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: C

Rationale: The correct answer is C. Describing oneself as a social drinker who consumes alcoholic beverages daily raises concerns about potential alcohol abuse issues. The CAGE questionnaire is a tool used to screen for alcohol use disorder. Choice A is incorrect as memory difficulties post-traumatic brain injury do not directly indicate a need for the CAGE questionnaire. Choice B is incorrect as the use of antidepressants, while important to note, does not specifically warrant the use of the CAGE questionnaire. Choice D is incorrect as a recent sexual assault, while significant, does not directly relate to the need for alcohol abuse screening using the CAGE questionnaire.

Correct Answer: C

Rationale: In this situation, where the manic client becomes verbally abusive and threatens physical violence, the most appropriate action for the LPN/LVN is to escort the client to her room with assistance. This action helps ensure the safety of both the client and the nurse, while also providing a controlled environment that can help de-escalate the situation. Choices A and B do not address the immediate safety concerns presented by the client's behavior. Choice D, revoking smoking privileges, is not directly related to the client's current behavior and does not address the threat of violence.

Correct Answer: B

Rationale: The most appropriate nursing intervention for a client with difficulty sleeping due to depression and prescribed fluoxetine is to suggest the client drink a warm beverage before bedtime. This intervention can promote relaxation and help establish a bedtime routine, potentially improving sleep quality. Encouraging short naps during the day (Choice A) may disrupt the client's nighttime sleep schedule. Recommending exercise immediately before bedtime (Choice C) can have a stimulating effect, making it harder for the client to fall asleep. Advising the client to take a sleep aid nightly (Choice D) should only be done under the guidance of a healthcare provider due to potential interactions with fluoxetine.

Correct Answer: A

Rationale: The nurse should be most concerned that the client may act on suicidal thoughts. An increase in energy combined with persistent feelings of hopelessness can indicate a higher risk of suicide. While impulsive behavior can be a concern, the primary worry should be the client's safety regarding suicidal ideation. Side effects of the medication are important to monitor but do not take precedence over the risk of self-harm. Serotonin syndrome is a potential concern with SSRIs, but in this scenario, the client's mental health and safety are the immediate priority.
