Willie,
Funny thing is the young nurse that came in to do my IV start was a bit nervous and had a difficult time getting into the first vein she tried, so I suggested a second, more appropriate vein, using the proper anatomical location terms and the reason it would be easier to access.
She looked up surprised and asked, "You're not a doctor are you?". I laughed at that and said, "No way, I am much better than a doctor, I am a nurse like you" which made her laugh and relax, and the second attempt was flawless.
