Question 1 of 5
Which of the following drugs was most likely prescribed for the 45-year-old man with simple partial seizures who was already on lamotrigine therapy?
Correct Answer: D
Rationale: The drug that acts by opening a certain family of potassium channels on brain neurons is Perampanel. Given that the patient was already on lamotrigine and needed an additional drug to address his remaining symptoms, Perampanel would be the most likely choice for reducing the frequency of his attacks further.
Question 2 of 5
Which of the following actions most likely mediated the reduction in the patient's tremor?
Correct Answer: B
Rationale: The reduction in the patient's tremor most likely occurred due to the added benzotropine inhibiting the abnormally high cholinergic tone in the striatum. Cholinergic tone plays a significant role in the pathophysiology of Parkinson's disease, and by inhibiting this tone, the tremor can be controlled effectively. This action helps restore the balance between dopamine and acetylcholine, leading to improved motor symptoms in Parkinson's disease patients.
Question 3 of 5
Rivastigmine tachycardia likely due to the antiparkinson therapy. Which of the following actions most likely mediate the adverse effect reported by the patient?
Correct Answer: B
Rationale: The adverse effect of tachycardia in this case is likely mediated by the decreased acetylcholine release from cholinergic terminals. Rivastigmine is a cholinesterase inhibitor used to treat Alzheimer's disease, and blocking the breakdown of acetylcholine can lead to cholinergic overstimulation, resulting in tachycardia.
Question 4 of 5
A 64-year-old man with Parkinson disease complained of periods of complete immobility, followed by involuntary movements. The patient's current medications included levodopa/carbidopa. To reduce these rapid fluctuations, the neurologist reduced the daily dose of levodopa/carbidopa and added a drug. Which of the following drugs was most likely prescribed?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
Which of the following psychotropic drugs would be most appropriate to try at this stage for the 39-year-old man with chronic paranoid schizophrenia?
Correct Answer: D
Rationale: Clozapine is the most appropriate choice for this patient as he has not responded well to previous medications such as haloperidol, chlorpromazine, and risperidone. Clozapine is often used as a last resort for treatment-resistant schizophrenia and has shown to be effective in cases where other antipsychotics have failed. Additionally, the patient had a partial response to uphenazine, which indicates the need for a different medication approach, making clozapine the best option in this scenario.
