Correct Answer: C

Rationale: Initially, the nurse should allow time for the ritualistic behavior (C) to prevent anxiety. Administering an antianxiety medication (A) may help reduce the client's anxiety temporarily but will not address the underlying issue of ineffective coping mechanisms leading to the behavior. While assisting the client in identifying triggers (B) is important for long-term therapy, the immediate focus should be on managing the behavior. Teaching relaxation and thought-stopping techniques (D) is beneficial but might be more effective once the client is more stable and receptive to learning new coping strategies.

Correct Answer: C

Rationale: Maintaining a consistent sodium intake is crucial for clients taking lithium because changes in sodium levels can impact lithium concentrations, potentially leading to toxicity. It is essential to avoid excessive sodium intake, as both low and high levels can affect lithium levels. Choices A, B, and D are incorrect. A high potassium diet is not a concern with lithium therapy. While taking lithium with food can help reduce gastrointestinal side effects, it is not the most important instruction. Finally, abruptly stopping lithium can lead to a recurrence of symptoms or a worsening of the condition, so it is vital to follow the prescribed regimen.

Correct Answer: B

Rationale: The correct answer is B. Buspirone typically takes 2 to 4 weeks to become fully effective. It is essential to inform the client that it may take some time before they notice an improvement. Choice A is incorrect because buspirone does not work immediately. Choice C is also incorrect as buspirone does not provide immediate relief. Choice D is incorrect as it suggests a longer duration of treatment than necessary.

Correct Answer: C

Rationale: Allowing the group to handle the situation is the best action as it promotes group dynamics and empowerment, especially since the group is in the working phase. Talking to the participant individually (A) might be seen as manipulative. Reminding the participant (B) can come across as dictatorial and may not address the underlying issue. Asking the participant to join another group (D) does not address the problem at hand and avoids the opportunity for growth and conflict resolution within the current group.

Correct Answer: D

Rationale: In this scenario, the best response for the nurse is to offer presence and a safe environment without validating the delusion or arguing with the client. By inviting the client to the room and offering to sit with her, the nurse is providing support and reassurance. Choice A is incorrect because directly denying the client's belief may escalate the situation. Choice B is inappropriate as it dismisses the client's concerns without addressing the underlying issue. Choice C acknowledges the client's feelings but does not provide immediate support or safety, unlike Choice D which offers both.
