A nurse is conducting a group therapy session for several clients. The group is laughing at a joke one of the clients told, when a client who is schizophrenic jumps up and runs out of the room yelling, "You are all making fun of me!" The nurse should identify this behavior as which of the following characteristics of schizophrenia?

A. Delusions of grandeur: This involves the false belief that one is a very powerful, important, or famous person (e.g., believing one is the President or a religious deity). B. Ideas of reference: Ideas of reference involve the false belief that irrelevant or neutral occurrences in the world relate directly to oneself. In this scenario, the client misinterprets the group's laughter (a neutral event regarding a joke) as being directed specifically at them ("making fun of me"). C. Magical thinking: This is the belief that one's thoughts, words, or actions can cause or prevent things from happening in the external world (e.g., "It rained because I was sad"). D. Looseness of association: This refers to a pattern of speech where ideas shift from one subject to another that is completely unrelated, making the conversation difficult to follow.
