Some questions re: case management nursing

Hello ladies and gentleman...

I'm a pre-nursing student, just exploring the wide array of oppurutunities nursing presents to people. So, it seems the minimum level of education to get into case management nursing is a BSN. Correct? What is your role as a case manager? What is your typical day like? What are your hours? How many days a week? Any other information you would give to students about case management nursing?

Thank you!
