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. A nurse is reviewing prescriptions for a patient with major depression at the county clinic. Since the patient has a mild intellectual disability, the nurse would question which classification of antidepressant drugs:

• A. Selective serotonin reuptake inhibitors
• B. Monoamine oxidase inhibitors
• C. Serotonin and norepinephrine reuptake inhibitors
• D. All of the above

Correct answer: B

Rationale: Monoamine oxidase inhibitors are less suitable for patients with intellectual disabilities due to the need for dietary restrictions and close monitoring. These restrictions can be challenging for patients with mild intellectual disabilities to follow, making this drug class a concern for this patient population.

3. A patient with major depressive disorder is started on a tricyclic antidepressant (TCA). Which common side effect should the nurse educate the patient about?

• A. Hypertension
• B. Diarrhea
• C. Dry mouth
• D. Weight loss

Correct answer: C

Rationale: The correct answer is C: Dry mouth. Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs block acetylcholine receptors, leading to anticholinergic effects such as dry mouth, constipation, blurred vision, and urinary retention. It is important for the nurse to educate the patient about this side effect to promote awareness and provide appropriate management strategies, such as maintaining good oral hygiene and staying hydrated. Choice A, hypertension, is not a common side effect of TCAs. Choice B, diarrhea, is not a typical side effect of TCAs; in fact, TCAs are more likely to cause constipation. Choice D, weight loss, is less common with TCAs as they are more likely to cause weight gain.

4. A client diagnosed with schizophrenia is prescribed an antipsychotic medication. Which of the following side effects should the nurse not monitor for? Select all that apply.

• A. Tardive dyskinesia
• B. Neuroleptic malignant syndrome
• C. Orthostatic hypotension
• D. Hyperglycemia

Correct answer: A

Rationale: The nurse should not monitor for tardive dyskinesia as it is a potential long-term side effect of antipsychotic medications. However, the nurse should monitor for neuroleptic malignant syndrome, orthostatic hypotension, and hyperglycemia as these are common side effects associated with antipsychotic medications. Tardive dyskinesia is characterized by involuntary movements of the face, tongue, and extremities and may develop after prolonged use of antipsychotic drugs.

5. Which medication is commonly prescribed for the treatment of panic disorder?

• A. Haloperidol
• B. Clonazepam
• C. Lithium
• D. Fluoxetine

Correct answer: B

Rationale: Clonazepam, a benzodiazepine, is commonly prescribed for the treatment of panic disorder due to its anxiolytic properties. It helps reduce the frequency and intensity of panic attacks by acting on the central nervous system to produce a calming effect. Haloperidol is an antipsychotic medication, lithium is primarily used for bipolar disorder, and fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly used for depression and some anxiety disorders, but not as a first-line treatment for panic disorder.
