1. Which neurotransmitter is primarily implicated in the development of schizophrenia?

• A. Serotonin
• B. Norepinephrine
• C. Dopamine
• D. Acetylcholine

Correct answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

2. In a patient with bipolar disorder, which symptom would indicate a manic episode?

• A. Excessive sleeping
• B. Low self-esteem
• C. Decreased need for sleep
• D. Anhedonia

Correct answer: C

Rationale: The correct answer is C: Decreased need for sleep. A decreased need for sleep is a hallmark symptom of a manic episode in bipolar disorder. During manic episodes, individuals may experience significantly reduced sleep without feeling tired, which can lead to increased energy levels, impulsivity, and other manic symptoms. Excessive sleeping (choice A) is more indicative of depression rather than mania. Low self-esteem (choice B) and anhedonia (choice D) are also more commonly associated with depressive episodes rather than manic episodes in bipolar disorder.

3. For a patient diagnosed with borderline personality disorder exhibiting self-harming behavior, which therapeutic approach is most appropriate?

• A. Dialectical behavior therapy
• B. Psychoanalysis
• C. Supportive therapy
• D. Pharmacotherapy

Correct answer: A

Rationale: The most appropriate therapeutic approach for a patient diagnosed with borderline personality disorder exhibiting self-harming behavior is dialectical behavior therapy (DBT). DBT is specifically designed to address the core symptoms of borderline personality disorder, including self-harming behaviors. It focuses on teaching patients skills to manage emotions, improve interpersonal relationships, and enhance distress tolerance. Psychoanalysis (Choice B) is not the most appropriate for immediate symptom management in this case. Supportive therapy (Choice C) may not provide the structured approach needed to address self-harming behaviors effectively. Pharmacotherapy (Choice D) may be used as an adjunct in some cases, but DBT is the frontline therapy for managing self-harming behaviors in borderline personality disorder.

4. A healthcare provider is assessing a client with generalized anxiety disorder (GAD). Which of the following findings should the healthcare provider expect? Select one that does not apply.

• A. Restlessness
• B. Fatigue
• C. Excessive worry
• D. Mania

Correct answer: D

Rationale: In generalized anxiety disorder (GAD), common symptoms include restlessness, fatigue, and excessive worry. These symptoms are typical in individuals with GAD due to persistent and excessive anxiety. Mania, on the other hand, is not a characteristic symptom of GAD. Mania is associated with bipolar disorder and is characterized by distinct features like elevated mood, grandiosity, and impulsivity. Therefore, the correct answer is 'D: Mania,' as it does not align with the expected findings in generalized anxiety disorder.

5. When caring for a patient with major depressive disorder prescribed an MAOI, what type of food should the nurse educate the patient to avoid?

• A. High-protein foods
• B. High-fiber foods
• C. Tyramine-rich foods
• D. Low-fat foods

Correct answer: C

Rationale: Patients prescribed MAOIs need to avoid consuming tyramine-rich foods as these can lead to hypertensive crises. Tyramine is found in various foods like aged cheeses, cured meats, some types of beer, and fermented products. Interactions between tyramine and MAOIs can result in severe hypertension, highlighting the importance of educating patients about dietary restrictions to ensure their safety. Choices A, B, and D are incorrect because high-protein foods, high-fiber foods, and low-fat foods do not pose a significant risk of hypertensive crises when taken with MAOIs. Therefore, the correct answer is C.
