Nursing Elites

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. When assessing a patient with generalized anxiety disorder (GAD), which symptom would the nurse most likely observe?

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

Correct answer: B

Rationale: Excessive worry is a characteristic feature of generalized anxiety disorder (GAD). Patients with GAD experience persistent and excessive worry about various aspects of their life, such as work, health, or family, even when there is little or no reason for concern. This chronic worrying can significantly impact their daily functioning and quality of life. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), hallucinations are more typical in conditions like schizophrenia, while compulsive behaviors are seen in obsessive-compulsive disorder (OCD). Therefore, in the context of GAD, excessive worry is the symptom that the nurse is most likely to observe.

3. 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 symptoms and contributing factors.
• D. The American Medical Association identifies 10 diagnostic labels that psychiatrists can choose from.

Correct answer: A

Rationale: Psychiatrists use pre-established criteria from the APA's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to determine which diagnosis to give a patient. The DSM-5 is a comprehensive manual published by the American Psychiatric Association (APA) that outlines specific criteria for diagnosing mental disorders. It aims to ensure accurate and consistent diagnosis and treatment. Choices B and D provide inaccurate information. Hospital policy does not dictate psychiatric diagnoses, and the American Medical Association does not provide diagnostic labels for mental disorders. Choice C, although mentioning the assessment of patients, does not highlight the specific criteria and guidelines provided by the DSM-5 that psychiatrists use to assign diagnoses.

4. During an assessment of a client with suspected substance use disorder, which of the following findings should the nurse expect? Select one that doesn't apply.

• A. Feelings of hopelessness
• B. Increased tolerance to the substance
• C. Withdrawal symptoms when not using the substance
• D. Unsuccessful attempts to cut down or control use

Correct answer: A

Rationale: In clients with substance use disorder, common findings include increased tolerance to the substance, withdrawal symptoms when not using it, and unsuccessful attempts to cut down or control use. Feelings of hopelessness are not typically a direct manifestation of substance use disorder. Instead, feelings of hopelessness may be associated with other mental health conditions or situational factors. Therefore, the correct answer is A. Choices B, C, and D are all expected findings in clients with substance use disorder.

5. Which characteristic in an adolescent female is sometimes associated with the prodromal phase of schizophrenia?

• A. Constantly afraid another student will steal her belongings.
• B. An unusual interest in numbers and specific topics.
• C. Demonstrates no interest in athletics or organized sports.
• D. Appears more comfortable among males.

Correct answer: B

Rationale: During the prodromal phase of schizophrenia, individuals may exhibit subtle changes in behavior or interests. An unusual interest in numbers and specific topics may be a sign of cognitive disturbances that can precede the onset of schizophrenia. While the other choices may also be observed in adolescents, an unusual interest in numbers and specific topics is more specifically linked to potential prodromal symptoms of schizophrenia.
