What stage of pressure sore occurs when the lesion extends into the dermis and subcutaneous fat begins to show?

The correct answer indicates the stage of a pressure sore where the lesion has progressed to the point of extending into the dermis and revealing subcutaneous fat. In the classification of pressure sores, this particular stage is characterized by full-thickness tissue loss. At this stage, not only has the epidermis and dermis been compromised, but the subcutaneous tissue is also exposed, indicating a more severe level of injury. Additionally, this stage may involve necrosis and damage to the surrounding tissue, which distinguishes it from earlier stages.

Understanding the progression of pressure sores is vital for effective management and treatment. Each stage reflects the severity of tissue damage, with stage 3 denoting significant impairment requiring prompt intervention to prevent further complications and promote healing.
