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.

Answer and Explanation

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.

Correct Answer is A

Explanation

A) This choice is correct. Gender is a non-modifiable risk factor for DVT, with women generally having a higher risk than men. Hormonal changes, such as those associated with pregnancy, oral contraceptives, and hormone replacement therapy, can contribute to the increased risk in women.

B) This choice is incorrect because obesity is a modifiable risk factor for DVT, not a non-modifiable one. Clients can work to achieve and maintain a healthy weight to reduce their risk.

C) This choice is incorrect because smoking history is a modifiable risk factor for DVT. Clients can quit smoking to decrease their risk of blood clot formation.

D) This choice is incorrect because a sedentary lifestyle is a modifiable risk factor for DVT. Clients can engage in regular physical activity to reduce their risk.

A. Advanced age B. Male gender C. Smoking history D. Hormonal therapy

Correct Answer is D

Explanation

A) This choice is incorrect because advanced age is a non-modifiable risk factor for DVT. While age is associated with increased risk, it is not directly related to the client's use of hormonal therapy.

B) This choice is incorrect because male gender is not a risk factor for DVT. Women, particularly those on estrogen-based therapies like hormone replacement therapy or oral contraceptives, are at higher risk.

C) This choice is incorrect because smoking history is a modifiable risk factor for DVT, not directly related to hormonal therapy. Smoking increases the risk of clot formation and is not specific to the client's use of hormonal therapy.

D) This choice is correct. Estrogen-based hormone replacement therapy and oral contraceptives can increase the risk of DVT due to their effect on blood coagulation. Estrogen can increase the production of certain clotting factors, raising the risk of blood clot formation in the veins. It is essential for healthcare providers to weigh the benefits and risks when prescribing hormonal therapy to clients.
