Hi, mercurygirl!
I'm going to give you a bunch of links to information for you to read so you know what the job descriptions of a CNA (nursing assistant), LPN and RN are. I am also giving you the websites where you can get lots of information about nursing and how to become a nurse. On the Discover Nursing website you will find a link there that has a listing of the many different areas in nursing that you can work in with more links to get more information about them. Because being an RN generally means going to a college I usually advise people to go to the collegeboard website (it's listed below). Although it is the primarily known as the website to get information for the S.A.T. and C.L.E.P. exams it also has a great deal of information on what you need to do to choose a college and get into a college. I would also encourage you to do a websearch and go to the website for your state Department of Education. Some states have special programs and financial assistance in place for adults who want to go back to school to become trained in a career. You should also check the website of your state board of LPN/RN nursing to see if there are any scholarships available. Because of the current nursing shortage that is expected to remain, there are a number of organizations that are doing what they can to assist future nurses finance their nursing educations in many different ways. You can find your state board of nursing website link through allnurses by rolling your mouse over the "Links" button at the top right of this page if you are logged in. A drop down menu will appear. Click on "Boards of Nursing". A page of states will come up. Click on your state. A link to your state board of nursing will come up. I also suggest that you begin hanging out and reading what the Pre-nursing students have to say and what they are going through to prepare for admission to a nursing school on the Pre-nursing Forum on allnurses. You might also check out the CNA-Nursing Assistant Forum on allnurses as well to find out how to become a CNA and what being a CNA entails.
Good luck! Welcome to allnurses!
