What criteria define a suspected stroke requiring rapid transport and stroke activation?

• A. Gradual onset of dizziness over minutes to hours
• B. Unconsciousness after head injury
• C. Severe chest pain with sweating
• D. Acute onset of focal neurological deficit (facial droop, arm drift, speech disturbance) within the therapeutic window.

Answer: (D)

The main idea being tested is recognizing an acute neurologic event that can be treated if caught early. A suspected stroke is defined by the sudden onset of focal neurologic deficits—such as facial droop, arm drift, or speech disturbance—that occur within the time frame where treatment can help (the therapeutic window). These signs point to a brain region being affected by a vascular event, so rapid transport and activation of a stroke protocol are essential to get timely evaluation and possible clot-busting therapy. Why this fits best: a sudden, focal neurologic deficit fits the pattern of a stroke and prompts immediate action to minimize brain damage. In contrast, gradual dizziness over minutes to hours isn’t typical of an acute stroke; unconsciousness after head injury points to trauma; and severe chest pain with sweating is more consistent with a cardiac event. The acute focal deficits within the time window are the hallmark that triggers rapid EMS stroke activation.
