Caffeine questions often ask you to compare amounts, sources, coffee differences, and current guidance rather than recall one fact. You will also work through direct knowledge, application, comparison, role judgment, and two-step thinking. The questions focus on caffeine effects, pregnancy and breastfeeding, coffee preparation, less obvious caffeine sources, decaffeinated coffee, support-worker awareness, and current Nova Scotia guidance.
What This Quiz Covers
- Caffeine amounts and effects in adults
- Pregnancy, pregnancy planning, and breastfeeding
- Coffee serving size, preparation differences, and decaffeinated coffee
- Caffeine sources and caffeine-containing herbs
- Support-worker caffeine awareness, current Nova Scotia child guidance, and supplemented-food labelling

#1. Which approach best matches a support worker’s caffeine awareness responsibility?
Correct answer: A. Consider both personal and client intake from the full range of sources
Explanation: A support worker should remain aware of both personal and client caffeine intake. Total intake matters because excess caffeine is associated with significant adverse effects.
Why B is wrong: It considers the client but leaves out other caffeine sources.
Why C is wrong: It includes personal intake but omits awareness of client intake.
Why D is wrong: It includes both people but ignores caffeine from smaller servings and other sources.
#2. Which daily caffeine amount is associated with no adverse effects in adults?
Correct answer: B. 400 mg/day
Explanation: The adult amount identified with no associated adverse effects is 400 mg/day. The other amounts relate to different groups or coffee examples.
Why A is wrong: 300 mg/day applies to pregnancy, planning pregnancy, and breastfeeding.
Why C is wrong: 595 mg is the caffeine amount in the 600-mL coffee example.
Why D is wrong: 106 mg is an amount associated with a 240-mL instant coffee.
#3. Two adults each report three cups of coffee a day. Which information gives the best comparison of their caffeine intake?
Correct answer: B. Volume and caffeine content of each cup
Explanation: Cup count alone does not show total caffeine intake. Cup volume and caffeine content give the information needed for the strongest comparison.
Why A is wrong: Time of day does not establish how much caffeine was consumed.
Why C is wrong: Volume helps, but equal volumes still contain different caffeine amounts.
Why D is wrong: Preparation matters, but it does not replace knowing serving volume and caffeine content.
#4. Which fixed age-band amounts were replaced by current weight-based guidance for children and adolescents?
Correct answer: A. Ages 4–6, 45 mg, ages 7–9, 62.5 mg, ages 10–12, 85 mg
Explanation: Those are the older fixed age-band figures. Current guidance for children and adolescents up to 18 years uses body weight instead.
Why B is wrong: It assigns each fixed amount to the wrong age band.
Why C is wrong: It reverses the age-band pattern.
Why D is wrong: It switches the amounts for the two older age groups.
#5. An adult drinks one 600-mL coffee containing 595 mg of caffeine. Which interpretation is best?
Correct answer: B. The serving exceeds 400 mg, so serving size and caffeine content matter
Explanation: A single 600-mL coffee in this example contains 595 mg, which exceeds the 400 mg/day adult amount. Counting it as merely one cup hides important information about the serving.
Why A is wrong: One serving still contains a high caffeine amount when the serving is large.
Why C is wrong: Preparation method also affects caffeine content.
Why D is wrong: Serving size remains important when estimating intake.
#6. Which statement does NOT match current Canadian supplemented-food labelling rules?
Correct answer: C. Added caffeine amounts do not need to be identified on supplemented foods
Explanation: That statement reflects older labelling information rather than the current supplemented-food rules. Current labelling provides total supplemental-ingredient amounts, and the caffeine total includes its identified sources.
Why A is wrong: This matches the current labelling requirement.
Why B is wrong: Naturally present caffeine contributes to the caffeine total.
Why D is wrong: Caffeine from flavourings and food additives contributes to the caffeine total.
#7. In Nova Scotia, which daily caffeine guidance applies to children and adolescents up to 18 years?
Correct answer: C. 2.5 mg/kg of body weight per day
Explanation: Current guidance uses body weight for children and adolescents up to 18 years. The older fixed age-band amounts do not represent the current guidance.
Why A is wrong: 45 mg/day is an older fixed age-band figure.
Why B is wrong: 62.5 mg/day is an older fixed age-band figure.
Why D is wrong: 85 mg/day is an older fixed age-band figure.
#8. Which 240-mL decaffeinated-coffee comparison is correct?
Correct answer: B. Filter-dripped, 3 mg, instant, 5 mg
Explanation: Decaffeinated coffee still contains caffeine. The filter-dripped example contains 3 mg, while the instant decaffeinated example contains 5 mg.
Why A is wrong: It reverses the two amounts.
Why C is wrong: The instant example contains more than 3 mg.
Why D is wrong: The filter-dripped example contains less than 5 mg.
#9. Which people share a recommendation of no more than 300 mg of caffeine per day?
Correct answer: C. People who are pregnant, planning pregnancy, or breastfeeding
Explanation: The 300 mg/day recommendation applies to all three groups. Leaving out any one of them makes the statement incomplete.
Why A is wrong: It leaves out people planning pregnancy.
Why B is wrong: It leaves out people who are breastfeeding.
Why D is wrong: Adults in general have a different amount identified for them.
#10. One person drinks two 240-mL coffees containing 135 mg each. Another drinks one 600-mL coffee containing 595 mg. Who consumes more caffeine?
Correct answer: D. The 600-mL drinker by 325 mg
Explanation: Two 135 mg coffees total 270 mg. The 600-mL coffee contains 595 mg, which is 325 mg more.
Why A is wrong: The two smaller coffees contain less caffeine overall.
Why B is wrong: 270 mg and 595 mg are not equal.
Why C is wrong: 460 mg is not the difference between the two totals.
How to Read Your Score
Your score shows how well you understood the material in this attempt. Use 80% or higher as a personal study target for this website quiz, not an official passing score. A score from 60% to 79% points to areas that need more review. Below 60% means it is worth returning to the matching study notes before another attempt. Each attempt uses a random selection from the larger question bank, so another attempt might contain different questions. These score ranges only guide your study decisions.
What Your Mistakes Might Show
Look at the kinds of questions that caused trouble. Missed comparison questions might point to confusion when separating caffeine amounts, coffee preparations, or regular and decaffeinated coffee information. Missed application or two-step questions might show that caffeine effects, current child and adolescent guidance, supplemented-food labels, or caffeine sources need another review. Role-judgment mistakes might point to uncertainty about support-worker caffeine awareness in short situations. Use these patterns as useful review clues, not proof that you do not understand a whole area.
Questions You Guessed On Matter Too
Review more than the answers you got wrong. Notice questions you guessed on, changed several times, found difficult, or answered correctly without feeling sure. A correct guess raises your score, but it does not always show confident understanding. Check why the correct response fits and why the closest wrong answer choice does not fit.
Review and Retake
- Read the explanation for each question you missed.
- Identify why the wrong answer choice you selected seemed correct.
- Include questions you guessed on or felt unsure about.
- Review the matching section of the study notes.
- Explain the correct answer in your own words.
- Return later for another attempt after reviewing.
Focus on understanding why each response fits instead of memorizing answers from an earlier attempt. Leave some time between attempts when you need more review.
Track Your Quiz Progress
The quiz shows your score for the current attempt, but it does not keep a detailed study log. Record the date, score, one or two areas that caused trouble, and any questions you guessed on or felt unsure about. Use a notebook, planner, spreadsheet, or phone note. Another attempt might use a different question selection, so small score changes are normal. Look for clearer understanding and fewer uncertain answers over time instead of one perfect score.
A lower score gives you a useful place to focus. Pick the caffeine comparison, source, or guidance area that caused the most trouble, review it in the study notes, then return for another attempt when the ideas feel clearer.
