A child who weighs 18 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labelled, "Amoxicillin for Oral Suspension, USP 400 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.)

1.3 mL of amoxicillin suspension with each dose. To calculate the correct dose of amoxicillin to give to the child, follow these steps: Step 1: Convert the child's weight from pounds to kilograms. 18 pounds ÷ 2.2 = 8.18 kilograms Step 2: Calculate the total daily dose of amoxicillin. 25 mg/kg/day x 8.18 kg = 204.5 mg/day Step 3: Divide the total daily dose into two equal doses to be given every 12 hours. 204.5 mg/day ÷ 2 doses = 102.25 mg/dose Step 4: Determine how many mL of the suspension contain 102.25 mg of amoxicillin. 400 mg/5 mL = 80 mg/mL 102.25 mg ÷ 80 mg/mL = 1.28 mL
