A prescribed dose is 0.6 mg/kg. If the patient weighs 28 kg, what is the calculated dose?

• A. 16.8 mg
• B. 10.8 mg
• C. 8.4 mg
• D. 42 mg

Answer: (A)

Dosing by weight means you multiply the prescribed amount per kilogram by the patient’s weight in kilograms to get the total dose in milligrams. Here, 0.6 mg/kg multiplied by 28 kg equals 16.8 mg. So the patient should receive 16.8 mg. The other numbers don’t match the weight-based calculation; they would result from using different weights or a decimal error.
