ForeverLaur had a valid point. The problem with nursing is that people go into it because "hey, it's only two years, and it's a great paycheck", finish the program, and then realize what absolute hell it is to actually be a nurse. I went into nursing with visions of puppy dogs and roses and helping people, and I, along with the majority of my colleagues, are very burnt out, and yes, considering career changes. A majority of nurses are not practicing - probably for these reasons. So it's not enough to say that the answer is to educate more nurses.
OP - if you want to do nursing because you want to do nursing, that's great. Keep in mind that once you get out of school, the REAL stress begins. Yes, it is rewarding. But those rewarding moments are few and far between. If you love nursing, you'll love it. However, if you just want a career in healthcare and are thinking that nursing will get you more bang for your buck, you'll end up hating it and yes, switching careers. I'm not a fan of the mantra that just because there is a shortage of nurses, anyone should enter the nursing field.
Please don't take this the wrong way. I'm not trying to discourage if this is really what you want to do. I think you should try shadowing a nurse, PA, respiratory therapist, etc. It's not enough to read about job descriptions online.
