Calculation
A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb. The amount available is acetaminophen 120 mg/5 mL. 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
mL
Explanation & Rationale
Convert weight to kilograms: 28 lb ÷ 2.2 = 12.73 kg (approx. 12.7 kg) Calculate dose: 12.7 kg × 10 mg/kg = 127 mg Determine volume: 120 mg / 5 mL = 24 mg/mL 127 mg ÷ 24 mg/mL = 5.29 mL Rounded to nearest tenth: 5.3 mL
