Correct answer: C — Start IVIG and antiplatelet therapy while arranging echocardiography

The best answer is “Start IVIG and antiplatelet therapy while arranging echocardiography”. This meets clinical criteria for Kawasaki disease. Canadian Paediatric Society guidance recommends one IVIG dose of 2 g/kg followed by daily antiplatelet therapy; echocardiography is essential but must not delay treatment. Waiting for coronary change, treating as bacterial infection alone or using supportive care risks preventable coronary injury.
