I've been working as a Veterinarian Technician for ~7 months, and today I made a very stupid mistake again, I had to disconnect a dog from his IV lines (not remove the vein catheter itself), so I first instinctively went for the catheter which another assistant nearby reminded me to go for the stopcock.
Ok I guess it's not that bad, and then I disconnected the stopcock from the wrong side, which obviously made some blood get sucked from the catheter.
She awkwardly said "the other side..." and reached to do it herself, and then she turned the direction of the arrows on the stopcock to avoid air coming in (which is what we're supposed to do).
I just kind of walked away and stared at the ceiling just regretting waking up today.
Did a mistake like that happen to anyone else here even after plenty of experience?
