Question 1 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 2 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 3 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 4 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.
Question 5 of 5
Consider these medications: carbamazepine, lamotrigine, gabapentin. Which medication below also belongs to this group?
Correct Answer: B
Rationale: Correct Answer: B (Valproate) Rationale: 1. Valproate is an antiepileptic drug, like carbamazepine, lamotrigine, and gabapentin. 2. All medications listed are commonly used to treat epilepsy and various seizure disorders. 3. Galantamine, Buspirone, and Tacrine are not antiepileptic drugs and do not belong to the same group. 4. Valproate shares similar mechanisms of action and indications with the medications in the group. Summary: Valproate is the correct answer as it shares the same therapeutic class and indications as carbamazepine, lamotrigine, and gabapentin. Galantamine, Buspirone, and Tacrine do not belong to this group and are used for different purposes.
