Which of the following is a symptom of SVC syndrome?

• A. Upper Limb swelling
• B. Nausea
• C. Hearing Loss
• D. Abdominal pain

Answer: (A)

When the superior vena cava is blocked, blood from the head, neck, and upper limbs can’t drain properly, leading to venous congestion in those regions. This congestion causes swelling in the upper limbs, which is a classic sign of SVC syndrome. The other options don’t reflect the impaired drainage of the upper body—nausea and abdominal pain point to abdominal or GI issues, and hearing loss isn’t a typical consequence of SVC obstruction.
