Correct Answer: C

Rationale: The correct answer is C: White blood cell count. Clozapine can lead to agranulocytosis, a severe drop in white blood cells, which can be life-threatening. Monitoring the white blood cell count is crucial to detect this condition early. Choices A, B, and D are incorrect because while liver and kidney function tests are important in monitoring other aspects of health, the most critical concern with clozapine therapy is the risk of agranulocytosis, making monitoring white blood cell count the priority.

Correct Answer: B

Rationale: Administering a PRN dose of antipsychotic medication is the first action the nurse should take to manage symptoms of anxiety in a client being treated with haloperidol. The priority is to address the client's escalating anxiety and pacing behavior, which can be managed effectively by providing additional antipsychotic medication. Asking the client to sit down and relax (Choice A) may not be effective if the anxiety is due to inadequate medication levels. Encouraging the client to talk about what is making him anxious (Choice C) may not be beneficial in this acute situation and can be considered after addressing the immediate need for symptom management. Monitoring for adverse reactions (Choice D) is important but is not the first action to take when the client is showing signs of increasing anxiety and agitation.

Correct Answer: B

Rationale: The correct answer is to tell the client that the nurse is there and will help her. Providing reassurance and presence is more therapeutic in dealing with a client who has advanced dementia and is expressing a desire to go home and be with her mother. Option A might not be effective as continuously orienting the client may not alleviate her distress. Option C, reminding the client that her mother is no longer living, can be distressing and may not be appropriate in this situation. Option D, explaining the seriousness of the injury and need for hospitalization, is not the best response as it does not address the client's emotional needs at that moment.

Correct Answer: C

Rationale: Teaching the client that the medication may take 4 to 6 weeks to become fully effective is crucial as it helps set realistic expectations. While choice A is important to reduce nausea, it is not the most critical information to provide initially. Choice B is incorrect as improvement usually occurs after several weeks of treatment, not within 1 to 2 weeks. Choice D is also relevant, but informing about the full effectiveness of the medication is more important for long-term adherence.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests. Valproic acid can cause hepatotoxicity, leading to liver damage. Monitoring liver function tests is crucial to detect any early signs of liver impairment. Kidney function tests (Choice B) are not the most important to monitor in this case. Blood glucose levels (Choice C) and serum sodium levels (Choice D) are not directly affected by valproic acid and are not the priority for monitoring in a client taking this medication.
