Ati peds drug dosage calculation assessment proctored exam
A nurse is preparing to administer cefaclor to a toddler who weighs 33 pounds. The prescribed dosage is 20 mg/kg/day PO, divided into two doses every 12 hours. The available cefaclor oral suspension contains 125 mg per 5 mL. How many milliliters should the nurse administer per dose? (Round to the nearest whole number.)
Explanation & Rationale
Identify the child's weight and convert from pounds (lbs) to kilograms (kg) Weight: 33 lbs Conversion: 33 / 2.2 = 15 kg Calculate the total daily dose in mg Daily Dose = 15 kg * 20 mg/kg/day Daily Dose = 300 mg/day Calculate the dose per administration (Frequency: every 12 hours) Doses per day = 24 / 12 = 2 doses Single Dose = 300 mg / 2 Single Dose = 150 mg Calculate the volume to administer in mL Volume = (Single Dose / Available mg) * Available Volume Volume = (150 / 125) * 5 Volume = 1.2 * 5 = 6 mL
