Cardiac-Vascular Nursing (CVRN) Practice Exam

What benefit can a patient recovering from a myocardial infarction gain from meditation?

1. Increases sympathetic nervous system activity.

2. Decreases sympathetic nervous system activity.

3. Increases the release of catecholamines.

4. Decreases vasodilation.

The correct answer is: Decreases sympathetic nervous system activity.

Meditation can significantly benefit a patient recovering from a myocardial infarction by decreasing sympathetic nervous system activity. This reduction leads to various physiological advantages, especially in the context of heart health. When the sympathetic nervous system is activated, it can lead to increased heart rate, elevated blood pressure, and higher levels of stress hormones like catecholamines. All of these can pose risks for a patient in recovery from a heart attack. Conversely, meditation fosters a state of relaxation and mindfulness, which directly counteracts the stress response associated with sympathetic activation. As the sympathetic activity decreases, the patient may experience improved heart rate variability, lower blood pressure, and a calming effect that can aid in their overall recovery. This shift can also promote better mental health and emotional well-being, which are essential components of cardiac rehabilitation. In summary, the therapeutic practice of meditation intertwines with heart health by mitigating stress responses, supporting more favorable cardiovascular outcomes, and contributing to the overall recovery journey post-myocardial infarction.
