A provider prescribes dextrose 5% in water IV to infuse at 100 mL/hr. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number.)
The Correct Answer is ["100"]
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 B
Explanation
A) 1600: If the nurse were to administer the next bag at 1600, it would imply that the current solution would need to last only 2 more hours. However, with 500 mL remaining and a total infusion time of 8 hours, this timing would not align with the need to complete the full infusion period appropriately.
B) 1800: Since the IV solution is meant to be infused over 8 hours and 500 mL (half of the total 1,000 mL) has been infused by 1400, the remaining 500 mL should also be infused over the next 4 hours. Infusing the next bag at 1800 would ensure that the entire 8-hour infusion time is met correctly.
C) 1700: Administering the next bag at 1700 would mean that there would be only 3 hours left to infuse the remaining solution. This timing would not allow for a complete 8-hour infusion period as required.
D) 1500: If the nurse were to administer the next bag at 1500, it would be too early, as only 2 hours would have passed since starting the current bag. This would not be appropriate given the need to infuse the solution over the full 8-hour period.
Correct Answer is ["4"]
Explanation
Desired dose = 40 mg
Available concentration = 10 mg/mL
To calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 40 mg / 10 mg/mL = 4 mL
