Which finding would not be expected in a child with bronchitis?

In a child with bronchitis, clear lung sounds would not be expected. Bronchitis is characterized by inflammation of the bronchial tubes, which typically leads to symptoms like cough, sputum production, and wheezing.

The presence of green sputum indicates a possible bacterial infection or high inflammatory response, which aligns with bronchial irritation. Crackles on auscultation suggest fluid presence in the airways, a common finding in bronchitis where secretions can cause abnormal lung sounds. Fever and chills are symptoms that often accompany respiratory infections, indicating the body's inflammatory response to the infection.

Therefore, clear lung sounds, which suggest unobstructed airways without fluid or secretions, would be atypical in this context, making it the correct answer as the finding that would not be expected in a child with bronchitis.
