The nurse is preparing to administer the fourth dose of IV vancomycin to a client. Which set of laboratory values would alert the nurse to hold the vancomycin and notify the health care provider?
- A. Vancomycin trough 10 mg/L (6.9 umol/L), creatinine 1.1 mg/dL (97.2 umol/L), BUN 6 mg/dL (2.1 mmol/L)
- B. Vancomycin trough 14 mg/L (9.7 umol/L), creatinine 1.2 mg/dL (106.1 umol/L), BUN 10 mg/dL (3.6 mmol/L)
- C. Vancomycin trough 18 mg/L (12.4 umol/L), creatinine 0.6 mg/dL (53 umol/L), BUN 18 mg/dL (6.4 mmol/L)
- D. Vancomycin trough 23 mg/L (15.9 umol/L), creatinine 1.5 mg/dL (132.6 umol/L), BUN 24 mg/dL (8.6 mmol/L)
Correct Answer: D
Rationale: A vancomycin trough of 23 mg/L is above the therapeutic range (10-20 mg/L), indicating potential toxicity. Elevated creatinine (1.5 mg/dL) suggests renal impairment, which increases the risk of vancomycin accumulation and nephrotoxicity.
