  d. LTB

Answer to Question 1

D
All of the listed clinical signs indicate a diagnosis of LTB. The other conditions would have a different mix of signs.

Answer to Question 2

D
Because polycythemia and cor pulmonale are associated with severe bronchiectasis, the following may be seen: distended neck veins, pitting edema, and enlarged and tender liver. The S3 heart sound is associated with congestive heart failure. There would be no reason to suspect this in a patient with bronchiectasis.
