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. How do psychiatrists determine which diagnosis to give a patient?

• A. Psychiatrists use pre-established criteria from the APA's Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
• B. Hospital policy dictates how psychiatrists diagnose mental disorders.
• C. Psychiatrists assess the patient and identify diagnoses based on the patient's unhealthy responses and contributing factors.
• D. The American Medical Association identifies 10 diagnostic labels that psychiatrists can choose from.

Correct answer: A

Rationale: The correct answer is A. Psychiatrists use the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published by the American Psychiatric Association (APA) to determine diagnoses. The DSM-5 provides standardized criteria for the classification of mental disorders, ensuring accurate and reliable diagnosis and treatment. Choices B and D are inaccurate as hospital policy does not dictate psychiatric diagnoses, and the American Medical Association is not responsible for psychiatric diagnostic criteria. Choice C describes a more general approach to assessment and does not specifically address the standardized criteria used in psychiatric diagnosis.

3. A psychiatric nurse observes that a client diagnosed with schizophrenia is pacing up and down the corridor. The client is muttering to himself, and his hands are trembling. Which of the following actions should the nurse take first?

• A. Ask the client if he is hearing voices.
• B. Offer the client a PRN medication for anxiety.
• C. Encourage the client to participate in a relaxation exercise.
• D. Remove the client to a quieter environment.

Correct answer: D

Rationale: The first action the nurse should take is to remove the client to a quieter environment. This intervention aims to reduce stimuli that may be contributing to the client's agitation and help create a calmer and more supportive setting for the client. Choices A, B, and C are not the priority in this situation as addressing the environmental factors should come first before exploring symptoms, offering medication, or engaging in relaxation exercises.

4. According to Maslow's hierarchy of needs, which situation on an inpatient psychiatric unit would require priority intervention by a nurse?

• A. A client rudely complaining about limited visiting hours
• B. A client exhibiting aggressive behavior toward another client
• C. A client stating that no one cares
• D. A client verbalizing feelings of failure

Correct answer: B

Rationale: The correct answer is B. According to Maslow's hierarchy of needs, safety needs are considered fundamental and must be addressed before higher-level needs. When a client exhibits aggressive behavior toward another client, it poses an immediate threat to safety and requires priority intervention by the nurse to ensure the well-being of all individuals involved. Clients who are rude in their complaints (Choice A), express feelings of failure (Choice D), or state that no one cares (Choice C) are addressing higher-level needs related to social interactions, esteem, and self-actualization, respectively, which can be addressed once safety needs are secured.

5. Which of the following is a hallmark symptom of generalized anxiety disorder (GAD)?

• A. Flashbacks
• B. Excessive worry
• C. Hallucinations
• D. Compulsive behaviors

Correct answer: B

Rationale: Excessive worry is a hallmark symptom of generalized anxiety disorder (GAD). Individuals with GAD often experience persistent and excessive worry or anxiety about a variety of situations or activities, even when there is little or no reason to worry. This chronic worrying can significantly impact their daily functioning and quality of life, distinguishing it as a key feature of GAD. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), not GAD. Hallucinations are not typically seen in GAD but may be present in conditions like schizophrenia. Compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD), not GAD.
