A nurse is providing education to a client at risk of deep vein thrombosis (DVT). What is the most crucial instruction the nurse should include in the client's teaching plan?

"Avoid sitting or standing in one position for extended periods."

"Massage the legs regularly to improve blood circulation."

"Increase your intake of leafy greens and foods rich in vitamin K."

"Take over-the-counter pain medications for leg discomfort."

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

A) This choice is incorrect because arterial blood gas (ABG) analysis assesses oxygen and carbon dioxide levels in the blood, primarily used for respiratory and acid-base evaluations, not for confirming DVT.

B) This choice is correct. The D-dimer blood test is a screening test used to detect the presence of blood clot breakdown products in the blood. Elevated levels of D-dimer may suggest the presence of a blood clot, prompting further diagnostic testing for DVT.

C) This choice is incorrect because an electrocardiogram (ECG) primarily assesses the electrical activity of the heart and is not specific to confirming DVT. It may be useful to assess cardiac function in individuals with suspected pulmonary embolism.

D) This choice is incorrect because a chest X-ray is not used to confirm DVT. It is helpful in assessing the lungs and heart, particularly for detecting potential complications of DVT like a pulmonary embolism, but it does not directly diagnose DVT.

A. Venous Doppler ultrasound. B. D-dimer blood test. C. Magnetic resonance imaging (MRI). D. Contrast venography.

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.
