    Calculation

    A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

    mL

    Explanation & Rationale

    Rationale: Step 1: Convert weight from pounds to kilograms: 33 lb ÷ 2.2 ≈ 15 kg Step 2: Calculate total daily dose: 30 mg/kg/day × 15 kg = 450 mg/day Step 3: Divide for every 12 hr (2 doses/day): 450 ÷ 2 = 225 mg per dose Step 4: Determine mL per dose using available concentration: 200 mg : 5 mL = 225 mg : X mL Cross multiply: 200 × X = 225 × 5 200X = 1125 X = 1125 ÷ 200 = 5.625 ≈ 5.6 mL Final Answer: 5.6 mL
