In a symptom-limited exercise test, termination is primarily based on which criterion?

• A. Signs or symptoms indicating risk.
• B. A predismissed duration regardless of symptoms.
• C. The weather outside.
• D. The color of the patient's clothing.

Answer: (A)

The test ends when the patient’s response to exercise indicates they cannot continue safely. In a symptom-limited exercise test, clinicians monitor for signs and symptoms that reflect potential risk or intolerable effort—anger chest pain or angina, marked shortness of breath, dizziness or fainting, extreme fatigue, or abnormal or unsafe blood pressure or ECG changes. When these occur, stopping the test protects the patient. This differs from a fixed-duration protocol that ends at a preset time or workload regardless of how the person feels. External factors like weather or the color of clothing are not relevant to the decision to stop, since they don’t reflect the patient’s physiological response during exercise.
