When a husband accuses his wife of infidelity, which situation would indicate to the nurse the husband's use of the ego defense mechanism of projection?

Correct Answer: C

Rationale: Projection is a defense mechanism where one attributes their unacceptable feelings or impulses to another person. In this scenario, the husband, by admitting to having an affair with a coworker, is projecting his infidelity onto his wife, indicating the use of the projection defense mechanism. Choice A is incorrect as it describes a different behavior, not projection. Choice B does not demonstrate projection but rather avoidance or denial. Choice D shows displacement of aggression, not projection.

Correct Answer: B

Rationale: The correct answer is B. Mental health is defined as the successful adaptation to stressors in the internal and external environment. This includes having thoughts, feelings, and behaviors that are age-appropriate and congruent with cultural and societal norms. Mental health is not solely the absence of stressors or incongruence between thoughts, feelings, and behavior, nor is it a specific diagnostic category in the DSM-5. Choice A is incorrect because mental health is not just the absence of stressors but the ability to adapt to them. Choice C is wrong as mental health involves congruence, not incongruence, between thoughts, feelings, and behaviors. Choice D is inaccurate as mental health is a broader concept than a specific diagnostic category in the DSM-5.

Correct Answer: A

Rationale: The correct answer is A: Incomprehensibility and cultural relativity. Incomprehensibility and cultural relativity are the main criteria used across cultures to define behavior as mental illness. When behavior is incomprehensible and significantly deviates from cultural norms, it is more likely to be classified as a mental illness. Choices B, C, and D are incorrect. Strength of character, ethics, goal directedness, high energy, creativity, and good coping skills are typically associated with positive mental health rather than mental illness.

Correct Answer: D

Rationale: Repression is a defense mechanism where distressing thoughts, feelings, or memories are pushed out of conscious awareness to protect the individual from emotional pain. In this scenario, the woman's inability to recall the traumatic event of being raped at the age of 12 indicates repression in action. Choices A, B, and C do not represent repression. Choice A reflects procrastination, choice B suggests denial, and choice C indicates sublimation as the man is channeling his unhappiness into a constructive pursuit.

Correct Answer: B

Rationale: Defense mechanisms are employed by the ego in the face of threats to biological and psychological integrity to relieve mild to moderate anxiety. They act as protective devices for the ego, not the id or superego. The id represents primal instincts, while the superego is associated with moral standards. Defense mechanisms help individuals cope with stressors by redirecting focus and are often unconscious and self-deceptive.
