The nurse is teaching a group of staff nurses about risk factors associated with developing a pulmonary embolism. Which of the following conditions would the nurse include in the teaching? Select all that apply

A. Thrombophlebitis is inflammation of a vein with clot formation, often in the lower extremities. These clots can dislodge and travel to the lungs, causing a pulmonary embolism (PE). B. Pregnancy increases the risk of PE due to hypercoagulability, venous stasis from uterine pressure on pelvic veins, and hormonal changes that promote clot formation. C. Major orthopedic procedures, particularly hip, knee, and pelvic surgeries, are associated with prolonged immobility and endothelial injury, increasing the risk for deep vein thrombosis (DVT) and subsequent PE. D. Diabetes increases risk for cardiovascular disease, but it is not a primary risk factor for pulmonary embolism. While microvascular complications exist, they do not directly cause clot formation leading to PE. E. Myocardial infarction involves coronary artery occlusion, which can increase thrombotic risk in coronary vessels, but it is not a direct risk factor for pulmonary embolism.
