The nurse is caring for a client who arrives at the emergency department with reports of experiencing dizziness and difficulty walking to the bathroom. The nurse observes right-sided weakness and sluggish enunciation of speech. The nurse should immediately take which action?

A. Placing an indwelling urinary catheter and measuring strict intake and output may be necessary for comprehensive assessment and management but is not the priority action in this situation, which suggests a possible stroke. B. Keeping the bed in the lowest position and initiating seizure and fall precautions are important for safety, but the client's symptoms are suggestive of a stroke, and immediate evaluation and potential treatment are needed. C. Starting two large-bore IV catheters and reviewing inclusion criteria for IV fibrinolytic therapy is the priority action. The client's symptoms, including right-sided weakness and sluggish speech, suggest a potential ischemic stroke. IV fibrinolytic therapy (e.g., tissue plasminogen activator) is time-sensitive and may be indicated for eligible patients with acute ischemic stroke. D. Maintaining elevated positioning of the dependent joints on the affected side is not the priority action in this situation. Immediate assessment and potential treatment for a suspected stroke are needed.
