Calculation
A nurse is preparing to administer ceftazidime 40 mg/kg IV bolus every 8 hr to a school-age child who weighs 77 lb. Available is ceftazidime injection 40 mg/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.)
mL
Explanation & Rationale
Step by step calculation: Calculating the total dose in mg: Convert the child's weight to kg: 77 lb ÷ 2.2 lb/kg = 35 kg Calculate the total dose: 35 kg × 40 mg/kg = 1400 mg Calculating the volume to administer: Use the concentration of the medication: 1400 mg ÷ 40 mg/mL = 35 mL
