Hey, I'd love to go into that field (either nursing or as a paramedic) but...I'm squeamish as I can be.
In that case, allow me to suggest a healthcare field that is expanding, well-paid and doesn't require working with icky bodily fluids: physical therapy.
As the baby boomers get older, they are requiring more physical therapy. Much like nursing, the demand exceeds the supply. Some PT schools, in an attempt to "raise the standards of the profession" (i.e.: reduce the supply and increase the demand) are now only offering a doctorate in physical therapy. But there are still schools out there that provide a bachelor's. I suspect that sooner or later, PT will follow the lead of the pharmacists and only offer a 5 or 6 year doctorate degree as the only means of entry into the profession. Pharmacy did that years ago, and it has been very, very successful in raising salaries due to the decreased supply. A new pharmacist right out of school can make $ 90,000/year working at Walgreen's, Rite Aid or the like.
