I'm headed back into travel nursing and have the same question. Before my last assignment, I took no less than 32 tests to start with one particular agency; they ranged from med-surg to maths to the required JCAHO required fire-safety and OSHA tests. Needless to say there was plenty of freaking out going on about having to take Med/Surg exams after ten years in cardiothoracics. I hadn't thought about gallbladders in years! I've done a good bit of studying by simply "googling" PDDS study guides and such. My question is, does anyone know if these exams are required for every single travel assignment? i know the JCAHO ones are, but the rest as well? I'd think the exam results would be on file with the company that I just traveled with not three months ago?
