Nokea
His head, eyes, ears, nose, and throat examinations are unremarkable. His cardiac examination is normal. On examination of his chest, the diameter seems enlarged. Breath sounds are decreased throughout all lobes. Rhonchi are heard over all lung fields. There is no area of dullness and no increased or decreased fremitus. What thorax or lung disorder is most likely causing his symptoms?
Correct Answer: B
Rationale: The patient's presentation with an enlarged chest diameter, decreased breath sounds throughout all lobes, and the presence of rhonchi over all lung fields is suggestive of a chronic condition that affects the entire respiratory system. These findings are classic for COPD, a progressive lung disease characterized by airflow limitation. The breath sounds are decreased due to airflow obstruction, and the presence of rhonchi indicates mucus production and airway inflammation commonly seen in COPD. In contrast, a spontaneous pneumothorax would typically present with sudden chest pain and shortness of breath, often in a younger patient with risk factors such as smoking. Asthma would present with wheezing, shortness of breath, and possibly a history of atopy or allergies. Pneumonia would typically present with fever, cough, and focal findings on chest examination, such as crackles or bronchial breath sounds over a consolidated area. In
