A client with a history of deep vein thrombosis (DVT) asks the nurse about the causes of this condition. What is the nurse's best response?

"DVT is caused by a bacterial infection in the blood vessels."

"The exact cause of DVT is unknown, but it can be triggered by injuries."

"DVT is primarily caused by atherosclerosis in the arteries."

"The formation of blood clots in the veins is the main cause of DVT."

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because DVT is not caused by a bacterial infection in the blood vessels. It is primarily related to the formation of blood clots within the veins due to various risk factors.

B) This choice is incorrect because while injuries may be associated with DVT in some cases, they are not the primary cause. The formation of blood clots in the veins remains the underlying cause.

C) This choice is incorrect because atherosclerosis in the arteries is not the main cause of DVT. Atherosclerosis is a condition that involves the buildup of plaque in the arteries, not the veins.

D) This choice is correct. Deep vein thrombosis (DVT) is primarily caused by the formation of blood clots within the veins, typically in the lower extremities. These clots can obstruct blood flow and may lead to serious complications if not treated promptly.

Correct Answer is A

Explanation

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.

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.
