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.
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 palpating the pulses in the extremities primarily assesses arterial blood flow, not venous thrombosis. While pulse assessment is essential, it is not the priority for identifying DVT-related manifestations.
B) This choice is correct. Measuring calf and thigh circumference can help identify possible DVT by comparing the affected leg's size to the unaffected one. DVT can cause localized swelling in the affected limb.
C) This choice is incorrect because auscultating the lungs for crackles is not a specific assessment for DVT. Crackles may be present in pulmonary edema, which can be a complication of DVT, but they do not directly assess the presence of a blood clot in the veins.
D) This choice is incorrect because performing a capillary refill test is primarily used to assess peripheral perfusion and is not specific to DVT assessment.
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.
