ATI Mental Health Practice A

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.

Correct Answer: B

Rationale: Buspirone is often chosen as a first-line treatment for generalized anxiety disorder (GAD) due to its efficacy and favorable side effect profile. Unlike benzodiazepines such as clonazepam (A), buspirone does not carry the risk of tolerance, dependence, or withdrawal symptoms, making it a preferred choice. While propranolol (C) and hydroxyzine (D) are sometimes used for anxiety, they are not typically considered first-line treatments for GAD.

Correct Answer: C

Rationale: The widow's symptoms align more closely with an adjustment disorder rather than major depression, normal grieving, or posttraumatic stress disorder. The widow's prolonged struggle in coping with the loss, characterized by emptiness, loss of self, difficulty envisioning the future, and anger towards her deceased husband, indicates an inability to adapt to the loss. These symptoms are indicative of an adjustment disorder, which typically arises in response to a significant life stressor and persists beyond what is considered a normal grieving process. Bereavement counseling can help the widow navigate her emotions and coping strategies during this challenging period.

Correct Answer: C

Rationale: Extrapyramidal symptoms, such as tremors and rigidity, are frequently observed as side effects of antipsychotic medications. These symptoms result from the medications' influence on dopamine receptors in the brain. Choice A, hyperactivity, is not a typical side effect of antipsychotic medications. Choice B, weight loss, is less common compared to weight gain. Choice D, insomnia, though possible, is not as prevalent as extrapyramidal symptoms in individuals taking antipsychotic medications.

Correct Answer: B

Rationale: Corrected Rationale: Sexual dysfunction is a commonly reported side effect of selective serotonin reuptake inhibitors (SSRIs). SSRIs can affect sexual function by causing issues such as decreased libido, delayed ejaculation, erectile dysfunction, or anorgasmia. Patients should be educated about these potential side effects when starting SSRIs to facilitate informed decision-making and appropriate management strategies. Incorrect Choices: A) Hypotension is not a common side effect of SSRIs. C) Increased appetite is not a common side effect of SSRIs. D) Tachycardia is not a common side effect of SSRIs.
