<prompt> Rapid infusion of insulin causes -HyperkalemiaHypokalemiaHypernatremiaHyponatremia  <response>: Ans. is b i.e., Hypokalemia Insulin causes K to enter cells with a resultant lowering of extracellular K concentration.Hypokalemia often develops when patients with diabetic acidosis are treated with insulinPotassium stores are depleted during diabetic ketoacidosis: -During tt with insulin and fluids various factors contribute to the development of Hypokalemia These include: -Insulin mediated potassium transport into cells.Resolution of the acidosis which also promotes potassium entry into cells.Urinary loss of potassium salts of organic acids.
