1. General Principles & Basic Science MCQs

C ardinal signs of evenomation include all of the following except:

A 24-year-old man presents to the emergency department. He was bitten on his fist while fighting with another man. You notice teeth marks on the dorsum of the metacarpophalangeal (MC P) joint of the right middle finger. The bite does not appear to be deep because the joint is not exposed, and you can see the extensor tendon, which seems intact. The patient has active extension at the MC P joint. The wound is red and swollen, but there is no tenderness or redness on the volar aspect of the MCP joint. The patient has some limitation in range of motion. He is afebrile. Radiographs reveal soft tissue involvement but no joint dislocation or fracture, and there is no neurovascular deficit. An important step in assessment of human bites is:
