A client is admitted to the hospital with symptoms suggestive of deep vein thrombosis (DVT). Which test can provide rapid results to rule out DVT and guide further diagnostic workup?

D-dimer blood test.

Contrast venography.

Magnetic resonance imaging (MRI).

Wells score assessment.

Answer and Explanation

The Correct Answer is A

A) This choice is correct. The D-dimer blood test is a rapid and sensitive screening test that can help rule out DVT in low-risk individuals. A negative D-dimer result can be useful in excluding DVT, avoiding unnecessary imaging or invasive tests.

B) This choice is incorrect because contrast venography is not a rapid test and involves invasive procedures. It is not used as a first-line screening test due to its complexity and potential risks.

C) This choice is incorrect because magnetic resonance imaging (MRI) may provide valuable information, but it is not the first choice for rapid rule-out of DVT. MRI may be employed in specific cases when initial screening tests are inconclusive.

D) This choice is incorrect because the Wells score assessment is not a diagnostic test but a scoring system to estimate the likelihood of DVT. It does not provide rapid results to rule out DVT directly.

Correct Answer is A

Explanation

A) This choice is correct. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Consistent vitamin K intake can impact the effectiveness of warfarin, so it is important for clients to maintain a stable vitamin K intake and avoid sudden changes in their diet.

B) This choice is incorrect because warfarin does not directly dissolve the blood clot in the leg. It prevents the formation of new clots and allows the body's natural mechanisms to dissolve the existing clot over time.

C) This choice is incorrect because while taking warfarin at the same time each day can help with adherence, the priority teaching point is about vitamin K intake and not the exact timing of the medication.

D) This choice is incorrect because discontinuing warfarin without medical guidance can be dangerous. Warfarin is typically prescribed for a specific duration, and its cessation should be guided by the healthcare provider based on the client's individual condition and risk factors.

A. "Anticoagulants help dissolve existing blood clots in the veins." B. "These medications prevent the formation of new blood clots in your veins." C. "They reduce pain and inflammation associated with DVT." D. "Anticoagulants improve blood flow to the affected limb."

Correct Answer is B

Explanation

A) This choice is incorrect because anticoagulants do not dissolve existing blood clots in the veins. They prevent further clot formation and allow the body's natural mechanisms to dissolve the clot over time.

B) This choice is correct. Anticoagulants work by inhibiting the clotting factors in the blood, which prevents the formation of new blood clots and reduces the risk of the existing clot enlarging or causing additional complications.

C) This choice is incorrect because while anticoagulants may indirectly reduce pain and inflammation by preventing further clot formation, their primary action is to prevent clotting, not directly reduce pain and inflammation associated with DVT.

D) This choice is incorrect because while anticoagulants can improve blood flow by preventing clot formation, they do not directly "improve" blood flow to the affected limb.
