You need to get an admin to edit this post for you. Besides the nursing home's name, you also put the DON's name. That combined with your user name and the specific details of your post is risky. Plus you even have the exact time of the incident. As of right now, your post has had almost 300 views.
One of the best things about the internet is anonymity :-) Don't giveaway that precious gift.
You're going to have to wait and see what happens at work. In the meantime to be safe, I would start getting your rÃ©sumÃ© together and applying elsewhere.
It's probably not a good idea to use your cell phone at work even if you are all caught up with everything. Your coworkers, the visitors/family members, and the residents don't know you are "done." All they see is you sitting there on your phone. Plus there is always something to do at work, especially in a nursing home. Best of luck.
