To determine the total body surface area burned for a patient with full-thickness burns to the anterior torso and the anterior surface of both arms, we apply the Rule of Nines, which provides a method to estimate the total body surface area affected by burns.
1. Anterior Torso:
- The anterior (front) part of the torso accounts for [tex]\( 18\% \)[/tex] of the total body surface area.
2. Anterior Surface of Each Arm:
- Each arm is approximately [tex]\( 9\% \)[/tex] of the total body surface area when considering both the anterior and posterior surfaces together.
- Since we are only considering the anterior (front) part of each arm, this constitutes half of the arm's total burn area, which is [tex]\( 4.5\% \)[/tex] per arm.
3. Combining Both Arms:
- Since both arms are affected, we calculate the burn area for both anterior arm surfaces:
[tex]\[
4.5\% + 4.5\% = 9\%.
\][/tex]
4. Total Body Surface Area Burned:
- Adding the burn area of the anterior torso and the anterior surfaces of both arms, we get:
[tex]\[
18\% + 9\% = 27\%.
\][/tex]
Thus, the total body surface area burned for this patient is:
c. [tex]\( 27\% \)[/tex].
