Ever had a doc yell at you? (OK, yell is not true, but he did raise his voice).
I was in a room with a patient, answering their call light when doc came in. He came up to me outside and was asking me (loudly) why I wasn't wearing gloves and gown. Patient was on isolation but I didn't know that. Then he reported me to the charge nurse and I got into trouble. It was my first time on that ward, I don't think I will go back.
I just said "Thanks for letting me know" and tried to ignore him.
