A patient received deep partial-thickness burns to the anterior trunk, perineum, and left posterior and anterior arm. Using the "Rule of nines," what is the percent of total body surface area (TBSA) that was burned?
18%
36%
40%
28%
The Correct Answer is D
Adding these percentages together:
- Anterior trunk: 18%
- Perineum: 1%
- Left anterior arm: 4.5%
- Left posterior arm: 4.5%
Total = 18% + 1% + 4.5% + 4.5% = 28%

Correct Answer is D
Explanation
Choice A rationale: individuals with extensive burn wounds are highly likely to develop metabolic acidosis and not metabolic alkalosis due to the increased risk of tissue hypoxia, increased lactic acid levels, and renal failure.
Choice B rationale: low hemoglobin is not an expected finding in individuals with extensive burn wounds but instead increased hemoglobin levels are expected due to hemoconcentration resulting from excessive fluid loss.
Choice C rationale: A patient with extensive burn wounds is expected to have hypovolemia and not hypervolemia due to increased fluid loss from the burned tissues and increased capillary permeability.
Choice D rationale: hyperkalemia is a common finding in individuals with extensive burn wounds due to massive cell destruction which releases potassium from the intracellular compartment to the extracellular compartment.
Correct Answer is ["0.8"]
Explanation
The amount to be administered = desired dose/ dose at hand X quantity of the solution
= 100/250 x 2
