21 multiple choice 2 points
drinking five or more alcoholic drinks at a sitting is called:

• binge drinking.
• alcohol abuse.
• alcohol poisoning.
• moderate drinking.

Explanation:

Question 19

Steroids are related to hormone regulation and muscle growth, not CNS depression. Carcinogens cause cancer, not the listed effects. Stimulants excite the CNS, opposite of depression. Inhalants can depress the CNS and cause slurred speech, glassy stare, impaired judgment.

Marijuana impairs short - term memory and reaction time, increases lung cancer risk (due to smoke), and can decrease testosterone in males. So all the listed risks are associated with marijuana use.

Binge drinking is defined as consuming five or more alcoholic drinks (for men) or four or more (for women) in one sitting. Alcohol abuse is a broader pattern of harmful use. Alcohol poisoning is a severe overdose. Moderate drinking is lower - level, regular consumption.

Answer:

D. Inhalants
