MAs - PLEASE. LISTEN TO YOUR PATIENT.
There was one very arrogant CCMA I had when I was getting bloodwork. I could tell she was a little green and very young, so I let her pin-cushion me a little bit for practice. No harm, I'm 20 years old myself and premed. Also young. I'm also an EMT and probably don't understand how hard medical assisting can be. I let my students in the ER do it all the time. It's one of the only ways to get better - practice.
She ended up sticking me 12 times before I said "hey - I'm an EMT in the ER and start IVs all the time for emergent patients dealing with dehydration and stuff and I think I'd pick this vein. it's bouncy, big enough to take a 14 gauge no problem."
Then she said "y'all the ER and only see the patient for 2 mins and send them away, y'all just some glorified send-awayers. i was in the ICU in college. that's why we have beds and y'all have stretchers"
I'm sorry, what the fuck? Okay. Just pick the vein I suggested or one you can actually see because it's starting to get painful.
After attempt 20, she picked the vein I suggested and finally got blood.
