Sudden numbness and confusion are key signs of a stroke that a certified nursing assistant (CNA) should recognize. A stroke occurs when there is an interruption of blood flow to the brain, which can lead to neurological symptoms. Numbness, especially if it affects one side of the body, is indicative of potential damage to the areas of the brain responsible for motor function and sensation. Confusion or difficulty speaking are also critical signs since they reflect the stroke's impact on cognitive function and communication.

These symptoms are often summarized by the acronym FAST, which stands for Face drooping, Arm weakness, Speech difficulties, and Time to call emergency services. Recognizing these signs quickly is vital, as prompt medical action can significantly affect the outcome and recovery of a person experiencing a stroke.

The other options listed are not specific indicators of a stroke and do not reflect the typical symptoms associated with this medical emergency.
