What factors can influence the absorption of alcohol in breath tests?

Body weight, metabolic rate, and food consumption are all significant factors that influence the absorption of alcohol in breath tests.

Body weight is crucial because it determines how alcohol distributes throughout the body. Individuals with a higher body weight generally have a larger volume of body water, which can dilute the concentration of alcohol in their system compared to those with lower body weight.

Metabolic rate also plays an essential role in how quickly alcohol is processed by the body. People with a higher metabolic rate may break down alcohol more quickly than those with a slower metabolism, affecting the amount of alcohol present in the bloodstream at any given time.

Food consumption impacts the absorption rate of alcohol. When food is present in the stomach, it can slow down the absorption of alcohol into the bloodstream, often resulting in a lower breath alcohol concentration when a breath test is conducted shortly after drinking.

The other options contain factors that are less directly related to the physiological processes affecting alcohol absorption. While height, drinking speed, and hydration can have some influence, they do not have as clear and direct an impact as the factors included in the selected choice.
