Best wishes in your new position! I have been through a bunch of surveys, and, truthfully, although a bit nervous, not really afraid. I was not easily frightened because I knew my stuff! MSDS book? On the shelf behind the nurses' station! How to do 'x' -look in the procedure manual. Types of isolation? Policy manual!
But the best was - - I was being questioned about my patient who was on contact precautions with MRSA, and the surveyor had his chart on her lap. And she would lick her fingers and then turn the pages. Ewww! After a few times, I leaned in very close to her, and asked her to please stop doing this! The entourage behind us - the DON, my head nurse and supervisor, and others - collectively gasped. The surveyor looked at her hand, then looked at me and said that she just never thought about this habit. And that it was inappropriate! When she finished her perusal of the chart, and her questioning of me, she shook my hand and thanked me! My employers were not impressed with my 'forwardness', and let me know. The next day, I was in the cafeteria, and the DON approached me. She said that the surveyor couldn't stop talking about what I said and was glad that someone stopped her from doing that! BTW, our unit got a perfect score, and I was the only one she spoke to!
I remained unafraid of surveyors, no matter when or where they appeared, because they are only humans with clipboards! Or computers, these days!
Try to put the individual nurses at ease, most are intimidated by your very presence!
Again, best wishes!
