I am so sorry to hear how you are feeling right now. Do not go to the worst case scenario. Most likely, they will just discuss with you what happened, and ask for your side of the story. Nurses are too valuable to terminate based on one patient complaint. The patient hit you! Therefore you had every right to remove yourself from a situation likely to escalate in which you could be further attacked and quite possibly seriously injured.

I am sure they just need to talk to you to get your side of the story. (I know I said that before, but it warrants repeating). There was an incident where you were physically attacked. They need to follow up with you to make sure that you are okay. They could face liability depending on your injuries, physically or emotionally. They need to know that you are okay to safeguard themselves from liability.

You will be okay in all of this. You handled the situation correctly!
