What defines an unstageable pressure injury?

• A. Partial-thickness tissue loss with exposed dermis.
• B. Full-thickness tissue loss in which the wound bed is obscured by slough or eschar; depth cannot be determined until necrotic tissue is removed and assessed.
• C. Stage 3.
• D. Stage 4.

Answer: (B)

Unstageable injuries are defined by a full-thickness loss where you cannot see how deep the wound goes because the wound bed is hidden beneath necrotic tissue such as slough or eschar. Because that tissue covers the wound base, you can’t accurately assign a stage until the necrotic tissue is removed and the true depth is revealed. If the necrotic tissue is removed and the depth can be assessed, the wound may then be reclassified to the appropriate stage (ranging from the deeper tissue loss seen in higher stages to less extensive loss). This distinction helps explain why a wound that is clearly full-thickness isn’t staged until the covering tissue is evaluated. Partial-thickness losses involve only the outer layers and are not covered by necrotic tissue, which is why they’re not unstageable. Similarly, deeper stages require visible structures and a clear wound bed to determine the exact depth.
