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

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. A client has been prescribed diazepam (Valium) for the treatment of anxiety. Which of the following instructions should the nurse include in the discharge teaching?

Correct answer: A

Rationale: The correct instruction is to avoid drinking alcohol while taking diazepam (Valium) as it can potentiate the sedative effects and increase the risk of side effects such as drowsiness and dizziness. Taking the medication with food may help reduce stomach upset, but avoiding alcohol is crucial to ensure safe and effective use of diazepam. Choice B is partially correct, as taking the medication with food can indeed help with stomach upset, but it is not as crucial as avoiding alcohol. Choice C is incorrect because abruptly stopping diazepam can lead to withdrawal symptoms and should only be done under medical supervision. Choice D is incorrect as doubling the dose is dangerous and should never be done without healthcare provider approval.

3. A patient with generalized anxiety disorder (GAD) is prescribed escitalopram. The nurse should educate the patient that the full therapeutic effect of this medication may take:

Correct answer: D

Rationale: Escitalopram, an SSRI used in treating generalized anxiety disorder, typically takes 6-8 weeks to achieve its full therapeutic effect. While some improvement may be noticed earlier, the maximum benefit is usually experienced after this timeframe. Options A, B, and C are incorrect because they underestimate the time required for escitalopram to reach its full effectiveness. Educating patients about the realistic timeline for medication effectiveness is crucial in managing expectations and ensuring adherence to the prescribed treatment.

4. During a mental status examination, which of the following components should be included in the assessment? Select one that doesn't apply.

Correct answer: D

Rationale: During a mental status examination, key components to be assessed include the client's appearance and behavior, thought processes, mood and affect, and cognitive function. These components help in evaluating the client's mental health status. The statement about cultural distance and illness treatment is not a part of a mental status examination and is not relevant to the assessment of mental health. Choices A, B, and C are essential components of a mental status examination and contribute to a comprehensive evaluation of an individual's mental well-being.

5. In pediatric mental health, there is a lack of sufficient numbers of community-based resources and providers, and there are long waiting lists for services. This has resulted in: Select one that doesn't apply.

Correct answer: C

Rationale: The lack of resources in pediatric mental health leads to underserved populations, increased stress in the family unit, and premature termination of services. However, markedly increased funding does not align with the negative consequences of resource shortages; instead, it would be a potential solution to address the lack of resources and providers in pediatric mental health.
