I have a story on that one.
Not a nurse but an ultrasound tech had to do ultrasound of my private area where my wife worked. The Ultrasound tech didn't know me from Adam until the X-Ray tech told her who I was. She was trying to talk about politics, music anything to make it less awkward. My wife asked how it went when I came home and told her about X-Ray tech big mouth and she just busted out laughing.
