Which of the following is a sign of a stroke?

Numbness in the limb
High fever
Increased heart rate
Excessive sweating

The correct answer is: Numbness in the limb

Numbness in the limb is a classic symptom of a stroke, often associated with the sudden onset of neurological deficits. When a stroke occurs, it can disrupt blood flow to parts of the brain, leading to a loss of function in the areas of the body controlled by the affected brain regions. This can result in weakness, paralysis, or numbness on one side of the body, frequently affecting one arm or leg. Recognizing this sign is critical for timely medical intervention, which is crucial for improving outcomes in stroke patients. The other options do not specifically indicate a stroke. High fever can be associated with infections or other medical conditions but is not a direct sign of a stroke. Increased heart rate may occur for various reasons, including anxiety or dehydration, but it is not a specific indicator of a stroke. Excessive sweating can also arise from numerous causes like anxiety, heat, or infections and does not specifically relate to the neurological symptoms associated with a stroke.
