Quiz: Sleep, Fitness, and Emergency Response

Test your understanding of sleep, workout plan design, emergency response, and infectious disease prevention with these review questions.

  1. At least 60 minutes every day, made up of a mix of activity types
  2. Exactly 20 minutes, three times per week
  3. Only vigorous activity, at least 2 hours daily
  4. There is no specific daily guideline for adolescents
Show Answer

The correct answer is A. National guidelines recommend adolescents get at least 60 minutes of physical activity every day, made up of a mix of moderate, vigorous, muscle-strengthening, and bone-strengthening activity across the week.

2. According to the chapter, what is the correct first step when a scene may be unsafe, such as a downed power line near an injured person?

  1. Approach immediately to help, since helping quickly is always the top priority
  2. Call emergency services from a safe distance and wait for trained responders rather than entering the danger yourself
  3. Wait for the injured person to call for help themselves
  4. Only worry about scene safety after providing first aid
Show Answer

The correct answer is B. The chapter is explicit that if a scene is not safe, the correct action is to call emergency services from a safe distance and wait for trained responders. A helper who gets hurt approaching an unsafe scene becomes a second person needing rescue.

3. Why does the chapter say there is no single "correct" bedtime routine for every family?

  1. Because sleep duration doesn't actually matter for health
  2. Because only Western sleep schedules are backed by science
  3. Because sleep duration targets can be met through many different cultural arrangements, such as shared sleeping spaces or schedules built around seasonal daylight
  4. Because cultural sleep practices are outdated compared to a fixed clock schedule
Show Answer

The correct answer is C. The chapter describes many valid cultural sleep arrangements, such as shared family sleeping spaces or schedules built around seasonal daylight, and notes that science-based sleep duration targets can be met through many different structures.

4. How does the chapter distinguish moderate activity from vigorous activity using the "talk test"?

  1. Moderate activity always lasts longer in total minutes than vigorous activity
  2. Vigorous activity refers only to activities done indoors
  3. The talk test measures how loudly a person can speak, not their breathing
  4. During moderate activity a person can talk in full sentences; during vigorous activity only a few words can be said at a time
Show Answer

The correct answer is D. The talk test distinguishes the two intensities: moderate activity allows full sentences, while vigorous activity raises heart rate and breathing enough that only a few words can be said at a time.

5. Why does the chapter emphasize that each infectious disease transmission route needs its own specific prevention strategy?

  1. Prevention only works if it targets the actual way a disease spreads, such as handwashing for direct contact versus safe food handling for foodborne illness
  2. All transmission routes are prevented by the exact same single method
  3. Prevention strategies work regardless of which transmission route is involved
  4. Only airborne transmission can actually be prevented
Show Answer

The correct answer is A. The chapter explains that understanding how a disease spreads is key to knowing which prevention strategy works, which is why hygiene, food and water safety, and PPE each target a specific transmission route rather than one universal method.

6. A person is coughing forcefully and can still speak in short bursts. Based on the chapter's choking-response guidance, what should a bystander do?

  1. Immediately begin abdominal thrusts, since any coughing means the airway is blocked
  2. Encourage them to keep coughing rather than performing abdominal thrusts, since they can still cough and speak
  3. Wait several minutes to see if the coughing stops before doing anything
  4. Assume the situation is not urgent and walk away
Show Answer

The correct answer is B. The chapter's Heimlich maneuver steps specify that abdominal thrusts should not be performed on someone who can still cough forcefully or speak; instead, encourage them to keep coughing, since that means their airway is not fully blocked.

7. A student wants to build a complete week of physical activity. Which combination best reflects the chapter's guidance for a balanced plan?

  1. Only vigorous running, every single day of the week
  2. Only muscle-strengthening activity, since it covers every fitness need
  3. A mix of moderate activity most days, vigorous activity at least 3 days, and muscle- and bone-strengthening activity at least 3 days a week
  4. Any single activity type repeated daily, since variety doesn't matter
Show Answer

The correct answer is C. A well-designed plan intentionally balances different activity types across the week rather than relying on one favorite type, since each type builds a different part of fitness.

8. At a picnic, cooked chicken has been sitting out at room temperature for over two hours. Applying the chapter's food safety guidance, what should happen next?

  1. The chicken is still safe indefinitely since it was fully cooked earlier
  2. Only raw meat needs temperature monitoring, not cooked meat
  3. Reheating the chicken briefly makes any time spent at room temperature irrelevant
  4. Treat the chicken as unsafe, since the danger zone between about 40°F and 140°F allows bacteria to multiply quickly over that much time
Show Answer

The correct answer is D. The chapter explains that food should not sit at room temperature for long periods because the "danger zone" between about 40°F and 140°F allows bacteria to multiply quickly, regardless of whether the food was cooked properly earlier.

9. Comparing two emergencies at the same time — one person is not breathing, and another has a painful but stable broken arm — how does the chapter say a responder should prioritize?

  1. The person who is not breathing takes priority, since life-threatening conditions are addressed before less urgent injuries, even ones that look more painful
  2. The broken arm should be treated first since it is more visibly painful
  3. Both should be treated in the exact order they were noticed, regardless of severity
  4. Priority should go to whichever person asks for help first
Show Answer

The correct answer is A. The chapter's priority order addresses the most life-threatening conditions first. Someone not breathing takes priority over someone with a broken arm, even though the broken arm may look more painful in the moment.

10. A student compares wearing gloves while helping a classmate with a bleeding scrape to wearing gloves while eating lunch with friends. What does analyzing these two situations show, based on the chapter's PPE guidance?

  1. Gloves should be worn in both situations at all times, regardless of context
  2. Gloves address a real transmission risk in the bleeding-scrape situation, but are unnecessary for eating lunch, since PPE should match the specific transmission risk present
  3. PPE is never necessary at school, in any situation
  4. Wearing gloves during lunch improves hygiene more than washing hands does
Show Answer

The correct answer is B. The chapter describes PPE as addressing specific higher-risk situations, such as first aid involving bodily fluids, not everyday activities like eating lunch. Knowing when a situation actually calls for PPE is itself a practical health skill.
