A nurse in an emergency department is reviewing the medical record of a client who has an extensive burn injury. Which of the following laboratory results should the nurse expect?

Choice A reason: Hypokalemia, or low potassium levels, is not typically expected in clients with extensive burn injuries. In fact, during the acute phase of burn injury, hyperkalemia is more common due to the release of potassium from damaged cells and the impairment of kidney function.Choice B reason: Metabolic alkalosis is not a common finding in clients with extensive burns. Instead, metabolic acidosis is more likely due to the increased production of lactic acid from tissue hypoxia and impaired perfusion. Burn injuries can lead to significant fluid and electrolyte shifts, but metabolic alkalosis is not the usual result.Choice C reason: Low hemoglobin can occur in burn patients due to fluid shifts and the loss of red blood cells from the injury itself. However, it is not the most characteristic laboratory finding associated with extensive burns compared to hyperkalemia.Choice D reason: Hyperkalemia is the expected laboratory result in clients with extensive burn injuries. Burns cause massive cell destruction, leading to the release of intracellular potassium into the bloodstream. Additionally, impaired kidney function in the acute phase can further contribute to elevated potassium levels, making hyperkalemia a common and critical concern in burn patients.
