Calculation
A client who weighs 176 pounds is admitted to the intensive care unit with a serum glucose level of 600 mg/dL (33.3 mmol/L). Regular insulin at a rate of 0.1 unit/kg/hour is prescribed. The pharmacy provides a solution of regular insulin 100 units/100 mL of normal saline. The nurse should set the infusion pump to deliver how many mL/hours? (Enter numeric value only.)
mL/hour
Explanation & Rationale
Step 1: Convert the client's weight from pounds to kilograms. 176 pounds ÷ 2.2 = 80 kg Step 2: Determine the total units of insulin needed per hour. 80 kg × 0.1 unit/kg/hour = 8 units/hour Step 3: Determine the volume of insulin solution needed per hour. (8 units) ÷ (100 units/100 mL) = (8 units) ÷ (1 unit/mL) = 8 mL/hour So, the nurse should set the infusion pump to deliver 8 mL/hour.
