Final answer:
In cases of suspected carbon monoxide poisoning, it is imperative to seek medical attention immediately, ensure the person is breathing fresh air, and administer oxygen to counteract the effects of CO on hemoglobin.
Step-by-step explanation:
If someone is suspected of suffering from carbon monoxide poisoning, the correct action is to seek medical attention immediately (Choice C). Carbon monoxide is a colorless, odorless gas that can cause symptoms similar to the flu, such as headaches, dizziness, and confusion, and at high levels it can result in unconsciousness or death. The initial treatment for someone suffering from carbon monoxide poisoning is to immediately remove the person from the exposure to fresh air and ensure that they are breathing normally; this may involve performing CPR if they are unconscious.
Administering oxygen is crucial because it helps to displace the carbon monoxide from hemoglobin, restoring the body's ability to transport oxygen to where it is needed. In cases of severe poisoning, treatment with 100% oxygen or in a hyperbaric oxygen chamber may be necessary. It is essential to act fast and get professional help, as carbon monoxide binds very strongly to hemoglobin, which impedes the delivery of oxygen throughout the body. Options A, B, and D are incorrect and could potentially worsen the situation.
