If a med student rotates with me with that attitude, I would make sure the dean of med school hear about this.
Seriously, too many people I have worked with basically ass-u-me that psychiatric issues are not "medically related". Hell, too many times I had to diagnose critically ill patients who were "medically cleared" to us. It just pisses me off. Not because we get extra work, but because you might put patients at risk with that attitude.
There are tons and tons of medical issues that would decompensate or contribute to a psychiatric issue and you simply just can't write off "medically clear" everytime a patient tells you that he sees demons and angels.
