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 ["675"]
Explanation
Convert pounds to kilograms: 198 lb ÷ 2.2 lb/kg = 90 kg
Calculate the total daily dose: 15 mg/kg/day X 90 kg = 1350 mg/day
Calculate the dose per administration: 1350 mg/day ÷ 2 doses = 675 mg/dose
Correct Answer is ["31"]
Explanation
Convert hours to minutes: 2 hours X 60 minutes/hour = 120 minutes
Calculate the total number of drops: 250 mL X 15 gtt/mL = 3750 gtt
Calculate the drip rate: 3750 gtt / 120 minutes = 31.25 gtt/min
Round to the nearest whole number: 31 gtt/min
