Tarasoff v. Regents of University of California held that:

A) A psychotherapist had a duty to warn a person that his patient was making threats to harm a third person.
B) The hospital had a duty to require that patients be examined by members of the hospital staff who were skilled in the treatment required.
C) The hospital did not apply its own credentialing rules and, therefore, did not follow its own standard of care in determining the qualifications of physicians practicing at the facility.
D) When a physician withdraws from the contractual relationship with a patient, he must provide the patient with reasonable notice to obtain a new physician or alternative treatment.
