A child is admitted to the pediatric unit with a diagnosis of Kawasaki disease. Which nursing intervention is most appropriate during this initial phase?

A. Administering antibiotics is not appropriate as Kawasaki disease is not caused by a bacterial infection; it is an inflammatory condition. B. While monitoring for signs of coronary artery aneurysms is essential, the immediate intervention needed in the initial phase is to administer IVIG to mitigate inflammation and prevent complications. C. Providing comfort measures for peeling skin is supportive but does not address the critical treatment needs in Kawasaki disease. D. Administering intravenous immunoglobulin (IVIG) is the priority nursing intervention as it helps reduce inflammation and the risk of developing cardiovascular complications associated with Kawasaki disease.
