A nurse is preparing to administer digoxin 7.5 mcg/kg/day PO daily to a school-age child who weighs 52 lb. Available is digoxin elixir 50 mcg/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 ["3.5"]
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.5 mL per dose. The answer is rounded to the nearest tenth as instructed.

Correct Answer is ["0.65"]
Explanation
Let’s calculate this step by step:
Step 1: Convert the toddler’s weight from pounds (lb) to kilograms (kg) using the conversion factor 1 kg = 2.2 lbs.
24 lbs ÷ 2.2 lbs/kg = 10.91 kg
Step 2: Calculate the total amount of diazepam needed using the dosage of 0.3 mg/kg.
0.3 mg/kg × 10.91 kg = 3.27 mg
Step 3: Calculate the volume of diazepam injection to administer using the concentration of 5 mg/mL.
3.27 mg ÷ 5 mg/mL = 0.654 mL
Rounding to the nearest hundredth, the nurse should administer 0.65 mL of diazepam injection.
Correct Answer is ["133"]
Explanation
To calculate this, divide the volume of the infusion by the infusion time to find the rate: 800 mL / 6 hr =
133.33 mL/hr, which rounds to 133 mL/hr when rounded to the nearest whole number.
