Question 1 of 5

A nurse is preparing to administer amoxicillin 75 mg/kg/day divided equally every 8 hr to a child who weighs 20 kg. Available is amoxicillin oral suspension 250 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 10 mL

Rationale:
To calculate the dose, first, determine the total daily dose: 75 mg/kg/day x 20 kg = 1500 mg/day.
Then, divide this by the number of doses per day (3) to get 500 mg per dose. Next, convert this to mL using the concentration of the oral suspension (250 mg/5 mL). 500 mg ÷ 250 mg/5 mL = 10 mL.
Therefore, the correct answer is 10 mL.

Choice A is incorrect as it doesn't follow the correct calculation steps.

Choices B-G are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the oral suspension.
