Rhode Island Boater Practice Test

What action should be taken if someone on board a boat shows signs of carbon monoxide poisoning?

1. Move them to a ventilated area immediately

2. Give them water to drink

3. Keep them lying down on the boat

4. Monitor them until you reach shore

The correct answer is: Move them to a ventilated area immediately

Moving a person showing signs of carbon monoxide poisoning to a ventilated area is crucial because carbon monoxide (CO) is a colorless, odorless gas that can quickly lead to unconsciousness or even death in enclosed spaces. Fresh air helps dilute the concentration of CO around the affected individual, allowing them to breathe in cleaner air and start the recovery process. This action is essential because carbon monoxide binds to hemoglobin in the blood more effectively than oxygen does, reducing the amount of oxygen transported throughout the body. Quickly relocating the person to an area with good ventilation can help alleviate symptoms such as headache, dizziness, nausea, and confusion. While other options such as giving water or monitoring until reaching shore may seem helpful, they do not address the immediate danger of carbon monoxide exposure effectively. In severe cases, keeping someone lying down without adequate airflow can also worsen their condition. Therefore, ensuring that the person receives fresh air as soon as possible is the most critical step in managing carbon monoxide poisoning.
