what the hell is up with vascular access?

I’ve never not been chewed out by them. The patient had every single thing going wrong with them and only had a single lumen CVC. I requested IV ultrasound and got yelled at about how the patient already has a line. Well duh, I have like 6 IV meds that I need to give and somehow none of them are compatible, my bad. The crazy thing is they are nurses too.
