I guess I'm confused. Are you looking for an anatomical chart? Because there really is no "wrong" place to put a PIV as long as it's in a vein and patent. Arterial PIV's are a huge no-no, of course (once saw a tragic case where a pt lost an arm because people were putting meds into a line that had been inadvertently placed in an artery-- don't know HOW several shifts missed that one!).
Realize, too, that anatomical charts are just the "norm", not the rule. I cannot feel my own carotid pulse on my right side. I never thought anything of it until, for other reasons, I had a carotid ultrasound done. Turns out my R carotid is placed oddly, and thus cannot be palpated!
The best advice I got re. finding PIV sites was to simply practice feeling them on yourself, coworkers, etc. The wrist/ forearm below the thumb is a good spot. Usually there is also something on the ulnar forearm. A/C's are great for immediate access, but if a patient is a long-term person, they tend to go bad and if you're giving drugs that can cause tissue damage, it make take longer to recognize the damage. The patients we get from the ED always have A/C's, and we usually start another line in a different spot just because, while they're a nice large bore needle for the most part, they tend to go bad over more than a day or so. Hands are good for visual veins, but often will infiltrate, in my experience. I don't like starting IV's with only a visual approach, because sometimes something that looks good will be anything but. I also tend to avoid any body part that has a lot of movement, if I can, because the IV's can kink or get dislodged. But beggars can't be choosers, can they? ;-) Babies can get foot and scalp IV's. But, because of my setting (ICU), I tend to use forearms due to lack of movement and their 'staying power'. You can't see them for the most part, so you practice feeling. Veins feel a bit spongy. Tendons are harder. Just keep practicing! It'll come with time and you'll find your "guarantee" spots.
Hope that helps!
