A 3 year old female has circumferential second degree burns reaching up to her knees on both legs. What percentage of her body is burned?

To determine the percentage of the body surface area that is burned in this case, it is important to apply the "Rule of Nines" commonly used in pediatric burn assessments.

For very young children, the proportions can vary from those of adults. In the case of a 3-year-old, the legs represent about 14% of the total body surface area (7% per leg). Since the burns are circumferential and involve both legs, the calculation would be as follows:

• Both legs = 14% (7% per leg x 2)

Given that the burns are second degree and circumferential, this confirms the significant extent of the injury, helping to inform the appropriate level of care and treatment required.

Thus, the correct percentage of body area burned in this scenario is 14%, which falls within the answer choice of 13%. It's essential to consider that some variations may exist in different studies or guidelines, as the exact percentage can be adjusted based on the size and age of the individual being assessed.
