A nurse is preparing to administer lamivudine 150 mg PO BID. Available is lamivudine 100 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Desired dose per administration = 150 mg. Available strength of each tablet = 100 mg/tablet. Calculate the number of tablets to administer per dose. Number of tablets per dose = Desired dose (mg) / Available strength (mg/tablet) = 150 mg / 100 mg/tablet = 1.5 tablets.
