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?

A) This choice is incorrect because regular physical activity is an essential preventive measure for DVT. Encouraging the client to engage in physical activity is vital for maintaining good circulation and reducing the risk of clot formation.

B) This choice is incorrect because a diet high in saturated fats and cholesterol is not a recommended preventive measure for DVT. A healthy, balanced diet is important for overall health, but it does not specifically prevent DVT.

C) This choice is incorrect because elevating the legs above heart level while resting is beneficial for reducing edema and improving blood flow but is not the primary preventive measure for DVT.

D) This choice is correct. The client should continue taking prescribed anticoagulant medication as directed by their healthcare provider. Anticoagulant therapy is often prescribed for a specific duration to prevent clot formation and reduce the risk of complications in clients with DVT.

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.
