Question 1 of 5
A 62-year-old man complained to his physician of facial grimacing, lip smacking, and rocking of the trunk that occurred 1 to 2 hours after taking his prescribed medication. The man, who suffered from Parkinson's disease, had been receiving an antiparkinson drug for 3 years. Which of the following drugs most likely caused the adverse effects reported by the man?
Correct Answer: B
Rationale: The adverse effects of facial grimacing, lip smacking, and rocking of the trunk are symptoms of levodopa-induced dyskinesia, which is a common side effect of long-term levodopa use in Parkinson's disease. This adverse effect is known as levodopa-induced dyskinesia, which is characterized by involuntary movements like grimacing and lip smacking. Therefore, the correct answer is B (Levodopa).
Question 2 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 3 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 4 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.
Question 5 of 5
Which of the following drugs would be most appropriate to suppress choreic movements and agitated behavior in the 35-year-old man with Huntington chorea?
Correct Answer: F
Rationale: Haloperidol is the most appropriate choice for this patient with Huntington chorea as it is a typical antipsychotic that can help suppress choreic movements and agitated behavior. Haloperidol is commonly used to manage the motor symptoms associated with Huntington's disease, making it the best option in this case. Additionally, the patient's symptoms of persecutory delusions and auditory hallucinations may also be alleviated by haloperidol, further supporting its use in this scenario.
