Correct Answer: B

Rationale: The initial priority for the nurse is to ensure the safety of the client. Placing the client on one-to-one observation allows for constant monitoring and intervention if there are any signs of self-harm or a worsening condition. This immediate intervention is crucial to prevent further harm. Options A, C, and D involve therapeutic communication and interventions, which are important but should come after ensuring the client's safety.

Correct Answer: C

Rationale: Palpitations are not typically associated with moderate anxiety. Fidgeting, laughing inappropriately, and nail biting are common behavioral symptoms of heightened stress levels. Palpitations may be more indicative of physiological responses, such as increased heart rate, which can occur in severe anxiety or panic attacks. Other signs of severe anxiety include restlessness, difficulty concentrating, muscle tension, and sleep disturbances.

Correct Answer: A

Rationale: The initial intervention for a client experiencing auditory hallucinations, especially in schizophrenia, is to assess the content of the hallucinations. By asking the client to describe the hallucinations, the nurse can determine if they are command hallucinations that might pose a risk. This assessment is crucial in guiding further appropriate interventions to ensure the client's safety and well-being. Instructing the client to ignore the hallucinations (Choice B) may not be effective, as the hallucinations are real to the client. Administering antipsychotic medication (Choice C) may be necessary but should come after assessing the situation. Engaging the client in reality-based activities (Choice D) is important but not the first priority when dealing with auditory hallucinations.

Correct Answer: D

Rationale: Borderline personality disorder is characterized by an intense fear of abandonment, unstable relationships, impulsivity, and chronic feelings of emptiness. Grandiosity, which involves an exaggerated sense of self-importance and superiority, is more commonly associated with narcissistic personality disorder rather than borderline personality disorder. Therefore, the correct answer is D.

Correct Answer: D

Rationale: Post-traumatic stress disorder (PTSD) is characterized by various symptoms, including flashbacks, avoidance of reminders of the trauma, increased arousal, and hypervigilance. Additionally, individuals with PTSD often experience negative changes in thoughts and mood. Manic episodes, which are periods of abnormally elevated mood and energy, are not typically associated with PTSD. Therefore, the correct answer is 'Manic episodes.' Choices A, B, and C are all common findings in individuals with PTSD.
