A nurse is caring for a client receiving intravenous (IV) heparin therapy for deep vein thrombosis (DVT). What is the nurse's priority action to ensure safe administration of the medication?

Monitoring the client's prothrombin time (PT) and international normalized ratio (INR).

Assessing the client's liver function regularly.

Administering heparin via a central venous catheter.

Monitoring the client's activated partial thromboplastin time (aPTT).

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

A) This choice is incorrect because compression stockings do not dissolve existing blood clots. Their primary purpose is to prevent new blood clots from forming by aiding blood flow and preventing stasis in the veins.

B) This choice is incorrect because while compression stockings may help reduce swelling in the affected leg by supporting venous return, their primary function is to prevent DVT and not specifically address swelling.

C) This choice is incorrect because compression stockings primarily target venous circulation in the legs and do not directly improve blood circulation throughout the entire body.

D) This choice is correct. Compression stockings exert pressure on the legs, assisting in venous return and preventing blood from pooling and clot formation. They are used as a preventive measure for individuals at risk of DVT or those diagnosed with DVT to reduce the risk of complications and recurrence.

A. "You should avoid foods high in vitamin K while on warfarin." B. "Warfarin will dissolve the blood clot in your leg." C. "Be sure to take your warfarin dose at the same time each day." D. "You can discontinue warfarin once the symptoms of DVT disappear."

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.
