A client is prescribed warfarin for the treatment of deep vein thrombosis (DVT). What is the nurse's priority teaching point regarding warfarin therapy?
"You should avoid foods high in vitamin K while on warfarin."
"Warfarin will dissolve the blood clot in your leg."
"Be sure to take your warfarin dose at the same time each day."
"You can discontinue warfarin once the symptoms of DVT disappear."
The Correct Answer is A
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.

Correct Answer is B
Explanation
A) This choice is incorrect because while monitoring blood pressure is essential, it is not the priority action for clients on anticoagulant therapy. The primary concern is assessing the client's response to the medication and their risk of bleeding.
B) This choice is correct. Monitoring the client's prothrombin time (PT) and international normalized ratio (INR) is crucial in assessing the effectiveness of anticoagulant therapy. The PT and INR measure how long it takes the blood to clot and help determine the appropriate dosage of anticoagulants to achieve the desired therapeutic effect.
C) This choice is incorrect because checking the client's blood glucose levels is not directly related to monitoring the response to anticoagulant therapy. Blood glucose monitoring is essential for clients with diabetes but not a priority in this context.
D) This choice is incorrect because evaluating the client's respiratory rate and pattern is not the priority action for monitoring the response to anticoagulant therapy. Respiratory assessment is vital in detecting potential complications like a pulmonary embolism but does not directly assess the client's anticoagulation status.
Questions
Correct Answer is D
Explanation
A) This choice is incorrect because the D-dimer blood test is a screening test for DVT but does not directly assess blood flow or detect clots non-invasively.
B) This choice is incorrect because magnetic resonance imaging (MRI) is a sensitive imaging modality, but it may not be readily available or suitable for all clients. It is not the primary choice for non-invasive assessment of blood flow and clots in suspected DVT.
C) This choice is incorrect because contrast venography is an invasive procedure involving the injection of contrast dye and X-ray imaging. It is not non-invasive, and venous Doppler ultrasound is a preferred first-line test.
D) This choice is correct. Venous Doppler ultrasound is a non-invasive imaging test used to assess blood flow in the veins and detect clots in the deep veins of the legs. It is readily available, safe, and does not involve the use of contrast dye or radiation.
