Correct Answer: B

Rationale: The correct answer is B: 'Violent behavior.' When a client has overdosed on PCP, the nurse should be particularly cautious about the manifestation of violent behavior. PCP overdose can lead to aggressive and unpredictable actions, posing a significant risk to both the client and healthcare providers. Visual hallucinations (choice A), bizarre behavior (choice C), and loud screaming (choice D) can also occur with PCP overdose, but the primary concern should be the potential for violent behavior, making it the most critical behavior to monitor and manage.

Correct Answer: B

Rationale: These symptoms are indicative of neuroleptic malignant syndrome (NMS), which is a severe and life-threatening reaction to neuroleptic drugs. The major symptoms include fever, rigidity, autonomic instability, and encephalopathy. Respiratory failure, cardiovascular collapse, arrhythmias, and/or renal failure can lead to death. This is an emergency situation requiring immediate critical care, thus the correct action is to transfer the client to the ICU (B). Seizure precautions (A) are not relevant in this scenario. Merely describing the symptoms to the charge nurse and documenting them (C) or taking no action assuming these are common side effects (D) fail to address the critical nature of the situation and the urgency of immediate intervention.

Correct Answer: A

Rationale: A shuffling gait and tremors may indicate extrapyramidal side effects (EPS) from risperidone. The nurse's priority action should be to administer an anticholinergic medication as it can help alleviate these symptoms associated with EPS. Documenting the findings and monitoring the client (Choice B) are important but addressing the immediate symptoms takes precedence. Assessing the client's blood glucose level (Choice C) is not directly related to the observed symptoms of shuffling gait and tremors. While notifying the healthcare provider (Choice D) is important, it is not the priority action when dealing with EPS symptoms.

Correct Answer: C

Rationale: The statement 'I can drink alcohol in moderation while taking this medication' indicates a need for further teaching because alcohol consumption can have dangerous interactions with MAOIs. MAOIs can interact with alcohol to cause a hypertensive crisis, which can be life-threatening. Choices A and B are correct statements as avoiding tyramine-rich foods and taking the medication with food can help prevent adverse effects. Choice D is incorrect because abruptly stopping an antidepressant medication like an MAOI can lead to withdrawal symptoms and a relapse of depression.

Correct Answer: D

Rationale: Explaining that the medication may take several weeks to take full effect helps manage the client's expectations and encourages adherence to the prescribed treatment.
