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: B

Rationale: When a patient with PTSD is experiencing flashbacks, the most appropriate intervention is to help them reorient to the present. This intervention can assist in reducing the intensity of the flashback and providing a sense of safety for the patient. Choice A is incorrect because encouraging the patient to talk about the trauma during a flashback may exacerbate their distress. Choice C is incorrect as leaving the patient alone can increase their feelings of isolation and fear. Choice D is incorrect because reminding the patient that the flashback is not real may invalidate their experience and increase their sense of disconnection.

Correct Answer: C

Rationale: The correct answer is C, 'Sexual dysfunction.' Paroxetine, an SSRI commonly prescribed for OCD, can lead to sexual dysfunction as a side effect. Patients should be educated about this potential adverse effect to ensure they are aware and can seek appropriate management if needed. Choices A, B, and D are incorrect because insomnia, weight loss, and hypertension are not typically associated with paroxetine use as common side effects in patients with OCD.

Correct Answer: C

Rationale: Methylphenidate is a central nervous system stimulant often prescribed to manage symptoms of ADHD. It works by increasing the activity of certain neurotransmitters in the brain, helping to improve focus, attention, and impulse control in individuals with ADHD. Haloperidol, Sertraline, and Clozapine are not typically used as first-line treatments for ADHD. Haloperidol is an antipsychotic used in conditions like schizophrenia, Sertraline is an antidepressant primarily for mood disorders, and Clozapine is an atypical antipsychotic for treatment-resistant schizophrenia.

Correct Answer: C

Rationale: Drowsiness is a common side effect of benzodiazepines prescribed for anxiety. Benzodiazepines work by depressing the central nervous system, which can lead to drowsiness as a side effect. This sedative effect is often desired in the treatment of anxiety disorders, but individuals should be cautious when engaging in activities that require alertness, such as driving, while taking these medications. Insomnia, weight gain, and increased appetite are not typically associated with benzodiazepines; instead, drowsiness and sedation are more common side effects.
