PCT Question

I don't know if this is the correct sub for this question, so feel free to redirect me!

I am interested in becoming a PCT and am curious about what the hospital setting is like. For those who work in a hospital, what is it you do? What floor would you recommend to someone just starting out?

Also, stupid question but I am curious: If you work the night shift and have to make your rounds, do you take their vitals while they are sleeping or do you have to wake them up?
