A nurse is reviewing the diagnostic workup for a client with suspected deep vein thrombosis (DVT). Which test should the nurse expect to be performed first to assess the client's risk for DVT?

D-dimer blood test.

Magnetic resonance imaging (MRI).

Complete blood count (CBC).

Wells score assessment.

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because while the D-dimer blood test is used to rule out DVT in low-risk individuals, the Wells score assessment is typically performed first to assess the client's pretest probability of DVT.

B) This choice is incorrect because magnetic resonance imaging (MRI) is not typically used as an initial diagnostic test for DVT. It may be employed in specific cases but is not the first-line test.

C) This choice is incorrect because a complete blood count (CBC) is a general blood test that does not directly assess the risk of DVT. It may provide information about overall health but is not specific to DVT assessment.

D) This choice is correct. The Wells score assessment is a validated tool used to estimate the likelihood of DVT based on clinical criteria and risk factors. It is commonly used as the first step in the diagnostic workup to determine if further testing, such as venous Doppler ultrasound or D-dimer blood test, is necessary.

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.

Questions

A. Monitoring the client's prothrombin time (PT) and international normalized ratio (INR). B. Assessing the client's liver function regularly. C. Administering heparin via a central venous catheter. D. Monitoring the client's activated partial thromboplastin time (aPTT).

Correct Answer is D

Explanation

A) This choice is incorrect because monitoring prothrombin time (PT) and international normalized ratio (INR) is more relevant to monitoring oral anticoagulant therapy (e.g., warfarin) and not intravenous heparin therapy.

B) This choice is incorrect because while liver function tests may be important for some medications, they are not the priority for clients on intravenous heparin therapy. Heparin is primarily eliminated by the kidneys.

C) This choice is incorrect because while administering heparin via a central venous catheter is possible, it is not the priority action for safe administration. Monitoring the client's response to heparin therapy is more important.

D) This choice is correct. Monitoring the client's activated partial thromboplastin time (aPTT) is the priority action when administering intravenous heparin. The aPTT reflects the client's response to heparin and helps adjust the dosage to achieve the desired therapeutic effect while minimizing the risk of bleeding.
