Nursing Elites

1. Which approach involves surgically implanting electrodes into specific areas of the brain to stimulate regions identified as underactive in depression?

• A. Transcranial magnetic stimulation
• B. Deep brain stimulation
• C. Vagus nerve stimulation
• D. Electroconvulsive therapy

Correct answer: B

Rationale: Deep brain stimulation is a treatment approach that involves the surgical implantation of electrodes into specific areas of the brain to stimulate regions identified as underactive in depression. This method aims to modulate brain activity and has shown effectiveness in treating certain cases of depression.

2. A client with bipolar disorder is experiencing a manic episode. Which of the following interventions should the nurse implement? Select one that does not apply.

• A. Provide a structured environment
• B. Encourage rest periods
• C. Limit setting on inappropriate behaviors
• D. Allow the client to engage in stimulating activities

Correct answer: D

Rationale: During a manic episode, it is essential to provide a structured environment to help the client maintain stability. Encouraging rest periods is crucial as excessive activity during mania can lead to exhaustion. Setting limits on inappropriate behaviors helps ensure the client's safety and the safety of others. Allowing the client to engage in stimulating activities can exacerbate manic symptoms by further increasing their energy levels and impulsivity. This can lead to a worsening of the manic episode and potentially risky behaviors. Therefore, allowing the client to engage in stimulating activities is not an appropriate intervention during a manic episode.

3. Which symptom should a healthcare provider identify as typical of the fight-or-flight response?

• A. Pupil dilation
• B. Increased heart rate
• C. Decreased salivation
• D. Decreased peristalsis

Correct answer: B

Rationale: The correct answer is B: Increased heart rate. During the fight-or-flight response, the sympathetic nervous system is activated, causing the release of epinephrine. This hormone triggers an increase in heart rate to supply more blood to the muscles for a rapid response. Pupil dilation occurs to enhance vision in preparation for quick reactions. On the other hand, salivation and peristalsis decrease as the body prioritizes functions necessary for immediate action rather than digestion-related activities. Therefore, choices A, C, and D are incorrect as they do not align with the typical physiological changes associated with the fight-or-flight response.

4. In a client with obsessive-compulsive disorder (OCD) undergoing cognitive-behavioral therapy, which outcome indicates that the therapy is effective?

• A. The client reports a decrease in the frequency of compulsive behaviors.
• B. The client reports a decrease in the intensity of obsessive thoughts.
• C. The client reports an improvement in overall mood.
• D. The client reports an improvement in sleep patterns.

Correct answer: A

Rationale: In clients with OCD undergoing cognitive-behavioral therapy, a decrease in the frequency of compulsive behaviors is a key indicator of treatment effectiveness. This reduction signifies progress in managing and controlling the compulsions associated with OCD, which is a primary goal of the therapy. Choices B, C, and D may also be positive outcomes of therapy, but the most critical aspect in treating OCD with cognitive-behavioral therapy is targeting and reducing the frequency of compulsive behaviors.

5. Adolescents often display fluctuations in mood along with undeveloped emotional regulation and poor tolerance for frustration. Emotional and behavioral control usually increases over the course of adolescence due to:

• A. Limited executive function
• B. Cerebellum maturation
• C. Cerebral stasis and hormonal changes
• D. A slight reduction in brain volume

Correct answer: B

Rationale: During adolescence, emotional and behavioral control typically improves as the cerebellum matures. The cerebellum plays a significant role in regulating emotions and behavior, contributing to the increased control seen in adolescents over time.
