Va hospital Orientation process and medication test

I start the at the VA on monday on the dialysis unit. Monday is my first day of new employee orientation. I just want to know how orientation goes. I know I have to take a medication test but do they review the material in orientation. If I dont pass the test does that mean I can't wotk there? I'm a little nervous about the te4st just because they gave me a sheet like a week ago with 40 Rx on it and I have to know side effects/adverse reactions, nursing implications, and teaching. I think i'll be ok with the math but can anyone give me some insight please. Thanks
