A nurse is planning care for a 4-year-old child who requires airborne precautions. Which of the following activities should the nurse plan for the child?

The correct answer is C: Putting a large-piece puzzle together. Airborne precautions are used to prevent the spread of infectious agents that are transmitted through the air. Constructing a model airplane (choice A) involves handling small pieces and may generate dust particles, increasing the risk of spreading infection. Pulling a wagon with toys in the hallway (choice B) involves moving around and interacting with others, potentially spreading the infection. Watching a video game in the playroom (choice D) may lead to close contact with other children, again increasing the risk of transmission. Putting a large-piece puzzle together (choice C) is a solitary activity that does not involve close contact with others, making it the most appropriate choice for a child requiring airborne precautions.
