A child weighing 20 kg would receive what Amoxicillin dose?

• A. 1 g
• B. 2 g
• C. 1.5 g
• D. 2.5 g

Answer: (A)

Dosing in children is based on milligrams per kilogram of body weight per day. To tailor the dose, you multiply the child’s weight by the recommended mg/kg/day to get the total daily amount, then divide by the number of doses per day if you need per-dose amounts. For amoxicillin, a common daily dose in many pediatric guidelines is about 50 mg per kg per day. So for a child weighing 20 kg, the total daily dose would be 20 × 50 mg = 1000 mg, which is 1 g per day. The exact per-dose amounts would depend on how many doses you give per day (for example, twice daily would be about 0.5 g per dose). The other options imply higher total daily amounts (e.g., 2 g, 1.5 g, or 2.5 g), which would correspond to higher mg/kg/day than typically used in standard regimens.
