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 B

Explanation

A) This choice is incorrect because while isometric exercises can promote blood flow, the recommended preventive measure for DVT is wearing graduated compression stockings. Exercises alone may not be sufficient to prevent clot formation.

B) This choice is correct. Graduated compression stockings apply pressure to the lower extremities, improving blood flow and reducing the risk of stasis and clot formation. They are commonly used as a preventive measure for clients at risk of DVT, particularly after surgery or during prolonged immobility.

C) This choice is incorrect because limiting fluid intake is not a preventive measure for DVT and may not be safe or appropriate for all clients. Adequate hydration is essential to maintain blood volume and circulation.

D) This choice is incorrect because elevating the legs while resting is a recommended measure to improve blood flow and reduce edema, which can be beneficial. However, wearing graduated compression stockings is a more specific preventive measure for DVT.

A. "Avoid foods high in vitamin K, such as leafy greens." B. "Discontinue the medication if you experience bleeding." C. "Take the medication with grapefruit juice for better absorption." D. "Do not take over-the-counter pain medications while on warfarin."

Correct Answer is A

Explanation

A) This choice is correct. Warfarin is an anticoagulant that works by inhibiting the synthesis of vitamin K-dependent clotting factors. Clients on warfarin should be advised to avoid significant fluctuations in vitamin K intake, as found in foods like leafy greens and other green vegetables, to maintain consistent anticoagulation levels.

B) This choice is incorrect because discontinuing warfarin suddenly can increase the risk of blood clot formation and other complications. Clients should follow their healthcare provider's instructions for warfarin dosing and management.

C) This choice is incorrect because taking warfarin with grapefruit juice is not recommended and may not improve medication absorption. Grapefruit juice can interfere with the metabolism of some medications, but it is not a recommended method for enhancing warfarin absorption.

D) This choice is incorrect because clients on warfarin should be cautious about taking over-the-counter pain medications, especially nonsteroidal anti-inflammatory drugs (NSAIDs), which can increase the risk of bleeding. Clients should consult their healthcare provider before taking any new medications while on warfarin.
