A client on the psychiatric unit appears to imitate a certain nurse on the unit. The client seeks out this particular nurse and imitates her mannerisms. Which defense mechanism does the nurse recognize in this client?

Correct Answer: B

Rationale: Identification is the correct answer. It is a defense mechanism where an individual unconsciously models themselves after someone they admire or feel close to. In this scenario, the client is imitating the nurse's mannerisms, indicating identification. Sublimation involves channeling unacceptable impulses into socially acceptable activities. Introjection is the internalization of external attitudes or voices, while repression involves suppressing unwanted thoughts or desires.

Correct Answer: A

Rationale: Approaching the client and asking if he is hearing voices is the best initial response by the nurse. This action can help assess the situation and determine if the client is experiencing hallucinations that may require immediate intervention. Choice B is incorrect because ignoring the behavior could lead to missing important signs of distress or potential risks. Choice C may not address the immediate concern of assessing for hallucinations. Choice D is also not ideal as observing from a distance may not provide the necessary information for immediate assessment and intervention.

Correct Answer: A

Rationale: The correct answer is A. Recognizing and challenging negative thoughts is a fundamental aspect of cognitive-behavioral therapy (CBT). In this statement, the client demonstrates insight into the fact that their negative thoughts may not always be accurate, showing progress in reframing their thoughts. Choice B indicates some improvement in functioning but does not directly relate to the core principles of CBT. Choice C is concerning as abruptly stopping antidepressant medication can be detrimental to the client's well-being. Choice D reflects avoidance behavior, which is typically a target for intervention in CBT rather than a sign of positive progress.

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: A

Rationale: The correct answer is A: "It may take several weeks for the medication to take effect." SSRIs typically take several weeks to reach their full effect, and it's important to set realistic expectations for the client. Choice B is incorrect because stopping the medication abruptly can lead to withdrawal symptoms and worsening of depression. Choice C is unrelated to SSRI therapy and pertains more to MAOIs. Choice D is incorrect as SSRIs do not provide immediate improvement in mood; rather, they require time to exert their therapeutic effects.
