If an adult victim has various percentages of burns on their body, what total percent is burned if one-quarter of the back, all of the arms, and half of the head is burned?

To determine the total percentage of burns on the adult victim's body, it is important to apply the "Rule of Nines," which is commonly used in assessing burn areas in adults.

First, let's break down the percentage of burns for each area mentioned:

• One-quarter of the back: The entire back represents 18% of the body. Therefore, one-quarter of this area burned is calculated as follows: 18% / 4 = 4.5%.

• All of the arms: Both arms together account for 18% of the body (9% for each arm). Since both arms are fully burned, this adds: 18%.

• Half of the head: The entire head represents 9% of the body. Thus, half of the head that is burned equates to: 9% / 2 = 4.5%.

Now, add up the percentages from these areas: 4.5% (back) + 18% (arms) + 4.5% (half of head) = 27%.

The correct computation illustrates that the total percentage of burns on the victim's body is 27%. This value aligns with option B, confirming that it is the total amount burned
