Correct Answer: A

Rationale: Setting a time limit for hand washing is an effective intervention in managing obsessive-compulsive disorder (OCD) symptoms. By establishing boundaries around the behavior, the client can gradually work towards reducing the excessive hand washing and regaining control over the compulsion. Choice B is not as effective because it does not address the underlying compulsion. Choice C may not be helpful as it may not satisfy the client's need for cleanliness and could reinforce the behavior. Choice D, while important in therapy, may not be the most immediate intervention needed to address the excessive hand washing behavior.

Correct Answer: B

Rationale: In this scenario, the most appropriate response for the nurse is option B. By acknowledging the client's feelings and setting a boundary regarding inappropriate behavior, the nurse addresses the situation with empathy. This response demonstrates understanding of the client's emotions while also maintaining a professional standard by expressing discomfort with swearing. Option A could come off as defensive and may escalate the situation. Option C may be perceived as condescending and not immediately address the client's behavior. Option D, although offering space, does not directly address the inappropriate behavior and misses an opportunity to set a professional boundary.

Correct Answer: B

Rationale: The correct answer is B: Instability in relationships. Individuals with borderline personality disorder often exhibit instability in their relationships, characterized by intense and unstable interpersonal connections, oscillating between idealization and devaluation. This pattern can lead to frequent conflicts, dramatic emotional shifts, and difficulties maintaining stable relationships. Choices A, C, and D are incorrect. While individuals with borderline personality disorder may also have an excessive need for attention, fear of abandonment, or lack of interest in activities, the hallmark feature defining this disorder is the instability in relationships.

Correct Answer: C

Rationale: Apathy is a negative symptom of schizophrenia characterized by a lack of interest or motivation. Negative symptoms involve a decrease or absence of normal functions, such as emotions, motivation, or socialization, rather than the presence of abnormal behaviors like hallucinations or delusions. Hallucinations (choice A) and delusions (choice B) are positive symptoms, which involve the presence of abnormal behaviors. Disorganized speech (choice D) is an example of a disorganized symptom, not a negative symptom.

Correct Answer: B

Rationale: In individuals with post-traumatic stress disorder (PTSD), hypervigilance is a common symptom. Hypervigilance refers to a state of increased alertness, awareness, and sensitivity to potential threats or danger. This heightened state of vigilance can manifest as being easily startled, having difficulty relaxing or sleeping, and constantly scanning the environment for signs of danger. It is an adaptive response to the trauma experienced and can significantly impact the individual's daily functioning. The other options are not typically associated with PTSD. Delusions of grandeur are more commonly seen in certain psychiatric disorders like bipolar disorder or schizophrenia. Obsessive-compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD), not PTSD. Periods of excessive sleeping may be seen in conditions like depression, but they are not a hallmark symptom of PTSD.
