Public humiliation of students

I am a Nursing student from a prestigious College...which means I'm still in the process of learning. A senior consultant often uses embarrassing terms in front of the patients and families like "why are you asking doubts to them, they are student they don't know anything" or "Student Nurses are waste only" or "Do some work or get out" ... doesn't allow us to justify any of the questions that are being asked... when any tries to answer the consultant makes a ruckus telling students are talking back ... publicly humiliates in middles of ward which has around 100 people ... these public humiliation are so distressing to Students...Is there any law to protect us from getting humiliated in front of public ?
