A client with reactive airway disease is tested and found to have an allergy to dust mites. The nurse determines that the client understands how to reduce her exposure to this allergen when she states which of the following?
1) "I'll run a room humidifier in my bedroom every night"
2) "Carpeting the entire house will be very expensive, but it will be worth it"
3) "Washing all the bed linens in hot water every week will be time-consuming"
4) "I'll apply insect repellent sparingly to any exposed parts when I'm outdoors"
