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. Which statement about the concept of psychoses is most accurate?

• A. Individuals experiencing psychoses are aware that their behaviors are maladaptive.
• B. Individuals experiencing psychoses experience little distress.
• C. Individuals experiencing psychoses are aware of experiencing psychological problems.
• D. Individuals experiencing psychoses are based in reality.

Correct answer: B

Rationale: The most accurate statement about psychoses is that individuals experiencing it often exhibit limited distress because they are not fully aware of their altered perception of reality. They may not recognize that their behaviors are maladaptive or acknowledge the presence of psychological issues. Choice A is incorrect because individuals with psychoses may not be aware that their behaviors are maladaptive. Choice C is incorrect because individuals with psychoses may not have insight into their psychological problems. Choice D is incorrect because individuals with psychoses often struggle to differentiate between reality and their altered perceptions.

3. A client is diagnosed with generalized anxiety disorder (GAD). Which of the following interventions should the nurse implement? Select one that does not apply.

• A. Encourage the client to express their feelings
• B. Teach the client relaxation techniques
• C. Promote regular physical activity
• D. Encourage the use of caffeine

Correct answer: D

Rationale: Interventions for a client with GAD should include encouraging the client to express their feelings, teaching relaxation techniques, and promoting regular physical activity. Caffeine should be avoided as it can exacerbate anxiety symptoms. Stimulants like caffeine can increase feelings of restlessness and nervousness, making it counterproductive in managing anxiety. Choices A, B, and C are appropriate interventions for managing generalized anxiety disorder by promoting emotional expression, relaxation, and physical well-being, respectively. Choice D, encouraging the use of caffeine, is incorrect as it can worsen anxiety symptoms rather than alleviate them.

4. Which response demonstrates accurate information that should be discussed with the female patient diagnosed with bipolar disorder and her support system? Select the incorrect one.

• A. Remember that alcohol and caffeine can trigger a relapse of your symptoms.
• B. Due to the risk of a manic episode, antidepressant therapy is never used with bipolar disorder.
• C. It's critical to inform your healthcare provider immediately if you are experiencing sleep disturbances.
• D. Is your family prepared to be actively involved in helping manage this disorder?

Correct answer: B

Rationale: In managing bipolar disorder, it is vital to educate the patient and their support system about triggers like alcohol and caffeine, the significance of good sleep, and the need for family involvement. However, the statement in choice B is incorrect. While antidepressants need to be carefully monitored in bipolar disorder, they can be used in conjunction with mood stabilizers to manage depression in some cases.

5. A patient with major depressive disorder is started on venlafaxine. Which class of antidepressant does this medication belong to?

• A. Selective serotonin reuptake inhibitors (SSRIs)
• B. Tricyclic antidepressants (TCAs)
• C. Monoamine oxidase inhibitors (MAOIs)
• D. Serotonin-norepinephrine reuptake inhibitors (SNRIs)

Correct answer: D

Rationale: Venlafaxine is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). SNRIs work by increasing the levels of both serotonin and norepinephrine in the brain, which helps alleviate symptoms of depression. This mechanism of action distinguishes SNRIs from other classes of antidepressants like SSRIs, TCAs, and MAOIs, making venlafaxine an effective choice for patients with major depressive disorder. Therefore, the correct answer is D. Choice A, SSRIs, primarily target serotonin reuptake only. Choice B, TCAs, work by inhibiting the reuptake of norepinephrine and serotonin, but they are not as selective as SNRIs. Choice C, MAOIs, inhibit the enzyme monoamine oxidase, leading to increased levels of various neurotransmitters, including serotonin and norepinephrine, but they are typically used as second- or third-line agents due to dietary restrictions and potential side effects.
