Pulmonary embolism is caused by a blood clot or some other particle that lodges in the pulmonary artery. What factor can make an individual predisposed to this condition?
  1. Prolonged immobilization
  2. Thrombophlebitis
  3. Atrial fibrillation
  4. All of the above
Explanation
Answer - D - Prolonged immobilization, thrombophlebitis, and atrial fibrillation all can make an individual predisposed to pulmonary embolism; certain medications can also. This condition is potentially life threatening because it can significantly decrease pulmonary blood flow, thus leading to hypoxemia. The problem occurs when a blood clot travels up the venous circulatory system and lodges in a pulmonary artery.
