A nurse is performing a skin assessment on an immobile client and observes an area on the sacrum. The skin is intact, but there is a localized, nonblanchable area of erythema. Upon palpation, the nurse notes the area feels firmer and is slightly warmer than the surrounding skin. There is no purple or maroon discoloration. How should the nurse correctly stage this pressure injury?
