A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin) as an anticoagulant. What should the nurse include in the client's education about warfarin therapy?

"Avoid foods high in vitamin K, such as leafy greens."

"Discontinue the medication if you experience bleeding."

"Take the medication with grapefruit juice for better absorption."

"Do not take over-the-counter pain medications while on warfarin."

Answer and Explanation

The Correct Answer is A

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.

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.

A. Advanced age B. Male gender C. Smoking history D. Hormonal therapy

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.
