Which of the following is a sign of stroke?

• A. Slurred speech
• B. Slow, deep breathing
• C. Slow, strong pulse
• D. Nausea and vomiting

Answer: (D)

Speech disturbance is a key indicator that brain function is affected during a stroke; when blood flow to language areas of the brain is disrupted, speech can become slurred, words may be hard to form, or comprehension may be impaired. This makes slurred speech the most direct sign among the options for recognizing a stroke in an emergency. In contrast, slow, deep breathing can arise from other medical issues affecting respiration; a slow, strong pulse is not a typical stroke signal, and nausea or vomiting can occur for many reasons and is not a reliable sign of stroke on its own. If stroke is suspected, act quickly: call emergency services, determine when symptoms began, monitor breathing, keep the person safe and comfortable, and avoid giving anything by mouth until professionals arrive.
