Final answer:
The sign that is not a local indicator of deep vein thrombosis is tachycardia, as it is a systemic sign. Local signs of DVT include pain, tenderness, erythema, warmth, positive Homans' sign, and edema in the affected leg.
Step-by-step explanation:
The option that is NOT a local sign of deep vein thrombosis (DVT) is B. Tachycardia. This is because tachycardia, which refers to an abnormally fast heart rate, is more of a systemic sign rather than a local manifestation of DVT. Local signs of DVT typically include A. Pain, tenderness, erythema, warmth of affected leg, C. Positive Homans' sign, and D. Edema in the affected leg. The systemic signs might include shortness of breath or chest pain if the clot travels to the lungs (pulmonary embolism).
