Which of the following symptoms is commonly associated with psychosis?

Hallucinations are a central symptom of psychosis and are characterized by perceiving things that are not present in reality, such as hearing voices or seeing things that others do not. This symptom is a hallmark of various psychiatric disorders, including schizophrenia, severe mood disorders, and substance-induced psychosis. The presence of hallucinations indicates a significant disruption in cognitive processing and perception, which is a key feature of psychotic disorders.

The other symptoms listed, while they can occur in various mental health conditions, are not specific indicators of psychosis. Muscle cramps, chronic fatigue, and regular headaches can result from a range of physical and psychological issues but do not reflect the altered perception of reality that defines psychosis. Understanding the primary symptoms of psychosis, including hallucinations, is essential for proper diagnosis and treatment planning in mental health nursing.
