A nurse is caring for client who has sepsis and a prescription for vancomycin 1 g in 250 mL dextrose 5% (DSW) over 2 hr by IV intermittent bolus. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["125"]
Understanding the Problem
We need to administer 250 mL of solution over 2 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Convert hours to minutes (optional, but can help visualize):
2 hours = 2 X 60 minutes = 120 minutes
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 250 mL / 2 hr = 125 mL/hr
Answer
The nurse should set the IV pump to deliver 125 mL/hr.

Correct Answer is ["28"]
Explanation
Calculate the total infusion time in minutes:
6 hours X 60 minutes/hour = 360 minutes
Calculate the total number of drops:
1000 mL X 10 gtt/mL = 10,000 gtt
Calculate the drip rate:
Drip rate (gtt/min) = Total drops / Total infusion time (minutes)
Drip rate = 10,000 gtt / 360 minutes = 27.78 gtt/min
Rounded to the nearest whole number, the drip rate is 28 gtt/min.
Correct Answer is ["217"]
Explanation
Total volume to be infused = 5200 mL
Total infusion time = 24 hours
Infusion rate for the entire 24 hours = 5200 mL / 24 hours = 216.67 mL/hr
Round to the nearest whole number for the first 8 hours: 217 mL/hr
