Question: 1 / 400

Which characteristic indicates a stage III pressure ulcer?

Partial thickness loss of skin

Full thickness skin loss

A stage III pressure ulcer is defined by full thickness skin loss, which distinguishes it from other stages. This means that there is a complete loss of skin, with the wound extending through the dermis and into the subcutaneous tissue. The key characteristic of a stage III ulcer is that it may present with visible adipose (fat) tissue but does not expose bone, tendon, or muscle.

The other options reference different aspects of skin and tissue damage. For instance, a pressure ulcer with partial thickness loss of skin indicates a stage I or II ulcer, not III. Similarly, exposed bone or tendon and damage to the underlying tissue typically characterize stage IV pressure ulcers, which indicate a more severe level of tissue destruction. Thus, identifying a pressure ulcer as stage III hinges on recognizing the nature of the full thickness involvement of skin and tissue without exposing underlying structures.
