Which of the following describes a Stage 2 pressure ulcer?

A Stage 2 pressure ulcer is characterized by partial thickness skin loss, which affects the epidermis and may extend into the dermis. This type of ulcer can present as an open sore with a red or pink wound bed, without slough (dead tissue). The distinguishing factor of a Stage 2 ulcer is that it involves the loss of the top layer of skin, which differentiates it from deeper stages that involve full thickness loss of tissue.

In contrast, other options describe features related to different stages of pressure ulcers. Full thickness tissue loss is indicative of Stage 3 or Stage 4 ulcers, where the damage extends through the dermis and may involve underlying tissues. Nonblanchable skin indicates a Stage 1 ulcer, where there is redness that does not fade when pressed, signifying danger for skin damage without actual skin loss. Cavity or tunneling is associated with advanced stages (primarily Stage 3 and Stage 4), where the ulcer extends into deeper tissues, forming pathways under the skin. Thus, identifying the correct description of Stage 2 is critical for proper assessment and treatment.
