What are key signs of stroke according to the FAST acronym?

The FAST acronym is a widely recognized tool used to identify the key signs of a stroke, and it stands for Face drooping, Arm weakness, Speech difficulties, and Time to call emergency services.

Face drooping refers to the uneven or drooping appearance of one side of the face, which can manifest when a person smiles or attempts to speak. Arm weakness is assessed by having the person raise both arms; if one arm drifts downward, it may indicate weakness on one side of the body, which is a common symptom of a stroke. Speech difficulties may include slurred speech or struggles to speak clearly, which can occur during a stroke. The "Time" component emphasizes the importance of calling emergency services immediately if any of the previous signs are observed; timely medical intervention is critical in reducing the potential damage caused by a stroke.

The other options do not accurately represent the key signs of a stroke as outlined in the FAST acronym. Symptoms such as fever, abdominal pain, fainting, or fatigue do not directly correlate with stroke recognition and do not provide the urgency needed in a stroke situation. Therefore, the given answer highlights the correct components necessary for identifying a stroke and the critical steps to take in response.
