A. Immunoglobulin E is involved in allergic reactions and is not used in the treatment of Kawasaki disease. Heparin is an anticoagulant and not typically indicated in KD treatment. B. Immunoglobulin G is used in KD, but ACE inhibitors are not part of the standard treatment regimen for this condition. C. Immunoglobulin E is incorrect, and while ibuprofen is an NSAID, aspirin is preferred in Kawasaki disease due to its antiplatelet and anti-inflammatory properties. D. The standard treatment for Kawasaki disease includes intravenous immunoglobulin G (IVIG) and aspirin. IVIG helps reduce inflammation and the risk of coronary artery aneurysms, while aspirin reduces fever, inflammation, and prevents blood clots.
