A 71-year-old patient has taken levodopa for Parkinson's disease for 2 weeks but reports no improvement in the symptoms. Select the nurse's best response.
 
  1. Stop the drug. If it has not been effective in 2 weeks, it is not likely to be beneficial.
  2. It may take several months for a response to occur. Continue the medication as prescribed.
  3. Double the dose to see if an effect will occur. Finding the correct dose takes many adjustments.
  4. Another agent will need to be added to the regimen now in order to manage your symptoms.

  a. Dopamine agonists are more effective than levodopa (Dopar).
  b. Dopamine agonists compete with dietary proteins in the intestines.
  c. Dopamine agonists are more likely to cause permanent and disabling dyskinesias.

Answer to Question 1

Correct Answer: 2

Answer to Question 2

ANS: D
The non-ergot derivatives cause fewer side effects than the ergot derivatives, because the non-ergot drugs are selective for dopamine receptors. Ergot derivatives interact with alpha-adrenergic and serotonergic receptors in addition to dopamine receptors.
Dopamine agonists are not more effective than levodopa.
Dopamine agonists do not compete with dietary proteins in the intestines.
Dopamine agonists are not more likely to cause permanent and disabling dyskinesias.
