Protocol for Admissions offers (Clinical)

[clinical_hopeful_2017]

Hi all, I am wondering if anyone could potentially clarify the proper protocol to follow when offered  admission to a Clinical Psych PhD program after interviewing?

I am just curious about the idea of "holding" offers, as I've been told that you shouldn't have more than 1 offer at a time? Should you let 1 school know like 'hey I'm strongly considering you but waiting to hear back from other schools'? If given an offer to your second choice, should you email your first choice to let them know that you have an offer from X University but admission into your University would 'change my mind'?

I apologize if my examples are confusing, I just have heard so many mixed pieces of advice regarding this. 

Thank you for your input!
