A nurse is preparing to administer acetaminophen to a child weighing 7 lbs 3 oz. The provider orders Tylenol 12 mg/kg/dose PO every 6 hours as needed for pain. The pharmacy supplies acetaminophen 160 mg/5 mL. How many milliliters should the nurse administer per dose?

Identify the child's weight and convert to total ounces Weight: 7 lbs 3 oz Total Ounces = (7 lbs * 16 oz) + 3 oz Total Ounces = 112 + 3 = 115 oz Convert weight to kilograms (kg) Weight in lbs = 115 oz / 16 oz = 7.1875 lbs Weight in kg = 7.1875 lbs / 2.2 = 3.267 kg Calculate the dose in milligrams (mg) Ordered Dose: 12 mg/kg Total mg per dose = 3.267 kg * 12 mg/kg Total mg per dose = 39.204 mg Calculate the volume to administer in milliliters (mL) Available Concentration: 160 mg / 5 mL Volume = (Desired Dose / Available Dose) * Available Volume Volume = (39.204 mg / 160 mg) * 5 mL Volume = 0.245 * 5 = 1.225 mL Round the final answer Rounding to the nearest tenth = 1.2 mL
