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 nurse should first ask if the client is ever alone when she hears the voices. This question helps differentiate between potential auditory hallucinations and other causes like hearing loss. Choice A is not the best first question as it assumes the client is experiencing hallucinations without exploring other possibilities. Choice C is irrelevant to the immediate concern of hearing voices. Choice D pertains to visual hallucinations which are not described in the client's complaint of hearing voices.

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: B

Rationale: The correct answer is B: Increased self-understanding. According to Erikson's psychosocial development theory, middle adulthood is characterized by generativity, self-reflection, understanding, and acceptance. Middle-aged adults focus on guiding the next generation and finding meaning in their lives. Choices A and C are incorrect because loss of independence and isolation from society are maladaptive behaviors in middle adulthood. While developing and maintaining intimate relationships is important throughout life, the initial development of intimate relationships typically occurs during young adulthood, not middle adulthood.

Correct Answer: D

Rationale: The correct answer is 'High risk for injury.' The client's agitation, elevated vital signs, and aggressive behavior pose a threat to himself and his family. Addressing the risk for injury is the priority to ensure the safety of all individuals involved. Choices A, B, and C are not the highest priority in this scenario. 'High risk for social isolation' does not address the immediate physical safety concern. 'Altered parenting' and 'Ineffective individual coping' are important but not as urgent as the risk for injury in this situation.
