Tunable diaphragm

I was given a master classic II with a tunable diaphragm for nursing school. I just got my equipment list from school and it says I need a bell and diaphragm. Will the steth I have work, or do they want me to get one that I'll have to turn over for each feature?

Yep, that'll work just fine. This might help you to understand how it works.
