Answer to Question 1

ANS: D
Several conditions enhance the intravascular coagulability of the blood and predispose to venous thromboembolic disease (Box 28-1). The most frequent causes of an inherited hypercoagulable state are the factor V Leiden mutation and the prothrombin gene mutation, which together ac-count for 50 to 60 of cases. The major acquired risk factors for VTE include recent major surgery, trauma, immobilization, antiphospholipid antibody syndrome, malignancy, pregnancy, oral contraceptives, and myeloproliferative disorders. Vessel wall abnormalities are found most often in patients who have sustained trauma or have undergone major surgery.

Answer to Question 2

ANS: C
Tension pneumothorax occurs when air in the pleural space exceeds atmospheric pressure. The radiographic appearance includes mediastinal shift to the contralateral side, diaphragmatic de-pression, and expansion of the ribs.
