Answer to Question 1

B
Duloxetine can cause elevation of serum transaminases, indicating liver disease. Patients with existing liver disease or alcohol abuse should not receive this drug. This side effect is not likely with desvenlafaxine or venlafaxine. Escitalopram is an SSRI.

Answer to Question 2

D
Patients beginning therapy with levodopa/carbidopa should expect therapeutic effects to occur after several months of treatment. Levodopa is so effective that a diagnosis of PD should be questioned if the patient fails to respond in this time frame. Adding a dopamine agonist is not indicated. The on-off phenomenon occurs when therapeutic effects are present. Increasing the dose of levodopa/carbidopa is not indicated.
