1. Which neurotransmitter is primarily implicated in the development of schizophrenia?

• A. Serotonin
• B. Norepinephrine
• C. Dopamine
• D. Acetylcholine

Correct answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

2. Research conducted by Miller and Rahe in 1997 demonstrated a correlation between the effects of life changes and illness, leading to the development of the Recent Life Changes Questionnaire (RLCQ). Which principle most limits the effectiveness of this tool?

• A. Specific illnesses are not identified.
• B. The numerical values associated with specific life events are randomly assigned.
• C. Stress is viewed as only a physiological response.
• D. Personal perception of the event is excluded.

Correct answer: D

Rationale: The main limitation of the Recent Life Changes Questionnaire (RLCQ) is that it does not consider an individual's personal perception of a life event. As people may interpret events differently, their subjective perspective plays a crucial role in how they experience stress and its potential impact on their health. Ignoring personal perception limits the effectiveness of the tool as it fails to capture the variations in how people respond to life changes. Choices A, B, and C are not the main limitations of the RLCQ. Specific illnesses not being identified or numerical values being randomly assigned do not directly impact the personal perception of life events. Additionally, viewing stress as only a physiological response is not the primary limitation, as stress encompasses psychological and emotional components as well.

3. Which of the following interventions is inappropriate for a client experiencing a panic attack?

• A. Provide a well-lit environment.
• B. Encourage deep breathing.
• C. Move the client to a quiet environment.
• D. Administer prescribed antianxiety medication.

Correct answer: A

Rationale: During a panic attack, a well-lit environment might exacerbate the client's symptoms due to sensory overload. Therefore, it is inappropriate to provide a well-lit environment during a panic attack. Encouraging deep breathing, moving the client to a quiet environment, and administering prescribed antianxiety medication are appropriate interventions for managing a panic attack. These actions help create a calming atmosphere and address the physiological symptoms associated with panic attacks.

4. 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.

5. A client with obsessive-compulsive disorder (OCD) spends several hours each day washing her hands. Which intervention should the nurse implement?

• A. Encourage the client to wash her hands less frequently.
• B. Set a time limit for hand washing.
• C. Teach the client relaxation techniques.
• D. Discourage the client from washing her hands.

Correct answer: B

Rationale: Setting a time limit for hand washing is an appropriate intervention for a client with OCD who spends excessive time on this compulsive behavior. By setting a time limit, the nurse can help the client gradually reduce the compulsive behavior, promoting a more manageable approach to hand washing without completely discouraging it. Encouraging the client to wash her hands less frequently (Choice A) may not address the root of the issue and could lead to increased anxiety. Teaching relaxation techniques (Choice C) may be helpful for overall anxiety management but may not directly address the excessive hand washing behavior. Discouraging the client from washing her hands (Choice D) may increase anxiety and resistance, making it a less effective intervention.
