Yes, Julie, I am aware that some psychiatric symptoms can be caused by medical conditions.  Nurse Practitioners are given those rotations in their undergraduate programs.  That's why the Master's programs are able to be more focused.  Nurse Practitioners also consider all aspects of the patient, including co-morbidities, family issues and support, social issues and support. Is the training for Physicians more indepth?  I'm sure it is.  That's why we refer to them when needed.  If they are available and allow us to do so. I'm not sure why Physician do not take any courses in Policy and Politics.  We do to make us more able to affect legislation and advocate for our patients.
