Correct Answer: A

Rationale: The correct answer is A: Persistent thoughts about the trauma. In post-traumatic stress disorder (PTSD), individuals often experience persistent intrusive thoughts about the traumatic event, which can be distressing and disruptive. This symptom is a hallmark feature of PTSD. Choices B, C, and D are incorrect because increased energy, enthusiasm, decreased need for sleep, increased appetite, and weight gain are not typical symptoms of PTSD. Instead, individuals with PTSD may commonly experience symptoms such as flashbacks, nightmares, hypervigilance, avoidance of triggers related to the trauma, and negative changes in mood and cognition.

Correct Answer: C

Rationale: Escorting the client out of the bathroom is the most appropriate action to take in this situation. This helps prevent further inappropriate behavior and maintains hygiene, while avoiding reinforcement of the behavior. Option A, explaining that the feces belong in the toilet, may not be effective as the behavior is likely a manifestation of the client's condition rather than a lack of understanding. Option B, showing the client how to clean the walls, may not address the underlying issue and could potentially reinforce the behavior. Option D, assisting the client to clean the walls, may also reinforce the behavior and is not the best approach to managing the situation.

Correct Answer: D

Rationale: When dealing with a client experiencing auditory hallucinations, it is crucial for the nurse to first listen to what the client is saying. Auditory hallucinations may hold significance to the client, and by actively listening, the nurse can gather information about the content and context of the hallucinations. This information helps the nurse assess the client's current state, emotional responses, and the potential triggers for the behavior. Administering a PRN sedative (Choice A) should not be the initial action as it may suppress important information and feelings the client is trying to communicate. Sitting next to the client (Choice B) may not be appropriate without understanding the situation better. Escorting the client to his room (Choice C) may escalate the situation without addressing the underlying cause of the behavior, which can be better understood through active listening.

Correct Answer: D

Rationale: Nausea and vomiting are signs of potential lithium toxicity, which is a serious condition requiring immediate attention. These symptoms can indicate a dangerous level of lithium in the body that can lead to severe complications. Short-term memory loss (A), five-pound weight gain (B), and decreased affect (C) are important to monitor but are not as immediately concerning as symptoms of potential toxicity like nausea and vomiting.

Correct Answer: B

Rationale: The correct action for the charge nurse is to advise the client that assignments are not based on client requests. Clients with antisocial personality disorder may attempt to manipulate situations to their advantage. By setting clear boundaries and explaining that assignments are not based on client preferences, the nurse helps prevent manipulation and maintains a professional approach to care. Reassuring the client about his requests (Choice A) may encourage the inappropriate behavior to continue. Asking the client to explain his requests (Choice C) may further fuel the manipulation by providing an opportunity for the client to justify his actions. Encouraging the client to verbalize feelings (Choice D) does not address the underlying issue of manipulating the assignment process and may inadvertently reinforce the behavior.
