Hello, I am a returning OR Nurse. I am 50 yrs old and waiting for my approval for a Preceptorship in a Hospital before I can process my enrollment at MCC Refresher course. I am excited and at the same time nervous going back to my favorite job. The Nursing school will help me brush on my Nursing skills, but my specialty is in the Operating room. I just want to know what books I need to read just to keep me updated before I am exposed to the OR. I know it's been 20 yrs since I step inside the OR, but the skills and knowledge are still there. I just want to make sure that I'm not making a lot of mistakes and at the same time I'm trying to make my transition easier. My school is requiring me to have 132 hrs of clinical exposure. Can you recommend a specific books to read? Also, how many weeks is the orientation period typically? Thanks.
