A nurse is preparing to administer dextrose 5% in water (DSW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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 ["8"]
Convert hours to minutes: 3 hours X 60 minutes/hour = 180 minutes
Calculate the total number of drops: 150 mL X 10 gtt/mL = 1500 gtt
Calculate the drip rate: 1500 gtt / 180 minutes = 8.33 gtt/min
Round to the nearest whole number: 8 gtt/min

Correct Answer is ["100"]
Explanation
1. Understand the given information:
- Prescribed infusion rate: 100 mL/hr
- Drop factor: 60 gtt/mL
2. Convert the infusion time to minutes:
- 1 hour = 60 minutes
3. Calculate the drip rate (gtt/min):
- (Total volume (mL) × Drop factor (gtt/mL)) / Time (minutes) = gtt/min
- (100 mL × 60 gtt/mL) / 60 minutes = 100 gtt/min
4. Round to the nearest whole number:
- The answer is already a whole number.
Therefore, the nurse should set the IV flow rate to deliver 100 gtt/min.
Correct Answer is ["13"]
Explanation
Calculations
Calculate the total minutes:
24 hours = 24 X 60 minutes = 1440 minutes
Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Total volume (mL) / Total time (min)
Infusion rate = 1200 mL / 1440 min = 0.8333 mL/min
Calculate the drip rate:
Drip rate (gtt/min) = Infusion rate (mL/min) X Drop factor (gtt/mL)
Drip rate = 0.8333 mL/min X 15 gtt/mL = 12.5 gtt/min
The nurse should set the manual IV infusion to deliver 13 gtt/min.
