Which of the following symptoms would require the activation of Protocol 28 for Stroke/TIA?

The activation of Protocol 28 for Stroke/TIA is specifically designed for conditions related to potential strokes or transient ischemic attacks (TIAs). Slurred speech and facial drooping are classic symptoms indicative of a stroke. These signs suggest that there may be an interruption of blood flow to the brain or that a part of the brain is not functioning properly, thus warranting immediate medical attention and intervention.

Recognizing these symptoms is crucial because they often reflect a loss of neurological function, and swift action can significantly affect the patient's outcome. Quick identification and response to strokes can lead to timely treatment, which is essential in minimizing potential brain damage and improving recovery chances.

In contrast, the other options presented do not fall within the specific symptomatic criteria for activating this protocol. Loss of consciousness and severe headache can indicate various conditions, not just stroke. Nausea and vomiting do not specifically indicate a stroke, as they could result from numerous medical issues. Severe chest pain often relates to cardiac issues rather than cerebrovascular events. Therefore, slurred speech and facial drooping are the definitive signs prompting the use of Protocol 28.
