A nurse is assessing a patient who has been immobile for several days following abdominal surgery. During the skin assessment, the nurse notes redness over the patient's sacrum that does not turn white when pressed with a finger. Which pressure injury stage does this finding most likely represent?
- Stage 3, because full-thickness skin loss has occurred
- Unstageable, because the wound base is covered with eschar
- Stage 2, because there is partial-thickness skin loss with exposed dermis
- Stage 1, because the dermis remains intact with non-blanchable erythema
