An older person suddenly cannot move one side of the body and has slurred speech. What event is this most consistent with?

• A. Stroke
• B. Heart attack
• C. Seizure
• D. Migraine

Answer: (A)

This situation tests your ability to recognize a sudden focal neurologic deficit. Sudden onset of weakness on one side of the body with slurred speech in an older adult points most strongly to a stroke, caused by a disruption of blood flow to part of the brain. It’s a medical emergency because brain tissue can be damaged quickly without prompt treatment, so time is critical.

Think in terms of urgency: call emergency services right away and seek rapid evaluation. In stroke care, the goal is to restore blood flow as soon as possible, if appropriate.

Why the others don’t fit as well: a heart attack typically presents with chest discomfort, shortness of breath, and sometimes nausea or sweating rather than focal neurological symptoms like unilateral weakness and speech difficulty. a seizure can cause temporary symptoms and may lead to postictal weakness, but there’s usually a history of convulsions or altered consciousness around the event. migraines can cause aura and sensory changes, but sudden one-sided paralysis in an older adult is much more worrisome for stroke and requires immediate vascular assessment.
