A nurse is preparing to administer vancomycin 15 mg/kg/day divided equally every 12 hours. The client weighs 198 lb. How many mg should the nurse administer with each dose?
Correct answer
675
Rationale
Correct Answer: 675
Rationale:
1. Convert weight from lb to kg: 198 lb ├À 2.2 = 90 kg.
2. Calculate total daily dose: 15 mg/kg/day x 90 kg = 1350 mg/day.
3. Divide total daily dose by 2 for equal doses every 12 hours: 1350 mg/2 = 675 mg per dose.
Summary:
A, B, C, D, E, F, G: These options do not follow the correct calculation steps. A, B, C, D, E, F, G are incorrect because they do not consider the weight conversion, total daily dose calculation, and dosage frequency requirements.
