Final answer:
A nurse identifies positive symptoms of schizophrenia by observing hallucinations, delusions, disorganized speech, and catatonic behavior, which are active manifestations of psychosis.
Step-by-step explanation:
Understanding Positive Symptoms in Schizophrenia
When a nurse assesses a client with schizophrenia and notes positive symptoms, they are identifying active manifestations of psychosis that are not present in healthy individuals. The positive symptoms of schizophrenia include:
- Hallucinations - Sensory experiences that appear real but are created by the mind, such as hearing voices.
- Delusions - Strongly held false beliefs that are not based in reality and may be paranoid, grandiose, or bizarre.
- Disorganized speech - Difficulty organizing thoughts and speaking coherently, often resulting in jumbled or incoherent conversation.
- Catatonic behaviour - Markedly decreased reactivity to the environment, which can manifest as lack of movement or speech.
A nurse observing these symptoms would not include flat affect in the list of positive symptoms, as flat affect is considered a negative symptom, characterized by a diminished emotional expression or a lack of emotional responsiveness.
