As far as working as a PRN CNA while in school, you might be wise to go ahead and do that. You would be surprised how many call off "sick" in the health care field, and could very easily end up with more hours than you actually want! I think one of the reasons they might offer PRN is so you are not receiving benefits such as health insurance, and with you being under your mothers wing, you probably don't need it.
Second, if you are in a facility as a CNA, you already have your foot in that door toward having a potential job as an RN once you get your degree. Then, after some experience both as a CNA and RN< it will be much easier for you to find other employment if you choose to leave that facility.
Thirdly, if you are staying at your mothers or even out on your own, depending on financial circumstances, you can receive substantial grants which is money you don't have to pay back- towards your education. Pell Grant and O'Bannon Grant (in Indiana) are two that come to mind. You can also apply for other scholarships
- sometimes by just writing a paper about a specific topic or something. This is also free money. Incidentally, the better your grades in high school, the better the chances of receiving scholarships. I know a student that is going to Valpo for a 4 yr degree in nursing and has full scholarship
there. I think his schooling is going to only cost about 4,000.00 a year and that is on campus!
There are surpluses of nurses in a lot of areas, including mine- but there are pockets of areas where they are needed...small town hospitals and such. And nursing homes have a high turn over rate, depending on the facility and how much they actually care.
Hope this helps!
