I have worked in critical access for 10 of my 15 years in nursing. I couldn't imagine working in any other environment! Critical access hospitals get everything the big hospitals get, just fewer and farther between. We are like a MASH unit, keep what we can and stabilize then ship those we have to. Not only do you get the full spectrum of illnesses and injuries, you are also responsible for EVERYTHING, especially if you are on the night shift. I have done everything from delivering a baby then flying out a STEMI in less than an hour to caring for a hospice patient, gun shot wounds, MVCs, all sorts of chronic and acute illnesses to shoveling snow and standing between a hostile drug seeker and an ER doc. I do my own IV's, respiratory treatments, mix meds in the pharmacy, coordinate transfers for not just physically compromised, but psychiatric patients as well. My work girls are my family and hugs, shoulder rubs, and laughing and crying together are all a part of it. Critical access nursing will really hone your skills and give you skills you never though you would need.
Go go for it! Critical access is where it's at if you ask me :-)
