<prompt> Rapid infusion of insulin causesHyper kalemiaHypokalemiaHypernatremiaHyponatremia  <response>: B i.e. Hypokalemia Insulin promotes the transpo of K potassium and phosphate PO4 into cells leading to hypokalemia and hypophosphatemiaQ, i.e. L K . Effect of Insulin on K and PO43- - Insulin increases the transpo of potassium K from plasma into cells by stimulating the Na-K - ATPase pumps in cell membranes of muscle, liver and adipocytes. This results in lowering of plasma extracellular K concentration i.e. hypokalemiaQ. - Infusions of insulin and glucose significantly lower the plasma K levels in normal individuals and are used for temporaty relief of hyperkalemia in patients with renal failure, waiting for dialysis. - Hypokalemia often develops when patients with diabetic acidosis are treated with insulin. - Insulin induces rapid entery of glucose into cells, a process which is followed by phosphorylation reaction in glycolytic pathway, lowering the intracellular concentration of inorganic phosphate, and therefore promotes phosphate P03-4 entry into cells. This is how insulin 1t hypophosphatemia decrease plasma ECF PO43-
