Correct Answer: C

Rationale: In situations where a client is responding to auditory hallucinations and displaying aggressive behavior, it is crucial for the nurse to ensure physical space between themselves and the client. This action can help de-escalate the situation and prevent any potential harm to both the nurse and the client. Sitting down near the client (Choice A) may escalate the situation by invading the client's personal space. Positioning oneself within an arm's length of the client (Choice B) may increase the risk of physical confrontation. Moving closer to the room's door (Choice D) may not be appropriate as it can block the client's exit route and escalate the situation further. Therefore, ensuring physical space between the nurse and the client (Choice C) is the most appropriate action to promote safety and prevent escalation.

Correct Answer: A

Rationale: The best nursing intervention when dealing with a client with OCD who repeatedly checks locks is to encourage the client to discuss their fears. This approach can help the client identify underlying anxiety triggers and work towards developing alternative coping mechanisms. Choice B, limiting the client's time for ritualistic behavior, may increase anxiety and worsen symptoms by creating a sense of urgency. Choice C, assisting the client to complete the ritual faster, does not address the underlying issues and may reinforce the behavior. Choice D, preventing the client from engaging in the behavior, can lead to increased anxiety and distress for the client.

Correct Answer: B

Rationale: The correct answer is B: 'The death of a loved one.' A situational crisis, like the death of a loved one, can lead to anxiety due to a significant change or loss in the person's life. Choices A, C, and D involve traumatic events, but a situational crisis typically refers to life events that disrupt an individual's normal pattern of living, such as the death of a loved one.
