Which of the following is NOT part of the Cincinnati Prehospital Stroke Scale?

The Cincinnati Prehospital Stroke Scale (CPSS) is specifically designed to help first responders quickly assess potential strokes in patients. It includes three key components: asking the patient to show their teeth or smile to evaluate facial symmetry, having the patient close their eyes and hold out both arms to check for arm drift or weakness, and asking the patient to say a specific phrase to evaluate speech clarity and coherence.

Focusing on the correct answer, shining a light in the patient's eyes to assess reactivity is not a component of the Cincinnati Prehospital Stroke Scale. This action involves checking the reactions of the pupils and does not assess the specific symptoms related to strokes that the scale aims to identify. The CPSS is intended to be simple and focused on observable signs of a stroke, which makes this component irrelevant to its assessment.

While all other options directly relate to key elements of the CPSS, shining a light in the patient's eyes does not fit within the framework of this specific tool for stroke assessment.
