A patient is prescribed 100 mg of Clozapine daily. The available tablet strength is 25 mg. How many tablets should the nurse administer?
4 tablets
3 tablets
5 tablets
2 tablets
The Correct Answer is A
Choice A reason: Four tablets (100 mg) match the prescribed Clozapine dose. This antipsychotic stabilizes dopamine and serotonin in schizophrenia. Scientifically, accurate dosing ensures therapeutic receptor antagonism, controlling psychotic symptoms without toxicity, supporting mental health stability by addressing neural hyperactivity effectively in treatment.
Choice B reason: Three tablets (75 mg) underdose the prescribed 100 mg. Clozapine’s efficacy relies on sufficient receptor blockade. Scientifically, subtherapeutic dosing fails to control dopamine-driven symptoms, risking persistent psychosis or hallucinations, as inadequate levels don’t stabilize neural activity, compromising schizophrenia management.
Choice C reason: Five tablets (125 mg) exceed the prescribed dose, risking toxicity. Clozapine overdosing can cause agranulocytosis or seizures due to excessive receptor antagonism. Scientifically, precise dosing prevents severe side effects, ensuring safe treatment by maintaining therapeutic levels for effective schizophrenia symptom control.
Choice D reason: Two tablets (50 mg) significantly underdose the required 100 mg. Scientifically, insufficient Clozapine fails to modulate dopamine and serotonin, risking persistent psychotic symptoms. This compromises treatment efficacy, as subtherapeutic levels don’t address neural hyperactivity, delaying recovery in schizophrenia management.

Correct Answer is B
Explanation
Choice A reason: Increasing therapy frequency may overwhelm without assessing frustration’s cause. Substance use disorder involves dopamine-driven reward issues. Scientifically, unguided escalation risks disengagement, as unaddressed psychological barriers, like stress or low motivation, may exacerbate relapse risk, delaying effective recovery interventions.
Choice B reason: Assessing the client’s perspective identifies barriers to progress, like stress or unrealistic expectations. Scientifically, this evaluates dopamine dysregulation and emotional triggers, guiding tailored interventions. Engaging the prefrontal cortex enhances motivation, stabilizing recovery by addressing specific psychological and neurobiological challenges in substance use disorder.
Choice C reason: Focusing on positives may dismiss valid frustrations, reducing trust. Scientifically, ignoring negative emotions risks suppressing dopamine-driven motivation, delaying recovery. Addressing concerns directly engages cognitive processing, supporting resilience and preventing relapse by tackling addiction’s psychological and neurobiological underpinnings effectively.
Choice D reason: Reassuring about setbacks is supportive but doesn’t address specific frustrations. Scientifically, untargeted reassurance fails to engage prefrontal cortex decision-making, risking persistent dopamine-driven cravings. Assessing concerns first ensures tailored interventions, stabilizing recovery by addressing psychological barriers in substance use disorder management.
Correct Answer is C
Explanation
Choice A reason: Reassuring and scheduling follow-up delays action on potential abuse. Unexplained bruises suggest trauma, potentially elevating cortisol and stress responses. Scientifically, delaying intervention risks ongoing harm, as unaddressed abuse can lead to psychological disorders like PTSD, compromising the child’s safety and mental health.
Choice B reason: Documenting and discharging ignores immediate safety concerns. Bruises and discomfort may indicate abuse, triggering stress-related physiological changes. Scientifically, failing to investigate risks further trauma, as unaddressed abuse can exacerbate anxiety or depression, leaving the child vulnerable to ongoing harm without protective intervention.
Choice C reason: Contacting child protective services and further assessing ensures immediate safety. Bruises and discomfort suggest abuse, impacting stress hormones like cortisol. Scientifically, prompt reporting and evaluation protect the child from further trauma, addressing neurobiological stress responses and preventing long-term psychological harm, prioritizing child welfare.
Choice D reason: Confronting the child risks re-traumatization, as children may fear disclosure. Scientifically, direct confrontation can elevate stress responses, increasing cortisol and amygdala activity, potentially worsening trauma-related symptoms. A sensitive, professional assessment is needed to confirm abuse without causing psychological harm or deterring honest communication.
