Question 1 of 5
A child who weighs 18 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labelled, 'Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.' How many mL should the nurse administer with each dose?
Correct Answer: A
Rationale: The dose is calculated as 18 lbs ÷ 2.2 = 8.18 kg, 25 mg/kg/day x 8.18 kg = 204.5 mg/day, divided into 102.25 mg/dose.
Then, 102.25 mg ÷ (400 mg/5 mL) = 1.3 mL.
