What is the total percentage of skin that the thorax represents according to the Rule of Nines?

The Rule of Nines is a method used to estimate the total body surface area (TBSA) involved in burns. According to this system, the body is divided into sections that represent approximately 9% or multiples thereof of the total body surface area.

In adults, the thorax is divided into two main areas: the anterior chest (front) and the posterior chest (back). Each of these areas is considered to represent 18% of the total body surface area, combining to a total of 36% for the thorax region when considering both sides.

Understanding the breakdown of body areas in burn assessments is crucial, as accurate estimations can significantly affect treatment decisions and urgency in burn management. Hence, the correct answer reflecting the total percentage of skin that the thorax represents is 36%.
