A nurse is preparing to administer acetaminophen 15 mg/kg PO to a preschool child for fever. The child weighs 30 lb. Available is acetaminophen liquid 160 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.)

Convert the child's weight from pounds to kilograms: Weight in pounds: 30 lb Conversion: 1 lb ≈ 0.454 kg Weight in kg: 30 lb× 0.454 kg/lb =13.62 kg 30lb×0.454kg/lb=13.62kg Calculate the dose in mg: Dose: 15 mg/kg 15 mg/kg ×13.62kg=204.3 mg Determine the volume to administer: Available concentration: 160 mg/5 mL Volume in mL: 204.3 mg ÷160 mg/5 mL = 204.3mg×5ml ÷160mg =6.4mL The nurse should administer 6.4 mL of acetaminophen.
