Rationale: Difficulty speaking is a classic symptom of stroke, suggesting a potential blockage of blood flow to the brain. Prompt intervention is crucial to minimize brain damage. Elevated blood pressure (Choice A) may need management but is not the most urgent concern in this scenario. A blood glucose level of 180 mg/dL (Choice B) is slightly elevated but does not require immediate intervention for a suspected stroke. A temperature of 99.8°F (37.7°C) (Choice D) is within normal range and not a critical finding in this context.

The other options, such as showing statistical data (choice A), distributing informational brochures (choice C), and providing a list of treatment centers (choice D), may be informative but may not engage the audience on an emotional level as effectively as personal stories.
