For nurses about insertting IV's and giving Shots?

I have been working as a caregiver for roughly 2 years now and love it. I feel very good when i leave work and i have always had a sense of urgency to help others in need, especially elderly. I am about to put myself on the waitlist at a few schools for the RN nursing program as i feel nursing could be a very rewarding career for me. I know that caregiving and RN nursing are totally different, caregiving is just a small step, the first step into RN nursing. I’m still having doubts about it because i am not so into the whole drawing blood, giving shots and insertting IV’s part of it.

Firstly is there jobs out there where RN’s do not do so much of that? and if so what is the specialty for them called and where would they work?

Secondly, are there any nurses out there that started out just like me and were unsettled about the whole shots, IV’s and drawing blood part of it? did you get used to it or was it something that didn’t bother you in the first place?

i would appreciate any kind of input on this, as i feel it is a big dilemma and i think about it everyday and would like to know how other nurses started out knowing whether it was or was not the career for them?
