A 52-year-old patient with fatigue, pallor, anorexia, nausea, weight loss, numbness in the extremities, and foot drop most strongly suggests which disorder?

• A. Chronic renal failure
• B. Middle cerebral artery occlusion
• C. Guillain-Barre syndrome
• D. Raynaud’s phenomena

Answer: (A)

This item tests recognizing a pattern of systemic symptoms that point to kidney failure. Fatigue and pallor come from anemia due to reduced erythropoietin production in chronic kidney disease. Nausea and anorexia are common uremic symptoms as kidney function declines. As toxins build up, a uremic neuropathy can develop, leading to numbness in the extremities and weakness such as foot drop from peripheral nerve involvement. In contrast, a stroke would typically show abrupt, focal neurological deficits; Guillain-Barré presents with rapidly progressive bilateral weakness and areflexia; Raynaud’s shows color changes in fingers/toes with cold exposure. The combination of anemia, GI symptoms, and distal neuropathy most strongly points to renal failure.
