I am currently a CNA and have started taking my pre-requisites for nursing school
. I really recommend being a CNA. I got a job at the hospital on a surgical unit and have experienced so many things that I never thought I would have as a CNA. I work along side the nurses on our floor and on top of the ADLs, we empty drains, take vital signs and dc foley catheters. Nurses can always use an extra set of hands when doing large dressing changes, inserting NGs, pulling drains, etc.
We get nursing students on our floor every once in a while and I see them struggle with patient interaction and basic skills that CNAs already know. I think that having been a CNA will put you at a huge advantage in terms of nursing school. I can easily spot out the nursing students that have been CNAs.
Having said this, your CNA experience can be SO different depending on where you are. I don't recommend working at a nursing home if you plan to work in a hospital as a nurse. So many CNAs I know have been turned off a healthcare due to the terrible experiences they have had working at nursing homes. You are underpaid, overworked and not appreciated for all the work you do (I have never worked in a nursing home so this is just from all the stories I have heard).
I'm sure either way you will learn a lot of things that will prepare you for being an RN!!
