A 12-month-old with excessive nasal drainage, low-grade fever, and cough for 3 days; mild wheezes on lung auscultation. Which is the most appropriate next step?

• A. Supportive care
• B. Antibiotics
• C. Bronchodilator trial
• D. Chest radiograph

Answer: (A)

When a young child shows signs consistent with a viral upper respiratory infection or bronchiolitis, the best initial approach is supportive care. The presentation described—nasal drainage, low-grade fever, cough for a few days, and only mild wheezes—fits a self-limited viral illness rather than a bacterial infection or a complication that needs testing. Antibiotics won’t help viruses and can lead to side effects and antibiotic resistance, so they’re not indicated here.

Chest radiographs are not routinely needed for uncomplicated viral illness, because most cases do not involve pneumonia and imaging doesn’t change management. Reserve radiography for when there are red flags or signs suggesting bacterial pneumonia, dehydration, severe respiratory distress, or poor feeding.

A bronchodilator trial isn’t routinely required either. In bronchiolitis and viral wheeze, evidence doesn’t show consistent benefit from albuterol or similar medications in most cases, so they’re not the default choice unless there’s a specific history of reversible airway disease or ongoing wheezing where a trial might be reasonable under careful observation.

So, the most appropriate next step is supportive care: hydration, fever and comfort measures, nasal suctioning and saline drops as needed, and close follow-up with return precautions if symptoms worsen or don’t improve over several days. If new signs develop—high fever, trouble breathing, dehydration, or poor feeding—reassess and consider further evaluation.
