The healthcare provider prescribes digoxin elixir 125 mcg PO daily. The drug is available in a 60 mL bottle labeled, "Digoxin elixir 0.05 mg/mL." How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct answer
2.5
Rationale
First, convert the prescribed dose to the same units as the available concentration. 125 mcg = 0.125 mg. The available concentration is 0.05 mg/mL. The calculation is: (0.125 mg) / (0.05 mg/mL) = 2.5 mL.
