What is the standard intravenous infusion protocol for regular insulin in managing diabetic ketoacidosis?
Answer and explanation
Correct answer: D. Continuous infusion of 0.1 units per kilogram per hour
Answer: Continuous infusion of 0.1 units per kilogram per hour.
Why not the others: Boluses of 1 unit/kg cause catastrophic rapid drops in blood glucose and cerebral edema; Subcutaneous glargine provides erratic absorption during acute hypoperfusion and cannot be rapidly titrated; 5 units/kg/h is an enormous overdose that precipitates fatal hypoglycemia and hypokalemia.
