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.)
The Correct Answer is ["3"]
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

Correct Answer is ["15"]
Explanation
Step-by-step calculation:
The child's weight is 55 lb.
The medication dosage is 15 mg/kg.
The available medication concentration is 125 mg/5 mL.
Calculating the total dose in mg:
Convert the child's weight to kg: 55 lb ÷ 2.2 lb/kg = 25 kg
Calculate the total dose: 25 kg × 15 mg/kg = 375 mg
Calculating the volume to administer:
Use the concentration of the medication: 375 mg ÷ (125 mg/5 mL) = 375 mg ÷ 25 mg/mL = 15 mL
