Answer to Question 1

ANS: B
A pleural friction rub is a creaking or grating sound that occurs when the pleural surfaces become inflamed and the roughened edges rub together during breathing, as in pleurisy. It may be heard only during inhalation but often is identified during both phases of breathing.

Answer to Question 2

ANS: D
Early inspiratory crackles are usually scanty but may be loud or faint. They often are transmitted to the mouth and are not silenced by a cough or a change in position. They most often occur in patients with COPD, such as chronic bronchitis, emphysema, or asthma, and usually indicate a severe airway obstruction.
