The nurse is monitoring a client for signs and symptoms related to superior vena cava syndrome. Which is an early sign of this oncological emergency?

  • A. Cyanosis
  • B. Arm edema
  • C. Periorbital edema
  • D. Mental status changes
Correct Answer: C

Rationale: Superior vena cava syndrome (SVCS) occurs when the superior vena cava, the large vein that carries blood from the upper body to the heart, becomes compressed or obstructed, often by a tumor or enlarged lymph nodes, typically in cancers like lung cancer or lymphoma. The obstruction leads to increased venous pressure and reduced blood flow, resulting in swelling and edema in areas drained by the superior vena cava. Periorbital edema (swelling around the eyes) is one of the earliest signs of SVCS. This occurs because the impaired venous return causes fluid to accumulate in the soft tissues of the face, especially around the eyes. As the condition progresses, facial swelling can worsen, and other symptoms develop.
