I've been a phleb for 20 years now; just graduated from nursing school!!
Almost everyone has a decent vein in their wrist-turn their hand so the thumb is on top and the pinkie finger is on the bottom (their hand will be "sideways"), and use a hot pack or wrap hand/wrist in a hot towel. These veins must be anchored properly or they will move away from the needle. Also, I don't know what your facility's policy is (some do not allow this), but in extreme cases I will draw from the inside wrist-palm side- after warming up the area with a hot pack. I use the smallest gauge needle I can get away with as this is a tender spot for the pt. Don't be afrain to check for surface veins on the upper arm or on the back of the upper arm; most elders have veins in some strange places you can access. Take your time whenever you can-better to take your time looking for decent access than to stick people numerous times.
Good luck and remember-no one gets everyone-at times we all have a difficult day trying to get blood from these patients no matter how much experience we have!
Hang in there:spin:
