On the First Day of Clinical Rotation on an Inpatient

On the first day of clinical rotation on an inpatient psychiatric unit, nursing student A complains of nausea, sweaty palms, and stomach butterflies. Nursing student B attempts to console student A by saying, "You just can't take anything these clients say personally; don't listen to a word they say."
Having observed this exchange, the nursing instructor should be most concerned about:

A) Student B's lack of appropriate fear towards this potentially dangerous environment.
B) Student B's perception that listening to the client is unnecessary.
C) Student A's fear about the psychiatric setting.
D) Student A's symptoms of an impending panic attack.
