A nurse is administering azithromycin 10 mg/kg PO to a toddler who weighs 27 lb. Available is azithromycin suspension 200 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step by step calculation: The child's weight is 27 lb. The medication dosage is 10 mg/kg. The available medication concentration is 200 mg/5 mL. Calculating the total dose in mg: Convert the child's weight to kg: 27 lb ÷ 2.2 lb/kg = 12.27 kg Calculate the total dose: 12.27 kg × 10 mg/kg = 122.7 mg Calculating the volume to administer: Use the concentration of the medication: 122.7 mg ÷ (200 mg/5 mL) = 122.7 mg ÷ 40 mg/mL = 3.0675 mL Rounding the answer: 3.0675 rounds to 3 mL
