A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 44 pounds. 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.)

To calculate the dosage of acetaminophen for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 44 pounds, which is equivalent to 20 kilograms (44 ÷ 2.2). The prescribed dose is 10 mg/kg, so the child's dose is 200 mg (20 kg × 10 mg/kg). Since the available medication is 120 mg/5 mL, divide the child's dose by the concentration to find the volume: 200 mg ÷ (120 mg/5 mL) = 8.33, which rounds to 8.3 mL.
