I am wondering since I have to use a manager, if I should use my managers name, and then just put the number of my hospitals HR.
If the prospective employer is asking (requiring) two references from managers, any effort you make to cleverly circumvent their request (like giving them the contact info for HR instead of for your previous manager) is likely to be considered dishonesty sufficient to get you dropped from consideration for the position. At best, they will keep asking to be transferred until they actually get to your former manager and are able to talk with that person. At worst, your application will go in the circular file.
Your situation is what it is. You need to be prepared to address the termination in future interviews and be able to talk about what happened, and what you've learned from it and steps you've taken to ensure you won't find yourself in the same situation again, in a nondefensive way without badmouthing your previous employer.
Your HR person is incorrect. It is likely your previous employer's policy
that HR not release any information beyond hire and separation dates (and, usually, eligibility for rehire), but, legally, a former employer can say anything, or as much as, they want to about a former employer as long as the information is factually correct.
The good news is that you're not the first nurse to get terminated from a position, and most are able to continue on with their careers. Best wishes for your journey!
