The Correct Answer is ["8ml\/hour"]
The healthcare provider prescribes regular insulin 8 units/hour intravenously (IV).
The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline, so the concentration of insulin in the IV solution is 1 unit/mL (100 units / 100 mL).
Since the healthcare provider prescribes 8 units/hour of insulin, the nurse should program the infusion pump to deliver 8 mL/hour of the IV solution (8 units/hour / 1 unit/

Correct Answer is ["75ml\/hour"]
Explanation
The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour.
Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL).
Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).
Correct Answer is ["4 ml"]
Explanation
The client is receiving a prescription for penicillin 1.2 million units IM.
The available vial is labeled "600,000 units/2 mL", so the concentration of penicillin in the solution is 300,000 units/mL (600,000 units / 2 mL).
Since the healthcare provider prescribes 1.2 million units of penicillin, the nurse should administer 4 mL of medication (1.2 million units / 300,000 units/mL).
