Being new myself, you dont want to cause waves n what not. But unfortunately, you're going to have to write up th CNA's for leaving the floor for as long as they do, remind them of their job. You could say their leaving the floor for 90+ minutes is abandonment resulting in neglect. And if thats the case then they need to be turned into the state department. Same as the nurses who dont do precribed treatments. Ive had some similar cases myself. CNA's being rude and not doing what is asked. I was an aide for 8yrs before becoming a nurse. I know their job and mine. We all work hard during our day even if it doesnt appear we do. There are lots of things on our shoulders and things going on that they dont see Keep your chin up and care for you patients as best you can
