How do I do that

I am a CNA and I was working a Nursing Home but my D.O.N called me up there and I went up there her and the H.R. Lady told me that they got complaints from employees saying that I don't answer call lights,i double brief the residents,and I be sleeping on the job and that they will get back with me after they do an investigation and talk to other staff members I am just wondering how will that take or does that mean I am actually fired and that is something they are saying to cover themselves I told them both that all that was lies which is because I am basically the only one on that hall that do rounds and answer call lights and I only get on my phone when I am through doing my rounds and answering lights I only go to sleep when I take my break and that the other aids only do 2 rounds one at 12 and one at 4 but I do mines every 2hrs I wish I can talk to someone who knows more about things like this that happens and tell me what I should do
