Which finding should prompt immediate intervention when caring for a patient on IV vancomycin?

• A. Vancomycin trough level of 10 mg/L
• B. Creatinine level of 1.1 mg/dL
• C. BUN level of 10 mg/dL
• D. Vancomycin trough level of 23 mg/L

Answer: (D)

A vancomycin trough level of 23 mg/L indicates that the patient is experiencing elevated levels of this medication, which can lead to toxicity. The therapeutic range for vancomycin trough levels typically falls between 10 to 20 mg/L, depending on the infection being treated. Levels higher than this range can increase the risk of adverse effects, such as nephrotoxicity and ototoxicity. Immediate intervention is warranted in this case because a trough level of 23 mg/L is significantly above the recommended range and could indicate an accumulation of the drug in the body. This situation requires prompt evaluation, which may include adjusting the IV vancomycin dosage, implementing additional monitoring for renal function, and assessing the patient for any symptoms of toxicity. Monitoring the patient's renal function—via Creatinine and BUN levels—is also important, but those values presented in the other options do not suggest immediate risk like the elevated trough level does.
