The psychiatric nurse is talking to a newly admitted client when another male client, who is diagnosed with antisocial behavior, intrudes on the conversation and tells the nurse, "I have to talk to you right now! It is very important!" How should the nurse respond to this client?

A. Redirecting to another nurse does not set a clear boundary with the client. B. Ignoring (extinction) may escalate the behavior rather than appropriately managing it. C. Setting clear and firm boundaries helps maintain structure and prevents manipulation, which is a key component of managing clients with antisocial behavior. D. Introducing him to the newly admitted client and asking him to join the conversation may reinforce disruptive behavior.
