I agree! A year or so back I had to have a surgical biopsy done for breast cancer.
Well, the nursing staff kept looking at me in a weird way, like I had offended them or something, yet I had done nothing at all except check in!
The nurse who set my IV made 3 tries before getting it right, and she seemed to be real cool with that. THEN she went up behind me to the IV bag, and next thing I know I yelp right out in sudden pain. She cheerfully said that she “had to clear the line” by squeezing the bag. Now, I have had many dozens of IVs and not ever has any nurse done something like that. Anyway, I didn’t say anything about it, and a few minutes later that bitch did it again! After I got home I noticed that 2 of the IV “tries” were not even close to the vein. Not close at all.
I am a physician. I know that sometimes it is difficult to get the needle into the vein. I have had my own veins missed, and I have missed some myself on the first--or maybe even the second--try. As a general rule, the person who has been finding veins for a long time is the best at doing it right on the first try. It might be someone who has been trained only to do that.
I have never known anyone to assault or inflict pain on a patient intentionally. If I did, I would not tolerate it under any circumstances.
I have fired only two people, a man and a woman, both for faking lab tests in separate incidents. As soon as I proved that they had done this, I fired them on the spot.
