Correct Answer: B

Rationale: Mild anxiety sharpens the senses, increases the perceptual field, and results in heightened awareness of the environment, which enhances learning. As anxiety increases, attention span decreases, making learning more difficult. Therefore, mild anxiety is more conducive to effective instruction compared to moderate to severe anxiety, panic-level anxiety, or severe anxiety. Choice A is incorrect because moderate to severe anxiety impairs learning. Choice C is incorrect as panic-level anxiety can be overwhelming and hinder the learning process. Choice D is incorrect because severe anxiety typically leads to impaired attention span rather than enhancing it.

Correct Answer: B

Rationale: In caring for a client with borderline personality disorder, it is essential to set clear and consistent boundaries, use a firm, authoritative approach, and provide opportunities for the client to express feelings. Encouraging dependency can reinforce maladaptive behaviors, while avoiding discussing feelings can hinder therapeutic progress in addressing underlying issues. Building a sense of dependency may exacerbate the client's difficulties in developing autonomy and self-reliance, which are crucial for their progress and recovery. Therefore, encouraging dependency is not a recommended intervention in the plan of care for clients with borderline personality disorder.

Correct Answer: B

Rationale: Understanding mental health and mental illness as multidimensional and culturally defined is essential for healthcare professionals. Mental health varies across cultures and is influenced by various dimensions such as biological, psychological, social, and spiritual factors. Recognizing these differences helps in providing culturally competent care and understanding the diverse expressions of mental health and illness. Choice A is incorrect because mental health and mental illness are not rigid or solely based on religion. Choice C is incorrect because mental health and mental illness are not universally experienced in the same way and can change over time. Choice D is incorrect because mental health and mental illness are not unidimensional; they involve various factors and are not fixed in nature.

Correct Answer: D

Rationale: In this scenario, the nurse should interpret the client's behaviors as not indicative of mental illness. The client is experiencing normal feelings of sadness following the loss of a pet, and the fact that the client's appetite, sleep patterns, and daily routine remain unchanged suggests no functional impairment. It is essential to recognize that experiencing occasional feelings of sadness in response to a significant life event, such as the death of a pet, does not necessarily signify mental illness, especially when there is no significant impairment in daily functioning. Choices A, B, and C are incorrect because they incorrectly suggest that the client's behaviors indicate mental illness, which is not the case in this context.

Correct Answer: C

Rationale: The professional should identify that the student is using reaction formation as a defense mechanism. Reaction formation involves expressing opposite thoughts or behaviors to prevent undesirable thoughts from being expressed. In this scenario, the student's teasing and joking behavior towards the girl can be seen as a way to cover up or mask his true feelings or desires towards her. Displacement involves redirecting emotions from the original source to a substitute target; Projection involves attributing one's undesirable feelings to others; Sublimation involves channeling unacceptable impulses into socially acceptable activities. Therefore, in this case, the student's behavior aligns most closely with reaction formation.
