When palpating the posterior chest, the clinician notes increased tactile fremitus over the left lower lobe. This can be indicative of:

D. Asthma
ANS: A
Areas of increased fremitus should raise the suspicion of conditions resulting in increased solidity or consolidation in the underlying lung tissue, such as in pneumonia, tumor, or pulmonary fibrosis. Conversely, areas of decreased fremitus raise the suspicion of abnormal fluid- or air-filled spaces, such as occurs with pleural effusion, pneumothorax, or emphysema. In the instance of an extensive bronchial obstruction, no palpable vibration is felt in the related field.
