A nurse prepares 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.)

Answer and Explanation

The Correct Answer is ["675"]

To calculate the dosage of vancomycin, we first convert the client's weight from pounds to kilograms, knowing that 1 kilogram is approximately 2.2 pounds. The client weighs 198 pounds, which is equivalent to about 90 kilograms (198 lb / 2.2). The prescribed dose is 15 mg/kg/day, so for a 90 kg individual, this would be 1350 mg/day (15 mg/kg * 90 kg). Since the dose is divided equally every 12 hours, the nurse would administer half of the daily dose every 12 hours, resulting in 675 mg per dose (1350 mg/day / 2). Therefore, the nurse should administer 675 mg of vancomycin with each dose.

C. Furosemide is a diuretic that does not directly substitute for the actions of ACE inhibitors.

D. Hydralazine is a direct vasodilator used for hypertension but does not share the same mechanism as ACE inhibitors or serve as a direct alternative.
