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.

Correct Answer is ["83"]
Explanation
The nurse should set the infusion pump to deliver the entire 2 liters (2000 mL) over the course of 24 hours.
Therefore, the IV pump should be set to deliver:
Rate(mL/hr) = Totalvolume(mL) / Time(hr) = 2000mL / 24hr
After performing the calculation, we find that the rate equals 83.33 mL/hr.
So, the nurse should set the infusion pump to deliver 83 mL/hr (rounded to the nearest whole number).
This is because 83 mL of the solution contains the prescribed dose of penicillin G every hour.
Correct Answer is ["0.5"]
Explanation
here's how to calculate the volume (mL) of epinephrine the nurse should administer:
1. Client weight conversion:
Client weight: 110 pounds
Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 110 pounds / 2.205 lbs/kg
Client weight (kg) = 50 kg (round to nearest whole number)
2. Epinephrine dosage:
Prescribed dose: 0.01 mg/kg (given)
3. Epinephrine concentration:
The medication is labeled 1 mg/mL. This indicates there are 1 mg of epinephrine per 1 mL of solution.
4. We need to find the volume (mL) containing the prescribed dose (based on weight) of epinephrine (0.01 mg/kg) considering the concentration (1 mg/mL) in the vial.
Total epinephrine dose (mg): Dose (mg/kg) x Client weight (kg)
Total epinephrine dose (mg): 0.01 mg/kg * 50 kg
Total epinephrine dose (mg): 0.5 mg (round to nearest tenth)
Volume to administer (mL): Total dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 0.5 mg / 1 mg/mL
Volume to administer (mL): 0.5 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.5 mL of epinephrine intramuscularly.
