Apsychologist, whose primary focus is sleep behaviors, gives an acquaintance advice regarding psychiatric medication. the psychologist is considered an expert in his field. why is this behavior unethical?

This behavior is unethical because the psychologist is not even qualified to give psychiatric advice. Even if she is focused in sleeping behaviors and the patient is in need of psychiatric advice, it is still unethical for it does not cover the psychologist's focus in regards of his or her work that is taking on. Giving psychiatric advices does not cover her focus or is not in lined with her work.
