In trying to differentiate between chronic bronchitis and emphysema, you know that chronic bronchitis:
1. usually occurs after age 50 and has insidious progressive dyspnea.
2. usually presents with a cough that is mild and with scant, clear sputum, if any.
3. presents with adventitious sounds, wheezing and rhonchi, and a normal percussion note.
4. results in an increased total lung capacity with a markedly increased residual volume.

The correct answer is option 3.

Explanation:

Chronic bronchitis normally occurs with respiratory infection after the age of 35 where is emphysema occurs after the age of 50. There is usually a persistent,

productive cough of copious mucopurulent sputum where is in emphysema there is no cough or scant if any high breathing sound.

Thus, the correct answer is option 3.
