Multiple Choice

Alcohol poisoning is most closely associated with which of the following?

A blood alcohol content above .08.

Depression of signals in the respiratory center of the brain.

Acute liver failure.

Toxic buildup of acetaldehyde in the blood.

Previous problemNext problem

Verified step by step guidance

Understand that alcohol poisoning primarily affects the central nervous system, particularly the brain's control centers.

Recognize that blood alcohol content (BAC) above 0.08 is legally considered intoxicated but does not directly define alcohol poisoning.

Identify that acute liver failure and toxic buildup of acetaldehyde are related to chronic alcohol abuse or metabolic effects, not the immediate cause of alcohol poisoning.

Focus on the respiratory center in the brainstem, which controls breathing; alcohol poisoning can depress these signals, leading to respiratory failure.

Conclude that the most critical and immediate danger in alcohol poisoning is the depression of signals in the respiratory center of the brain, which can be life-threatening.
