Question

Determine the TBSA % using the rule of 9's. Anterior head, circumferential (front & back) of left arm, anterior trunk, genitals, anterior portion of bilateral legs.

A) 35%
B) 40%
C) 45%
D) 50%

Answer 1

The TBSA % using the rule of 9's can be calculated by summing up the percentages associated with each burn area. The correct answer is D) 50%.

Step-by-step explanation:

The rule of 9's is used to estimate the percentage of total body surface area (TBSA) affected by burns. According to the rule, specific parts of the body are associated with a certain percentage of TBSA. For the given areas, the TBSA % can be calculated as follows:

1. Anterior head: 4.5%
2. Circumferential (front & back) of left arm: 9%
3. Anterior trunk: 18%
4. Genitals: 1%
5. Anterior portion of bilateral legs: 19.5%

To determine the total TBSA %, just sum up the percentages for each area: 4.5% + 9% + 18% + 1% + 19.5% = 52%. Therefore, the correct answer is D) 50%.
