Before starting vancomycin therapy, which baseline assessment is important?

• A. Body temperature
• B. Serum creatinine
• C. Bowel sounds
• D. Oxygen saturation

Answer: (B)

Vancomycin is cleared from the body mainly by the kidneys, so knowing kidney function before starting therapy is essential. Serum creatinine provides a snapshot of renal function; a higher creatinine or lower creatinine clearance signals reduced drug elimination. This helps determine the initial dose and how often to give it, and it sets the stage for later monitoring of drug levels to avoid accumulation and nephrotoxicity. If renal function is impaired, dosing must be adjusted and closer monitoring is needed. While temperature, bowel sounds, and oxygen saturation offer important clinical information, they don’t directly impact safe dosing or nephrotoxicity risk in the way baseline renal function does.
