Nurses are very important in the promotion of good health for a number of reasons. The first reason that comes to mind is that there there are public health nurses whose sole mission is the promotion of public health. They frequently visit people in their communities to educate them on good health practices and to monitor people's health practices. In private medical practices, nurses are often the people who have more time to spend with patients, discussing the patients' health, educating them about their health, showing them how to take care of themselves. For example, a person who is newly diabetic will usually be taught how to inject insulin, how to monitor blood sugar levels, and how to eat properly. When patients call with questions, it is usually the nurse who answers the questions. It is similar in hospitals, as well, with nurses doing many of the same tasks. There are also many home healthcare nurses who take excellent care of homebound patients and the elderly. I should also mention that the role of nurses in healthcare is expanding significantly because of the economy and because of the aging of our population. My guess is that we would have a much unhealthier population if we did not have nurses.
