Final answer:
The key signs of alcohol overdose include depressed or irregular breathing, mental confusion or stupor, and vomiting. Increased coordination and balance are not signs of alcohol overdose.
Step-by-step explanation:
One key sign of alcohol overdose (alcohol poisoning) is severely depressed or irregular breathing. When alcohol is consumed in excessive amounts, it can depress the central nervous system, leading to slowed or shallow breathing. Another key sign is mental confusion or stupor. Alcohol overdose can impair cognitive functions and lead to confusion, disorientation, and loss of consciousness. Vomiting is also a key sign of alcohol overdose. The body may attempt to expel the toxins by inducing vomiting.
However, a key sign that is NOT associated with alcohol overdose is increased coordination and balance.
