A nurse is assessing a patient who is at risk for deep-vein thrombosis (DVT). Which of the following findings is a manifestation of DVT?

Choice A reason: A bruit over a pedal pulse suggests arterial turbulence, not venous thrombosis. DVT involves clot formation in deep veins, typically causing swelling, warmth, and tenderness, not arterial sounds. Auscultation is irrelevant for DVT, as it does not affect arterial flow or produce vascular sounds. Choice B reason: Pallor in the affected extremity is associated with arterial occlusion, not DVT. DVT causes venous congestion, leading to swelling, redness, or warmth due to impaired venous return, not reduced arterial perfusion. Pallor indicates ischemia, which is inconsistent with the pathophysiology of venous thrombosis. Choice C reason: Groin tenderness is a manifestation of DVT, particularly in proximal veins like the femoral vein. Clot formation causes inflammation, leading to localized pain and tenderness. This symptom, often accompanied by swelling, is a key clinical sign, prompting further evaluation like ultrasound to confirm DVT. Choice D reason: Cramping pain in one foot is more suggestive of muscle strain or neuropathy. DVT typically presents with diffuse swelling, warmth, and tenderness in the calf or thigh, not localized foot cramping. This symptom lacks specificity for DVT and is less likely to indicate venous thrombosis.
