Which of the following represents the burn percentage for the anterior and posterior of both arms using the Rule of Nines?

A.

9%

B.

12%

C.

36%

D.

18%

Answer and Explanation

The Correct Answer is D

A. 9% represents the total surface area of one arm (anterior and posterior combined), not both arms.
B. 12% is not a correct calculation based on the Rule of Nines.
C. 36% represents a much larger area, such as the entire trunk (anterior and posterior), not just the arms.
D. According to the Rule of Nines, each arm accounts for 9% of total body surface area (4.5% anterior + 4.5% posterior). Therefore, both arms (anterior and posterior) equal 18% total

Explanation

B. The rule helps estimate the percentage of body surface area (BSA) burned, not calculate total BSA.
C. The rule of nines is a quick method to estimate the percentage of total body surface area affected by burns in adults. Each major section of the body is assigned a value that is a multiple of nine, aiding in fluid resuscitation and treatment planning.
