What percentage of a child's body surface area does the back represent according to the Rule of 9's?

The correct answer is: 18%

In pediatric patients, the Rule of 9's is adapted to more accurately estimate the body surface area (BSA) in children, as their proportions differ from adults. According to this rule, the back of a child accounts for 18% of their total body surface area. This is part of a breakdown that simplifies the assessment of burn injuries by dividing the body into regions that collectively add up to 100%. Understanding this percentage is crucial for effective burn management, as it helps EMTs and other healthcare providers determine the severity of burns and the necessary treatment protocols. For example, knowing that 18% of the BSA corresponds to burns on the back enables first responders to promptly assess whether a patient requires advanced care or immediate intervention.
