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.)
The Correct Answer is ["8"]
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

Correct Answer is ["125"]
Explanation
Total volume to be infused = 250 mL
Infusion time in hours = 2 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
= 250 mL / 2 hours
= 125 mL/hour
Correct Answer is ["2.4"]
Explanation
Desired dose = 4,780 IU
Determine the available concentration for IV use after reconstitution:
Available concentration = 10,000 IU / 5 mL
= 2,000 IU/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (IU) / Available concentration (IU/mL)
= 4,780 IU / 2,000 IU/mL
= 2.39 mL
Round to the nearest tenth:
Rounded volume = 2.4 mL
