Thanks for everyone's feedback! I figured it was best to go for a preceptorship in the area I'm most interested in. I guess my main concern is I'm not positively sure where I want to work. I'm at that entering-senior-year crossroad, where I want to work in several different critical care environments, and not sure which path to choose! When nurses enter the ER, what is their background/experience? Do nurses from the ICU float to the ER and vice versa? How exactly is the ER critical care different from ICU critical care (stress wise, knowledge wise, etc.)? What makes a good ER nurse? Thank you again for your much needed wisdom!
