A five year old child presents to the emergency department with burns. The burn area corresponding to the size of his palm is equal to
**Core Concept**
The rule of nines is a method used to estimate the size of burns in adults, but for children, the Lund-Browder chart or the "rule of palms" is employed. The "rule of palms" is a simplified method to estimate the size of burns in children, which states that the burn area corresponding to the size of one palm is approximately 1% of the body surface area (BSA).
**Why the Correct Answer is Right**
The "rule of palms" is a useful estimation tool for pediatric burns, as it takes into account the varying proportions of body surface areas in children. This rule is based on the fact that the palm area is roughly 1% of the total body surface area in children, making it a reliable and quick method for burn assessment. The Lund-Browder chart is more accurate but can be complex for quick estimations.
**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect, as there is no specific percentage of body surface area corresponding to the size of the child's face.
* **Option B:** Incorrect, as this option is not a valid estimation method for pediatric burns.
* **Option C:** Incorrect, as this percentage is not accurate for the size of the child's palm.
**Clinical Pearl / High-Yield Fact**
Remember that the Lund-Browder chart is a more accurate method for estimating burn size in children, but the "rule of palms" is a quicker and more practical tool for initial assessments.
**Correct Answer: C. 1%.**
