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 patient with generalized anxiety disorder (GAD) is prescribed venlafaxine. The nurse should educate the patient about which potential side effect?

• A. Hypertension
• B. Hypotension
• C. Bradycardia
• D. Hyperglycemia

Correct answer: A

Rationale: The correct answer is A: Hypertension. Venlafaxine, an SNRI, can lead to hypertension as a side effect. This medication can cause an increase in blood pressure, particularly at higher doses. Educating the patient about this potential adverse effect is crucial to enhance awareness and monitoring for any signs or symptoms of elevated blood pressure. Choices B, C, and D are incorrect because venlafaxine is more likely to cause hypertension rather than hypotension, bradycardia, or hyperglycemia.

3. A healthcare provider is providing care for a patient with major depressive disorder who is prescribed a tricyclic antidepressant (TCA). Which common side effect should the healthcare provider educate the patient about?

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

Correct answer: C

Rationale: Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs can cause anticholinergic side effects, such as dry mouth, due to their mechanism of action. Educating the patient about dry mouth can help them stay informed and manage this common side effect effectively during treatment. Hypertension (Choice A) is not a common side effect of TCAs. Diarrhea (Choice B) is more commonly associated with selective serotonin reuptake inhibitors (SSRIs) than with TCAs. Weight loss (Choice D) is not a common side effect of TCAs; in fact, TCAs are more likely to cause weight gain.

4. How do psychiatrists determine which diagnosis to give a patient?

• A. Psychiatrists use pre-established criteria from the APA's Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
• B. Hospital policy dictates how psychiatrists diagnose mental disorders.
• C. Psychiatrists assess the patient and identify diagnoses based on the patient's unhealthy responses and contributing factors.
• D. The American Medical Association identifies 10 diagnostic labels that psychiatrists can choose from.

Correct answer: A

Rationale: The correct answer is A. Psychiatrists use the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) published by the American Psychiatric Association (APA) to determine diagnoses. The DSM-5 provides standardized criteria for the classification of mental disorders, ensuring accurate and reliable diagnosis and treatment. Choices B and D are inaccurate as hospital policy does not dictate psychiatric diagnoses, and the American Medical Association is not responsible for psychiatric diagnostic criteria. Choice C describes a more general approach to assessment and does not specifically address the standardized criteria used in psychiatric diagnosis.

5. Which should the individual recognize as an example of the defense mechanism of repression?

• A. A student aware of the need to study for tomorrow's test goes to a movie instead.
• B. A woman whose son was killed in Iraq does not believe the military report.
• C. A man who is unhappily married goes to school to become a marriage counselor.
• D. A woman was raped when she was 12 and no longer remembers the incident.

Correct answer: D

Rationale: Repression is a defense mechanism where distressing thoughts, feelings, or memories are pushed out of conscious awareness to protect the individual from emotional pain. In this scenario, the woman's inability to recall the traumatic event of being raped at the age of 12 indicates repression in action. Choices A, B, and C do not represent repression. Choice A reflects procrastination, choice B suggests denial, and choice C indicates sublimation as the man is channeling his unhappiness into a constructive pursuit.
