In asymptomatic patients with mild comorbidity undergoing low-risk surgery, which test is NOT routinely indicated preoperatively?

• A. Electrocardiogram
• B. Chest X-ray
• C. Basic metabolic panel
• D. Routine stress testing

Answer: (D)

The main idea is that testing should be guided by symptoms and risk, not done routinely for every patient. In someone with only mild comorbidity who is undergoing a low-risk operation, the chance that a routine preoperative stress test will change management or improve outcomes is very small. Exercise or pharmacologic stress testing is designed to detect significant coronary disease that would alter perioperative planning, and in this low-risk, asymptomatic group it has a high chance of false positives or incidental findings that lead to unnecessary delays, additional tests, and patient anxiety. Therefore it’s not routinely indicated. Other tests can be reasonable in specific contexts: an electrocardiogram or chest X-ray might be considered if there are known cardiac issues, relevant risk factors, or abnormal history/physical exam; a basic metabolic panel helps assess electrolyte status and renal function when indicated by comorbidities or medications. But routine stress testing in asymptomatic, low-risk patients does not provide meaningful benefit and is not recommended.
