The way I see it, you can risk staying and help rebuild, or you can find a safer place to practice. Only you can decide.
I have refused to take charge unless I had what I needed to do so safely. They won't like to hear it but it makes a point.
Something you might ask for that will really help YOU is a monitor tech...many facilities cross train their secretaries or CNA's to read monitors. Who is watching monitors while you are out on the floor with a code or helping out the staff? This is a huge lawsuit for the facility...just waiting to happen. They are taking a real chance here, IMO, and yes if something goes wrong they can take a nurse down with them too if they choose.
A tele unit in my area had no desk charge or techs at the desk and the nurses were supposed to be sharing tele responsibility. Well, someone ignored a flat line, thinking the monitor was off. The flat line was was asystole. Alarms were off cuz the nurses couldn't keep up with them. Now this place hired monitor techs after this incident, and settled the lawsuit, I heard. And the primary nurse was fired over the incident.
Someone has to watch monitors at all times AND be responsible for knowing what they're seeing. Anything else is a good case for facility negligence, IMO.
Best wishes...look out for your license. If your little voice tells you this is unsafe, it probably is.
