Question 1 of 5
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?
Correct Answer: A
Rationale:
To calculate the vancomycin dose, first convert the client's weight from lb to kg: 198 lb / 2.2 = 90 kg.
Then, multiply the weight by the dose: 90 kg x 15 mg/kg/day = 1350 mg/day. Since the dose is divided equally every 12 hours, divide the total daily dose by 2: 1350 mg/day / 2 = 675 mg per dose.
Therefore, the correct answer is A: 675 mg. Other choices are incorrect as they do not follow the correct calculation process.
