Question 1 of 5
The nurse is caring for a 7-year-old child with burns covering the entire head and both legs. Using the provided chart, what is the calculated percentage of total body surface area involved?
Correct Answer: 69
Rationale: The correct answer is 69%.
To calculate total body surface area (TBS
A) involved in burns, we use the rule of nines chart. For a child, the head represents 18% of TBSA, each leg represents 14%, totaling 32%. Adding the head and legs, we get 50%. However, since the entire head and both legs are affected, we double the percentage to 100%.
Therefore, the calculated percentage of TBSA involved is 100% - 31% (the unaffected parts) = 69%. This percentage accounts for the areas with burns on the head and both legs. Other choices are incorrect as they do not consider the specific areas involved or miscalculate the TBSA.
