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. When assessing a client experiencing severe anxiety, which symptom should the nurse expect to observe?

• A. Restlessness
• B. Rapid heart rate
• C. Sweating
• D. Dry mouth

Correct answer: B

Rationale: When a client is experiencing severe anxiety, a rapid heart rate is a common physiological response. This increased heart rate is due to the body's fight-or-flight response, where adrenaline is released, causing the heart to beat faster. Monitoring the client's heart rate is crucial in assessing and managing their anxiety. Restlessness (choice A) can also be present in anxiety but is more of a behavioral manifestation rather than a physiological symptom. Sweating (choice C) can occur in anxiety, but it is not as specific or consistent as a rapid heart rate. Dry mouth (choice D) is associated with anxiety but is not as immediate or directly linked to the body's physiological response to stress as a rapid heart rate.

3. When an individual uses the defense mechanism of displacement after the boss openly disagrees with suggestions, what behavior would be expected from this individual?

• A. The individual assertively confronts the boss
• B. The individual leaves the staff meeting to work out in the gym
• C. The individual criticizes a coworker
• D. The individual takes the boss out to lunch

Correct answer: C

Rationale: The correct answer is C. The individual using the defense mechanism of displacement would criticize a coworker after being confronted by the boss. Displacement involves transferring feelings from one target to a neutral or less-threatening target, hence the individual criticizing a coworker instead of directly confronting the boss. Choices A, B, and D are incorrect. Choice A is incorrect because the individual is not likely to assertively confront the boss when using displacement. Choice B is incorrect as leaving the meeting to work out in the gym is not a typical response when displacement is used. Choice D is incorrect as taking the boss out to lunch does not align with the concept of displacement, which involves redirecting emotions onto another target.

4. Which of the following is a hallmark symptom of generalized anxiety disorder (GAD)?

• A. Flashbacks
• B. Excessive worry
• C. Hallucinations
• D. Compulsive behaviors

Correct answer: B

Rationale: Excessive worry is a hallmark symptom of generalized anxiety disorder (GAD). Individuals with GAD often experience persistent and excessive worry or anxiety about a variety of situations or activities, even when there is little or no reason to worry. This chronic worrying can significantly impact their daily functioning and quality of life, distinguishing it as a key feature of GAD. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), not GAD. Hallucinations are not typically seen in GAD but may be present in conditions like schizophrenia. Compulsive behaviors are characteristic of obsessive-compulsive disorder (OCD), not GAD.

5. A student finds that they come down with a sinus infection toward the end of every semester. When this occurs, which stage of stress is the student most likely experiencing?

• A. Alarm reaction stage
• B. Stage of resistance
• C. Stage of exhaustion
• D. Fight-or-flight stage

Correct answer: C

Rationale: The student is most likely experiencing the stage of exhaustion. In this stage, the body's exposure to stress has been prolonged, and adaptive energy has been depleted. As a result, diseases of adaptation, such as the recurrent sinus infection in this case, are more likely to occur. The alarm reaction stage is the initial stage of the stress response, where the body perceives a threat and activates the fight-or-flight response. The stage of resistance is when the body tries to adapt and cope with the stressor. The fight-or-flight response is the immediate reaction to a perceived threat, involving physiological changes to prepare the body to either fight the stressor or flee from it.
