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 10-year-old boy breaks his mother's vase while playing. When the mother asks who broke the vase, the little boy says that his sister did it. The little boy is exhibiting which defense mechanism?

• A. Projection
• B. Displacement
• C. Dissociation
• D. Sublimation

Correct answer: A

Rationale: Projection is a defense mechanism where one attributes their own unacceptable thoughts, feelings, or impulses onto another person. In this scenario, the little boy is projecting his actions onto his sister by falsely claiming she broke the vase. Displacement involves transferring emotions from the original source to a substitute target. Dissociation is a disconnection between thoughts, identity, consciousness, and memory. Sublimation is the redirection of unacceptable impulses into socially acceptable activities.

3. A patient presents in the Emergency Department immediately following a shooting incident in a school where she has been teaching. There is no evidence of physical injury, but she appears very hyperactive and talkative. Which of these symptoms manifested by the patient is an uncommon initial biological response to stress?

• A. Constricted pupils
• B. Watery eyes
• C. Palpitations
• D. Increased heart rate

Correct answer: A

Rationale: Increased lacrimal secretions, palpitations, and increased heart rate are common initial biological responses to stress. Constricted pupils are not typical in the initial response to stress and are more associated with the opposite response, the Rest and Digest system. Watery eyes, palpitations, and increased heart rate are indicative of the body's fight or flight response to stress. Unusual food cravings are not a typical biological response to stress.

4. Why is the DSM-5 useful in the practice of psychiatric nursing?

• A. It guides the nurse in making accurate and reliable medical diagnoses.
• B. It represents progress toward a more holistic view of mind and body.
• C. It provides a framework for interdisciplinary communication.
• D. It provides a template for nursing care plans.

Correct answer: A

Rationale: The DSM-5 is a crucial tool in psychiatric nursing as it guides nurses in making accurate and reliable medical diagnoses of mental health conditions. Using the DSM-5 ensures that diagnoses are standardized, improving the quality and precision of care for clients. While the DSM-5 also supports a holistic view, interdisciplinary communication, and care plan development, its primary role in psychiatric nursing is to assist clinicians in diagnosing mental health conditions accurately.

5. Which client action is an example of the defense mechanism of sublimation?

• A. A woman channels her energy into a new hobby after a breakup.
• B. A man redirects his anger from work into a workout routine.
• C. A student focuses on studying to avoid thinking about a recent argument.
• D. An athlete channels competitive impulses into a successful sports career.

Correct answer: B

Rationale: Sublimation is a defense mechanism where unacceptable impulses are redirected into socially acceptable activities. In this scenario, the man redirects his anger from work into a workout routine, which is a positive and constructive way of managing his emotions. Choices A, C, and D do not fully align with sublimation as they do not involve redirecting unacceptable impulses into socially acceptable outlets, unlike the man's action in choice B.
