After seeking care for tremors that have become increasingly severe in recent months, a 71-year-old man has been diagnosed with Parkinson disease and will soon begin treatment with carbidopa-levodopa.
 
  Which of the following statements indicates that the patient has an accurate understanding of his new medication?
  A) I'll have to learn how to modify each dose of carbidopa-levodopa based on how bad my symptoms are that day.
  B) I've read that carbidopa-levodopa is quite short-acting so I'll have to take it several times a day.
  C) I'll make sure to stop taking my other medications so that my carbidopa-levodopa doesn't interact with them.
  D) I've heard that it can take up to a year for carbidopa-levodopa to cure someone of Parkinson disease.
