A nurse is caring for a client who states, "I smoke because I have a lot of anxiety." The nurse should recognize the client's statement as which of the following defense mechanisms?

Rationale A. Sublimation: Sublimation involves channeling unacceptable impulses into socially acceptable or constructive activities, such as exercising or creating art. Smoking to manage anxiety does not transform the impulse into a positive behavior, so this does not fit. B. Projection: Projection occurs when an individual attributes their own unacceptable feelings or impulses onto someone else. The client is not blaming others for their anxiety or behavior, so projection is not demonstrated here. C. Rationalization: Rationalization involves justifying behaviors with seemingly logical reasons to avoid confronting the true underlying feelings. The client explains smoking as a way to manage anxiety, providing a rational explanation for a behavior that may have deeper psychological or habitual roots. D. Dissociation: Dissociation involves disconnecting from reality or separating oneself from thoughts, feelings, or identity. The client remains aware of their behavior and feelings, so dissociation is not applicable in this scenario.
