What is a key characteristic of a third degree burn?

• A. Skin remains intact
• B. Blisters form
• C. Skin and underlying tissue are burned through
• D. Only the outer layer of skin is affected

Answer: (C)

A key characteristic of a third degree burn is that it involves a complete destruction of the skin layers and underlying tissue. In this type of burn, the damage extends through the epidermis and dermis, leading to charring or a waxy white appearance of the affected area. This level of burn typically results in the loss of sensation in the area due to nerve damage, which distinguishes third degree burns from less severe burns.

Unlike burns that only affect the outer layer of skin, which may still retain some function and sensation, or those that cause blistering without penetrating deeper layers, a third degree burn indicates a severe injury requiring medical intervention and often surgical treatment such as skin grafts. Proper understanding of burn classifications is essential for providing appropriate care and assessing treatment needs for patients.
