What characterizes a severe burn injury according to RTC burn criteria?

A severe burn injury is characterized by full thickness burns affecting more than 2% of the body surface area. This definition stems from the established burn criteria used in the assessment and management of burn injuries. Full thickness burns, also known as third-degree burns, extend through all layers of the skin and can involve underlying tissues. They typically present with a charred appearance and lack sensation in the affected area due to nerve damage, representing a significant risk of complications and requiring extensive medical treatment.

In contrast, partial thickness burns, which affect a smaller percentage of body surface area or involve skin layers less severely, do not qualify as severe burns in this context. Minor chemical burns and superficial burns, which involve less damage and typically heal without significant intervention, also do not meet the criteria for severity. Therefore, option B reflects the criteria for recognizing a severe burn injury, emphasizing the implications for treatment and the potential for complications associated with such injuries.
