When assessing tactile fremitus, increased tactile fremitus is expected under which condition?
asthma
emphysema
pneumothorax
acute bronchitis
pneumonia
The Correct Answer is E
A. In asthma, increased airway resistance can lead to decreased fremitus due to air trapping and poor conduction of vibrations.
B. Emphysema results in hyperinflated lungs, which typically decreases tactile fremitus because of increased air in the alveoli.
C. Pneumothorax involves air in the pleural space, leading to decreased tactile fremitus as well, since air does not conduct vibrations well.
D. Acute bronchitis can cause some changes in fremitus, but it typically does not significantly increase it.
E. Pneumonia causes consolidation of lung tissue, which increases tactile fremitus due to enhanced transmission of vibrations through solidified lung tissue.

Correct Answer is D
Explanation
A. Hyperresonance is often heard in cases of pneumothorax or emphysema, not pneumonia.
B. Bubbling is not a percussed sound but rather a description of breath sounds or fluid.
C. Tympany is typically heard over hollow organs like the stomach and is not expected in lung assessment.
D. Dullness over lung tissue indicates fluid or consolidation, as seen in pneumonia.
E. Resonance is normal over healthy lung tissue but would not be expected over areas of consolidation.
Correct Answer is C
Explanation
A. Asthma typically presents with wheezing, not fine crackles.
B. Pneumothorax usually presents with decreased or absent breath sounds rather than crackles.
C. Atelectasis, which is common after surgery, can cause fine crackles at the lung bases due to collapsed alveoli reopening during inspiration.
D. Emphysema generally results in diminished breath sounds and hyper-resonance rather than crackles.
E. Bronchitis typically produces coarse crackles or rhonchi, not fine crackles.
