A nurse is preparing to administer acetaminophen 0.65 g PO to a client for a report of postpartum pain. Available is acetaminophen 325 mg tablets. How many tablets should the nurse plan to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Convert the desired dose from grams (g) to milligrams (mg). Desired dose 0.65 g Conversion factor: 1 g=1000 mg Desired dose (mg) = 0.65 g×1000 mg/g = 650 mg. Calculate the number of tablets to administer per dose. Number of tablets = Desired Dose (mg) / Available Dose (mg/tablet) = 650 mg/325 mg/tablet = 2 tablets.
