What indicates that further teaching is needed regarding reducing allergens in an adolescent's bedroom?

Using flat outdoor carpeting to cover hardwood floors indicates that further teaching may be needed regarding reducing allergens in an adolescent's bedroom because this choice does not effectively minimize allergens. Outdoor carpeting can be a source of allergens itself, as it may trap dust, pet dander, and other allergens within its fibers, which is counterproductive for someone looking to reduce allergen exposure.

In contrast, the other options directly contribute to a cleaner and healthier environment. Removing stuffed animals helps decrease dust accumulation, while washing bedding in hot water weekly eliminates dust mites and allergens effectively. Using an air purifier can help to reduce airborne allergens, making the room safer for someone who may be sensitive to allergens. Together, these choices reflect practices aimed at lowering allergen levels in the bedroom, while the use of outdoor carpeting may require further education to understand its potential drawbacks in allergen management.
