Pre-employment evaluations/tests

I am moving soon and looking at jobs in my new area. I've come across performance evaluations and medication exams (most notably at the UC Health System in California). I'm curious what kind of things are actually tested when you apply to this kind of staff nursing job. I haven't heard of these tests in my area or most others.
There are ALWAYS medication tests. Count on it.Not sure what you mean by performance evaluations? You can't be evaluated by performance since you haven't performed yet?
