A nurse is preparing to administer amoxicillin 80 mg/kg/day to divide equally every 8 hr to a preschooler who weighs 33 lb. Available is amoxicillin oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

 Convert the child's weight from pounds to kilograms: 33 lb / 2.2 = 15 kg  Calculate the total daily dose of amoxicillin: 80 mg/kg/day 15 kg = 1200 mg/day  Divide the total daily dose by the number of doses per day: 1200 mg/day / 3 doses/day = 400 mg/dose  Determine the volume of amoxicillin suspension needed for one dose: Available concentration: 250 mg/5 mL To find the volume for one dose: (400 mg) / (250 mg/5 mL) = 8 mL
