What should you obtain when approaching a patient with a suspected stroke?

• A. Blood glucose
• B. Blood pressure
• C. Heart rate
• D. Respiratory rate

Answer: (A)

When approaching a patient with suspected stroke, the most important immediate step is to obtain a finger-stick blood glucose. Hypoglycemia can cause neurologic symptoms that mimic a stroke, such as confusion, weakness, speech difficulties, or facial droop, so quickly ruling it out is essential before proceeding with stroke-specific treatments or transportation decisions. A normal glucose level helps focus the assessment on neurological causes rather than a metabolic one. Vital signs like blood pressure, heart rate, and respiratory rate are still important for overall stability and to guide care, but they don’t identify a reversible mimicker as quickly as a glucose check. If glucose is low, treat promptly with appropriate glucose administration; if normal, continue the stroke assessment and pathway.
