Calculate the amount of amoxicillin oral suspension to administer to an 8-year-old male who weighs 54 lb. Ordered: Amoxicillin, oral suspension, 40 mg/kg/day in divided doses q8h On hand: Amoxicillin, oral suspension 250 mg/5 mL

Convert the patient's weight from pounds (lb) to kilograms (kg) Patient's weight in kg = 54 lb / 2.2 lb/kg = 24.5454 kg. Calculate the total daily dose in milligrams (mg). Total daily dose = Ordered dose (mg/kg/day) × Patient's weight (kg) = 40 mg/kg/day × 24.5454 kg = 981.816 mg/day. Calculate the dose per administration (since the medication is given "q8h," which is 3 doses/day). Dose per administration = Total daily dose (mg/day) / 3 doses/day = 981.816 mg / 3 = 327.272 mg/dose. Determine the concentration of the available medication. Available is 250 mg in 5 mL. Concentration = 250 mg / 5 mL = 50 mg/mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Dose per administration (mg) / Concentration (mg/mL) = 327.272 mg / 50 mg/mL = 6.5454 mL/dose. Round the answer to the nearest hundredth. = 6.55 mL/dose.
