Which preoperative test is least likely required for nonpregnant adults?

• A. Lipid panel
• B. CBC
• C. BMP
• D. Type Screen

Answer: (A)

The key idea is that preoperative testing should be guided by how the results would change perioperative management. CBC, BMP, and a type and screen provide information that can directly influence anesthesia and intraoperative or transfusion decisions: CBC checks for anemia and infection risk, BMP assesses kidney function and electrolyte balance that can affect drug handling and rhythm stability, and a type and screen prepares for the real possibility of needing a transfusion. A lipid panel, while important for long-term cardiovascular risk assessment, does not typically change immediate perioperative planning for nonpregnant adults undergoing standard procedures. It’s not routinely required unless there’s a specific cardiovascular risk factor or plan to adjust management based on lipid abnormalities. Therefore, the lipid panel is the least likely to be needed preoperatively.
