When a client claims to be a movie star surrounded by an audience, what conclusion should the nurse draw about the client's experience?

The correct conclusion is that the client's experience represents a delusion of grandeur. This condition involves a false belief in one’s own exceptional abilities, wealth, or fame. When a client claims to be a movie star and believes they have an audience, they are exhibiting an exaggerated sense of self-importance and an unrealistic view of their identity and capabilities. This type of delusion can often be seen in various psychiatric conditions, including bipolar disorder and schizophrenia.

In contrast, hallucinations refer to perceptual experiences where an individual hears, sees, or feels things that are not present; the scenario described does not indicate sensory experiences but rather a belief about oneself. Personality disorders encompass a wide range of long-standing patterns of behavior and inner experiences but do not specifically address the grandiosity exemplified here. Schizotypal behavior refers to peculiar or eccentric behavior but does not specifically denote the grandiose belief in fame. Thus, the scenario most accurately aligns with the definition of a delusion of grandeur.
