What is evaluated in the Los Angeles Prehospital Stroke Screen?

1. Pulse and blood pressure

2. Asymmetry in facial smile and arm strength

3. Respiratory rate and depth

4. Temperature and mental status

The correct answer is: Asymmetry in facial smile and arm strength

The Los Angeles Prehospital Stroke Screen focuses on identifying signs of a stroke through specific physical assessments. The correct choice highlights the evaluation of asymmetry in facial smile and arm strength, which are critical indicators in diagnosing potential strokes. Facial asymmetry, as seen in the inability to smile evenly, and differences in arm strength are classic symptoms of a stroke, particularly in the context of an acute event. By assessing these signs, healthcare providers can quickly identify patients who may be experiencing a stroke and thus expedite necessary medical interventions. Rapid recognition of these symptoms is crucial given the time-sensitive nature of stroke treatment, where early intervention can significantly affect patient outcomes. The other options do not directly assess the hallmark symptoms associated with strokes and fail to address the primary goal of the screening tool, which is to identify stroke symptoms effectively.
