Question 1

Which cleaning method is RECOMMENDED for reducing dust mite allergen on hard floors in a home with asthma patients?

Accepted Answer

Damp mopping or damp dusting

Answer

Damp mopping and damp dusting capture allergen particles rather than dispersing them into the air, as dry methods can do.

Question 2

A patient asks whether gas stoves contribute to asthma symptoms. What is the CORRECT response?

Accepted Answer

Gas stoves produce nitrogen dioxide, a known asthma trigger, especially in poorly ventilated kitchens

Answer

Gas stoves emit nitrogen dioxide and other combustion byproducts that can reach irritating concentrations indoors and worsen asthma, particularly without ventilation.

Question 3

Which strategy MOST effectively reduces exposure to secondhand smoke for a child with asthma whose parent smokes?

Accepted Answer

Parent smokes outside the home and changes clothes before re-entering

Answer

Smoking outside and changing clothes minimizes thirdhand smoke residue brought indoors; smoking anywhere near the home still exposes the child to harmful particles.

Question 4

Which indoor plant characteristic is relevant to asthma management?

Accepted Answer

Overwatered plants can promote mold growth in soil, worsening asthma

Answer

Overwatered houseplant soil is a common site of mold growth, which can release spores and worsen asthma symptoms.

Question 5

A school reports a student's asthma worsens every Monday. What environmental cause should be investigated FIRST?

Accepted Answer

Volatile organic compounds from weekend cleaning products not yet aired out

Answer

Weekend cleaning with VOC-containing products in a closed building can leave elevated chemical concentrations that peak when students return Monday.
