Question 1
93 of 150. An 80-year-old male with baseline heart failure edema presents with unilateral right leg erythema that is exquisitely tender, warm, and weeping fluid. He denies recent travel or surgery.
▸ Why B is the answer
Older adults with baseline edema from heart failure are at a significantly increased risk for acute bacterial skin cellulitis. When a patient develops unilateral intense warmth, exquisite tenderness, and weeping fluid, it strongly suggests an acute infection superimposed on chronic edema. An acute deep vein thrombosis certainly causes unilateral swelling, but it rarely produces the intense warmth or weeping fluid seen in this scenario. A chronic venous insufficiency flare can cause weeping, but it is typically a bilateral process and lacks the acute, exquisite tenderness described. Superficial venous thrombophlebitis presents as a firm, tender cord along a superficial vein rather than generalized weeping erythema. The unilateral inflammatory signs point directly to cellulitis.
🔑 Key takeaway
Unilateral intense warmth and tenderness in a patient with baseline edema strongly suggest superimposed bacterial cellulitis.
