It's true that a lot of hospitals want a BSN, and it would be better to go for your Bachelor degree. But, hospitals will still hire Nurses with an Associate's, they will probably make you sign an agreement stating that you will return to school to get your BSN within 5 years of being hired. That's what the hospital that I work at does, and they've hired many ADN's.
Most job advertisements say BSN preferred, but some will definitely hire ADN as well. A few of my coworkers had their ADN, started working, and then did a RN to BSN program while they worked. So if you are able to, your best bet is to go for your BSN now, because your most likely going to have to do it later anyway. The jobs are out there for ADN's, and the starting pay is usually no different whether you have an ADN or BSN.
