They can do whatever they want and whatever you let them. If you have a union this may be the time to get them involved. 

I’m afraid I won’t be able to offer you much. I work in a large oncology clinic that is physically in the medical center and our patients are super sick. We also are an all RN clinic with PCA support. I will say one thing you want to find out is how often you will be expected to stay late. We routinely put in anywhere from 3-10 hours of overtime in per week due to clinics running late and admit holds. You’ll want to know about patient phone calls as well. Are you given a specific time to do them or are you expected to fit them in around your other duties which can be very difficult. We average around 700 but can get up to 1000+ calls a day. Yes, that’s per day. We are supposed to have 7 nurses assigned to phone triage but that doesn’t happen often. Will you be doing PAs as well as med refills? What EMR are they using? Clerical support? Medical records? Case manager? The support staff makes all the difference. If you have to be everything to everyone it can become an overwhelming grind. Whose responsibility is it to prep for clinic? That’s a huge job depending on your patient load. The good news is at 2 days per week you’ll likely escape a lot of the heavy responsibility but still…

Yes that would constitute abandonment and you would likely end up before the BON or worse. Find another job.

A tracheostomy is the actual opening thru the neck into the trachea creating an alternative airway. It may or may not have a plastic tube in it. A trach collar is a device that goes over the tracheostomy and provides humidification and supplemental O2 if needed.

ETA: some people refer to the ties that secure the trach tube in place a "collar" as well. That isn't incorrect but I've most commonly heard them referred to as "trach ties".

You still haven't "done drugs"! Ibuprofen is a legal, over the counter medication and they don't test for it. Stop worrying.
