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: C

Rationale: Methylphenidate is a stimulant medication commonly prescribed to manage symptoms of attention-deficit/hyperactivity disorder (ADHD). It works by affecting certain chemicals in the brain to improve focus, attention span, and impulse control. Haloperidol, fluoxetine, and clozapine are not typically used as first-line treatments for ADHD. Haloperidol is an antipsychotic, fluoxetine is an antidepressant, and clozapine is an atypical antipsychotic, each with different mechanisms of action and primary indications.

Correct Answer: C

Rationale: In situations where a client is experiencing severe anxiety and struggles with independent problem-solving, it is essential for the nurse to work through the problem-solving process together with the client. By doing so, the nurse can provide support and guidance to help the client navigate through their challenges effectively. Choice A is not the most appropriate as just encouraging alternative coping mechanisms may not address the root of the problem. Choice B of completing the problem-solving process for the graduate does not promote independence or skill development. Choice D of encouraging the graduate to keep a journal may be helpful but does not directly address the need for assistance in problem-solving during heightened anxiety.

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: C

Rationale: The correct answer is C, Fluoxetine. Fluoxetine, a commonly prescribed antidepressant, is used to manage depressive episodes in bipolar disorder. It helps alleviate symptoms of depression by increasing the levels of serotonin in the brain, which can improve mood and reduce feelings of sadness and hopelessness. While mood stabilizers like lithium are often used in bipolar disorder, for depressive episodes, antidepressants like fluoxetine are preferred to address the specific symptoms associated with depression. Valproic acid is a mood stabilizer often used in bipolar disorder to manage manic episodes. Risperidone is an atypical antipsychotic that may be used in bipolar disorder to help control manic episodes or as an adjunctive treatment, but it is not a first-line medication for depressive episodes.
