The healthcare provider prescribes regular insulin 8 units/hour IV. The IV solution contains "100 units of regular insulin in 100 mL of 0.9% normal saline." How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.)

Determine the concentration of the insulin solution: Concentration = Total units of insulin / Total volume of solution (mL) = 100 units / 100 mL = 1 unit/mL Calculate the infusion rate in mL/hour: Infusion rate (mL/hour) = Prescribed dose (units/hour) / Concentration (units/mL) = 8 units/hour / 1 unit/mL = 8 mL/hour
