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.)
The Correct Answer is ["675"]
-
- 198 lb ÷ 2.205 lb/kg = 90 kg
-
Calculate the total daily dose:
- 15 mg/kg/day * 90 kg = 1350 mg/day
-
Calculate the dose for each 12-hour period:
- 1350 mg/day ÷ 2 doses/day = 675 mg/dose
