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).

Convert the child's weight from pounds (lb) to kilograms (kg) Given weight = 28 lb Conversion factor: 1 kg = 2.2 lb Weight (kg) = 28 lb / 2.2 lb/kg = 12.727 kg Calculate the Single Dose in milligrams (mg) Prescribed dose = 10 mg/kg/dose Single Dose (mg) = Weight (kg) x Dose (mg/kg/dose) = 12.727 kg x 10 mg/kg = 127.272 mg Calculate the Volume (mL) to Administer (Dose/Have Method) Ordered Dose (D) = 127.272... mg Available Dose (H) = 120 mg Quantity (Q) = 5 mL Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q) = (127.272 mg / 120 mg) x 5 mL = 1.0606 x 5 mL = 5.303 mL Round to the Nearest Tenth = 5.3
