What constitutes a severe burn in a 35-year-old patient?

• A. Partial-thickness burn to 20% of the body surface area.
• B. Full-thickness burn to 5% of the body surface area.
• C. Circumferential partial-thickness burn to the chest.
• D. Superficial burn covering 50% of the body surface area.

Answer: (C)

A circumferential partial-thickness burn to the chest is classified as a severe burn due to the potential for significant complications that can arise from this type of injury. A circumferential burn wraps around the body and can compromise circulation, cause pressure on the chest, and limit respiratory function by constricting the thoracic cavity. This is particularly dangerous because it may lead to respiratory distress or failure and necessitate immediate medical intervention such as escharotomy. In contrast, while a partial-thickness burn over 20% of the body surface area typically constitutes a major burn, it is not as immediately life-threatening or functionally compromising as a circumferential burn. A full-thickness burn covering 5% of the body is also serious but may not demonstrate the same immediate risk to vital functions, particularly if it is not circumferential. Superficial burns, regardless of their extent (in this case, covering 50% of the body), tend to be less severe in nature and usually heal without extensive medical treatment. Thus, the unique risks associated with a circumferential partial-thickness burn to the chest make it the best answer for what constitutes a severe burn in this scenario.
