Which finding is an indication for chest radiography in suspected bronchitis?

• A. Bloody sputum
• B. Normal exam with no symptoms
• C. No fever
• D. Cough lasting less than 24 hours

Answer: (A)

When assessing suspected bronchitis, look for red flags that would prompt imaging. The key signal here is blood in the sputum. Hemoptysis raises concern for pneumonia or other lung pathology (eg, tuberculosis, bronchiectasis, malignancy) that an chest radiograph can help evaluate by showing focal infiltrates or other abnormalities. In contrast, a normal exam with no symptoms, no fever, or a very short cough duration does not by itself indicate radiography, since most acute bronchitis cases are viral and self-limited.
