Ok, first off, take a deep breath and don't panic. Speaking as the person who does this sort of thing for a living, here is some advice:
If you have malpractice insurance, call them. They won't do anything because there is no claim against you, and therefore your coverage will not be triggered, but go ahead and call them. Search for my other posts under my name in which I discuss at length the issues of coverage triggers, that your own coverage is excess coverage, how you are covered through your employer, the responsibility of the employer for your actions, etc. One Healthcare Risk Manager's View Of Individual Nursing Malpractice Insurance
Next, read this post: https://allnurses.com/ob-gyn-nursing...t-1045407.html
in which I discuss some general principles of lawsuits, giving a deposition, etc.
Your best source of information is the attorney representing the LTC who is also representing you as an employee. Based only on the event description given, I would not be worried regarding your future in nursing or actions against your license. It sounds as if the LPN is most proximately responsible for the event.
Post here or send me a PM if you have followup questions after reading my linked posts above. The posts do answer many of your questions, so they are worth your time to read.
