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.)

Convert the total daily dose from grams (gm) to milligrams (mg). Total daily dose in mg = 2 gm × 1000 mg/gm = 2000 mg/day. Determine the dose per administration. The total daily dose is divided into two doses. Dose per administration = 2000 mg/day / 2 doses/day = 1000 mg/dose. Available strength of each tablet = 500 mg/tablet. Calculate the number of tablets to administer with each dose. Number of tablets per dose = Dose per administration (mg) / Available strength (mg/tablet) = 1000 mg / 500 mg/tablet = 2 tablets.
