<prompt> A girl presented with severe hyperkalemia and peaked T waves on ECG. Fastest way of shifting potassium intracellularly is-Calcium gluconate IVOral resinsInsulin glucoseSodium bicarbonate  <response>: reference : Emergency management of acute hyperkalemia Medication Response type Onset of action Duration of action Mechanism of action Expected decrease in potassium level Calcium gluconate rapid 1-2 min 30-60 min Protect cardiomyocytes 0.5-1.5 mEqL Glucose insulin intermediate 10-20min 2-6 hours Shift potassium intracellularly 0.5-1.5 mEqL dose dependent Beta-agonists intermediate 3-5min 1-4 hours Shift potassium intracellularly Sodium bicarbonate only in patients with metabolic acidosis, bicarbonate 22mEqL intermediate 30-60min 2-6 hours Shift potassium intracellularly questionable effect Exchange resin delayed 2-6hours 4-6 hours Elimination of potassium from the body Furosemide delayed 5-30 min 2-6 hours Elimination of potassium from the body Hemodialysis delayed immediate Elimination of potassium from the body 1mmolL in the first 60 min and total of 2mmoll by 180 min
