A nurse is performing an admission assessment for a client who has schizophrenia. Which of the following findings should the nurse identify as a negative symptom?

A: Echopraxia, the involuntary imitation of another person’s movements, is considered a positive symptom of schizophrenia, reflecting an excess or distortion of normal functions. B: Flat affect, characterized by a lack of emotional expression, is a negative symptom of schizophrenia. Negative symptoms involve a decrease or loss of normal functions, such as emotional expression, motivation, and social engagement. C: Somatic delusions, which involve false beliefs about bodily functions or sensations, are positive symptoms of schizophrenia. They represent distortions of reality and are not classified as negative symptoms. D: Waxy flexibility, where a person maintains a position after being placed in it by someone else, is a catatonic symptom and is not specifically categorized as a negative symptom. It is more related to motor behavior abnormalities.
