A client uses levodopa for treatment of Parkinson's disease. The client is now prescribed an adrenergic blocking agent. The nurse would assess the client for which of the following?
A) Decreased effect of levodopa
B) Increased effect of adrenergic blocker
C) Increased risk of levodopa toxicity
D) Decreased risk of psychotic behavior
Ans: A
Feedback:
When levodopa and adrenergic blockers are administered together, the effect of the levodopa is decreased. Therefore, the client's Parkinson's disease may not be controlled as effectively as before. The effect of the adrenergic blocker is not increased, nor is the risk for levodopa toxicity. The client is not experiencing psychotic behavior.
