Question

appropriate first - aid measures for dealing with carbon monoxide poisoning should not include getting brisk exercise. getting fresh air. seeking medical attention. leaving the suspected environment.

Explanation:

Carbon monoxide poisoning requires getting fresh air (to replace the carbon - monoxide - laden air), leaving the suspected environment (to stop further exposure), and seeking medical attention (for proper treatment like hyperbaric oxygen therapy). Brisk exercise increases the body's oxygen demand. But in carbon monoxide poisoning, the blood's ability to carry oxygen is impaired (due to carbon monoxide binding to hemoglobin). So, brisk exercise would worsen the situation as the body can't meet the increased oxygen demand.

Answer:

getting brisk exercise.
