Was I too pushy?

Hi. My 74 year old father is in a nursing home right now for some physical therapy. He has parkinsons disease and also has NPH and has a VP Shunt on the right side of his head. Last wednesday morning (around 2am) he got out of bed and went into the bathroom and fell and hit the sink.. He had a huge goose egg above his right eye.. (I don't know when the night staff realized he fell) The day shift nurse called me at 9am that wednesday morning and told me my dad had fell during the night and had a pretty bad bump on his head.. I asked if he seemed like he was ok and she said yes.. Then I asked if he could have a CT scan to check the VP shunt to make sure it was ok.. She told me that the doctor said it didn't need to be check and then proceeded to tell me that insurance wouldn't cover the CT scan.. (Even though in the past when he has fell at home I take him to the er and they always do a ct scan.) To make a long story short yesterday the nurse called me and told me my dad wasn't doing very well and said he was having a hard time walking.. I became very upset and went right to the nursing home to see him and on my way in the DON stopped me and asked if anyone had called me about my dad.. I asked her if they were going to call the doctor and let him know about him and she told me that there was nothing to do.. I told her that if they didn't do something that I was going to take him out myself and take him to the hospital and have his neurologist check him out and also told her that the shunt in his head should have been checked to make sure that it was ok a week ago when he fell.. She just looked at me and rolled her eyes and walked off... (I'm not a doctor and I don't know if this even has anything to do with him falling but, its just very upsetting.) I feel kind of bad today but, I feel that if I wouldn't have said anything then who knows what could happen..
