What are the FAST stroke signs and why is rapid EMS activation critical?

• A. Face droop, Arm weakness, Speech difficulty; Time to call EMS immediately for potential thrombolytic therapy window
• B. Face droop alone
• C. Arm weakness alone
• D. Slurred speech with no facial droop

Answer: (A)

The main idea being tested is recognizing FAST stroke signs and understanding why quick EMS action matters. FAST stands for facial droop, arm weakness, and speech difficulty—three indicators that a sudden, likely stroke is occurring due to a disruption in brain function. Seeing any of these signs, especially together, signals a potential stroke and demands urgent evaluation. Rapid EMS activation is critical because stroke treatment is time-sensitive. Neurons die as time passes, so getting the patient to care quickly minimizes brain damage and improves outcomes. Early EMS involvement allows prehospital teams to notify the stroke center, expedite transport, and initiate imaging and treatment workflows as soon as the patient arrives. Ischemic strokes can be treated with intravenous thrombolytics within a limited window (about 4.5 hours from onset), and many patients with large-vessel occlusions may benefit from mechanical thrombectomy within a broader but still limited window. This is why calling EMS immediately for possible stroke is the best choice.
