A nurse is preparing to administer amoxicillin 500 mg PO. Available is amoxicillin 250 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is 2 tablets. Step 1 is to divide the prescribed dose by the available dose. So, 500 mg ÷ 250 mg = 2. Rationale: The nurse needs to administer the amount of medication that will equal the prescribed dose. Since each tablet contains 250 mg of amoxicillin, two tablets will provide the 500 mg dose. So, the correct answer is 2 tablets.
