What is an essential consideration when a passenger is having a possible stroke regarding EMS?

• A. Blood type
• B. Favorite color
• C. Time of onset and last known well
• D. Age

Answer: (C)

Time of onset and last known well are the key factors in EMS stroke care because treating stroke effectively hinges on how soon it began. Knowing the exact onset time or the last moment the person was known to be without symptoms helps determine whether the patient still falls within the window for clot-busting therapies and guides rapid transport to a facility able to perform imaging and definitive treatment. If the person woke up with symptoms, the last known well time serves as the reference for the treatment window. Other details like blood type, age, or personal preferences don’t drive the immediate prehospital stroke decisions.
