I'm guessing that at the facility where you work the nurses pretty much pick up the CNA things (assisting with showering, etc) since you said they don't have CNAs and that they stuck you with janitorial things. I know hospitals definitely use CNAs, but getting on with a hospital is very difficult. I applied uncertified (which wasn't a problem, they were willing to get me certified) but the interview process was a nightmare, and it was my first time applying so I was very unprepared for it. Highly, highly competitive. Not to mention that CNAs are becoming a thing of the past in a sense that there are way too many of them out there fighting for the few jobs available. It's becoming one of those things that one of the nurses could easily pick up. Frankly, I wouldn't have even wasted time or money to get the certification because you can just about wipe your bottom on it these days. What I mean by that is that many nursing schools don't care about your certifications unless you're using them, and as I've already said about that, good luck doing so. I am uncertified and I am doing the same thing a CNA can do for a private family. I take care of their 101 year old mother under the supervision of other employees (CNAs, hospice Rns, etc) who come and go during the week to check on her. I will have the experience without having wasted time and money on certification (I just couldn't do it with having to work, take classes, etc). Now, that is what I recommend you do if you're not liking your current job. Make friends with some nurses ("who you know" is everything these days). See if they could recommend you to any patients who need sitters and caregivers. Contact hospice. They hire a lot of CNAs also.
Now, to your question about fun. Is nursing, or any healthcare profession fun. Well, I guess that really depends on how you define fun. I don't think wiping someone else's bottom and getting bodily fluids on my clothes fun, but I thoroughly enjoy what I do. I like caring for people, I like the science behind nursing and medicine. I feel fulfilled in my career path. Exciting, well, hmm. You have trauma surgeons for example, the ER. If you want exciting, you can go down into the ER, which every other department calls the "Jungle." I guarantee you'll never have a dull moment down there. I volunteered in that department twice and loved it. In the end, I don't really know what you expect to get out of this, but I will say that you get out what you put in. Now, if you think this is something you won't like (you should just have a gut feeling about it) then maybe it's not for you. An example? My boyfriend is an econ major, and he is perfectly happy sitting at a desk and staring at a computer all day. Now, I know that would absolutely bore me to tears. I need to be up moving about, interacting with people, keeping busy. I'm lazy, but I'm not sedentary. I think more hands on experience outside of housekeeping will give you a good idea. And if you can't get an idea with your certificate, volunteer instead and shadow some health professionals. Hope this helps
