Question 1 of 5
A nurse is preparing to administer amoxicillin 2 gm/day PO divided into two doses. The amount available is amoxicillin 500 mg tablets. How many tablets 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: B
Rationale: The correct answer is B: 2 tablets.
To achieve a total daily dose of 2 gm/day, the nurse needs to administer 1000 mg per dose. Since each tablet is 500 mg, the nurse should administer 2 tablets per dose (500 mg + 500 mg = 1000 mg). This ensures the patient receives the prescribed total daily dose of amoxicillin.
Incorrect choices:
A: 1 tablet would only provide 500 mg, which is half of the required dose.
C: 3 tablets would exceed the required dose, giving 1500 mg per dose.
D: 4 tablets would provide 2000 mg, which is double the required dose.
Therefore, choices A, C, and D are incorrect based on the prescribed dose of 2 gm/day divided into two doses.
