A primary care provider writes a prescription for 0.15 milligram of digoxin intravenously every day. The medication is available in a concentration of 400 micrograms per mL. How many mL will the nurse administer? Round off to one decimal point.
Explanation
Medication calculations require careful unit conversion and an exact volume calculation so the correct dose is given. Convert all quantities to the same units, then divide the desired dose by the concentration to get the volume to administer.
Rationale for correct answer:
- Prescribed dose = 0.15 mg.
- Convert to micrograms (since available strength is in µg/mL):
0.15 mg × 1000 = 150 micrograms (µg). - Concentration available = 400 µg/mL.
- Volume = dose ÷ concentration = 150 µg ÷ 400 µg/mL = 0.375 mL.
Correct answer: 0.4 ml
Take home points
- Always convert units to match (mg → µg) before calculating volume.
- Draw the exact calculated volume when possible; if rounding is required, follow facility policy and document/verify.
