A nurse is preparing to administer digoxin 8 mcg/kg/day PO to divide equally every 12 hr for a preschooler who weighs 33 lb. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
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

Explanation
Step-by-Step Calculation
Understanding the Problem
We need to administer 50 mL of ampicillin over 30 minutes.
We need to calculate the infusion rate in mL/hr.
Calculations
Convert minutes to hours:
30 minutes = 30/60 hours = 0.5 hours
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 50 mL / 0.5 hr = 100 mL/hr
The nurse should set the pump to deliver 100 mL/hr.
Correct Answer is ["0.8"]
Explanation
Desired dose = 30 mg
Available concentration = 40 mg/mL
To calculate the volume to administer, use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 30 mg / 40 mg/mL = 0.75 mL
Rounded to the nearest tenth, the nurse should administer 0.8 mL of enoxaparin.
