Great advice here. As an emergency room nurse, and for you a soon to be nurse, look at everyone as a first time client, regardless of your personal feelings. Two things you always do with a chest pain patient, hook them up to a monitor, listen to their lung sounds. Draw blood. I don't know what your policy is at your hospital, I have worked where techs could draw blood and where they can't. If you can, say to the Doc. look this patient is really complaining of severe chest pain, yadda yadda can I go ahead and get some blood?? He/She will probably say sure and get a portable EKG as well.
As a tech there is no reason why you cannot hook the patient up to a monitor. This is a judgement that you can make that you don't need a nurse to tell you to do. That is not a crime, if the nurse says anything to you say we need a baseline or it is protocol. If he/she gives you too much grief get another nurse or your charge nurse and tell them your concerns.
I don't think that you will have any worries here!!! But, I don't care if you are a nurse or an EMT or a Doctor or the janitor, if you don't feel that it is right go with what you would do. Worst case scenario for hooking the patient up to the monitor is vitals are stable and there is a normal sinus rhythym on the monitor. A nice baseline that I would want to see.
This nurse sounds dangerous, stay away from her as much as you can. Question her, and if you have a bad feeling get another nurse that you trust and would do an action any prudent nurse would do.
I appreciate all the help I get from a good PCT, don't be afraid to question a nurse or a physcian, I know sometimes that is easier said then done. We are all here for the goal of one thing and that is to take care of and advocate for our patients. All of the ER team members are there for this purpose.
Hang in there, and document things closely when you work with her or are assigned to her team. As mentioned above, watch for her to say I told the tech to do that. Keep a little note book in your pocket just for writing down the tasks she does or does not delegate to you. I am glad that you told someone your concerns if your manager doesn't do something about it, and you continue to see non-prudent judgement, go higher than your manager, or go to QA.
Hang in there!
