Luis, a nursing student, is explaining to his patient the mechanism of action of selective serotonin reuptake inhibitors (SSRIs). What should he include?
SSRIs increase norepinephrine levels to elevate mood.
SSRIs inhibit serotonin production in the brain.
SSRIs decrease dopamine levels to improve mood.
SSRIs increase serotonin levels by preventing its reuptake into neurons.
The Correct Answer is D
Choice A reason: SSRIs do not increase norepinephrine levels; that is the action of SNRIs or other antidepressant classes.
Choice B reason: SSRIs do not inhibit serotonin production; instead, they work by blocking reuptake, leading to increased serotonin availability.
Choice C reason: SSRIs do not lower dopamine levels; this would worsen mood symptoms rather than improve them.
Choice D reason: SSRIs block serotonin reuptake in presynaptic neurons, which increases serotonin availability in the synaptic cleft and helps elevate mood.

Correct Answer is A
Explanation
Choice A reason: Administering 300 mg three times daily equals 900 mg total (300 mg × 3 = 900 mg).
Choice B reason: 300 mg represents only one dose, not the total for 24 hours.
Choice C reason: 1200 mg would be 300 mg four times daily, which is more than prescribed.
Choice D reason: 600 mg equals 300 mg twice daily, not the correct order.
Correct Answer is D
Explanation
Choice A reason:Physical activity is beneficial for overall health and can support mental well-being by reducing stress and improving mood. However, it does not replace the need for antipsychotic medication, which is specifically designed to manage symptoms of serious mental health conditions like schizophrenia or bipolar disorder by targeting neurotransmitter imbalances.
Choice B reason:Antipsychotics do not cure mental illnesses. They are effective in managing symptoms, such as hallucinations or delusions, by stabilizing brain chemistry, but they do not address the underlying cause of the condition or eliminate it entirely. Most mental illnesses require long-term management, not a cure.
Choice C reason:Taking antipsychotics at bedtime may help reduce certain side effects, like drowsiness, for some patients. However, it does not universally prevent all side effects, as these medications can cause a range of issues, including weight gain, movement disorders, or metabolic changes, regardless of the time of administration.
Choice D reason:Adherence to antipsychotic medication is critical because skipping doses can disrupt the therapeutic levels of the drug in the body, leading to a relapse of symptoms such as psychosis, mania, or severe mood disturbances. Consistent use helps maintain stability and prevent worsening of the condition, making this the most important point to convey.
