A nurse is planning to admit a preschooler from a post-anesthesia care unit (PACU) following removal of a Wilms' tumor. Which of the following children should the nurse identify as an appropriate roommate for the preschooler?

Roommate selection for a postoperative pediatric patient requires applying principles of infection control and safety. The nurse must evaluate the risk of cross-contamination and the immune status of both children to ensure a safe environment that promotes healing and prevents complications. Choice A rationale Impetigo is a highly contagious bacterial skin infection, usually caused by Staphylococcus aureus or Streptococcus pyogenes. Placing a child with an infectious skin condition in a room with a postoperative patient increases the risk of surgical site infection. Choice B rationale A child with a fractured femur is considered "clean" because the condition is non-infectious and non-communicable. This makes them an appropriate roommate for a child recovering from major surgery like a Wilms' tumor removal. Choice C rationale Viral pneumonia is a respiratory infection that can be spread through droplets or contact. Postoperative patients are vulnerable to secondary infections, and sharing a room with an actively infected patient poses a significant respiratory health risk. Choice D rationale Cellulitis is a bacterial infection of the deep skin layers. Although not usually spread by casual contact, it is an active infection. Keeping a postoperative child away from all known infectious sources is the best practice for recovery.
