How is this different from asking a friend to write your paper for you? Do you have an honor code at your school? If there is, you're breaking it. Not to mention you are loosing your chance to develop critical thinking skills when you go about your assignments this way. If you can't do this assignment yourself, you can't do the next one and so on until you learn how to do it yourself. Take charge of your life--research it yourself.
If you want to showcase a nurse's personal perspective in quotes, you can do that here. But the broad impersonal questions you are asking are meant to be researched from a variety of places and answered by you, citing the sources of that information.
Here's a start for your research:
American Nurses Association
You'll find all the information and links you need there. Or just google the topics in your questions.
Plagarism is more than copying words, it is copying ideas.
Furthermore, critical thinking involves being able to evaluate and verify the sources of your information, so this is not the place to do it. I could tell you that anyone over the age of 16 can just take a 50 question online test to become an RN and you could believe me.
Now go to a reliable source like the one above to find out if that is true.
