A nurse is collecting data from a client who has acute gastroenteritis. Which of the following data collection findings should the nurse identify as the priority?

Rationale: A. Urine specific gravity of 1.035 indicates concentrated urine and dehydration but is less immediately dangerous than severe hypokalemia. B. Weight loss of 3% is significant but less immediately life-threatening. C. Potassium of 2.5 mEq/L is severely low (normal 3.5–5.0 mEq/L) and can cause life-threatening cardiac dysrhythmias and muscle weakness, making it the priority. D. Blood glucose of 150 mg/dL is mildly elevated and less urgent
