Answer to Question 1
C
Coronary aneurysm formation begins early in the second phase of Kawasaki syndrome. Coronary artery aneurysms are seen in 20 of children with untreated Kawasaki disease. Cardiac valvular disease can occur in rheumatic fever. Cardiomyopathies are diseases of the heart muscle, which can occur as a result of congenital heart disease, coronary artery disease, or other systemic disease. Rheumatic fever is not a complication of Kawasaki syndrome.

D
Arthritis, characterized by tender, warm, erythematous joints, is one of the major manifestations of rheumatic fever. The child may have had a sore throat previously associated with a group A beta-hemolytic streptococcal infection a few weeks earlier. A sore throat is not a manifestation of rheumatic fever. Hypertension is not associated with rheumatic fever. Desquamation of the fingers and toes is a manifestation of Kawasaki syndrome.
