A nurse is preparing to administer vancomycin 15 mg/kg/day divided equally every 12 hr. The client weighs 198 lb. How many mg 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.)

Step 1: Convert weight from pounds to kilograms Weight in kg = 198 ÷ 2.2 = 90 kg Step 2: Calculate total daily dose 15 mg/kg/day × 90 kg = 1,350 mg/day Step 3: Divide the total daily dose by 2 (since the medication is given every 12 hours) 1,350 ÷ 2 = 675 mg per dose Final Answer: 675 mg
