When is it generally recommended that a child being treated for acute streptococcal pharyngitis may return to school?

The correct answer is choice C: "Salt restriction."

Choice A rationale:

The requirement of a high protein diet is not typically indicated for a child with nephrosis. Nephrosis, a condition characterized by excessive protein in the urine, indicates a need to reduce protein intake to alleviate kidney stress and proteinuria.

Choice B rationale:

A low fat diet is not a specific requirement for a child with nephrosis. The focus in nephrosis is primarily on protein and salt intake rather than fat content.

Choice C rationale:

Salt restriction is the correct requirement for a child with nephrosis. Nephrosis often leads to fluid retention and edema due to impaired kidney function. Restricting salt intake helps to reduce fluid retention and manage blood pressure.

Choice D rationale:

A high carbohydrate diet is not commonly prescribed for a child with nephrosis. While carbohydrates are a source of energy, they are not a primary consideration in managing nephrosis. The emphasis is more on protein and salt intake.

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.
