My assumption would be that the training would put a huge weight on precisely that.
I really don't think they'd spend all that time just learning how to mechanically draw blood and not have entire courses and exams on patient safety, record keeping etc.
Part of the challenge of social media is that it leads you to interact with many more people than you ever could in normal life.
While the vast majority of people are delightful, there are significant numbers of people with whom I wouldn't want to interact, either face-to-face or online.
One thing I should get better at is avoiding engagement with those people online who I wouldn't benefit from interacting with.
I don't talk to the crazy person ranting on the street, why would I do it online?
