While doing volunteer work at a mental hospital, Mary is put on a ward for adults with severe mental disorders. One patient remains in the same position for hours at a time and never talks. The doctors tell Mary this patient suffers from

A) depersonalization disorder.
B) catatonic schizophrenia.
C) disorganized schizophrenia.
D) paranoid schizophrenia

Answer: B
Rationale: Symptoms of catatonic schizophrenia include episodes in which a person remains mute and immobile—sometimes in bizarre positions—for extended periods. Individuals may also exhibit repetitive, purposeless movements. While some of these symptoms can occur with other types of schizophrenia, motor symptoms are most closely associated catatonic schizophrenia.
