Greys Anatomy does it only have one theatre nurse?

I read she is a real theatre nurse and advised them on how things are done. Don't know if it's true.

I love Greys - especially in its hay day. I still watch it as I invested so much time on it, but it’s way past its prime. Yes. The nurse is BokHee. She never speaks but has been in nearly every episode, including being a silent wedding guest. Unlike ER, the nurses are never part of the story line unless they are having it away with a doctor in the clinical stores 😂 You never see them again. The only time they speak is to say ‘yes Doctor, right away’
