A dose calls for 7 mcg/kg; the patient weighs 62.1 kg. What is the correct dose?

• A. 434.7 mg
• B. 3.447 mg
• C. 434.7 mcg
• D. 0.4347 mg

Answer: (C)

The main idea is to multiply the dose per kilogram by the patient’s weight to get the total dose, keeping track of units. 7 mcg/kg × 62.1 kg = 434.7 mcg. So the correct total dose is 434.7 micrograms. If you prefer milligrams, that’s 434.7 mcg ÷ 1000 = 0.4347 mg. Expressing the dose in micrograms is common for small-dose meds, but both units are equivalent when converted properly.
