A nurse is collecting a history from a client who has depression. Which of the following statements by the client should the nurse identify as a protective factor against suicide?

A. "Since injuring my knee, I've decided to become the team manager."
Option A represents an adaptive use of the ego defense mechanism known as sublimation. Sublimation is a process in which a person channels potentially negative or harmful impulses or feelings into more socially acceptable and constructive activities. In this case, the adolescent with the injured knee is using the opportunity to become the team manager, which is a positive and constructive way to stay engaged with the team despite the setback of the injury.

B. "Since my mom died, I focus all my attention on my grades."
This is an example of reaction formation, a defense mechanism where someone overemphasizes the opposite of their true feelings. In this case, the individual might be hiding or avoiding their grief by focusing on grades.

C. "I didn't tell the teacher about the bullying because it wouldn't have changed anything."
This is an example of rationalization, where the individual provides a logical-sounding but potentially inaccurate explanation for their actions. It can be a defense mechanism to justify or make more acceptable one's choices.

D. "I'm not even going to think about writing that thesis paper until after prom."
This is an example of procrastination or avoidance, which is not an ego defense mechanism but a coping or time-management strategy. It doesn't represent an adaptive use of a defense mechanism in this context.

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.
