Question 1 of 5
The nurse administers a medication that potentiates the action of ã-aminobutyric acid (GABA). Which effect would be expected?
Correct Answer: A
Rationale: The correct answer is A: Reduced anxiety. GABA is an inhibitory neurotransmitter that helps calm and relax the nervous system. By potentiating its action, the medication would increase GABA's calming effects, leading to reduced anxiety. Choice B (Improved memory) is incorrect as GABA's role is not directly related to memory enhancement. Choice C (More organized thinking) is incorrect as GABA primarily affects mood and anxiety, not cognitive processes. Choice D (Fewer sensory perceptual alterations) is incorrect as GABA modulation would not directly impact sensory perceptions.
Question 2 of 5
A patient is hospitalized for severe major depressive disorder. Of the medications listed below, the nurse can expect to provide the patient with teaching about
Correct Answer: C
Rationale: Rationale: 1. Severe major depressive disorder is typically treated with antidepressants, making sertraline (C) the appropriate choice. 2. Chlordiazepoxide (A) is a benzodiazepine used for anxiety, not depression. 3. Clozapine (B) is an atypical antipsychotic for schizophrenia, not first-line for depression. 4. Tacrine (D) is used for Alzheimer's disease, not depression.
Question 3 of 5
A patient tells the nurse, My doctor prescribed paroxetine for my depression. I assume I™ll have side effects like I had when I was taking imipramine. The nurse™s reply should be based on the knowledge that paroxetine is a(n)
Correct Answer: D
Rationale: The correct answer is D: SSRI. Paroxetine is a selective serotonin reuptake inhibitor (SSRI), which works by increasing serotonin levels in the brain. This is different from imipramine, a tricyclic antidepressant. SSRIs like paroxetine are known for having different side effect profiles compared to tricyclic antidepressants. Selective norepinephrine reuptake inhibitors and MAO inhibitors are different classes of antidepressants with distinct mechanisms of action compared to paroxetine. Therefore, the nurse should inform the patient that paroxetine is an SSRI and may have different side effects compared to imipramine.
Question 4 of 5
A nurse instructs a patient taking a drug that inhibits MAO to avoid certain foods and drugs because of the risk of
Correct Answer: C
Rationale: The correct answer is C: hypertensive crisis. MAO inhibitors inhibit the breakdown of neurotransmitters like serotonin, leading to increased blood pressure. Foods containing tyramine can trigger a hypertensive crisis due to excessive release of norepinephrine. Choices A, B, and D are incorrect as they are not directly associated with MAO inhibitors. Cardiac dysrhythmia is not a common side effect of MAO inhibitors. Hypotensive shock is unlikely as MAO inhibitors typically raise blood pressure. Hypoglycemia is not a common risk associated with MAO inhibitors.
Question 5 of 5
A drug blocks the attachment of norepinephrine to ï¡1 receptors. The patient may experience
Correct Answer: B
Rationale: The correct answer is B: orthostatic hypotension. Blocking norepinephrine from binding to α1 receptors would prevent vasoconstriction, leading to decreased blood pressure upon standing (orthostatic hypotension). Hypertensive crisis (A) would be more likely if norepinephrine was acting on α1 receptors causing vasoconstriction. Severe appetite disturbance (C) and an increase in psychotic symptoms (D) are not directly related to blocking norepinephrine from binding to α1 receptors.
