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

Carbon monoxide poisoning can manifest through various symptoms, and nausea is indeed one of the common symptoms. This occurs because carbon monoxide affects the body's ability to transport oxygen, leading to a range of physiological responses. When carbon monoxide is inhaled, it binds to hemoglobin in the blood more effectively than oxygen, causing a shortage of oxygen that can lead to nausea.

Other symptoms, such as headaches, confusion, and fatigue, are also associated with carbon monoxide poisoning; however, the presence of nausea is often reported by individuals experiencing this type of poisoning, making it a notable symptom. Understanding these symptoms is crucial for identifying and responding to potential carbon monoxide exposure, particularly in marine environments where engine emissions can lead to dangerous situations.
