Correct Answer: C

Rationale: The best response for the nurse is to discuss relaxation techniques with the client that can help reduce anxiety and stress before bedtime. This approach may potentially decrease the frequency of nightmares by promoting a more calming and peaceful pre-sleep routine. Choice A is incorrect because while nightmares can be common with PTSD, it is not guaranteed that they will decrease over time. Choice B is incorrect as avoiding thinking about the trauma may not address the underlying issue causing the nightmares. Choice D is incorrect as prescribing a sleep aid should be considered as a last resort after trying non-pharmacological interventions.

Correct Answer: B

Rationale: The correct answer is B: 'Keep your dietary salt intake consistent.' Consistent salt intake is crucial when taking lithium carbonate to avoid lithium toxicity or ineffectiveness due to its renal excretion mechanism. Option A is incorrect because it focuses on the time to achieve therapeutic effects, which is important but not as critical as maintaining consistent salt intake. Option C is incorrect as it mentions avoiding aged cheese and chicken liver, which is more relevant for individuals taking MAOIs. Option D is incorrect as it suggests eating high-fiber foods, which is not directly related to lithium carbonate therapy.

Correct Answer: B

Rationale: When a client with bipolar disorder expresses a desire to stop taking lithium because they feel fine, the nurse's initial action should be to remind the client of the importance of lithium. This approach helps educate the client about the necessity of medication adherence in managing bipolar disorder. Agreeing with the client or immediately arranging a psychiatric evaluation may not address the root issue of medication non-adherence. Asking the healthcare provider to discontinue the prescription without further assessment and intervention could potentially jeopardize the client's stability and treatment plan.

Correct Answer: A

Rationale: Acknowledging the client's non-verbal behavior, such as looking out the window, demonstrates active listening and provides the client with an opportunity to explore their feelings further. Choice B is incorrect as it accuses the client of lying without any evidence, which can damage the therapeutic relationship. Choice C is inappropriate as it dismisses the client's feelings and suggests a group discussion without addressing the client's emotions directly. Choice D is also incorrect as it focuses on the children's actions rather than the client's feelings, missing an opportunity for therapeutic communication.

Correct Answer: C

Rationale: A sudden improvement in mood and declaring being cured can be warning signs of a decision to attempt suicide. Therefore, the appropriate action would be to increase the level of suicide precautions to ensure the safety of the client. This can involve closer monitoring and restriction of items that could be harmful. Choices A, B, and D are incorrect as they do not address the potential risk of suicide that may be present with the sudden change in behavior.
