May 20th at post conference Amanda challenged me in a disrespectful and unprofessional manner about not getting a lunch break on a day of early dismissal while I was trying to discuss some concerns I had in the clinical area with the class that day. She spoke loudly enough that she was easily overheard by unit staff who also noted her behavior and attitude. This behavior disrupted my post conference at which time I dismissed her and the class. Amanda violated the student policy of respect to faculty and professionalism as stated in the student handbook.Amanda has been informed that her behavior was inappropriate and in violation of student policy as stated in the student handbook.
