What are the signs of alcohol poisoning?

The signs of alcohol poisoning include unconsciousness, vomiting, irregular breathing, and low body temperature, making this the correct choice. Understanding these symptoms is crucial because they indicate a potentially life-threatening situation requiring immediate medical attention.

Unconsciousness is a critical sign, as a person who cannot be awakened may be at serious risk of choking on their vomit or experiencing respiratory failure. Vomiting is another alarming symptom, especially if it occurs while the person is unconscious, as it increases the risk of aspiration. Irregular breathing suggests a depressed central nervous system, which can be a direct result of alcohol's effects on the body. Low body temperature, or hypothermia, can occur in cases of severe alcohol poisoning due to the body's inability to regulate temperature effectively when intoxicated.

The other options describe symptoms that may occur with alcohol consumption but do not match the severity or urgency associated with alcohol poisoning. While fatigue and dizziness can be signs of excessive alcohol consumption, they are not as critical as those listed in the correct answer. Excessive sweating and a rapid heartbeat may indicate anxiety or high levels of alcohol consumption but are not specific indicators of poisoning. Hangover symptoms generally arise after the effects of alcohol have worn off and indicate a less severe condition than alcohol poisoning.
