1. A patient with major depressive disorder is started on venlafaxine. Which class of antidepressant does this medication belong to?

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 nurse is providing education to a client diagnosed with generalized anxiety disorder (GAD). Which of the following statements by the client indicates a need for further teaching? Select one that does not apply.

Correct answer: B

Rationale: Statements indicating a need for further teaching include stopping medication once feeling better and believing that medication will always be needed. Medication should be continued as prescribed, and the need for it should be regularly re-evaluated by a healthcare provider.

3. How do epidemiological studies contribute to improvements in care for individuals with mental disorders?

Correct answer: B

Rationale: Epidemiological studies play a crucial role in identifying risk factors associated with the development of mental disorders. By pinpointing these risk factors, healthcare providers can implement preventive measures and develop more effective treatments, ultimately leading to improved care for individuals with mental disorders.

4. A client with major depressive disorder is prescribed an antidepressant. Which of the following instructions should the nurse exclude from the teaching?

Correct answer: C

Rationale: The nurse should not include the instruction to discourage the client from washing her hands in the teaching for a client prescribed an antidepressant. This instruction is not relevant to the medication regimen. Instead, the nurse should educate the client that it may take several weeks for the medication to take effect, to avoid alcohol, not to discontinue the medication abruptly, and that there may be an increase in energy before mood improves. Regular blood tests are not typically required for most antidepressants.

5. Which statement about the concept of neuroses is most accurate?

Correct answer: B

Rationale: Neurosis involves feelings of distress and anxiety, but individuals experiencing neurosis are usually aware of their distress and its causes. They may recognize that their behaviors are maladaptive and are generally in contact with reality. The accurate statement about neurosis is that an individual feels helpless to change their situation. Choice A is incorrect because individuals with neurosis are usually aware of their distress. Choice C is incorrect because while individuals may be aware of psychological causes, it is not the defining characteristic of neurosis. Choice D is incorrect because a loss of contact with reality is more characteristic of psychosis, not neurosis.
