NAECB Environmental Control 4

Question 1

Which of the following is an example of PRIMARY prevention of asthma triggers in the home?

Accepted Answer

Choosing hard-surface flooring instead of carpet when remodeling

Answer

Selecting hard floors instead of carpet during remodeling eliminates the primary reservoir for dust mite allergen before it is established.

Question 2

A patient asks about using scented candles at home. How should the asthma educator respond?

Accepted Answer

Burning candles produce particulate matter and VOCs that can trigger asthma

Answer

All burning candles release fine particulate matter, soot, and volatile organic compounds that can irritate airways and trigger asthma regardless of the wax type.

Question 3

An asthmatic child's symptoms consistently worsen at their grandparent's home but not at their own home. What is the MOST likely environmental explanation?

Accepted Answer

The grandparent's home likely has different allergen or irritant exposures such as pets, smoke, or older carpeting

Answer

Location-specific symptom patterns strongly suggest exposure to a different set of environmental triggers at that location, such as pets, tobacco smoke, or accumulated allergens.

Question 4

Which approach is MOST effective for reducing indoor ozone levels that can worsen asthma?

Accepted Answer

Increasing ventilation and avoiding ozone-generating devices

Answer

Ozone-generating air purifiers actually worsen indoor ozone levels; the best strategies are avoiding such devices and increasing fresh air ventilation.

Question 5

What is the recommended wash temperature for bedding to effectively kill dust mites?

Accepted Answer

Hot water at least 130°F (54°C)

Answer

Washing bedding in water at 130°F (54°C) or higher kills dust mites; lower temperatures may clean but do not reliably kill mites.
