What is the earliest clinical manifestation of biliary atresia?

The correct answer is choice A, E.

Choice A rationale:

Using an air conditioner is an effective way to reduce exposure to pollens and dust. Air conditioners filter the air and help prevent outdoor allergens from entering the indoor environment. This choice is correct because it addresses one of the primary sources of exposure to allergens.

Choice B rationale:

Keeping humidity in the house above 60% is not a recommended approach. High humidity can promote the growth of mold and dust mites, which can exacerbate allergies. Maintaining humidity levels between 30-50% is generally recommended for reducing allergen exposure.

Choice C rationale:

Keeping pets outside might seem like a logical option to reduce allergen exposure; however, pet allergens can still be carried indoors on clothing and shoes. Moreover, if individuals are not allergic to pet dander, keeping the pets inside may not pose an issue.

Choice D rationale:

Replacing wall-to-wall carpeting with wood and tile floors is a good strategy for reducing allergen exposure. Carpets can trap dust, pollen, and other allergens, while hard surfaces are easier to clean and do not accumulate allergens as readily. This choice is correct because it addresses a common source of indoor allergens.

Choice E rationale:

Putting dust-proof covers on pillows and mattresses is another effective strategy for reducing allergen exposure. These covers create a barrier that prevents dust mites and their allergens from permeating the sleeping environment. This choice is correct because it directly addresses the issue of dust mite allergens.

The correct answer is choice C. Dyspnea.

Choice A rationale:

Orthopnea. Orthopnea refers to difficulty in breathing that occurs when lying flat. It is not the term used to describe labored breathing, which is the main concern in this question.

Choice B rationale:

Hypopnea. Hypopnea is a term used to describe shallow or slow breathing, usually during sleep. It is not the term used to describe the labored breathing mentioned in the question.

Choice C rationale:

Dyspnea. This is the correct term to describe labored breathing, which is characterized by a subjective sensation of discomfort or difficulty in breathing. In this context, the nurse is charting that the hospitalized child has labored breathing, indicating the need for further assessment and intervention to address this breathing difficulty.

Choice D rationale:

Tachypnea. Tachypnea refers to abnormally fast breathing. While it is a concern, especially in the context of a hospitalized child, it does not specifically describe labored breathing, which is the main focus of this question.
