A nurse is caring for a client who has a new diagnosis of metastatic lung cancer. The client states, "I can't think about that until after my first grandchild is born next week." The nurse should identify the client's statement as indicating the maladaptive use of which of the following defense mechanisms?

Choice A reason: Suppression is a conscious defense mechanism where an individual intentionally avoids thinking about disturbing thoughts or feelings. In this case, the client is choosing to delay addressing the reality of their diagnosis until after a significant family event. This can be seen as a temporary coping strategy to manage overwhelming emotions, but it may become maladaptive if overused or if it prevents the client from seeking necessary treatment and support. Choice B reason: Compensation involves overachieving in one area to make up for deficiencies in another. The client's statement does not suggest that they are trying to compensate for their illness by excelling in other areas of life; rather, they are postponing the emotional processing of their diagnosis. Choice C reason: Regression is a return to earlier stages of development and coping strategies, often under stress. The client's statement does not indicate a regression to more childlike behaviors or earlier developmental stages. Choice D reason: Sublimation is a way of channeling unacceptable impulses into socially acceptable actions. The client's statement does not reflect the use of sublimation, as they are not redirecting their feelings about the diagnosis into a different, more acceptable outlet.
