A client with advanced non-small cell lung cancer is dyspneic and has a dry cough. Which oncologic complication is most likely to occur?

• A. Pleural effusion
• B. Hypercalcemia
• C. Superior vena cava syndrome
• D. Liver metastasis

Answer: (D)

In advanced non-small cell lung cancer, malignant involvement of the pleura with a malignant pleural effusion is a common cause of dyspnea. Fluid accumulating in the pleural space limits lung expansion, leading to shortness of breath, and the pleural irritation can produce a dry cough. While liver metastases are common in NSCLC, they typically cause hepatomegaly, abdominal symptoms, and weight loss rather than acute dyspnea. Hypercalcemia from bone metastases tends to cause fatigue, polyuria, dehydration, and neuro symptoms, not primarily breathing difficulties. SVC syndrome can cause dyspnea, but it’s usually accompanied by visible venous congestion and facial swelling due to obstruction. Therefore, the presentation described is most consistent with a malignant pleural effusion.
