Hyperkalemia without ECG changes may be treated with all except :: (A) Calcium gluconate, (B) Salbutamol, (C) Na bicarbonate, (D) Insulin with dextrose
Answer is A. Calcium antagonizes the cardiac conduction abnormalities induced by potassium. In the given question, the patient has no ECG changes; therefore calcium gluconate will not be useful. Use of calcium gluconate should be restricted to life-threatening hyperkalemia.
