In the stroke assessment, what does the 'A' component indicate?

• A. Armpit sweating
• B. Absence of chest movement
• C. Ankle swelling
• D. Arm weakness on one side

Answer: (D)

The main thing being tested is whether one arm shows weakness or drifts compared with the other. In many rapid stroke assessments, you check for arm weakness on one side because a stroke often disrupts the brain areas that control muscle strength on that side of the body. To test it, you ask the person to extend both arms straight ahead with palms up and hold still for a few seconds. If one arm drifts downward or can’t stay in place, it suggests a problem with motor function on that side and raises concern for stroke, requiring urgent medical attention.

The other signs listed don’t fit stroke screening. Sweating under the armpit isn’t a stroke-specific cue, absence of chest movement points to breathing issues rather than a brain attack, and ankle swelling isn’t an acute stroke indicator.
