The sign that you would expect to see on the chest x-ray is consolidation, indicated by opaque patches or shadows in the lungs. This signifies a condition such as pneumonia, which is characterized by the filling of the air sacs in the lungs with fluid or mucus. In the given patient's case, the symptoms of dyspnea, fatigue, and cough with frothy white sputum, along with physical exam findings such as jugular vein distension and pitting edema, are indicative of congestive heart failure.
