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?

A. Long-term isolation: Long-term isolation, or social isolation, can lead to feelings of loneliness and depression. While prolonged isolation can contribute to mental health issues, it is not a direct risk factor for violent behavior. People who are socially isolated might suffer from emotional distress, but it doesn't necessarily make them violent.

B. Dysthymic disorder: Dysthymic disorder, also known as persistent depressive disorder, is a type of chronic depression. While individuals with dysthymic disorder may experience low moods and a lack of interest in activities, it doesn't inherently make them prone to violence. Depression is more likely to cause self-directed harm (such as self-harm or suicide) rather than violent behavior towards others.

C. Alcohol intoxication: Alcohol is a substance that impairs judgment and reduces inhibitions. When a person is intoxicated, they may act aggressively or violently, even in situations where they wouldn't normally do so. Alcohol intoxication can lead to a loss of control, impaired decision-making, and aggressive behavior, making it a significant risk factor for violent actions.

D. Schizoid personality disorder: Schizoid personality disorder is characterized by a lack of interest in social relationships, emotional coldness, and detachment. While individuals with this disorder may prefer to be alone and avoid social interactions, they are not necessarily prone to violent behavior. Schizoid personality disorder primarily affects social functioning rather than predisposing someone to violence.

A. Takes advantage of others for her own benefit:
This behavior is not specific to paranoid personality disorder. Instead, it may be seen in individuals with antisocial personality disorder, who disregard the rights of others and exploit them for personal gain. People with paranoid personality disorder are more characterized by a pervasive distrust of others and a belief that others are out to harm or deceive them.

B. Believes that others are deceiving her:
This is a hallmark symptom of paranoid personality disorder. Individuals with this disorder often exhibit extreme distrust and suspicion, believing that others have hidden motives or are deliberately trying to deceive, harm, or manipulate them. This suspiciousness and belief in the untrustworthiness of others are key features of paranoid personality disorder.

C. Shows exaggerated expression of emotions:
Exaggerated expression of emotions is not a defining characteristic of paranoid personality disorder. People with this disorder tend to display a guarded and suspicious demeanor rather than exaggerated emotional expressions. Their interpersonal interactions are often marked by skepticism and wariness.

D. Demonstrates detachment from others:
Detachment from others is more characteristic of schizoid personality disorder, not paranoid personality disorder. Individuals with schizoid personality disorder tend to be emotionally detached and have limited interest in social interactions. In contrast, individuals with paranoid personality disorder are highly suspicious and tend to assume that others are hostile or malevolent, leading to interpersonal difficulties rooted in their intense distrust.
