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 D
Explanation
A) 32 units: This calculation only includes the 14 units of regular insulin and a portion of the NPH insulin. The total units of insulin required are not 32 but rather the sum of both regular and NPH insulins.
B) 28 units: This amount represents only the units of NPH insulin and does not include the regular insulin, which is also prescribed.
C) 14 units: This amount represents only the units of regular insulin and does not include the NPH insulin, which is also prescribed.
D) 42 units: The total number of insulin units required is the sum of the regular insulin (14 units) and the NPH insulin (28 units), which equals 42 units. This total should be prepared in the insulin syringe to ensure the correct dosage is administered.
Correct Answer is ["63"]
Explanation
Calculate total drops: 250 mL X 15 gtt/mL = 3750 gtt
Convert minutes to hours: 60 minutes = 1 hour
Calculate drip rate: 3750 gtt / 1 hour = 3750 gtt/hr
Convert to gtt/min: 3750 gtt/hr / 60 min/hr = 62.5 gtt/min
Round to nearest whole number: 63 gtt/min
