National Physical Therapy Examination (NPTE) Practice Exam

In phase III of a cardiac rehabilitation program, which intervention is most appropriate for a group exercise setting?

1. Slowly performing active range of motion activities of the upper and lower extremities

2. Resistance exercises using less than 15 pounds when in a sitting position

3. Running on a treadmill at 5 mph

4. Walking on a treadmill at 2 mph

The correct answer is: Resistance exercises using less than 15 pounds when in a sitting position

In phase III of a cardiac rehabilitation program, patients have typically progressed from supervised care to a more independent exercise setting, where the focus is on enhancing physical fitness and promoting safe exercise practices. Performing resistance exercises is particularly important during this phase, as it helps patients to build strength and improve function, as well as to enhance their overall cardiovascular fitness. Resistance exercises using less than 15 pounds while in a sitting position are appropriate because they allow for controlled movements that minimize the risk of injury, particularly for individuals who may still be managing cardiac conditions. This position also offers stability and support, enabling participants to focus on their form and breathing, which is crucial for cardiac patients to ensure they do not exceed their limits and maintain an appropriate level of exertion. In contrast, options like running on a treadmill and walking at higher speeds may exceed the safe exercise intensity for some patients in phase III, particularly depending on their individual fitness levels and cardiac status. These activities may increase heart rate significantly and carry a higher risk of undue stress on the cardiovascular system. Active range of motion activities, while important, are generally more suited for earlier phases of rehabilitation where mobility and flexibility are the primary goals rather than strength and endurance. As a result, resistance exercises in a seated position are
