distinction is important for healthcare providers as it influences management strategies and the urgency of interventions.
