As a physician, I have been able to watch the process that you speak of up close. Actually, it is not necessary for one to work as a nursing aide before beginning one's R.N. training. Now having said this, it is advantageous if one does have some nursing experience before making a decision to become an RN, if for no other reason, one has given one's self a chance to "be sure" that one wants to do Nursing, as a professional, as a life-time career. It one works as a nursing aide, one will see what an RN does, and one will find out if one has the "inclination, talent, and work ethic (not to mention the commitment)," to do the work of an RN. By the way, when I was a young person, struggling with my preparation to become a physician, my friends in Norway, who where also preparing to go to med school, had to work as "orderlies," another name for nursing aides, back in those days, before they were allowed to inter medical school. They had to work in the role of orderly for 1 year at least. I am not saying that you need to work in that role for one year before going to nursing school. Within a few months, one will know, whether or not, one likes nursing. I hope that my answer has helped. Good luck, in your quest to become a RN. I love nurses, all nurses, including nursing aides, practical nurses and RNs. They always impress me with their level of commitment, dedication, professionalism and character.
