I have another article that gives my best advice to new operating room nurses. You may want to read that.
Most facilities require the RNs to circulate as well as scrub. There are still a few that employ only RNs; in these, it is easier to focus on the scrub nurse role.
Have you been in an operating room? It would be good to find a surgeon who will let you come and observe a few times. I mean a few days, not just a few surgeries.
I feel Alexander's Care of the Patient in Surgery is an excellent investment. I recommend it for all nurses new to an OR.
The only other thing I can think of at the moment is trying to get a job in the central sterile department. If you cannot get hired, try to volunteer. Central sterile is where all the surgical instruments are sterilized. Being there will help you to learn the instruments and their uses. The people in central sterile are an excellent resource for this.
