A client is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["250"]
- Calculate the infusion rate using the formula: mL/hour = (mL of solution) / (hours to infuse)
- Plug in the given values: mL/hour = (500 mL) / (2 hours)
- Simplify the expression: mL/hour = 250 mL
- The nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS

Correct Answer is ["42"]
Explanation
- Calculate the total volume in mL: 1 liter = 1000 mL
- Calculate the total infusion time in minutes: 8 hours x 60 minutes = 480 minutes
- Calculate the infusion rate in mL/min: 1000 mL / 480 minutes = 2.08 mL/min
- Calculate the infusion rate in gtt/min: 2.08 mL/min x 20 gtt/mL = 41.6 gtt/min
- Round to the nearest whole number: 42 gtt/min
Correct Answer is ["10.2"]
Explanation
- Calculate the dose of dopamine in mcg/min: 3 mcg/kg/min x 91 kg = 273 mcg/min
- Convert the dose to mg/hr: 273 mcg/min x 60 min/hr x 1 mg/1000 mcg = 16.38 mg/hr
- Calculate the infusion rate in mL/hr: 16.38 mg/hr x 250 mL/400 mg = 10.24 mL/hr
- Round to the nearest tenth: 10.2 mL/hr
- Program the infusion pump to deliver 10.2 mL/hr
