A client receives a prescription for heparin sodium 20,000 Units in 5% dextrose injection 500 mL to be infused at a rate of 880 units/hour. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numeric value only.)
The Correct Answer is ["22"]
The client receives a prescription for heparin sodium 20,000 Units in 5% dextrose injection 500 mL to be infused at a rate of 880 units/hour.
The concentration of heparin in the IV solution is 40 units/mL (20,000 units / 500 mL).
Since the healthcare provider prescribes 880 units/hour of heparin, the nurse should program the infusion pump to deliver 22 mL/hour of the IV solution (880 units/hour / 40 units/mL).

Explanation
The child receives a prescription for asparaginase 4,780 IU IV.
The vial is labeled "Asparaginase 10,000 IU single-use vial" and for IV use, it should be reconstituted in 5 mL.
Since the child needs 4,780 IU of asparaginase and the vial contains 10,000 IU, the nurse should administer 2.39 mL of medication (4,780 IU / 10,000 IU * 5 mL).
Correct Answer is ["40"]
Explanation
A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour.
The IV tubing has a minidrip chamber that delivers 60 microdrops/mL.
To calculate the infusion rate in microdrops/minute, we need to multiply the infusion rate in mL/hour (40 mL/hour) by the number of microdrops/mL (60 microdrops/mL) and divide by the number of minutes in an hour (60 minutes/hour).
The nurse should regulate the microdrop gravity IV infusion to deliver 40 microdrops/minute (40 mL/hour * 60 microdrops/mL / 60 minutes/hour).
