Question 2 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 3 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 4 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 5 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.
