Question

Quizplus · Accepted Answer

To physically recondition a patient and increase exercise tolerance, all three choices listed are necessary. Improving the body's overall oxygen utilization (I) means that the patient will be able to take in and use oxygen more efficiently during exercise, which can increase their overall exercise performance. Strengthening the essential muscle groups (II) will help the patient to better perform specific movements and reduce the risk of injury. Enhancing the cardiovascular response to exercise (III) means that the patient's heart and lungs will work more efficiently together during exercise, allowing them to sustain higher levels of activity for longer periods of time.
