A nurse is caring for a client who is postoperative. For which of the following findings should the nurse suspect the client is experiencing a deep vein thrombosis?

A. Absent pedal pulse: Deep vein thrombosis affects the venous system, so arterial pulses typically remain palpable. An absent pulse is more indicative of arterial occlusion rather than DVT. Monitoring pulses is important, but this finding does not confirm DVT. B. Numbness of the affected extremity: Numbness is usually associated with nerve compression or neuropathy, not DVT. While swelling from a clot may occasionally cause mild pressure on nerves, sensory changes are not a primary diagnostic indicator of venous thrombosis. C. Warmth of the affected extremity: Localized warmth, along with redness, swelling, and tenderness, is a classic sign of DVT due to inflammation and venous obstruction. This finding warrants prompt assessment and intervention to prevent complications such as pulmonary embolism. D. Muscle spasms: Muscle cramps or spasms may occur for various reasons, including electrolyte imbalances, but they are not specific indicators of DVT. Relying on spasms alone could delay appropriate diagnosis and treatment.
