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."

Answer and Explanation

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 A

Explanation

A) This choice is correct. Prolonged sitting or standing in one position can lead to reduced blood flow and stasis, increasing the risk of DVT. Encouraging regular movement and changing positions can help prevent clot formation.

B) This choice is incorrect because massaging the legs may not be suitable for everyone and is not a primary preventive measure for DVT. While it can aid in improving blood circulation, it should be done cautiously and not as a standalone preventive action.

C) This choice is incorrect because increasing the intake of vitamin K-rich foods is not a preventive measure for DVT. Vitamin K is involved in the clotting process, but it does not directly impact the risk of DVT.

D) This choice is incorrect because taking over-the-counter pain medications for leg discomfort does not prevent DVT. While pain management may be necessary for symptomatic relief, it does not address the underlying risk factors for DVT.

A. "You should avoid eating or drinking anything for 12 hours before the test." B. "Do not take any prescribed medications on the morning of the procedure." C. "Wear loose-fitting clothing that can be easily removed." D. "Expect to receive contrast dye intravenously during the test."

Correct Answer is C

Explanation

A) This choice is incorrect because fasting is not necessary before a venous Doppler ultrasound. The client can eat and drink normally before the test.

B) This choice is incorrect because the client should continue to take prescribed medications as usual unless otherwise instructed by the healthcare provider. Medications that thin the blood, such as anticoagulants, may not be stopped before the test.

C) This choice is correct. The client should wear loose-fitting clothing that can be easily removed to allow access to the affected area during the ultrasound. This facilitates the ultrasound technician's ability to perform the test accurately.

D) This choice is incorrect because contrast dye is not typically used in a venous Doppler ultrasound. Contrast venography may involve the use of contrast dye, but not Doppler ultrasound.
