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. 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. "Do you have a family history of high cholesterol?" B. "Have you ever been diagnosed with asthma?" C. "Have you recently traveled on a long flight?" D. "Do you take any medications for diabetes?"

Correct Answer is C

Explanation

A) This choice is incorrect because a family history of high cholesterol is not directly related to DVT risk. While high cholesterol may contribute to other cardiovascular conditions, it is not a primary risk factor for DVT.

B) This choice is incorrect because a history of asthma is not a direct risk factor for DVT. Asthma is a respiratory condition and is not significantly associated with blood clot formation.

C) This choice is correct. Prolonged immobility during long flights, especially in cramped spaces, is a known risk factor for DVT. This condition is often referred to as "economy class syndrome" due to its association with long-haul flights in tight seating.

D) This choice is incorrect because the use of medications for diabetes does not directly relate to DVT risk. While some medications may influence blood clotting, diabetes itself is not a primary risk factor for DVT.
