A nurse is explaining the diagnostic tests for deep vein thrombosis (DVT) to a client. Which test is considered the gold standard for diagnosing DVT?
Venous Doppler ultrasound.
D-dimer blood test.
Magnetic resonance imaging (MRI).
Contrast venography.
The Correct Answer is D
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.

Related Questions
Correct Answer is B
Explanation
A) This choice is incorrect because mild leg swelling after prolonged standing may be expected, especially in clients with a history of DVT. It is not a critical symptom to report immediately.
B) This choice is correct. Redness and warmth at the site of the affected leg could indicate an inflammatory response or progression of the clot. These signs may be indicative of a potential complication, such as an infection or extension of the clot, and should be reported immediately for further evaluation and intervention.
C) This choice is incorrect because occasional cramping in the unaffected leg may not be directly related to the DVT. While any changes in leg symptoms should be reported to the healthcare provider, this symptom is less urgent than redness and warmth in the affected leg.
D) This choice is incorrect because mild fatigue and generalized body aches are non-specific symptoms and may not be directly related to DVT. While it is essential to report any new or concerning symptoms, redness and warmth in the affected leg are more indicative of potential complications related to DVT.
Questions
Correct Answer is C
Explanation
A) This choice is incorrect because fasting is not necessary before a venous Doppler ultrasound. The client can eat and drink normally before the test.
B) This choice is incorrect because the client should continue to take prescribed medications as usual unless otherwise instructed by the healthcare provider. Medications that thin the blood, such as anticoagulants, may not be stopped before the test.
C) This choice is correct. The client should wear loose-fitting clothing that can be easily removed to allow access to the affected area during the ultrasound. This facilitates the ultrasound technician's ability to perform the test accurately.
D) This choice is incorrect because contrast dye is not typically used in a venous Doppler ultrasound. Contrast venography may involve the use of contrast dye, but not Doppler ultrasound.
