Which preexisting diagnosis places a client at greatest risk of developing superior vena cava syndrome?

• A. Carotid stenosis.
• B. Steatosis hepatitis.
• C. Metastatic cancer.
• D. Clavicular fracture.

Answer: (C)

Superior vena cava syndrome happens when the superior vena cava is obstructed, most often by a tumor growing in the chest or by pressure from enlarged lymph nodes. This blockage prevents blood from the head, neck, and upper chest from returning to the heart, leading to facial and upper-extremity swelling, prominent chest veins, and sometimes shortness of breath. Metastatic cancer carries the greatest risk because it can spread to the mediastinum or form chest tumors that directly compress or invade the SVC, making obstruction more likely. The other conditions involve different vessels or organs and do not typically cause this chest-wide venous obstruction.
