A nurse is caring for a client who reports an area of redness, warmth, tenderness, and pain in the right calf.

The nurse anticipates which of the following orders when notifying the provider of this finding?

A.

Obtain impedance plethysmography.

B.

Apply cold therapy to the affected leg.

C.

Obtain a venous duplex ultrasound.

D.

Monitor Homan's sign.

Answer and Explanation

The Correct Answer is C

Choice A rationale:
Impedance plethysmography is a test that uses electrical signals to measure blood flow and can be used to detect deep vein thrombosis (DVT). However, it is not the first-line diagnostic tool for DVT.
Choice B rationale:
Cold therapy can help reduce inflammation and pain, but it is not a diagnostic measure for DVT.
Choice C rationale:
Venous duplex ultrasound is the most common test used to diagnose DVT. It uses sound waves to create pictures of the blood flowing through the veins in the leg.
Choice D rationale:
Homan’s sign is a physical examination finding that was traditionally used to diagnose DVT, but it is not reliable or specific.
