National Physical Therapy Examination (NPTE) Practice Exam

In the context of cardiac rehabilitation, which of the following would be considered a sign of exercise intolerance?

1. Stable vital signs through the session

2. Decreased range of motion

3. Elevated heart rate and blood pressure

4. Behavioral changes during activities

The correct answer is: Elevated heart rate and blood pressure

In the context of cardiac rehabilitation, elevated heart rate and blood pressure during exercise are significant indicators of exercise intolerance. When a patient experiences an abnormal increase in heart rate and blood pressure in response to physical activity, it suggests that their cardiovascular system may not be able to handle the exertion effectively. This could be due to underlying cardiac issues or a lack of physical conditioning, and it may signal the need to adjust the intensity of the exercise program or closely monitor the patient's response to exercise. This response to exercise is critical because maintaining safe levels of vital signs is essential for preventing adverse events during rehabilitation. Stable vital signs throughout the session would indicate good tolerance to the exercise, while decreased range of motion doesn't directly relate to cardiovascular response and may pertain more to musculoskeletal issues. Behavioral changes during activities may indicate discomfort or psychological factors but do not specifically inform about the cardiovascular response to exercise in the same manner as vital sign changes.
