Question 1

A patient with dust mite allergy asks about the best mattress encasement. Which feature is MOST important?

Accepted Answer

Pore size of 10 microns or less

Answer

Encasements must have pore sizes of 10 microns or less to block dust mite allergen particles effectively.

Question 2

Which indoor relative humidity level BEST inhibits dust mite growth?

Accepted Answer

Below 50%

Answer

Maintaining indoor relative humidity below 50% significantly inhibits dust mite survival and reproduction.

Question 3

A family reports cockroach infestation in their apartment. Which asthma educator recommendation is MOST evidence-based?

Accepted Answer

Seal cracks, fix leaks, and use boric acid baits

Answer

Integrated pest management—sealing entry points, eliminating moisture, and using targeted baits—is the most evidence-based approach to cockroach control.

Question 4

Which statement about air purifiers with HEPA filters is MOST accurate for asthma management?

Accepted Answer

They are effective for airborne particulates but not volatile organic compounds

Answer

HEPA filters capture particulate allergens effectively but do not remove gaseous pollutants or VOCs, which require activated carbon filters.

Question 5

A patient's child has a pet cat, and the family is unwilling to remove it. What is the NEXT best recommendation?

Accepted Answer

Keep the cat outdoors, wash hands after contact, and use HEPA filters

Answer

When pet removal is not acceptable, keeping pets outdoors, handwashing, and using HEPA air filtration can reduce but not eliminate allergen exposure.
