Correct Answer: C

Rationale: The correct answer is 'Impulsive.' Clients with borderline personality disorder often exhibit impulsive, potentially self-damaging behaviors. Arrogance is more characteristic of narcissistic personality disorder, eccentric behavior aligns with schizotypal personality disorder, and dependent behavior is typical of dependent personality disorder. Therefore, the key feature of borderline personality disorder is impulsivity.

Correct Answer: B

Rationale: A mild level of anxiety can be beneficial because it increases alertness and focuses attention. Physiological functions are actually amplified initially, not slowed, due to mild apprehension; however, prolonged anxiety can lead to decreased function due to exhaustion. Automatic behavioral responses and ego defense mechanisms may hinder an individual's awareness rather than enhancing it, making them less beneficial compared to increased alertness.

Correct Answer: C

Rationale: The most appropriate response to the client's question regarding their prognosis is to acknowledge the variable nature of multiple sclerosis by stating that 'The prognosis varies, as most individuals have remissions and exacerbations.' This response provides realistic information while offering some hope. Choice A ('Most individuals with your disease live a normal life span.') gives false reassurance as repeated exacerbations may affect life span. Choice B ('Is your family here? I would like to explain your disease to all of you.') does not directly address the client's question and involves the family unnecessarily. Choice D ('Why don't you speak with your health care provider to get more details?') deflects the responsibility and does not address the client's immediate concerns about their prognosis.

Correct Answer: B

Rationale: In the orientation phase of the nurse-client relationship, setting boundaries involves establishing the nurse's role and responsibilities while maintaining a professional distance. Option B demonstrates a clear boundary by introducing the nurse and offering assistance with settling in, which is appropriate for the initial phase of building rapport with the client. Choices A, C, and D delve into personal or therapeutic topics that are more suitable for the working phase of the relationship when the client's goals and problems are being addressed. Asking about the client's family relationships (Choice A), therapy focus (Choice C), or delving into the client's depression (Choice D) would be more relevant in later stages of the therapeutic process, once trust and rapport have been established during the orientation phase.

Correct Answer: C

Rationale: The nurse would say, ''It seems like the world is a pretty scary place for you.'' This response allows the nurse to understand the symbolism, reflect on and acknowledge the client's feelings, and help preserve the client's integrity. The statement, ''Tell me more about being Joan of Arc,'' validates the client's delusion and does not test reality. The statement, ''We both know that you're not Joan of Arc,'' rejects the client's feelings and does not address the client's fears of being harmed; clients cannot be argued out of delusions. The statement, ''You're safe here, because we won't let you be burned,'' is false reassurance; the nurse is agreeing with the client's false perceptions of reality, which is nontherapeutic.
