Certified Rehabilitation Registered Nurse (CRRN) Practice Exam

What is the key focus of a cardiac rehabilitation exercise program post-myocardial infarction?

1. Immediate high-intensity exercise

2. Gradually increasing exercise after cardiac testing

3. Avoiding any physical activity

4. Limit exercises to respiratory training only

The correct answer is: Gradually increasing exercise after cardiac testing

The key focus of a cardiac rehabilitation exercise program post-myocardial infarction is to gradually increase exercise after cardiac testing. This approach is essential because it helps ensure that patients safely regain their strength and cardiovascular fitness following a heart attack. After a myocardial infarction, the heart is in a vulnerable state, and a structured, progressive rehabilitation program allows healthcare providers to carefully monitor a patient's response to increasing levels of physical activity. This helps to build endurance, improve muscle strength, and optimize cardiovascular function while minimizing the risk of complications. Cardiac testing, such as a stress test, provides valuable information about the patient's current heart function and safe exertion levels, enabling personalization of the exercise program. Gradually increasing exercise fosters a safe environment for recovery, as it allows patients to acclimate to physical activity in a controlled manner, enhancing both physical and psychological resilience. Overall, this focus on controlled progression is a foundational principle in cardiac rehabilitation, aimed at maximizing patient outcomes and long-term heart health.
