DIF:    Recall             REF:   p. 581            OBJ:   1

3. Which of the following risk factors is NOT associated with an increase in the incidence of pulmonary embolism?

ANS:  D

Several conditions enhance the intravascular coagulability of the blood and predispose to venous thromboembolic disease (Box 26-1). The most frequent causes of an inherited hypercoagulable state are the factor V Leiden mutation and the prothrombin gene mutation, which together account for 50-60% of cases. The major acquired risk factors for VTE include recent major surgery, trauma, immobilization, antiphospoholipid antibody syndrome, malignancy, pregnancy, oral contraceptives, and myeloproliferative disorders.

The major acquired risk factors for VTE include recent major surgery, trauma, immobilization, antiphospoholipid 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.
