Answer to Question 1

ANS: C
Atypical antipsychotics have been noted to block oral dyskinesia and improve tardive dyski-nesia as well as improve both positive and negative symptoms of schizophrenia. Pseudopar-kinsonism and dystonic reactions are associated with typical antipsychotic medication. Anti-cholinergic symptoms are not intense with the use of atypical antipsychotic medication.

Answer to Question 2

ANS: A
The MRI will reveal structural changes in the brain that might be responsible for symptoms of psychosis (e.g., abscess, tumor). Psychologic testing may be performed but will be less defin-itive in ruling out organic pathology. Immunologic studies are not indicated. The DST is re-lated to depression.
