Correct answer: D — Provide supportive care without routine bronchodilators or antibiotics

Provide supportive care without routine bronchodilators or antibiotics is the single best answer because the age, timing, examination findings and investigations in the vignette fit Bronchiolitis better than the alternatives. The most tempting distractor is less appropriate because it either treats a neighbouring presentation, delays a time-critical intervention, or ignores a key discriminator in the stem. The remaining options are suboptimal because they would miss the diagnosis, use an investigation or treatment in the wrong sequence, or fail to address safety and follow-up. Canadian practice should be anchored to CPS bronchiolitis statement, with attention to acuity, safety-netting and local provincial pathways.
