A 5 year old has burns on the surface of his body corresponding to the size of his palm. The percentage of burns is?

## **Core Concept**
The question assesses the understanding of the "rule of nines" and the Lund-Browder chart, which are used to estimate the percentage of body surface area (BSA) affected by burns. In children, the proportion of body surface area changes with age, and the Lund-Browder chart is particularly useful.

## **Why the Correct Answer is Right**
The correct answer, , utilizes the Lund-Browder chart or a simplified version for children, which estimates that the palm of the patient's hand corresponds to about 1% of the body surface area. This rule of thumb is especially useful in emergency situations for quick estimation. Therefore, if the burns correspond to the size of the child's palm, it would be approximately 1% of the BSA.

## **Why Each Wrong Option is Incorrect**
- **Option A:** . This option suggests a much larger percentage than what would be estimated by the palm size rule.
- **Option B:** . Similarly, this is also larger than the estimated 1% for the palm size.
- **Option D:** . This option is smaller than the correct estimate.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that in pediatric patients, the "palm" rule (1% BSA per palm) is a quick and useful method to estimate burn area. This is especially helpful in the field or during the initial assessment.

## **Correct Answer:** .
