Correct Answer: B

Rationale: The correct answer is B. Intelligence is indeed influenced by social and cultural beliefs. It is essential to recognize that intelligence is not solely determined by innate abilities but can also be shaped by various external factors such as cultural background, education, and social environment. Choices A, C, and D are incorrect because acute psychiatric illnesses do not necessarily impair intelligence, poor concentration skills do not always suggest limited intelligence, and the inability to think abstractly alone does not always indicate limited intelligence.

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: C

Rationale: The most important nursing problem is medication management (C) because compliance with the medication regimen will help prevent hospitalization. The client is also exhibiting signs of mania, such as excessive work activity (A), decreased need for sleep (B), and inflated self-esteem (D); however, these problems do not have the priority of medication management. Managing the medications is crucial to stabilize the client's condition and prevent potential harm associated with untreated bipolar disorder.

Correct Answer: B

Rationale: During a manic state, individuals with bipolar disorder may exhibit hyperactivity, impulsivity, and reduced need for sleep. Providing a structured environment with reduced stimuli is the most therapeutic nursing intervention as it can help manage the client's excessive energy and prevent overstimulation. Choice A is incorrect as allowing the client to engage in any activity they choose may exacerbate their symptoms or lead to risky behaviors. Choice C, encouraging the client to express their thoughts freely, may not be appropriate during a manic state as it can further escalate their racing thoughts. Choice D, placing the client in a room with another client for socialization, may not be beneficial during a manic episode as it could increase stimulation and potentially lead to agitation.

Correct Answer: D

Rationale: The correct response is D. Respecting the client's privacy while acknowledging the difficulty of the situation and explaining the professional obligation to maintain confidentiality is the most therapeutic approach. This response shows empathy, understanding, and a commitment to confidentiality, which can help build trust and encourage the client to open up. Choices A, B, and C do not effectively address the client's concerns or emphasize the importance of confidentiality in a sensitive manner, making them less therapeutic responses in this situation.
