Which of the following represents a good sterile technique?
A. When using a sterile setup, avoid bending and reaching over it
B. Remove sterile forceps from their container and tap them on the edge so all the solution will fall off
C. Any sterile supplies added to a sterile tray, such as cotton balls, should be returned to their containers if not used, as such waste is inefficient and costly
