A nurse is caring for a client who reports an area of redness, warmth, tenderness and pain in the right calf. Which of the following actions should the nurse anticipate when notifying the provider of this finding?

A. Obtain platelet aggregation studies. Not indicated for suspected DVT; platelet function testing is unrelated to diagnosing an acute thrombosis in the leg. B. Schedule deep tissue massage with physical therapy. Massaging a suspected DVT could dislodge a clot and precipitate pulmonary embolism. C. Arrange for a venous duplex ultrasound. Duplex venous ultrasound is the diagnostic test of choice to confirm DVT when clinical signs (redness, warmth, tenderness, swelling) suggest thrombosis. D. Monitor Homan's sign. Homan’s sign (calf pain with dorsiflexion) is neither sensitive nor specific and is no longer recommended as a reliable diagnostic maneuver; definitive imaging is required.
