The Power of a Health Care Advocate
"The complexity of the health care system has given rise to a new professional: the patient advocate. This person is often a nurse, social worker, geriatric care manager or other health care professional who can help you navigate the health care system, including dealing with clinicians, understanding your condition and treatment options, and even helping with health insurance issues. Patient advocates generally charge about $125 an hour, according to Elisabeth Schuler Russell, a health care consultant."
Looks like it's reserved for the elderly when needing a second opinion about proper treatment and where to go. I probably would have no idea if I hadn't looked this up, but I mean my default answer without background knowledge would be yes. I guess they're trying to quiz you on terminology? By default I guess you're a healthcare advocate for your patients because you're usually the first medical opinion.
