Wound Treatment Associate (WTA) Practice Exam

Which description best fits a deep tissue pressure injury?

1. Visible slough and granulation tissue

2. Persistent deep red or purple discoloration of intact skin

3. Full thickness loss with exposed underlying structures

4. Presence of eschar that covers the wound

The correct answer is: Persistent deep red or purple discoloration of intact skin

A deep tissue pressure injury is characterized primarily by a persistent deep red or purple discoloration of intact skin. This type of injury represents a significant level of tissue damage that may not be immediately apparent. The discoloration indicates underlying damage to the soft tissue, which can result from prolonged pressure or shear forces. Although the skin may appear intact, the deeper layers are compromised, reflecting potential injury to blood vessels and fibrous tissue. This nuanced distinction is critical when evaluating pressure injuries, as it emphasizes the importance of recognizing early signs of tissue damage to prevent progression to more severe injury types. In contrast, the other descriptions refer to different stages or types of pressure injuries, such as visible slough or granulation tissue, full thickness loss with exposed structures, and the presence of eschar, which are not consistent with the definition of a deep tissue pressure injury. Understanding these classifications helps in appropriate assessment and treatment planning.
