Question: 1 / 400

What is the typical characteristic of a stage 4 pressure injury?

Intact skin with non-blanchable redness

Partial thickness skin loss

Full thickness tissue loss with exposed bone, tendon, or muscle

A stage 4 pressure injury is characterized by full thickness tissue loss, where the damage extends through the epidermis and dermis, reaching the underlying tissue and exposing structures such as bone, tendon, or muscle. This significant level of tissue damage signifies that the injury is severe and can often lead to complications like infection or osteomyelitis due to exposure of deeper structures.

This stage represents the most advanced level of pressure injury classification according to the National Pressure Injury Advisory Panel (NPIAP) guidelines. Understanding the implications of such injuries is crucial for effective wound care management and prevention strategies. Recognizing this critical distinction ensures that appropriate treatment plans are developed, focusing on the complexity and depth of the wound to promote healing and prevent further tissue damage.
