A nurse is preparing to administer 000 mL of lactated Ringer's IV over 6 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 ["28"]
Calculate the total infusion time in minutes:
6 hours X 60 minutes/hour = 360 minutes
Calculate the total number of drops:
1000 mL X 10 gtt/mL = 10,000 gtt
Calculate the drip rate:
Drip rate (gtt/min) = Total drops / Total infusion time (minutes)
Drip rate = 10,000 gtt / 360 minutes = 27.78 gtt/min
Rounded to the nearest whole number, the drip rate is 28 gtt/min.

Correct Answer is ["125"]
Explanation
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 ["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
