What are common symptoms of carbon monoxide exposure?

Headaches, dizziness, disorientation, nausea, and fatigue are commonly recognized symptoms of carbon monoxide (CO) exposure. Carbon monoxide is a colorless, odorless gas produced by burning fossil fuels, and it can be hazardous when inhaled. The symptoms mentioned in this correct option reflect the body’s response to reduced oxygen levels due to CO binding with hemoglobin in the blood, which can lead to hypoxia—that is, a shortage of oxygen moving through the body. As carbon monoxide replaces oxygen in the blood, individuals may experience a range of symptoms that often mimic flu-like conditions, such as headaches and fatigue, making it crucial for people to recognize these signs as potential indications of dangerous CO exposure.

In contrast, the other options include symptoms that are not typically associated with CO exposure. For instance, blurred vision and rash might relate to other conditions, while coughing and chest pain are usually indicative of respiratory issues rather than carbon monoxide specifically. Moreover, symptoms like dry throat and euphoria are not indicative of CO poisoning and can arise from completely different health issues. Understanding these symptoms can be critical for ensuring safety and taking appropriate action in the event of exposure to carbon monoxide.
