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: D

Rationale: The correct answer is to refer the client for a psychiatric evaluation. The client's statement indicating hearing voices telling them to hurt themselves is a serious concern and suggests a risk for self-harm. Referring the client for a psychiatric evaluation is crucial for further assessment and intervention by mental health professionals. Choice A is incorrect because ignoring the voices may not address the client's safety. Choice B is incorrect as it oversimplifies the situation and does not address the immediate risk. Choice C is not as comprehensive as referring for a psychiatric evaluation, which is necessary in this situation.

Correct Answer: D

Rationale: During the working phase of the nurse-client relationship, it is crucial for the nurse to inquire about and examine the client's feelings that may hinder adaptive coping. This helps the client process the traumatic event, explore their emotional responses, and identify any barriers to moving forward effectively. Exploring the client's ability to function (Choice A) may be more relevant in the assessment phase, while exploring the client's potential for self-harm (Choice B) is important but may not be the primary focus at this stage. Inquiring about the client's perception of the neighbor's death (Choice C) is valuable, but addressing feelings blocking adaptive coping is essential for therapeutic progress.

Correct Answer: B

Rationale: The correct intervention for a client with bulimia nervosa is to observe the client for 30 minutes after meals. This helps prevent purging behaviors, such as vomiting or using laxatives, which are common in bulimia nervosa. Choice A is incorrect because eating meals alone may enable the client to engage in purging behaviors without being observed. Choice C is incorrect as a high-calorie diet may exacerbate the client's concerns about weight gain. Choice D is incorrect because encouraging daily weigh-ins can reinforce obsessive thoughts about weight and body image.

Correct Answer: B

Rationale: The best nursing intervention for a client with OCD who spends excessive time checking locks is to encourage the client to discuss the thoughts and feelings behind the behavior. By exploring the underlying anxiety and triggers, the client can gain insight and work towards behavior modification. Choice A is incorrect because enabling the behavior does not address the underlying issues. Choice C is incorrect as it may lead to increased anxiety and distress. Choice D is incorrect as it does not address the root cause of the behavior.
