Changed jobs-Grass not Greener

So, I took a weekender job at hospital B but still work at hospital A per diem. Hospital A had a weekender job but did not offer it to me/ did not exist until I took hospital B job. B is great but now is becoming somewhat dangerous and is in a state of flux. A filled the weekender job - damn. So I am stuck with B for the primary job. The problem with B is that the floor I am on did not have a manager and now is in debt - so they are cutting staff - dangerously cutting staff. Like mixing the acute side of the floor with the regular side of the floor for assignments. Someone with have 2 acutes and 3 regular patients. The acutes are q2hr vs and checks-on tele- may have drains that a reg floor cannot have- drips. The reg floor may be people up and walking but also may be total cares. There is a lot of people that are upset and leaving - but I have to stick it out because I just got there and left a place ( still per diem) because I thought A was getting a little crazy. A does not have the job I want, but I want to go back---but I can't because I want to go back to school and I just have to wait a bit longer for tuition reimbursment.
- So another thing about hosp B - some of the docs are really ignorant and talk down to me - which I give it right back but in a way that is professional- Also there is this one nurse that is completely nuts and is in charge- She notice that I did not give a flu shot before the pt left - but in my defense I found out about an hour before that the pt was suppose to go. So she stopped the transfer. The patient ended up having to sit in a wheelchair for a hour and a half before pharmacy sent up the shot. The patient was crying and was in pain from sitting so long- I could not give her any pain meds because I had just given her some not too long ago. ---- Also I had a pt getting blood and the infusion stopped- so this nurse tells me after she had gone into the room that the infusion had stopped and I needed to flush the line before the line clotted off ( thanks captn obvious). She just keeps doing these wacky things but she is still a real good resource- any advice?
