An advanced practice registered nurse (APRN) is staging a pressure injury. The APRN notes partial-thickness skin loss involving the epidermis and dermis. How should the APRN document the stage of this pressure injury?

Pressure injuries are classified based on the depth and extent of tissue damage resulting from prolonged pressure, usually over bony prominences. Accurate staging is essential for guiding wound management, documenting severity, and predicting healing outcomes. Stage 2 pressure injuries involve partial-thickness skin loss extending through the epidermis and into the dermis, often presenting as an open shallow ulcer or blister. Correct identification ensures appropriate treatment and prevention of further tissue damage. Rationale: A. Stage 1 pressure injury involves intact skin with non-blanchable erythema over a localized area. There is no open wound or loss of skin layers, only changes in skin color and temperature. Since this case involves partial-thickness skin loss, it is more advanced than Stage 1. B. Stage 2 pressure injury is correctly documented because it involves partial-thickness loss of skin affecting the epidermis and dermis. It may present as an open shallow ulcer or an intact or ruptured serum-filled blister. The wound is superficial and does not extend into deeper tissues such as subcutaneous fat or muscle. C. Stage 3 pressure injuries involve full-thickness skin loss extending into the subcutaneous tissue, often with visible fat but not exposing bone, tendon, or muscle. The damage is deeper than Stage 2 and may include tunneling or undermining. Since this case is limited to epidermis and dermis, Stage 3 is too advanced. D. Stage 4 pressure injuries involve full-thickness tissue loss with exposed bone, tendon, or muscle. These are severe wounds with extensive destruction and high risk of complications such as osteomyelitis. The findings described do not indicate this level of tissue involvement, making Stage 4 incorrect.
