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. Summarize the objectives the client achieved during the relationship:
This intervention is more appropriate for the termination phase of the nurse-client relationship. During termination, the nurse summarizes the progress made, goals achieved, and skills learned during the therapeutic relationship. This helps both the nurse and the client reflect on the journey and celebrate accomplishments.

B. Present issues regarding confidentiality:
Discussing confidentiality is crucial and typically occurs in the orientation phase of the nurse-client relationship. Establishing trust and clarifying the boundaries of confidentiality early in the relationship helps the client feel secure and promotes open communication. This choice is relevant during the initial stages of the therapeutic relationship.

C. Promote the client's problem-solving skills:
This is the correct choice for the working phase of the nurse-client relationship. In this phase, the focus is on active problem-solving, exploring feelings and thoughts, and encouraging the client to develop coping strategies. The nurse supports the client in identifying problems, generating solutions, and implementing effective strategies. Promoting the client's problem-solving skills is a central aspect of therapeutic work during this phase.

D. Identify the responsibilities of the client and nurse:
Clarifying the responsibilities of both the client and nurse is essential to establish clear roles and expectations. This usually occurs in the orientation phase. During this phase, the nurse explains the purpose of the therapeutic relationship, the roles of both parties and the boundaries of the nurse-client interaction. Establishing clear responsibilities helps create a foundation for a respectful and effective therapeutic alliance.

A. Implement measures to prevent intentional self-inflicted injury:
This choice is the priority. Individuals with borderline personality disorder are at an increased risk of self-harm and suicidal behaviors. Implementing measures to prevent intentional self-inflicted injury, such as close monitoring, removing potentially harmful objects, and creating a safe environment, is crucial to ensuring the client's safety and well-being.

B. Discuss the appropriate use of assertive behavior with the client:
Teaching assertive behavior is an important aspect of therapy for individuals with borderline personality disorder. Learning to express emotions and needs in a healthy, assertive manner can improve their interpersonal skills and relationships. However, this choice is secondary to ensuring the client's safety. Safety concerns need to be addressed before moving on to other therapeutic interventions.

C. Encourage the client to attend weekly support group meetings:
Support group meetings can provide valuable social support and a sense of belonging for individuals with borderline personality disorder. Being part of a supportive community can offer understanding and coping strategies. While this is a beneficial intervention, it is not the priority. Safety concerns and addressing self-harm risk take precedence.

D. Assist the client to maintain awareness of her thoughts and feelings:
Developing self-awareness and emotional regulation skills is essential in managing borderline personality disorder. Techniques such as mindfulness and dialectical behavior therapy (DBT) can help individuals become more aware of their thoughts and emotions. While important for long-term management, this intervention is not the priority when immediate safety concerns are present. Safety should always be the first focus of care.
