Using Legal and Ethical Decision-Making Model Wheeler & Bertram how would I advice the counselor? what is the ethical dilemma here

A counselor receives a phone call from a well-known internist in her area. The counselor is involved in a busy practice, specializes in treating eating disorders, and receives only occasional referrals from this physician. The physician wants the counselor to treat his 17-year-old daughter, who suffers with what he describes to be an eating disorder and perhaps some Borderline Personality Disorder traits.

The physician explains that he has been medicating her for about four months with Prozac and Klonopin, once he became aware of her eating disordered behavior. Because of his status as a well-known internist, he does not want to refer his daughter to a psychiatrist because he believes that he can handle the medication piece of her treatment. He will also pay for all treatment in cash, as he wants as few people and organizations to know about his daughter's issues.

Feeling somewhat uncomfortable with the medication management issue, the counselor indicates that she will have to call him back after looking at her schedule. The counselor then phones you for an informal consultation. The counselor expresses her concerns about working with a patient whose father is prescribing medication.
