For the first Question: The right answer is only A.
After people have drunk, it will be harder for them to make quick decisions, as is the case in driving, since motor coordination and judgment are impaired,
It can take up to two hours or more to get rid of the alcohol (it depends on the ethnicity of the person and whether it is a regular drinker or not), so it would take a lot more than an hour to get rid of alcohol in the body.
For the second question: the right answer is All above
According to the National Institute on Alcohol Abuse and Alcoholism in the USA, one standard drink contains approximately 14 grams of pure alcohol, which represents the measures mentioned in the MCQ.
For the third question:
When the victim has just absorbed too much toxic, he initially has troubles of consciousness and a ventilatory stop that can change, in the absence of first aid, to death.
As soon as you discover this toxic abuse, call the SAMU (15) and do the first aid:
In case of disturbances of consciousness, carefully tilt your head backward.
Check for the presence of breathing movements, and place the casualty in the lateral safety position.
In the presence of respiratory arrest, after having checked the presence of a carotid pulse, practice mouth-to-mouth.
In all cases, surveillance of the victim is mandatory until the arrival of medical aid.
