A patient is prescribed Risperidone 2 mg every morning. If Risperidone 0.5 mg tablets are available, how many tablets should be administered each morning?
2 tablets
1 tablet
4 tablets
3 tablets
The Correct Answer is C
Choice A reason: Two tablets (1 mg) underdose the prescribed 2 mg. Risperidone, an antipsychotic, balances dopamine and serotonin for schizophrenia or bipolar disorder. Scientifically, insufficient dosing fails to stabilize neural activity, risking symptom persistence, like hallucinations, due to inadequate receptor modulation, compromising mental health treatment efficacy.
Choice B reason: One tablet (0.5 mg) significantly underdoses the 2 mg requirement. Risperidone’s therapeutic effect relies on adequate dopamine antagonism. Scientifically, subtherapeutic levels leave psychotic symptoms uncontrolled, as insufficient receptor blockade fails to reduce neural hyperactivity, increasing risks of agitation or psychosis relapse.
Choice C reason: Four tablets (2 mg) match the prescribed dose, ensuring therapeutic dopamine and serotonin modulation. Scientifically, accurate Risperidone dosing stabilizes neural activity, reducing psychotic symptoms like hallucinations. This optimizes antipsychotic efficacy, preventing symptom exacerbation while avoiding side effects from overdosing, supporting mental health stability.
Choice D reason: Three tablets (1.5 mg) underdose the required 2 mg, reducing efficacy. Risperidone’s antipsychotic effects depend on precise receptor antagonism. Scientifically, inadequate dosing fails to control dopamine-driven symptoms, risking psychosis or agitation, as neural hyperactivity persists, compromising treatment outcomes for schizophrenia or bipolar disorder.

Correct Answer is B
Explanation
Choice A reason: Providing a meal and discharging ignores neglect’s broader impact. Malnutrition and neglect elevate cortisol, risking developmental delays. Scientifically, addressing only immediate nutrition fails to protect the child from ongoing harm, as unaddressed abuse can exacerbate psychological trauma and physical health deficits, delaying recovery.
Choice B reason: Reporting to child protective services while meeting immediate needs ensures safety and addresses neglect. Malnutrition disrupts metabolic and cognitive function, while abuse elevates stress hormones. Scientifically, prompt reporting triggers protective interventions, stabilizing the child’s neurobiological stress responses and supporting physical and psychological recovery.
Choice C reason: Calling parents risks escalating harm, as they may be the neglect source. Scientifically, premature contact can increase the child’s stress, elevating cortisol and worsening trauma-related symptoms. This delays protective interventions, leaving the child vulnerable to ongoing neglect and its neurobiological consequences, like developmental delays.
Choice D reason: Waiting for further evidence delays protection, risking ongoing harm. Neglect’s impact, like malnutrition, disrupts brain development and increases cortisol. Scientifically, delaying action fails to address trauma’s neurobiological effects, allowing continued physical and psychological harm, compromising the child’s safety and long-term well-being.
Correct Answer is C
Explanation
Choice A reason: One tablet (25 mg) underdoses the prescribed 50 mg per dose. Quetiapine, an antipsychotic, modulates dopamine and serotonin for conditions like schizophrenia or bipolar disorder. Scientifically, insufficient dosing fails to stabilize neural activity, risking persistent psychotic symptoms, as inadequate receptor blockade does not address neurotransmitter imbalances, compromising treatment efficacy.
Choice B reason: Four tablets (100 mg) per dose significantly exceed the prescribed 50 mg, risking toxicity. Quetiapine overdosing can cause sedation, hypotension, or cardiac arrhythmias due to excessive dopamine and serotonin receptor antagonism. Scientifically, precise dosing is critical to avoid adverse effects while ensuring therapeutic efficacy for mental health stabilization.
Choice C reason: Two tablets (50 mg) match the prescribed dose, ensuring therapeutic dopamine and serotonin modulation. Scientifically, accurate Quetiapine dosing stabilizes neural activity, effectively managing psychotic or mood symptoms. This prevents symptom exacerbation or toxicity, supporting mental health recovery by optimizing receptor antagonism without adverse effects.
Choice D reason: Three tablets (75 mg) per dose overdose the patient, increasing side effect risks. Quetiapine’s effects on dopamine and serotonin can lead to excessive sedation or cardiovascular issues if overdosed. Scientifically, maintaining therapeutic levels prevents neurological complications, ensuring safe and effective treatment for psychiatric conditions.
