A child who weighs 16 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 200 mg per 5 mL.”. How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Step 1 is to convert the child's weight from pounds to kilograms. 16 pounds ÷ 2.2 = 7.3 kg. Step 2 is to calculate the total daily dose in mg. 25 mg/kg × 7.3 kg = 182.5 mg. Step 3 is to determine the dose per administration, divided by 2 since the dose is given every 12 hours. 182.5 mg ÷ 2 = 91.25 mg. Step 4 is to convert the dose from mg to mL using the concentration of the medication. 91.25 mg ÷ (200 mg/5 mL) = 91.25 ÷ 40 = 2.3 mL per dose. The answer is 2.3 mL.
