I'm going to have to agree with what's already been said. As an ED nurse, we truly get a bad rap for literally everything (including what's not in our control) and while it can definitely be frustrating for patients and their families sometimes you don't get the care you want. Sometimes I don't have time to sit down and discuss things, much less pee. What were her symptoms? What is the recent medical history you referenced? Because as an ED nurse, what you (general you) think is relevant often isn't. I think the take away here is yes, it is awful to wait in the ED for 8 hours but that's just reality sometimes. It sucks but that's what it is. Also, thankfully, she wasn't having a stroke so I am not sure why you seem to be upset about not getting an incredibly expensive stroke work up? Unless I am misinterpreting your post. You never want to be the one we're rushing back. Ever.
I have no idea what went down during your mom's stay. I know that at any of the five EDs I currently work as float pool, there is no way she would not have had an assessment by someone, much less not having separate ones by the MD and the RN. If that's true, that is alarming. Now about not getting neuro checks, there are many different ways to assess neuro function and it doesn't sound like your mother warranted a NIHSS or something similar. Also, it does not sound like you were present for this so you are hearing everything second-hand and sometimes things are lost in translation.
Also also, our TPA timeline is 4.5 hours. It's definitely regional on the window.
