A nurse is preparing to administer metronidazole 7.5 mg/kg PO to a client who weighs 146.7 lb. Available is metronidazole 500 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.)

Convert the client's weight from pounds (lb) to kilograms (kg). Client weight (kg) = 146.7 lb / 2.2 lb/kg = 66.68 kg. Calculate the total dose in milligrams (mg). Total dose (mg) = Client weight (kg) x Ordered dose (mg/kg) = 66.68 kg x 7.5 mg/kg = 500.1 mg. Calculate the number of tablets to administer. Number of tablets = Total dose (mg) / Available strength (mg/tablet) = 500.1 mg / 500 mg/tablet = 1.0002 tablets. Round to the nearest whole number. = 1 tablet.
