this may seem like an incredibly stupid question :imbar so please .... no rolling of the eyes.. :uhoh21: I am a pre-nursing student and am looking into what it takes to become a CRNA (like so many other people lol). I figure if you aim high you have nowhere to go but up, huh!?! I am concerned about the one or two years of ICU experience. What is considered ICU. I have seen SICU, MICU, PICU, CCU, NICU, Etc. Which is the one they are looking for? what are the differences? What is the difference between level I, II, and III? If anyone can enlighten me I would so much appreciate it. Thanks!
