Answer to Question 1

C
Repeated childhood pulmonary infections can result in bronchiectasis in later life. Chronic bronchitis has similarities to bronchiectasis but is usually associated with smoking. Neither asthma nor left ventricular hypertrophy is related to bronchiectasis.

Answer to Question 2

B
An expiratory grunt is the sound generated when expired air is moving through a partially closed glottis. This partial closing of the glottis applies positive pressure against the alveoli. An increased PAO2 should result. Glottis closure will not increase vital capacity, decrease PaCO2, or close the ductus arteriosus.
