AEMCA Practice Exam

According to the rule of nines, what percentage of an adult's palm is considered?

1. 0%

2. 1%

3. 5%

4. 9%

The correct answer is: 1%

The concept of using the palm of an adult's hand as a measurement tool for estimating total body surface area (TBSA) affected by burns is based on the rule of nines. According to this rule, the entire palm, including the fingers, is allocated a specific percentage of body surface area. In this framework, it is recognized that the palm represents approximately 1% of an adult's total body surface area. This is a practical method for quick assessments in emergency scenarios, especially when more comprehensive methods are not feasible. The other percentages noted in the options do not align with the established understanding of the rule of nines. This makes the choice of 1% the correct answer, effectively helping healthcare providers make faster, more accurate decisions when treating burn injuries.
