The nurse is performing the admission assessment for a client with schizophrenia in an acute care inpatient facility. The nurse should identify which observed behavior is characteristic of schizophrenia?

A. Responds with illogical answers to questions: Schizophrenia is characterized by disturbances in thought processes, including disorganized thinking and loose associations. Illogical or tangential responses reflect impaired reality testing and disrupted cognitive organization. These thought disorders are considered core positive symptoms and often manifest as incoherent or non–goal-directed speech during assessment. B. Describes times of depression followed by feelings of euphoria: Alternating episodes of depression and euphoria are characteristic of mood disorders, particularly bipolar disorder. Bipolar disorder involves cyclical mood disturbances rather than primary disturbances in thought form. Sustained mood cycling is not a defining feature. C. Exhibits compulsive, ritualistic behaviors: Compulsive, repetitive behaviors performed to reduce anxiety are hallmark features of obsessive-compulsive disorder. These behaviors are typically driven by intrusive, distressing thoughts and are recognized by the individual as excessive. Schizophrenia primarily involves psychosis and disorganized thinking. D. Admits to frequently thinking about committing suicide: Suicidal ideation can occur in several psychiatric disorders, including major depressive disorder and schizophrenia. While individuals with schizophrenia do have an elevated risk for suicide, suicidal thoughts alone are not diagnostic or characteristic of the disorder’s core symptom profile.
