I have been a registered nurse for 6 years, mostly working in post surgical units. I was interested in the OR and landed a sponsorship. The theory part is finished and I will start clinial next week. Im a little anxious to say the least... I am told that there will be yelling, 'everyone in the OR is crazy', you will suffer, etc. Can I hear anything positive? Can anyone give me tips on making it in the OR? My anxiety is through the roof. I am preparing for the worst. I can be a little timid at first and I don't have an extrovert personality.
