A nurse is preparing to administer ciprofloxacin 0.5 g PO to a client who has a postpartum infection. Available is ciprofloxacin 250 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: 0.5 g Conversion factor: 1 g=1000 mg Desired dose (mg) = 0.5 g×1000 mg/g = 500 mg. Available dose: 250 mg/ tablet Calculate the number of tablets to administer per dose. Number of tablets = Desired Dose (mg) / Available Dose (mg/tablet) = 500 mg/250 mg/tablet = 2 tablets.
