A client is scheduled for a venous Doppler ultrasound to assess for deep vein thrombosis (DVT). What instructions should the nurse provide to the client before the procedure?

"You should avoid eating or drinking anything for 12 hours before the test."

"Do not take any prescribed medications on the morning of the procedure."

"Wear loose-fitting clothing that can be easily removed."

"Expect to receive contrast dye intravenously during the test."

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

A) This choice is incorrect because mild leg swelling after prolonged standing may be expected, especially in clients with a history of DVT. It is not a critical symptom to report immediately.

B) This choice is correct. Redness and warmth at the site of the affected leg could indicate an inflammatory response or progression of the clot. These signs may be indicative of a potential complication, such as an infection or extension of the clot, and should be reported immediately for further evaluation and intervention.

C) This choice is incorrect because occasional cramping in the unaffected leg may not be directly related to the DVT. While any changes in leg symptoms should be reported to the healthcare provider, this symptom is less urgent than redness and warmth in the affected leg.

D) This choice is incorrect because mild fatigue and generalized body aches are non-specific symptoms and may not be directly related to DVT. While it is essential to report any new or concerning symptoms, redness and warmth in the affected leg are more indicative of potential complications related to DVT.

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.
