I can count two classes where one or more people were asked to disrobe in class.
The first time this happened, we all understood that this had multiple purposes. First it was to teach us how to be empathetic to the patients since we would be undressing them.
Second, we had to learn procedures the way they're supposed to be done.
The R.N. teacher let us know ahead of time what we would be doing.
The classmate I got paired me up with was trustworthy and I had no problems with her.
The second time I was in a class that required nudity, was a few years later in one of those schools that only cares about making money and not about the students.
The teacher did not tell us that someone would be asked to disrobe.
Instead it was, "Who wants to be the subject?" Since I did not know what I was getting into, I got on the table.
I was laying there in front of a class that had both men and woman while the lecture went on.
When they went to take my shirt off and required me to be exposed
I adamantly refused to cooperate. Another student had to take my place.
It's been several years but I remember being offended that they would put someone on the table in front of their classmates and expect them to have their shirt taken off without telling them first before they asked someone to volunteer.
I remember being treated as if I was terribly shallow and self-involved because I would not allow them to take advantage of me this way.
Was this my own misinterpretation, I'm not sure.
I do know I was so insulted by them talking about my "attitude" that I contacted my teachers later on only to find out they did not even make those comments on my grade report. Instead, it was the owner of this school who was already getting complaints.
I was so offended that I sent a letter to the state board who adamantly sided with the school and informed me that it was for the purpose of education.
I do think it makes a difference how this is handled and no one should be obligated to get exploited for educational purposes.
