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 ["50"]
Explanation
The provider has prescribed an IV infusion at a rate of 150 mL/hr. The drop factor of the manual IV tubing is 20 gtt/mL.
To find out how many gtt/min the IV flow rate should be set to, we can use the formula:
Flowrate(gtt/min) = Volume(mL/hr)×Dropfactor(gtt/mL) / 60min/hr
Substituting the given values:
Flowrate(gtt/min) = 150mL/hr×20gtt/mL=50gtt/min / 60min/hr
So, the nurse should set the IV flow rate to deliver 50 gtt/min.
Correct Answer is ["1.2"]
Explanation
Here's how to calculate the digoxin dosage:
1. Convert the child's weight to kilograms:
- There are approximately 2.2 pounds in 1 kilogram.
- 33 lbs / 2.2 lbs/kg = 15 kg
2. Calculate the total daily dose:
- The child needs 8 mcg of digoxin per kilogram of weight per day.
- 8 mcg/kg * 15 kg = 120 mcg
3. Calculate the dose per administration:
- The daily dose is divided into two doses (every 12 hours).
- 120 mcg / 2 = 60 mcg
4. Convert the dose per administration to milligrams:
- There are 1000 mcg in 1 mg.
- 60 mcg / 1000 mcg/mg = 0.06 mg
5. Calculate the volume to administer:
- The digoxin elixir has a concentration of 0.05 mg/mL.
- 0.06 mg / 0.05 mg/mL = 1.2 mL
