Sometimes I do. I see new grad friends who are "cautiously" starting on ortho floors or in med surg, and shaking their head at the ICU, and I can sometimes doubt myself. I always tend to bite off more than I can chew and I wonder sometimes if I overestimated my abilities.
But so far, I have been blessed with a 6 month orientation, a great fellowship where I"m receiving additional education, good preceptors, a patient staff, and a smaller ICU where I can take my time and learn and things aren't as nutty as a larger local hospital. I'm learning a TON and never bored. I can concentrate more on less patients and really think about things. Our unit is also nice and spread out, and I can work in relative peace and quiet, so I like that. Some days I feel it's too much and I do get overwhelmed . .. bu I just make it through the day the best I can, go home, and try to enjoy life. Every day in there builds knowledge for me.
I think that I would have been seriously burnt out physically from med surg, so I'm glad I started where I did. I feel if it gets bad, I'll be able to step down easily and be competent.
I think nursing is hard wherever you go-- there are tough aspects of every area. Critical care just requires a lot of extra education, so I like that.
I don't know .. I"ve been off for a couple of days, so I'm talking calmly and ationally now!!

Wait until I get back on and off from a recent shift!
I think one thing that has also helped my own situation is a change in management. We have two new floor managers who are trying hard to make it a positive atmosphere and effect change. They've been great to me so far ...but I guess it could get worse, and probalby will on some days.
LOTS of extra studying, that is for sure. You feel like you're still in school going into ICU.
