Felt overexposed at nurse. Advice?

Hey guys! I don’t know where else to post, but here goes:

I just came back from a hospital where I was screening for a clinical trial. I was wearing a leotard and had to through the ECG procedure. The nurse told me that the stretchy fabric made the situation even worse and that she’d have to pull it down in order to put the stickers on my chest and below my breast. Fair enough—-wrong choice of clothing. Sometimes stickers are not placed under my breast and sometimes they are, but I figure , “ok no problem”. The issue I have is even after placing the stickers under my breast, she did not pull up the fabric to prevent my breasts(& nipples) from being exposed. She was also training another woman , and these two kept on going in and out of the room more than 10 times. Yes I counted & I spoke up to the nurse in training about it. The computers were making beeping noises and having technical difficulties… this is after lying down for about more than 20-25 minutes… So I decided to pull up my top to cover my breasts because I was just getting sick of her walking in and out and leaving the door a quarter way open.

Then she uttered to other nurse, “I’m gonna have to call some of the guys to fix the situation with the computer”. She didn’t even look my way but scurried out the door & returned a brief moment. I was constantly told to not move whatsoever but of course she did not want to put some sort of blanket or anything else to cover on my bare chest . Luckily, I pulled up my top before she & the guys walked in to help her with the computer situation.I just don’t understand. How could she lack such self-awareness on this issue. Hate that I felt so bare in such a space where males were walking the halls and even entering the examination room. How would you all handle this issue?
