A nurse is caring for a school-age child who had a tonic-clonic seizure 1 min ago. Which of the following actions should the nurse take?

Choice A rationale:
Washing the child's pillow in cold water twice monthly is not a relevant instruction for controlling allergens in asthma management. Asthma triggers are often related to airborne allergens such as dust mites, pollen, and pet dander, and focusing on pillow washing alone does not address the broader issue of allergen exposure.
Choice B rationale:
Using a humidifier in the child's bedroom can actually worsen asthma symptoms. Humidifiers can increase the humidity in the air, promoting the growth of mold and dust mites, which are common allergens that can trigger asthma symptoms. Therefore, this instruction is not appropriate for asthma management.
Choice C rationale:
This is the correct answer. Using a damp cloth to dust the child's furniture weekly is a relevant instruction for controlling allergens. Dusting with a damp cloth helps to capture and remove allergens such as dust mites, pollen, and pet dander from surfaces, reducing the child's exposure to these triggers and potentially minimizing asthma symptoms.
Choice D rationale:
Installing carpet in the child's bedroom is not recommended for asthma management. Carpets can harbor dust mites, mold, and other allergens that can exacerbate asthma symptoms. Hard flooring surfaces that can be easily cleaned and do not trap allergens are a better choice for individuals with asthma.

Choice A rationale:
This statement reflects an accurate understanding of varicella (chickenpox) transmission and infection control. The lesions of varicella contain the virus and are contagious until they have crusted over. Allowing the child to go to the playroom only after the lesions have crusted helps prevent the spread of the virus to other individuals.
Choice B rationale:
This statement is incorrect because waiting for the crusts to fall off the lesions before bathing the child is not necessary. In fact, keeping the lesions clean and maintaining proper hygiene through gentle bathing can help prevent secondary bacterial infections.
Choice C rationale:
This statement is incorrect because bedrest for 3 days is not necessary for a child with varicella. While it's important to minimize contact with others during the contagious phase, physical activity can be gradually resumed as long as the lesions have crusted to prevent transmission.
Choice D rationale:
This statement is incorrect. Once a person has had chickenpox (varicella), they develop immunity to the virus and do not need to wear a mask when visiting someone with active varicella. This is because they are already immune to the virus due to their prior infection.
