First off a nurse is not allowed to grab you or touch you. If they do so you can report them to the College of Nurses in your Province,
which I believe is NS. Also they had no right to ask you to leave in this situation as you fully have a right to be with your daughter during such an invasive procedure. You can be with her for most procedures that are not life threatening, where you may be in the way of the docs and nurses doing their work.
There was also no need for a catheter for this procedure as there are bags which are much less invasive. I would have been a wee bit perturbed over the entire incident.

I agree with it being not nessicry to do a catheter.. That;s a really aggressive and intrusive procedure.. Unless your daughter wasn't urinating at all or it was a absolute emergency there was no need for it. Just wait for the pee to come. I think I'd bring this up with the hospitl.
