For a patient who has burn injuries to the anterior of her face, neck, and torso, what is the burn size percentage?

When assessing burn injuries using the "Rule of Nines," which is commonly employed for estimating the total body surface area (TBSA) affected by burns, various body regions are assigned specific percentages. In adults, the anterior surface of the head and neck accounts for 9%, the anterior torso constitutes another 18%, and the anterior aspect of each arm contributes 4.5% respectively.

For a patient with burns to the anterior of the face, neck, and torso, we would calculate the total burn size as follows:

• Anterior face and neck = 9%
• Anterior torso = 18%

Adding these together provides a burn size of 27% TBSA.

This method of estimation is critical in managing burn patients, as it helps determine the severity of the burns and informs treatment decisions. The chosen answer accurately reflects the calculated percentages based on the "Rule of Nines," which is frequently taught in medical training, particularly in emergency and trauma care.
