Which of the following is a symptom of carbon monoxide poisoning?

Nausea is a well-recognized symptom of carbon monoxide poisoning. When carbon monoxide enters the bloodstream, it interferes with the body's ability to transport oxygen, which can lead to various physical responses. Nausea can occur as the body reacts to the diminished oxygen levels and the presence of carbon monoxide. It is important for boaters and individuals exposed to potential sources of carbon monoxide to be aware of this symptom, as it can be an early indicator of carbon monoxide poisoning, prompting immediate action to remove themselves from the source of exposure. Understanding the symptoms associated with carbon monoxide poisoning is crucial, especially in maritime environments where the gas can accumulate from engine exhaust.
