A nurse is assessing a patient's wound and notes a shallow open area with a red-pink wound bed and no slough or bruising. The wound appears moist, and the surrounding skin is intact. Based on the accepted pressure injury staging system, how should the nurse categorize this finding?
- Unstageable, obscured full-thickness skin and tissue loss
- Stage 1, non-blanchable erythema with intact skin
- Stage 2, partial thickness skin loss with exposed dermis
- Stage 3, full-thickness skin loss with visible subcutaneous tissue
