Elevated BUN and creatinine levels may indicate which condition?

• A. Nephrotoxicity
• B. Hepatotoxicity
• C. Cardiac toxicity
• D. Neuropathy

Answer: (A)

Elevated BUN and creatinine mean the kidneys aren’t filtering waste effectively, signaling renal injury or dysfunction. Nephrotoxicity is the condition most closely tied to this lab pattern because direct damage to the kidneys from drugs, toxins, or impaired perfusion reduces glomerular filtration, allowing waste products to build up in the blood. In contrast, hepatotoxicity would raise liver-specific markers rather than BUN and creatinine, cardiac toxicity relates to heart function, and neuropathy involves nerves, not kidney waste clearance. So the rise in these two waste products directly points to nephrotoxicity.
