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.
