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.) .

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 is: Convert the client's weight from pounds (lb) to kilograms (kg). (198 lb ÷ 2.2 kg/lb) = 90 kg. Step 2 is: Calculate the total daily dose of vancomycin in milligrams (mg). 15 mg/kg/day × 90 kg = 1350 mg/day. Step 3 is: Determine the number of doses per day. The medication is given "every 12 hr," so 24 hr/day ÷ 12 hr/dose = 2 doses/day. Step 4 is: Calculate the amount of vancomycin to administer with each dose. 1350 mg/day ÷ 2 doses/day = 675 mg/dose. The final calculated answer is 675 mg.
