A nurse is caring for a client with suspected deep vein thrombosis (DVT). Which diagnostic test is used to assess blood flow and detect clots in the deep veins of the legs non-invasively?

D-dimer blood test.

Magnetic resonance imaging (MRI).

Contrast venography.

Venous Doppler ultrasound.

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because the D-dimer blood test is a screening test for DVT but does not directly assess blood flow or detect clots non-invasively.

B) This choice is incorrect because magnetic resonance imaging (MRI) is a sensitive imaging modality, but it may not be readily available or suitable for all clients. It is not the primary choice for non-invasive assessment of blood flow and clots in suspected DVT.

C) This choice is incorrect because contrast venography is an invasive procedure involving the injection of contrast dye and X-ray imaging. It is not non-invasive, and venous Doppler ultrasound is a preferred first-line test.

D) This choice is correct. Venous Doppler ultrasound is a non-invasive imaging test used to assess blood flow in the veins and detect clots in the deep veins of the legs. It is readily available, safe, and does not involve the use of contrast dye or radiation.

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.

Questions

A. "Avoid sitting or standing in one position for extended periods." B. "Massage the legs regularly to improve blood circulation." C. "Increase your intake of leafy greens and foods rich in vitamin K." D. "Take over-the-counter pain medications for leg discomfort."

Correct Answer is A

Explanation

A) This choice is correct. Prolonged sitting or standing in one position can lead to reduced blood flow and stasis, increasing the risk of DVT. Encouraging regular movement and changing positions can help prevent clot formation.

B) This choice is incorrect because massaging the legs may not be suitable for everyone and is not a primary preventive measure for DVT. While it can aid in improving blood circulation, it should be done cautiously and not as a standalone preventive action.

C) This choice is incorrect because increasing the intake of vitamin K-rich foods is not a preventive measure for DVT. Vitamin K is involved in the clotting process, but it does not directly impact the risk of DVT.

D) This choice is incorrect because taking over-the-counter pain medications for leg discomfort does not prevent DVT. While pain management may be necessary for symptomatic relief, it does not address the underlying risk factors for DVT.
