A client who weighs 22 pounds receives a prescription for amoxicillin 50 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled "Amoxicillin for Oral Suspension, USP 250 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.)

Calculation Steps: Step 1: Convert weight from pounds to kilograms: 22 pounds ÷ 2.2 = 10 kg. Result = 10 kg. Step 2: Calculate the total daily dose of amoxicillin: 50 mg/kg/day × 10 kg = 500 mg/day. Result = 500 mg/day. Step 3: Calculate the dose per administration: 500 mg/day ÷ 3 doses/day = 166.7 mg/dose. Result = 166.7 mg/dose. Step 4: Determine how many mL are needed for each dose: 250 mg/5 mL = 50 mg/mL, 166.7 mg ÷ 50 mg/mL = 3.3 mL. Result = 3.3 mL.
