The nurse is assessing a client who was recently diagnosed with Parkinson’s disease and is taking carbidopa-levodopa. The client is concerned that the medication is not working. Which intervention should the nurse implement first?

A) Ask if the client’s morning voids are dark colored: This intervention pertains to monitoring for potential adverse effects of carbidopa-levodopa, such as urine discoloration due to the breakdown of levodopa into dopamine. However, it does not directly address the client’s concern about the medication not working. While assessing for adverse effects is important, it may not provide immediate insight into the effectiveness of the medication in managing Parkinson’s disease symptoms. B) Evaluate the client for signs of dyskinesia: Dyskinesia refers to involuntary, abnormal movements that can occur as a side effect of long-term treatment with carbidopa-levodopa. While assessing for dyskinesia is essential during the management of Parkinson’s disease, it does not directly address the client’s immediate concern about the medication’s efficacy. It would be more appropriate to address the client’s primary concern first before assessing for potential adverse effects. C) Determine if the client is taking the medication before meals: The timing of medication administration, particularly with carbidopa-levodopa, can affect its absorption and effectiveness. Taking the medication with or without food can influence its onset of action and duration of effect. However, this intervention assumes that the client may not be taking the medication correctly, which may not necessarily be the case. It’s important to first clarify the client’s perception of the medication’s effectiveness before addressing administration instructions. D) Explore what the client means by the drug “is not working.” This option is correct. The nurse should prioritize exploring the client’s perception of the medication’s efficacy. Understanding the client’s specific concerns, such as which symptoms are not adequately controlled or how they define “not working,” can provide valuable information for further assessment and intervention. By actively listening to the client’s perspective, the nurse can collaboratively address any misconceptions, adjust the treatment plan if necessary, and provide education or reassurance accordingly.
