I think that every one of us was nervous when we had to perform our first invasive procedure! I was lucky, my first injection was insulin into a patient that was so used to sticking herself, that she even gave ME a pep talk while i was doing it, i was nervous and she giggled at me and assured me that it didnt hurt and that i would "be a pro" soon
i personally think that if you are not nervous the first couple times, then there is something wrong.
I got my first 5 IVs on the first stick, but then on the 6th, froze up, probably because i had become too comfortable with doing it. a little bit of nervousness just makes you cautious, not inept
good luck, you will do fine!
