What is a fourth degree burn?

An injury limited to the epidermis
An injury that extends to muscles and bones
An injury affecting only the dermis
A minor skin burn

The correct answer is: An injury that extends to muscles and bones

A fourth-degree burn is characterized by its severity, as it penetrates through the epidermis and dermis, extending into the underlying tissues, including muscles and bones. This type of burn results in significant damage and can severely affect the integrity of the skin and surrounding tissues, leading to complications that may require surgical intervention, such as skin grafting or even amputation. In the context of burn classifications, the levels range from first to fourth degree based on depth and damage. First-degree burns affect only the outer layer of skin (epidermis), causing redness and pain. Second-degree burns involve both the epidermis and part of the dermis, presenting with blisters and more intense pain. Third-degree burns extend deeper, affecting all layers of skin and potentially damaging nerves and tissues beneath. Fourth-degree burns represent the most extreme form of thermal injury, significantly impacting the body's structural integrity, and often resulting in permanent damage.
