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? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: A

Rationale:
To calculate the vancomycin dose, convert the client's weight from pounds to kilograms: 198 lb ÷ 2.2 = 90 kg. Multiply the weight by the dose (15 mg/kg/day): 90 kg × 15 mg/kg/day = 1350 mg/day. Since this dose is divided equally every 12 hours, divide the total daily dose by 2 to get the dose per administration: 1350 mg/day ÷ 2 = 675 mg.
Therefore, the nurse should administer 675 mg with each dose.
Choice A (675 mg) is correct because it follows the appropriate calculations for determining the vancomycin dose based on the client's weight. Other choices are incorrect as they do not align with the correct calculation process.
