A child receiving amoxicillin 500 mg PO every 12 hr
Question 1 of 5
A nurse is preparing to administer amoxicillin 500 mg PO every 12 hr. The amount available is amoxicillin 250 mg/5 mL suspension. How many mL should the nurse administer?
Correct Answer: B
Rationale: The correct answer is B: 10 mL.
To calculate, first determine the total daily dose of amoxicillin, which is 1000 mg (500 mg every 12 hours). Next, calculate how many mg are in 1 mL of the suspension, which is 250 mg/5 mL = 50 mg/mL. Divide the total daily dose by the mg/mL concentration: 1000 mg / 50 mg/mL = 20 mL. Since the dose is given every 12 hours, divide the total by 2 to get the dose for each administration: 20 mL / 2 = 10 mL every 12 hours.
Choice A (5 mL) is incorrect because it does not provide the full dose required.
Choice C (15 mL) and D (20 mL) are incorrect as they exceed the required dose.
