A nurse on the pediatric unit is providing room assignments for children who are to be admitted to the unit. The nurse should plan to place a child who is postoperative from an appendectomy with which of the following clients?

A.    A child with a head injury may require close monitoring for neurological changes, which could involve frequent assessments and interventions. While not directly related to infection risk, the needs of this child may be different from those of a postoperative child, making this pairing less ideal due to differing care needs and potential disruptions. 
B.    A child in sickle cell crisis is likely experiencing significant pain and requires specialized care for pain management and hydration. This condition is not contagious but can be complex and may require frequent interventions, making it less ideal to room with a postoperative patient who needs a controlled environment for recovery.
C.    Streptococcal pharyngitis is a contagious infection caused by Group A Streptococcus. To minimize the risk of postoperative infection, it is generally advisable to avoid placing a postoperative patient in the same room with someone who has a contagious infection. This would help in preventing the potential spread of infection to the postoperative child, who is already vulnerable.
D.    A child with a new diagnosis of type 1 diabetes mellitus requires education and management of blood glucose levels. This condition is not contagious and does not pose a risk of infection to a postoperative patient. Therefore, the needs of this child align well with the postoperative child, as both are managing chronic conditions rather than dealing with infections.
