Which treatment involves placing a device to trap emboli in the inferior vena cava?

• A. Supplemental oxygen
• B. Vasopressors
• C. Anticoagulants
• D. Vena cava filters

Answer: (D)

A vena cava filter provides a physical barrier in the inferior vena cava to catch clots traveling from the legs before they reach the lungs. This device sits in the large vein returning blood to the heart and acts like a sieve, trapping emboli so they can’t cause a pulmonary embolism. It’s especially used when anticoagulation isn’t possible due to bleeding risk or when embolic events keep occurring despite therapy. Some filters are temporary and can be removed later, while others are left in place permanently if needed. By contrast, supplemental oxygen improves oxygen levels, vasopressors support blood pressure in shock, and anticoagulants reduce clot formation without offering a mechanical barrier to catch emboli.
