A nurse is reviewing laboratory findings for a client who has acute kidney disease. Which of the following findings should the nurse expect?

A. Hemoglobin 19 g/dL: Acute kidney injury often leads to decreased erythropoietin production, which can cause anemia rather than elevated hemoglobin levels. A level of 19 g/dL is above normal and not expected in acute kidney disease. B. Serum creatinine 6 mg/dL: Elevated serum creatinine is a hallmark of acute kidney injury, reflecting impaired kidney filtration and accumulation of nitrogenous waste. A value of 6 mg/dL indicates significant kidney dysfunction and aligns with expected laboratory findings. C. Serum potassium 3.0 mEq/L: Acute kidney injury typically causes hyperkalemia due to decreased potassium excretion. A potassium level of 3.0 mEq/L is below normal and not expected in this condition. D. BUN 8 mg/dL: Blood urea nitrogen usually rises in acute kidney injury as a result of decreased renal clearance. A BUN of 8 mg/dL is within normal limits and does not reflect the impaired kidney function commonly seen in acute kidney disease.
