Is it right 2 humiliate new trainees in front of customers???

i now got a full-time job at a gyne clinic as a trainee nurse. YAAAA!!!! but the sucky part is that the nurse in charge like 2 embarrass mi in of patient e.g. one time i was talking on the phone with a difficult patient. At that time i was still new so i dun really how 2 handle that patient, it took mi about 5-10 mins until i can put the phone down. Then the nurse in charge just suddenly call mi Blur Blur in front of the patient sitting next 2 mi. After that my face went damn freaking red.
