A nurse is preparing to administer digoxin 8 mg/kg/day PC divided equally every 12 hr for a preschooler who weighs 33 b. 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"]
Step-by-step solution:
1. Convert pounds to kilograms:
1 lb = 0.453592 kg
33 lb x 0.453592 kg/lb = 14.97 kg
2. Calculate the total daily dose of digoxin:
Total daily dose = dose per kg/day x weight in kg = 8 mcg/kg/day x 14.97 kg = 119.76 mcg/day
3. Calculate the dose per administration:
Since the medication is divided into 2 doses per day,
Dose per administration = Total daily dose / number of doses = 119.76 mcg/day / 2 doses = 59.88 mcg/dose
4. Convert mcg to mg:
1 mg = 1000 mcg
59.88 mcg = 0.05988 mg
5. Calculate the volume to administer:
The medication concentration is 0.05 mg/mL.
Volume = Dose per administration / Concentration = 0.05988 mg / 0.05 mg/mL = 1.1976 mL
6. Round to the nearest tenth:
Volume = 1.2 mL
Therefore, the nurse should administer 1.2 mL of digoxin per dose.

Correct Answer is ["84"]
Explanation
The nurse should administer 8.4 mg of enoxaparin per dose.
Calculations:
Convert pounds to kilograms:
185 lb x 0.453592 kg/lb = 83.91 kg
Calculate the enoxaparin dose:
1 mg/kg x 83.91 kg = 83.91 mg
Round to the nearest tenth:
83.91 mg ≈ 84 mg
Therefore, the nurse should administer 84 mg of enoxaparin per dose.
Correct Answer is ["8"]
Explanation
Understanding the problem
We need to administer 2g of nafcillin.
The reconstituted solution has a concentration of 250 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Convert grams to milligrams:
2 g = 2000 mg
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL
Calculate the volume:
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.
