The spouse of a client diagnosed with Parkinson's disease calls the clinic and tells the nurse the client is having involuntary jerky movements of the legs and arms and is confused. Which action should the clinic nurse implement first?

Rationale: A. Request that the client's spouse bring the client to the clinic as soon as possible: The client is showing signs of possible medication toxicity or a severe reaction, and immediate emergency intervention is warranted rather than a routine clinic visit. B. Advise the client's spouse to call an ambulance to take the client to the emergency department (ED): Involuntary jerky movements and new-onset confusion may indicate levodopa toxicity, drug interactions, or an acute neurological complication. These symptoms require rapid assessment and management in the emergency department. C. Ask the client's spouse to list all medications the client is currently taking: Obtaining a detailed medication list is necessary for identifying possible drug-induced causes of the symptoms. However, this information can be gathered later in the emergency setting. D. Determine how long the client has been diagnosed with Parkinson's disease: Knowing the disease duration provides background for understanding disease progression but does not address the urgent problem of acute confusion and abnormal movements.
