The healthcare provider prescribes a loading dose of digoxin 0.6 mg intravenously (IV) for a client with heart failure (HF). The nurse obtains digoxin Injection 500 mcg in 2 mL vial from the electronic medication system. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.4"]
The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.
This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).
The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:
Volume in mL = 0.25 mg/mL 0.6 mg / 0.25 mg/mL = 2.4 mL
If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.

Explanation
The vial contains 500 mcg (or 0.5 mg) of digoxin in 2 mL.
This means that each mL contains 0.25 mg of the medication (0.5 mg / 2 mL = 0.25 mg/mL).
The nurse needs to administer 0.6 mg of the medication. To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 0.25mg/mL 0.6mg / 0.25mg/mL = 2.4mL
If rounding is required to the nearest tenth, the nurse should administer 2.4 mL of the medication.
Correct Answer is ["60"]
Explanation
Here's how to calculate the gentamicin dosage per dose for the child:
Client weight conversion:
Client weight: 66 lbs
We need the weight in kilograms (kg) for the medication dosage.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 66 lbs / 2.205 lbs/kg = 30 kg (round to nearest whole number)
Gentamicin dosage:
Prescribed dose: 2 mg/kg/dose (given)
Calculate the total gentamicin amount per dose:
Total dose (mg/dose) = Dose (mg/kg/dose) x Client weight (kg)
Total dose (mg/dose) = 2 mg/kg/dose * 30 kg
Total dose (mg/dose) = 60 mg (round to nearest whole number)
Therefore, the child should receive 60 mg of gentamicin sulfate per dose.
