According to this article, it is mostly in LTC where med aides are used and apparently abused by being asked to perform tasks that are beyond the scope of their practice.
Is this what is really going on? Maybe we have to be as careful with our support staff's ethics as with our own. I would like to imagine that we all would refuse when asked to perform outside of our permitted scope, and that we would be annoyed if pressured to do so.
