A nurse is reviewing the labs on a client with 30% TBSA burns. What is the nurse's priority when interpreting the lab results?

A. Assessing white blood cell count: While important for monitoring infection, WBC changes are not the most immediate concern during the early phase of major burns. Infection risk becomes more critical later in the course. B. Assessing the electrolyte levels: Burns covering 30% TBSA cause massive fluid and electrolyte shifts, especially sodium and potassium imbalances. These changes can lead to cardiac arrhythmias, shock, and organ dysfunction, making this the top priority. C. Reviewing liver function tests: Liver function may be affected in severe burns, but this is not an early or primary concern. It is monitored more for metabolic function or drug metabolism later in treatment. D. Checking the red blood cell count: Hematocrit may rise initially due to hemoconcentration, but fluid and electrolyte disturbances have more immediate, life-threatening consequences in the acute phase.
