Correct Answer: C

Rationale: The correct answer is to assess the client's risk for suicide. When a client expresses feelings of hopelessness and helplessness, it indicates a high risk of self-harm or suicide. Therefore, the priority intervention should be to assess the client's safety. Encouraging the client to join a support group (choice A) may be beneficial but not the priority at this time. Referring the client for cognitive-behavioral therapy (CBT) (choice B) and suggesting daily exercise (choice D) are important interventions in managing depression but assessing the risk for suicide takes precedence due to the immediate safety concern.

Correct Answer: A

Rationale: Acute confusion is the priority problem as it directly affects the client's ability to process information and make safe decisions. In this scenario, the client's disorientation, disorganization, and confusion indicate an immediate cognitive issue that requires attention to ensure her safety and stability. Choices B, C, and D are not the priority problems in this case. Ineffective community coping, disturbed sensory perception, and self-care deficit, while important, are secondary to the client's acute confusion, which poses an immediate risk to her well-being.

Correct Answer: C

Rationale: The correct answer is C: Sun-downing syndrome. Sun-downing syndrome is a phenomenon commonly seen in individuals with dementia, where they exhibit increased confusion and agitation in the late afternoon or evening. This pattern of behavior is believed to be linked to disruptions in the circadian rhythm and can be triggered by factors such as fatigue, low lighting, or increased shadows during the evening. Choices A and B, anxiety and depression, may be comorbid conditions in individuals with dementia but are not the primary explanation for the symptoms described. While medication side effects (Choice D) should always be considered in a client with dementia, given the time-specific nature of the symptoms, sun-downing syndrome is the most likely explanation in this case.

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.
