i do know a co-worker that grad from adn-rn, she couldnt find an rn job to save her life for about a yr. she passed boards, continued to work as cna. she was held to the standards of rn, and could get in "trouble" as an rn for something she did as a cna. there is another aspect that ppl will take advantage of the situ as well, not usually in a good way. so make sure you are able to stand your ground. it is not in your best interest from what i have read and discussed where i work, but sometimes you have to do what you have to do, kwim? and as the other person said, you kinda mess yourself up b/c you get paid at lvn, but will be expected to do rn.
