P.N.
There are several reputable online programs where you can begin your classes to work toward your RN. You can't complete an ASN or BSN online because of the clinical aspect of your training, obviously.
I am an RN, a manager, and do hire RNs for a major hospital corporation. If you have earned the credentials "RN", then you have passed the standardized national exam called the NCLEX, and you are qualified to take most entry level RN jobs. In my experience, I don't know of too many hiring managers who care much where you went to school because, as I said, the ASN or BSN is one thing, but to have the "RN", you took and passed the same exam the rest of us did. Do what you can online if it works for you and your family.
As far as whether to get a 2 year Associate's degree or a 4 year Bachelor's (both degrees will culminate in you taking the same NCLEX, and having an "RN"behind your name, with no distinction as to whether you have the ASN or BSN, except on your resume), there are some changes happening with nursing degrees, but from my research so far, the changes are mostly addressing a Master's and a Doctorate in nursing, and not the ASN. Yet. Talk with a guidance councelor at a local college, OR, get online and contact the American Nurse's Association for the most up-to-date info on whether the ASN is still worth looking into. If it is, I highly recommend that route. The BSN allows you to go into management roles more easily, but with the going RN hourly rate at right around $30/hr to start, you'd be making over $60,000 right out of school!
Good luck!
