Client abuse

I overheard something in class the other day while waiting for class to start that has been troubling me greatly. I'm sitting with my headphones on, (music very low so as not to disturb anyone and not so loud that I can not hear) and I overhear the two girls talking about working a shift at a facility that cares for mentally impaired patients. One of the girls is relating a story of feeding a 30s something woman that has some sort of degenerative neurological disorder. This client through the relation of her story was or is apparently a lesbian. The girl telling the story goes on to say that this client doesn't want to eat quite often. 

These were her words. "So she is not eating again, and I get this idea, right? I tell her that she should just imagine that its a pussy and go to town. And she totally does! it was hilarious." 

Shocking disbelief was my first reaction followed closely by disgust that this girl is going to be a nurse. A patient advocate for people that can't or won't advocate for themselves. How in the hell can someone that is going to take on that role, be actively abusing clients. I'm at a loss for what to do. My information is hearsay, she could have made it up to tell a "funny" story, and who would I even tell?

Anyway, I just felt the need to vent to someone other than my wife!
