What is the purpose of the FAST exam in the field?

• A. Rapid assessment for signs of stroke: Face, Arms, Speech, Time
• B. Assessment of airway patency
• C. Evaluation of blood glucose
• D. Rapid assessment for signs of stroke focusing on facial droop, arm drift, speech, and time

Answer: (A)

The question tests recognizing stroke quickly in the field using a simple, widely taught mnemonic. The FAST exam stands for Face, Arms, Speech, Time, guiding you to rapidly check for facial droop, arm drift, and slurred or abnormal speech, then act quickly because time matters for treatment decisions. This concise check helps EMS determine if a patient might be having a stroke and prioritize transport to a facility capable of urgent stroke care.

Why this is the best match: it directly names the four components of the mnemonic and emphasizes the urgency implied by “Time,” which drives rapid decision-making and transfer to appropriate care. The other options describe unrelated assessments (airway patency, glucose) or restate the signs without the established mnemonic, so they don’t align with the standard, time-sensitive stroke recognition tool.
