Nursing Elites

1. A patient with major depressive disorder is started on venlafaxine. Which class of antidepressant does this medication belong to?

• A. Selective serotonin reuptake inhibitors (SSRIs)
• B. Tricyclic antidepressants (TCAs)
• C. Monoamine oxidase inhibitors (MAOIs)
• D. Serotonin-norepinephrine reuptake inhibitors (SNRIs)

Correct answer: D

Rationale: Venlafaxine is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). SNRIs work by increasing the levels of both serotonin and norepinephrine in the brain, which helps alleviate symptoms of depression. This mechanism of action distinguishes SNRIs from other classes of antidepressants like SSRIs, TCAs, and MAOIs, making venlafaxine an effective choice for patients with major depressive disorder. Therefore, the correct answer is D. Choice A, SSRIs, primarily target serotonin reuptake only. Choice B, TCAs, work by inhibiting the reuptake of norepinephrine and serotonin, but they are not as selective as SNRIs. Choice C, MAOIs, inhibit the enzyme monoamine oxidase, leading to increased levels of various neurotransmitters, including serotonin and norepinephrine, but they are typically used as second- or third-line agents due to dietary restrictions and potential side effects.

2. A client with obsessive-compulsive disorder (OCD) spends several hours each day washing her hands. Which intervention should the nurse implement?

• A. Encourage the client to wash her hands less frequently.
• B. Set a time limit for hand washing.
• C. Teach the client relaxation techniques.
• D. Discourage the client from washing her hands.

Correct answer: B

Rationale: Setting a time limit for hand washing is an appropriate intervention for a client with OCD who spends excessive time on this compulsive behavior. By setting a time limit, the nurse can help the client gradually reduce the compulsive behavior, promoting a more manageable approach to hand washing without completely discouraging it. Encouraging the client to wash her hands less frequently (Choice A) may not address the root of the issue and could lead to increased anxiety. Teaching relaxation techniques (Choice C) may be helpful for overall anxiety management but may not directly address the excessive hand washing behavior. Discouraging the client from washing her hands (Choice D) may increase anxiety and resistance, making it a less effective intervention.

3. A client with generalized anxiety disorder is prescribed buspirone. Which statement by the client indicates a need for further teaching?

• A. I can stop taking this medication once I feel less anxious.
• B. I should avoid drinking alcohol while taking this medication.
• C. It may take several weeks for this medication to take full effect.
• D. This medication can cause dependency.

Correct answer: A

Rationale: The correct answer is A because it indicates a misunderstanding about buspirone. Buspirone should not be abruptly stopped, and patients should follow the prescribed regimen consistently. Stopping the medication without proper guidance can lead to adverse effects or a return of anxiety symptoms. Choices B, C, and D demonstrate an understanding of important aspects of buspirone therapy: avoiding alcohol due to interactions, being patient for the medication to reach full effectiveness, and being aware of the potential for dependency with this medication.

4. In assessing a patient for signs of serotonin syndrome, which of the following symptoms would be consistent with this condition?

• A. Hypotension, bradycardia, hypothermia
• B. Hypertension, tachycardia, hyperthermia
• C. Hypotension, tachycardia, hypothermia
• D. Hypertension, bradycardia, hyperthermia

Correct answer: B

Rationale: Serotonin syndrome is characterized by a triad of symptoms: hypertension, tachycardia, and hyperthermia. Therefore, the correct answer is B. Hypotension, bradycardia, and hypothermia (choice A) are not typical findings in serotonin syndrome. Hypotension, tachycardia, and hypothermia (choice C) are also not consistent with serotonin syndrome. Hypertension, bradycardia, and hyperthermia (choice D) do not align with the characteristic symptoms of serotonin syndrome. Recognizing the key symptoms of serotonin syndrome is crucial for prompt identification and intervention to prevent serious complications.

5. A client has been taking lithium for several years with good symptom control. The client presents in the emergency department with blurred vision, tinnitus, and severe diarrhea. Which lithium level should the nurse correlate with these symptoms?

• A. 3.7
• B. 1.7
• C. 2.6
• D. 1.3

Correct answer: B

Rationale: Symptoms such as blurred vision, tinnitus, and severe diarrhea are indicative of lithium toxicity. A lithium level of 1.7 is within the toxic range. When clients present with these symptoms, it is crucial for the nurse to correlate them with elevated lithium levels to ensure timely intervention and prevent further complications.
