ENT · Nose and paranasal sinuses: house dust mite avoidance

Sample item

A child with perennial allergic rhinitis has a strongly positive skin prick test to Dermatophagoides. Which environmental measure is most useful?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Mattress and pillow covers with hot washing of bedding

Mites live in bedding and soft furnishings. Impermeable covers and washing bedding hot reduce exposure. Carpets and soft toys harbour mites, and open windows bring in pollens.

Option by option

  • A. Using carpets to filter dust

    Carpets trap and harbour mites, increasing exposure.

  • B. Keeping windows open at night

    Open windows at night increase pollen and dust exposure.

  • C. Daily use of room fresheners

    Room fresheners add irritants and do not remove mites.

  • D. Mattress and pillow covers with hot washing of bedding (correct)

    Correct. Encasing bedding and washing it hot cut mite exposure.
