Correct answer: B — Provide supportive care with hydration advice and monitoring

Typical bronchiolitis is managed supportively, with attention to hydration, oxygen need and work of breathing. Routine bronchodilators, steroids and antibiotics are not recommended for uncomplicated bronchiolitis. Chest x-ray is reserved for atypical or severe presentations because it can lead to unnecessary antibiotics.
