All 14 questions in this test

Every question and its answer choices. The correct answers and explanations appear when you take the test above.

  1. Why is alcohol mixed with energy drinks a concern for servers?

    1. Energy drinks are banned in Alberta licensed premises
    2. Caffeine can mask intoxication, so a patron feels less drunk than they are
    3. Energy drinks lower the alcohol content of the mix
    4. Caffeine makes the body remove alcohol faster, so patrons sober up much sooner
  2. Which type of drink tends to enter the bloodstream fastest?

    1. A glass of still red wine
    2. A sparkling wine or a cocktail mixed with soda
    3. A flat beer served at room temperature
    4. A spirit mixed with orange juice
  3. What can happen when a patron combines alcohol and cannabis in the same session?

    1. Cannabis speeds up how fast alcohol leaves
    2. The effects of each cancel the other out
    3. Dehydration risk goes down with both
    4. Impairment can become greater and less predictable
  4. What effect does food have when a patron eats while drinking?

    1. It stops alcohol from reaching the blood as long as the meal is large
    2. It slows absorption but does not prevent intoxication
    3. It doubles the speed of absorption
    4. It has no effect on absorption at all
  5. For the after-1 a.m. limit, what is AGLC's standard serving of draught beer?

    1. 250 mL (9 oz)
    2. 568 mL (20 oz)
    3. 473 mL (16 oz)
    4. 341 mL (12 oz)
  6. How much 40% spirits makes one standard drink?

    1. 85 mL (3 oz)
    2. 43 mL (1.5 oz)
    3. 57 mL (2 oz)
    4. 28.5 mL (1 oz)
  7. A patron says two coffees will sober up his friend. What is true?

    1. Coffee halves the blood alcohol level
    2. A cold shower works faster than coffee
    3. Only time removes alcohol from the body
    4. Eating a large meal cancels the alcohol
  8. A patron orders a 341 mL bottle of 8.5% strong beer. Compared with a standard drink, it holds:

    1. Less pure alcohol than one standard drink
    2. About half a standard drink of alcohol
    3. More pure alcohol than one standard drink
    4. Exactly one standard drink of alcohol
  9. About how much pure alcohol is in one standard drink, according to AGLC's DrinkSense?

    1. 30 mL
    2. 5 mL
    3. 17 mL
    4. 43 mL
  10. How does age affect the way a person handles alcohol?

    1. Young adults process alcohol the slowest of all
    2. Age makes no difference to the effects
    3. Older people process it more slowly and may be more sensitive
    4. Older people build up tolerance over the years and feel alcohol less
  11. A patron believes switching between beer and spirits is what makes people drunk. What is correct?

    1. Only spirits cause intoxication, not beer
    2. The total alcohol consumed causes intoxication, not the mix
    3. Beer after spirits causes no intoxication
    4. Mixing different types of liquor doubles the effect of each drink
  12. Why may a woman feel the effects of the same drinks faster than a man?

    1. Women generally have less body fluid, so blood alcohol rises higher
    2. Women usually choose stronger drinks than men
    3. Alcohol affects everyone the same way by weight
    4. Women's livers break down alcohol faster, so it leaves their blood sooner
  13. What does AGLC say about drinking alcohol during pregnancy?

    1. Wine with meals is safe after three months
    2. No amount of alcohol is proven safe while pregnant
    3. One drink a day is considered safe
    4. Only spirits are a risk during pregnancy
  14. Which serving equals one standard drink?

    1. 473 mL (16 oz) of 5% beer
    2. 250 mL (9 oz) of 12% wine
    3. 60 mL (2 oz) of 40% spirits
    4. 142 mL (5 oz) of 12% wine

Alcohol and the body: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Lower-risk drinking (standard drinks)

  • A standard drink contains about 17 mL of pure alcohol.
  • One standard drink = 341 mL (12 oz) of 5% beer, 142 mL (5 oz) of 12% wine, or 43 mL (1.5 oz) of 40% spirits.
  • Beer can range from about 1.1% to 11% alcohol or more, so the same 341 mL bottle may hold less or more than one standard drink: about 9 mL of pure alcohol at 2.5%, 14 mL at 4%, 19 mL at 5.5%, 29 mL at 8.5% and 38 mL at 11%.
  • A cocktail does not contain less alcohol than a glass of wine just because it has mix: a standard drink holds the same alcohol whatever the type.
  • Large glasses make over-pouring easy: DrinkSense lists a Burgundy glass holding 654 mL (23 oz), a rocks glass 256 mL (9 oz) and a footed pilsner glass 511 mL (18 oz).

Myths and facts

  • Only time sobers a person up; fresh air, food, exercise, a cold shower or coffee do not.
  • Women generally have less body fluid, so the same amount of alcohol gives a higher blood alcohol concentration; they feel the effects faster and longer.
  • Food slows how fast alcohol is absorbed but does not prevent intoxication.
  • Bubbly drinks such as coolers, sparkling wine and cocktails with soda enter the bloodstream faster than flat drinks.
  • Switching between types of liquor does not in itself cause intoxication; the total alcohol does.
  • Older people process alcohol more slowly and may become more sensitive to it; in teens and young adults alcohol may affect physical and mental development.

Drinking within the guidelines

  • Tips: eat before and while drinking, stick to standard pours without top-ups, alternate with water (alcohol dehydrates), sip slowly, and have non-drinking days.
  • Caffeine in energy drinks can mask the effects of alcohol, so a person may feel less drunk than they are; hand-mixed energy drinks usually contain more caffeine than pre-mixed ones.
  • Mixing alcohol and cannabis can make impairment greater and less predictable, raise the risk of injury and poor judgment, and increase nausea, vomiting and dehydration.

5.3 standard liquor servings (for the after-1 a.m. limit)

  • Standard serving: spirits and liqueurs 28.5 mL (1 oz); wine 142 mL (5 oz); bottled or canned beer 341 mL bottle or 355 mL can; draught beer 341 mL (12 oz); cider or coolers 341 mL bottle or 355 mL can.
  • Note: this AGLC serving size for spirits (1 oz) is a policy measure for service limits and pricing; DrinkSense's health "standard drink" of spirits is 1.5 oz at 40%.

Common liquor questions; FASD poster

  • No amount of alcohol is proven safe during pregnancy; AGLC's Dry9 campaign encourages an alcohol-free pregnancy.
  • Class A licensees must post AGLC's Fetal Alcohol Spectrum Disorder (FASD) poster in a prominent place (Handbook 3.1).
