Turns their back on the sterile field momentarily to retrieve additional supplies.Which action by the nursing student is incorrect in maintaining sterile technique?

Susan thinks she is having a heart attack.  Her heart is racing, she is sweating, breathing heavily, and is afraid she is going to die.  When she went to the Emergency Room, the physician told her she was not having a heart attack and referred Susan to a psychologist.
