What is the most common intervention for autonomic dysfunction syndrome?

1. Oral hydration

2. IV morphine

3. Beta-blockers

4. Physical therapy

The correct answer is: IV morphine

The most common intervention for autonomic dysfunction syndrome is oral hydration. This approach is essential because individuals with autonomic dysfunction often experience issues with blood pressure regulation and volume status due to impaired autonomic regulation. Administering oral fluids aids in managing symptoms such as orthostatic hypotension, where blood pressure drops when a person stands up, leading to dizziness or fainting. Proper hydration helps optimize blood volume and improve circulation, making it a first-line intervention in many cases of autonomic dysfunction. In contrast, IV morphine, while effective for pain management, does not address the underlying issues presented by autonomic dysfunction. Beta-blockers can be used in certain situations to manage heart rate and blood pressure but are not the primary intervention for the condition as a whole. Physical therapy may assist with strengthening and improving overall mobility but does not address the immediate needs related to autonomic stability and hydration. Therefore, while other choices may have roles in managing symptoms, they do not serve as the most common or foundational intervention for autonomic dysfunction syndrome.
