ATI Mental Health Practice A

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.

Correct Answer: C

Rationale: Cognitive-behavioral therapy (CBT) is considered the most effective therapeutic intervention for social anxiety disorder. CBT helps individuals identify and change negative thought patterns and behaviors associated with anxiety, leading to long-term symptom relief and improved coping strategies. Group therapy (choice A) can be beneficial as a complementary approach but may not be as effective as CBT for directly targeting individual cognitive and behavioral patterns. Behavioral rehearsal (choice B) is a technique used within CBT and not a standalone intervention for social anxiety disorder. Medication management (choice D) can be used as an adjunct to therapy in some cases but is not the first-line treatment for social anxiety disorder.

Correct Answer: C

Rationale: The correct answer is C: Dry mouth. Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs block acetylcholine receptors, leading to anticholinergic effects such as dry mouth, constipation, blurred vision, and urinary retention. It is important for the nurse to educate the patient about this side effect to promote awareness and provide appropriate management strategies, such as maintaining good oral hygiene and staying hydrated. Choice A, hypertension, is not a common side effect of TCAs. Choice B, diarrhea, is not a typical side effect of TCAs; in fact, TCAs are more likely to cause constipation. Choice D, weight loss, is less common with TCAs as they are more likely to cause weight gain.

Correct Answer: B

Rationale: Patients prescribed sertraline for major depressive disorder should be educated that it may take several weeks before experiencing the full therapeutic effects of the medication. This delay in onset of action is common with antidepressants like sertraline, and patients need to be aware of this to manage their expectations and continue with the treatment regimen. It's important for the patient to understand that consistent adherence to the prescribed dosage is crucial, even if the full effects are not immediately apparent. Choices A, C, and D are incorrect because taking the medication with food, avoiding grapefruit, and regular blood tests are not specific education points related to the expected timeframe for therapeutic effects of sertraline.

Correct Answer: A

Rationale: Cognitive-behavioral therapy (CBT) is widely recognized as the most effective treatment for phobias. CBT helps individuals identify and change negative thought patterns and behaviors associated with their phobias, leading to long-lasting improvement and symptom reduction. Unlike psychoanalysis, which focuses on exploring unconscious conflicts, CBT provides practical strategies to address phobias directly. Medication management may be used in conjunction with therapy but is not typically considered a standalone treatment for phobias. Group therapy can be beneficial for some individuals, but CBT is specifically tailored to target and alleviate phobia symptoms effectively.
