A stress test is used to determine the presence of what condition?

• A. Liver disease
• B. Kidney disease
• C. Cardiac disease or disorder
• D. Neurological disease

Answer: (C)

A stress test evaluates how the heart responds to exercise or increased demand to reveal heart problems that might not be evident at rest. During the test, you monitor the heart’s electrical activity, heart rate, blood pressure, and symptoms as you exercise (or receive a controlled stimulant). If the heart isn’t receiving enough blood during exertion because of narrowed arteries, you may see chest pain, dizziness, shortness of breath, or abnormal ECG changes. This helps identify cardiac conditions such as coronary artery disease and guides risk assessment and management. It’s not used to diagnose liver, kidney, or neurological diseases, which require different tests and evaluations.
