"Carelessness"

Recently, I was trying to call my parent at Opal Bankstown but they didn't answer their phone. I then called my sibling who told me that our parent was trying to reach the emergency buzzer and had fallen off the bed and taken to the hospital.  

In my opinion, due to the staff's carelessness of putting the buzzer out of my parent's reach, they fell off the bed and hit some kind of furniture and got hurt on the forehead and one of their eye is coated with blood and face is swollen.  

My parent can't walk or get off the bed, the nurse has to use the lift to lift them for a shower or go to the toilet/bathroom. The nurse, in my opinion, gave a false statement that my parent was walking to the bathroom and lost balance.

More recently, I was calling my parent but the phone was out of their reach. When I called for the 2nd time, after a while a nurse, I believe, answered. I asked if I could talk to my parent, so the nurse gave the phone to them. I asked my parent why the phone was ringing and ringing and they said the phone was far from them and it was out of their reach. I said, how come a nurse answered and my parent said they were passing by the room and heard the phone ringing and came in the room and answered.

I am living in the USA and my parent is in Opal Bankstown and my older sibling looking after them with the care of Opal care Bankstown. A couple of months ago, I visited the facilities with my siblings. We all noticed that some of the employees, especially the nurses, in our opinion, were not very friendly with the patients in their care. We also noticed some times when the emergency alarm from the rooms are on (needing help), the attendants attend very late, by then I feel something very serious can happen.
