A client with pneumonia is receiving a secondary infusion of azithromycin 500 mg in 250 mL of normal saline (NS) to be infused in 90 minutes. How many mL/hour should the nurse program the infusion pump?
The Correct Answer is ["167"]
The client with pneumonia is receiving a secondary infusion of azithromycin 500 mg in 250 mL of normal saline (NS) to be infused in 90 minutes.
To calculate the infusion rate in mL/hour, we need to divide the total volume of the infusion (250 mL) by the infusion time in hours (90 minutes / 60 minutes/hour = 1.5 hours).
The nurse should program the infusion pump to deliver 167 mL/hour (250 mL / 1.5 hours).

Correct Answer is ["20"]
Explanation
The client is currently receiving an infusion labeled as 5% Dextrose Injection 500 mL with heparin sodium 25,000 Units. The concentration of heparin in the IV solution is 50 units/mL (25,000 units / 500 mL).
A prescription is received to change the rate of the infusion to heparin 1,000 units/hour.
Since the concentration of heparin in the IV solution is 50 units/mL, the nurse should program the infusion pump to deliver 20 mL/hour of the IV solution (1,000 units/hour / 50 units/mL).
Correct Answer is ["1.0"]
Explanation
-
Calculate the total dose:
- The client weighs 59 kg and the dose is 5 mcg/kg, so the total dose is 59 kg * 5 mcg/kg = 295 mcg.
-
Calculate the volume to administer:
- The medication is available at a concentration of 300 mcg/mL.
- To find the volume, divide the total dose by the concentration: 295 mcg / 300 mcg/mL = 0.9833 mL.
