1. 1What does viewing a house as a system imply when assessing occupant health?

   1. A.Each building component affects health independently of the others.
   2. B.Interactions among home components can affect occupant health.Correct answer: B
   3. C.The heating equipment determines health regardless of other conditions.
   4. D.Building condition matters only after occupants develop symptoms.

   Explanation: BPI describes knowledge of "how the different components of a home interact to affect occupant health." A system assessment considers these interactions rather than treating components as independent or relying on symptoms alone.

   Reference: BPI Healthy Housing Principles Certificate Scheme Handbook — Section 3, printed p. 2

2. 2Which feature of a pet is the direct source of animal allergens that can trigger asthma?

   1. A.Proteins in skin flakes and salivaCorrect answer: A
   2. B.Hair length regardless of protein exposure
   3. C.Coat color regardless of protein exposure
   4. D.Body size regardless of protein exposure

   Explanation: EPA states, "Proteins in your pet's skin flakes, urine, feces, saliva and hair can trigger asthma." The allergen is animal protein. Coat appearance and body size do not identify the allergenic substance.

3. 3Which statement accurately describes a possible health effect of exposure to damp, moldy indoor environments?

   1. A.Everyone exposed develops the same respiratory illness.
   2. B.Only people who can smell mold can develop symptoms.
   3. C.Some people may develop coughing or wheezing.Correct answer: C
   4. D.Symptoms cannot occur without direct skin contact.

   Explanation: CDC says, "For some people, mold can cause a stuffy nose, sore throat, coughing or wheezing, burning eyes, or skin rash." Effects vary; symptoms need not occur in everyone and are not limited to smelling mold or touching it.

4. 4Which statement correctly explains the asthma risk from cockroach residues in a home?

   1. A.Cockroach allergens cause exposure only through insect bites.
   2. B.Cockroach droppings or body parts can trigger asthma.Correct answer: B
   3. C.Cockroach residues are allergenic only while the insects are alive.
   4. D.Cockroach residues trigger asthma only when swallowed with food.

   Explanation: EPA states, "Droppings or body parts of cockroaches and other pests can trigger asthma." Allergens in these residues can cause respiratory reactions; exposure does not require a bite, swallowing contaminated food, or a living insect at the time of exposure.

5. 5Why do small airborne particles pose a health concern when breathed into the body?

   1. A.They are trapped completely outside the nose.
   2. B.They affect surfaces but cannot affect internal organs.
   3. C.They become harmless whenever they cannot be seen.
   4. D.They can reach deep into the lungs, and some enter the bloodstream.Correct answer: D

   Explanation: EPA explains that small particles "can get deep into your lungs, and some may even get into your bloodstream." Their size allows internal exposure; invisibility does not establish safety.

6. 6Which message accurately frames fall injuries in older adults for a healthy housing assessment?

   1. A.Falls are an unavoidable consequence of aging.
   2. B.Prevention is useful only after a major fracture.
   3. C.Proven measures can reduce and prevent falls.Correct answer: C
   4. D.Normal aging eliminates the value of home hazard reduction.

   Explanation: CDC states, "There are proven ways to reduce and prevent falls, even for older adults." Treating falls as inevitable or delaying prevention misses opportunities to reduce risk before an injury occurs.

7. 7What indoor-air problem can result when a home has too little exchange with outdoor air while indoor pollution sources continue operating?

   1. A.Pollutant concentrations remain fixed despite continued source emissions.
   2. B.Pollutants can accumulate to levels that affect health and comfort.Correct answer: B
   3. C.Pollutant concentrations fall because less outdoor air enters the home.
   4. D.Pollutant gases are unaffected because ventilation controls only particles.

   Explanation: EPA states, "If too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems." Continued emissions with insufficient outdoor-air exchange can increase concentrations. Reduced ventilation does not guarantee fixed or lower levels, and ventilation is not limited to particles.

8. 8Which condition describes hypothermia associated with excessive cold exposure?

   1. A.Abnormally low body temperatureCorrect answer: A
   2. B.Abnormally high body temperature
   3. C.Freezing damage confined to body tissues
   4. D.Muscle cramps associated with heat exposure

   Explanation: CDC defines hypothermia as "abnormally low body temperature". It concerns low body temperature, whereas high temperature, localized freezing injury, and heat cramps describe different thermal health conditions.

9. 9Why can poor maintenance of an ultrasonic or impeller humidifier affect indoor air quality?

   1. A.Its tank permanently traps every microorganism.
   2. B.It can disperse microorganisms from standing tank water into air.Correct answer: B
   3. C.It removes microorganisms only after visible dust appears.
   4. D.It sterilizes room air whenever the water level is high.

   Explanation: EPA states these humidifiers "can disperse materials, such as microorganisms and minerals, from their water tanks into indoor air." Standing water can support growth, linking maintenance to airborne exposure rather than guaranteed containment or sterilization.

10. 10A toddler puts a dust-covered toy into their mouth. Which exposure route describes swallowing contaminants from that dust?

    1. A.Inhalation
    2. B.Injection
    3. C.Absorption through skin
    4. D.IngestionCorrect answer: D

    Explanation: EPA explains that children put objects in their mouths, "increasing the chances of ingesting pollutants in dust or soil". Swallowing contaminated dust is ingestion. Inhalation involves breathing, skin absorption involves passage through skin, and injection involves penetration into tissue.
