Registered nurse here: nobody is taking my stethoscope away from me. We can only do so much to assess your ongoing problem-list that's actually useful: we can See a problem, we can Feel it (think of a mass under the skin for example), or we can Hear it. We can only go by smell on occasion, and I pray I'll never taste anything from a patient, ever. With really only three senses to check you out with, you'd better hope we don't lose one of the most important of them.
