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. In treating social anxiety disorder, which medication is commonly prescribed to patients with this condition?

• A. Methylphenidate
• B. Sertraline
• C. Lithium
• D. Haloperidol

Correct answer: B

Rationale: Sertraline is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat social anxiety disorder. SSRIs are a first-line pharmacological treatment for social anxiety disorder due to their effectiveness in reducing anxiety symptoms by increasing serotonin levels in the brain, which helps regulate mood and emotions. Methylphenidate is a stimulant primarily used in attention deficit hyperactivity disorder (ADHD) but not in social anxiety disorder. Lithium is typically used in bipolar disorder, while haloperidol is an antipsychotic medication more commonly used in conditions like schizophrenia. Therefore, the correct choice for treating social anxiety disorder is Sertraline (B).

3. Substance abuse is often present in individuals diagnosed with bipolar disorder. Laura, a 28-year-old with a bipolar disorder diagnosis, chooses to drink alcohol instead of taking her prescribed medications. The nurse caring for this patient recognizes that:

• A. Anxiety may be present.
• B. Alcohol ingestion is a form of self-medication.
• C. The patient is lacking a sufficient number of neurotransmitters.
• D. The patient is using alcohol as a coping mechanism.

Correct answer: B

Rationale: Individuals with bipolar disorder may turn to alcohol as a form of self-medication to cope with their symptoms. This behavior is often seen as an attempt to manage mood swings and alleviate distress. It is important for healthcare providers to address and manage substance abuse issues in patients with bipolar disorder to ensure proper treatment and overall well-being.

4. 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.

5. In addition to antianxiety agents, which classification of drugs is commonly prescribed to treat anxiety and anxiety disorders?

• A. Antipsychotics
• B. Mood stabilizers
• C. Antidepressants
• D. Cholinesterase inhibitors

Correct answer: C

Rationale: Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are frequently used in the treatment of anxiety disorders. These medications help alleviate symptoms by affecting neurotransmitters in the brain associated with mood regulation and anxiety.
