What are some signs of a stroke?

Signs of a stroke typically include confusion, slurred speech, and localized weakness, making this the correct choice. Confusion can manifest as difficulty in understanding or responding, while slurred speech indicates that the person is having trouble articulating words, which are both significant neurological signs. Localized weakness may present as a noticeable reduction in strength in one side of the body or difficulty raising an arm, indicating potential brain activity disruption.

Other symptoms of a stroke can include facial droop, difficulty walking, and severe headache, but the presence of confusion, slurred speech, and localized weakness effectively highlight acute neurological changes that require immediate medical attention. These symptoms are associated with how a stroke affects the blood supply to different parts of the brain, critically impairing brain function.

In contrast, options that include only headache and fatigue do not adequately encompass the specific neurological indicators of a stroke. High fever and vomiting, or rapid heart rate and low blood pressure, are more indicative of other medical conditions, thus do not align with the specific signs one would assess for stroke recognition.
