A nurse is assessing a client for deep vein thrombosis (DVT). Which assessment technique should the nurse prioritize to identify DVT-related clinical manifestations?
Palpating the pulses in the extremities.
Measuring calf and thigh circumference.
Auscultating the lungs for crackles.
Performing a capillary refill test.
The Correct Answer is B
A) This choice is incorrect because palpating the pulses in the extremities primarily assesses arterial blood flow, not venous thrombosis. While pulse assessment is essential, it is not the priority for identifying DVT-related manifestations.
B) This choice is correct. Measuring calf and thigh circumference can help identify possible DVT by comparing the affected leg's size to the unaffected one. DVT can cause localized swelling in the affected limb.
C) This choice is incorrect because auscultating the lungs for crackles is not a specific assessment for DVT. Crackles may be present in pulmonary edema, which can be a complication of DVT, but they do not directly assess the presence of a blood clot in the veins.
D) This choice is incorrect because performing a capillary refill test is primarily used to assess peripheral perfusion and is not specific to DVT assessment.

Correct Answer is D
Explanation
A) This choice is incorrect because compression stockings do not dissolve existing blood clots. Their primary purpose is to prevent new blood clots from forming by aiding blood flow and preventing stasis in the veins.
B) This choice is incorrect because while compression stockings may help reduce swelling in the affected leg by supporting venous return, their primary function is to prevent DVT and not specifically address swelling.
C) This choice is incorrect because compression stockings primarily target venous circulation in the legs and do not directly improve blood circulation throughout the entire body.
D) This choice is correct. Compression stockings exert pressure on the legs, assisting in venous return and preventing blood from pooling and clot formation. They are used as a preventive measure for individuals at risk of DVT or those diagnosed with DVT to reduce the risk of complications and recurrence.
Correct Answer is D
Explanation
A) This choice is incorrect because venous Doppler ultrasound is a non-invasive imaging test commonly used to diagnose DVT. However, it is not considered the gold standard due to potential limitations in visualizing small clots and deep veins.
B) This choice is incorrect because the D-dimer blood test is a screening test used to detect the presence of blood clot breakdown products. While it can help rule out DVT when negative, it is not the definitive diagnostic test.
C) This choice is incorrect because magnetic resonance imaging (MRI) is a sensitive imaging modality but is not considered the gold standard for diagnosing DVT. MRI may be used in specific cases, but contrast venography remains the gold standard.
D) This choice is correct. Contrast venography involves injecting contrast dye into the veins and taking X-ray images to visualize the blood flow and detect any clots. It is considered the gold standard for diagnosing DVT, as it provides direct visualization of the clot and the extent of its involvement.
