Correct! Correct Answer: E. Warfarin necrosis Educational Objective: Diagnose warfarin necrosis. Critique: Warfarin necrosis may occur within the first few days of receiving large doses of warfarin. Sites of predilection include the extremities, breasts, trunk, and penis and may be the result of the rapid depletion of protein C, which induces a hypercoagulable state. |
