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 ["1.5"]
Explanation
Desired dose = 7.5 mg
Available concentration = 5 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 7.5 mg / 5 mg/mL
= 1.5 mL
Correct Answer is ["1"]
Explanation
Desired dose = 2 mg
Available concentration after reconstitution = 2 mg/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 2 mg / 2 mg/mL
= 1 mL
