How can nursing address and improve global healthcare needs?
Well, I'm not sure that nurses are able to work in ANY health care situation unless the proper training has been applied. But, we are able to call on other resources to complete care.
Now in a global situation, start at home, say in rural areas such as Kentucky or Mississipi, or even a native reservation, we can look at a patient, assess them and what their needs are. Someone in these areas have a lack of access to health care. So perhaps a newly diagnosed diabetic would require teaching from you and be given access to public resources for government assistance like food, money and living to name a few.
In a more global sense, the AIDS crisis is a good example. People need education about prevention. If they are already infected they need someone to administer medications, food and water, treatments for wounds, counseling on issues like rape, which all should be done to the entire family holistically or even whole villages.
Nurses are able to bring together resources to provide holistic health care to patients in any country provided we have translators or other tools to cross language barriers.
I hope I wasn't rambling too much and was able to help.
