To reduce allergic triggers in an asthmatic child's home, which recommendation should the nurse provide?

Maintaining humidity levels between 50% and 60% is crucial for reducing allergic triggers in an asthmatic child's home. Optimal humidity helps prevent the growth of mold and dust mites, both of which are common indoor allergens that can exacerbate asthma symptoms. Humidity levels above this threshold can lead to increased moisture in the air, creating an environment conducive to the proliferation of these allergens. Conversely, excessively low humidity can lead to other respiratory issues and discomfort.

In addition, sustaining humidity within the recommended range enhances overall air quality, which is essential for individuals with asthma. It helps ensure that the respiratory system remains as comfortable as possible, minimizing the likelihood of triggering an asthma attack.

The other recommendations, such as increasing humidity to 70%, using scented room deodorizers, or vacuuming the carpet only once a month, do not provide the necessary support for managing asthma. High humidity can lead to mold growth, scented products can introduce additional irritants, and infrequent vacuuming does not adequately remove dust mites and other allergens.
