I think a big part of success on the CCRN exam is the experience level and maybe even the type of ICU in which you work. I used to work in a 28 bed Surgical/Cardiac/Trauma ICU and we would get a little bit of everything. Trauma's, Brain injuries, CABG's, MI's, GI Bleeds. So, I got very familiar with Swan Ganz catheters, Ventric's, Ventilators, etc.
The unit that I work in now is very small and the pt's would be on a tele floor at a larger facility. In this new unit, nurses aren't even allowed to wedge a Swan. Just found out today that we're not allowed to pull art lines or central lines either.

Oh well. Let the House Officer do it! One less thing for me to do!
On my exam yesterday I had a LOT of questions relating to Swan readings and their applications to the clinical condition of the patient. A LOT!!
I have never even SEEN the AACN Core Curriculum. Maybe I'd purchase it if it didn't cost like $100
