Question 1 of 5
The parent of an adolescent diagnosed with schizophrenia asks the nurse, My child™s doctor ordered a PET. What kind of test is that? Select the nurse™s best reply.
Correct Answer: B
Rationale: The correct answer is B because a PET scan, or positron-emission tomography, is a type of scan that uses a radioactive substance to show blood flow and brain activity. This is important in diagnosing conditions like schizophrenia. Choice A is incorrect because it describes an MRI, not a PET scan. Choice C describes an EEG, not a PET scan. Choice D describes a CT scan, not a PET scan.
Question 2 of 5
The therapeutic action of neurotransmitter inhibitors that block reuptake cause
Correct Answer: B
Rationale: The correct answer is B: increased concentration of the blocked neurotransmitter in the synaptic gap. When neurotransmitter inhibitors block reuptake, they prevent the reabsorption of neurotransmitters by the presynaptic neuron, leading to more neurotransmitters remaining in the synaptic gap. This increased concentration enhances neurotransmission and can help alleviate symptoms associated with neurotransmitter deficiencies. A: decreased concentration of the blocked neurotransmitter in the central nervous system - This is incorrect because blocking reuptake leads to an increased concentration of neurotransmitter in the synaptic gap, not a decrease in the central nervous system. C: destruction of receptor sites specific to the blocked neurotransmitter - This is incorrect because blocking reuptake does not affect receptor sites; it primarily impacts the reuptake process. D: limbic system stimulation - This is incorrect because blocking reuptake does not directly stimulate the limbic system; its primary effect is on neurotransmitter levels in the synaptic gap.
Question 3 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 4 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 5 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.
