PSA: if you are a vet student, it is very rude and it makes you look like a nincompoop, when you try to advise a veterinarian on how to do something... esp after you had failed at the task yourself.
I was beyond irritated when I had a student criticize everything from my choice of catheter size, choice of vessel, and taping technique... Along with her unsolicited commentary and assessment on everything that was going on (e.g. "Oh that vein doesn't look that bad, you should be able to use that one").
I was PERSON NUMBER 4 to try, and I was able to get it in a single attempt with my choice of catheter size (that the student thought was too big), in a mangled vessel. Clearly, this is not the easiest catheter placement when 2 seasoned tech and vet were unable to place it after the student. It was especially irritating when the student then gave me a condescending "good job," then proceeded to tell me how a different taping technique would be better and how she would feel more secure with it if I would add on another piece her way. This was also a student with less experience in tech skills than I had over a decade ago. Blergh.
