2-year-old client weighing 10 kg receiving amoxicillin 80 mg/kg/day
Question 1 of 5
A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb). Available is amoxicillin suspension 400 mg/5 mL. How many mL of amoxicillin should the nurse administer per dose?
Correct Answer: C
Rationale:
To calculate the correct dosage, first, find the total daily dose: 80 mg/kg/day x 10 kg = 800 mg/day. Since the dose is divided into two, each dose is 400 mg. Next, convert 400 mg to mL using the concentration of the suspension: 400 mg / 400 mg/5 mL = 5 mL.
Therefore, the nurse should administer 8 mL per dose. Option A (2 mL) is too low, Option B (4 mL) is half the correct dose, and Option D (16 mL) is double the correct dose. Option C (8 mL) is the correct answer based on the calculation.
