National Physical Therapy Examination (NPTE) Practice Exam

What is the best approach to monitor exertion in a cardiac patient undergoing rehabilitation?

1. Heart rate monitoring

2. Blood pressure measurements

3. Rate of perceived exertion scale

4. Continuous oxygen saturation levels

The correct answer is: Rate of perceived exertion scale

The rate of perceived exertion (RPE) scale is a subjective method for patients to communicate their level of exertion during physical activity. This approach is particularly valuable in cardiac rehabilitation as it takes into account the individual's perception of work, which can be influenced by factors such as fatigue, discomfort, and psychological state. The scale typically ranges from a low number indicating no exertion to a higher number representing maximal exertion. Using the RPE scale allows therapists to tailor the intensity of the exercise program based on the patient's personal experience of their physical activity level, promoting a more individualized and responsive approach to rehabilitation. It helps ensure that patients remain within safe exertion limits while still challenging them appropriately. This method is especially beneficial for cardiac patients who may have varying responses to exercise and need to be cautious about overstressing their cardiovascular system. While heart rate monitoring, blood pressure measurements, and continuous oxygen saturation levels are also important metrics, they are more objective and might not fully capture the patient's subjective experience during exercise. By focusing on perceived exertion, healthcare providers can encourage patient engagement, foster autonomy, and more effectively manage rehabilitation progress.
