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. Which of the following interventions should not be implemented for a client with anorexia nervosa?

A. Monitor daily caloric intake and weight
B. Establish a structured eating plan
C. Encourage the client to exercise
D. Provide liquid supplements as prescribed

Correct answer: C

Rationale: Interventions for a client with anorexia nervosa should focus on monitoring daily caloric intake and weight, establishing a structured eating plan, providing liquid supplements as prescribed, and offering rewards for weight gain. Encouraging exercise is not recommended as it can worsen the condition by increasing energy expenditure and potentially reinforcing unhealthy behaviors associated with anorexia nervosa.

3. Which of the following is not a cultural aspect related to mental illness?

A. Local or cultural norms define pathological behavior.
B. The higher the social class, the greater the recognition of mental illness behaviors.
C. Psychiatrists typically see patients when the family can no longer deny the illness.
D. The greater the cultural distance from the mainstream of society, the greater the likelihood that the illness will be treated with sensitivity and compassion.

Correct answer: D

Rationale: The statement in option D is incorrect. The greater the cultural distance from the mainstream of society, the more likely there will be negative responses to mental illness. In such cases, coercive treatments and involuntary hospitalizations are more common, rather than sensitivity and compassion.

4. A female patient diagnosed with schizophrenia has been prescribed a first-generation antipsychotic medication. What information should the nurse provide to the patient regarding her signs and symptoms?

A. Her memory problems will likely decrease.
B. Depressive episodes should be less severe.
C. She will probably enjoy social interactions more.
D. She should experience a reduction in hallucinations.

Correct answer: D

Rationale: First-generation antipsychotic medications are effective in reducing hallucinations in patients with schizophrenia. These medications primarily target positive symptoms such as hallucinations and delusions. Therefore, the nurse should inform the patient that she should experience a reduction in hallucinations with the prescribed first-generation antipsychotic medication.

5. Which should the healthcare provider recognize as a DSM-5 disorder?

A. Obesity
B. Generalized anxiety disorder
C. Hypertension
D. Grief

Correct answer: B

Rationale: The DSM-5 categorizes mental health disorders for diagnostic purposes. Generalized anxiety disorder is one of the disorders listed in the DSM-5, characterized by persistent and excessive worry about various events or activities. This disorder falls under the category of anxiety disorders, which also include panic disorder, phobias, and others. Choices A, C, and D are not DSM-5 disorders. Obesity and hypertension are medical conditions, while grief, though a significant emotional response, is not classified as a mental health disorder in the DSM-5.
