A nurse is preparing to administer digoxin 0.15 mg PO. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3 "]
Given:
- Desired dose of digoxin: 0.15 mg
- Available strength of digoxin elixir: 0.05 mg/mL
First, find out how many milliliters of digoxin elixir correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 0.15 mg / 0.05 mg/mL Volume (mL) = 3 mL
So, the nurse should administer 3 mL of digoxin elixir.

Correct Answer is ["100 "]
Explanation
Given:
- Insulin glargine concentration: 100 units/mL
- Total volume of insulin in the vial: 10 mL
- Dose of insulin glargine per day: 10 units
Calculation:
First, let's find out how many total units are in the vial:
Total units = Concentration (units/mL) × Volume (mL) Total units = 100 units/mL × 10 mL
Total units = 1000 units
Now, let's find out how many doses can be obtained from the total units in the vial: Number of doses = Total units / Dose per day
Number of doses = 1000 units / 10 units/day Number of doses = 100 doses
So, the vial contains approximately 100 doses of insulin glargine.

A. Dose/strength - The prescription should specify the amount or concentration of the medication to be applied.
B. Time/frequency - The prescription already includes the time/frequency: "twice a day."
