In regards to fremitus what occurs with foreign tissues/ tumors?

• A. No vibration will be present, demonstrating no signal.
• B. Increased vibration.
• C. Strong signal.
• D. Random noise.

Answer: (A)

When evaluating tactile fremitus, you’re feeling how well voice vibrations travel from the larynx through the chest to your hands. Foreign tissue or a tumor can disrupt that transmission by replacing normal lung tissue or blocking airways, so the vibrations are not effectively conducted to the chest wall. In such cases the vibration felt is absent or greatly reduced, giving no discernible signal. This fits with the general principle that fremitus increases when tissue becomes denser and better at conducting sound (like consolidation) and decreases when the transmission path is disrupted or separated (as with air or fluid in the pleural space). A tumor or obstructing foreign tissue can create a barrier to transmission, producing no vibration over the affected area.
