A male client turns over a table in the dayroom of a psychiatric unit and threatens to throw a chair at another client. Which action is most important for the nurse to implement?

Correct Answer: B

Rationale: In a situation where a client is displaying aggressive behavior, the most important action for the nurse to implement is to obtain staff assistance to help diffuse the escalating situation. This approach ensures the safety of all individuals involved and prevents the situation from escalating further. Calmly approaching the client and removing the chair directly could agitate the client further and pose a risk to the nurse. Offering feedback about the client's behavior may not address the immediate safety concerns. Summoning hospital security guards as a 'show of force' should be a last resort after other de-escalation attempts have failed, as it may further provoke the client.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to administer acetylcysteine (Mucomyst). Acetylcysteine is the antidote for acetaminophen overdose and should be administered promptly to prevent liver damage. Monitoring cardiac rhythm for flat T waves (Choice B) is not specific to acetaminophen overdose and is more related to cardiac conditions. Checking serum AST and ALT levels (Choice C) may be done later but is not the initial priority in this situation. Similarly, preparing to administer Syrup of Ipecac (Choice D) is not recommended anymore in cases of overdose as it can cause more harm.

Correct Answer: B

Rationale: The best nursing intervention for a client with borderline personality disorder expressing fear of abandonment is to set limits on the client's behavior and enforce them consistently. This approach helps establish boundaries and provides a sense of security for the client. Choice A may provide temporary reassurance but does not address the core issue or help the client develop coping strategies. Choice C is important but should be accompanied by setting limits to address the underlying fear of abandonment. Choice D of rotating staff frequently can exacerbate the client's fear of abandonment by reinforcing the idea of being left.

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: A

Rationale: The correct answer is A. Reinforcing the importance of adhering to the prescribed medication regimen is crucial for preventing relapse in clients with schizophrenia. Compliance with medication is essential in managing the symptoms and preventing a worsening of the condition. Choice B, recognizing early signs of relapse, is important but secondary to ensuring medication adherence. Choice C, follow-up appointments, is also important but not as critical as medication compliance immediately post-discharge. Choice D, maintaining a healthy lifestyle, is beneficial for overall health but is not as directly linked to preventing relapse in schizophrenia as medication adherence.
