My question is- is there a transitional job that anyone would recommend? Like risk management or case management? Any other certifications that would make me a more appealing candidate?
Jobs like risk manager and case manager -- generally do not lead to unit manager jobs because they are a totally different type of "manager." You seem to be wanting a career in Nursing Administration -- a type of management that involves managing personnel, supplies, budgets, etc. Risk Managers and Case Managers don't do those kinds of things.
You should look to be a Charge Nurse or Shift Coordinator, etc. -- something that gives you experience on the operations side of things -- giving you responsibility for managing the work of the other people and being accountable for what they do (and what happens) when you are in Charge.
You can get other good experience by being involved in Shared Governance or as a committee member on a project that plans, implements, and evaluates a change in practice on a clinical unit. Such experience teaches you about how to make change, work with others on a team, etc. People who lead such projects are seen as leaders -- and they are more likely to be selected for jobs such as Assistant Manager, etc.
