I've been a CNA for 2 years and was a PCA for six. I found that by working in the hospital in the Surg Unit, helped expand my knowledge and boosted my interest in the nursing field. I'm currently half way through school to get my RN, and continue to work on the Surg Unit. I find this invaluable expierence and plan on working on the unit as an RN. The nurses are so great in explaining what they do to me, so i feel as though I'll be in a great position when I become a nurse. I also encourage people to become a CNA before or during school to become an RN. This way you're exposed to what a CNA and nurses really do, and to see if this is the right field for you before spending thousands on schooling.
