Which of the following findings would suggest consolidation on examination?

Dullness to percussion and increased tactile fremitus are classic physical examination findings that suggest consolidation in the lungs, often associated with conditions such as pneumonia.

When there is consolidation, the normally air-filled alveoli in the lung are filled with fluid or solid material, which leads to a change in the physical properties of the lung tissue. Dullness to percussion occurs because the sound wave transmission is altered; the presence of fluid or solid material does not resonate as much as air does. Increased tactile fremitus is noted when a clinician palpates the chest while the patient speaks. In the case of consolidation, vibrations from the vocal cords are transmitted more effectively through the denser lung tissue, resulting in enhanced fremitus.

The other findings mentioned in the options either suggest different pulmonary conditions or do not specifically indicate the presence of consolidation. For instance, wheezing and decreased breath sounds could indicate obstructive processes rather than consolidation. Hyperresonance and stridor typically suggest conditions like pneumothorax or upper airway obstruction rather than consolidation. Cough and chest pain are symptoms that can occur in various respiratory conditions but are not definitive indicators of consolidation.
