Mary Was Recently Admitted to the Psychiatric Ward of a Hospital.She

Mary was recently admitted to the psychiatric ward of a hospital.She does not seem to talk,except for mumbling a few incoherent phrases every few hours.When asked why she thought she was brought to the hospital,Mary just shrugged her shoulders,not seeming to understand the question.What is the best way for hospital staff to assess Mary's psychological state,and why?

A) They should use a projective test, such as the Rorshach, because the Rorshach does not require Mary to talk.
B) They should use an objective test, such as the Minnesota Multiphasic Personality Inventory, because it can be completed by someone other than Mary.
C) They should perform a mental status exam, because it is based primarily on behavioral observation.
D) They should use the Thematic Apperception Test, because it is designed to be used with severely disturbed patients.
