The nurse is caring for a patient in the emergent/resuscitative phase of a burn injury. Upon analysis of the patient's laboratory studies, the nurse will expect the results to indicate:
A) Hyperkalemia, hyponatremia, elevated hematocrit, and metabolic acidosis
B) Hypokalemia, hypernatremia, decreased hematocrit, and metabolic acidosis
C) Hyperkalemia, hypernatremia, decreased hematocrit, and metabolic alkalosis
D) Hypokalemia, hyponatremia, elevated hematocrit, and metabolic alkalosis
Ans: A
Feedback: Fluid and electrolyte changes in the emergent/resuscitative phase of a burn injury include hyperkalemia related to the release of potassium into the extracellular fluid, hyponatremia from the large amount of sodium lost in trapped edema fluid, hemoconcentration that leads to an increased hematocrit, and loss of bicarbonate ions that results in metabolic acidosis.
