A nurse is caring for a client with chronic venous insufficiency (CVI). Which intervention should the nurse include in the client's plan of care?

A) This choice is incorrect because encouraging prolonged standing can worsen symptoms of chronic venous insufficiency (CVI). Prolonged standing increases venous pressure in the legs and can lead to further swelling and discomfort.

B) This choice is correct. Elevating the legs above heart level when resting is a beneficial intervention for individuals with chronic venous insufficiency (CVI). Elevating the legs helps improve venous return and reduces swelling in the legs.

C) This choice is incorrect because applying warm compresses to the legs may provide temporary relief for some individuals, but it is not a primary intervention for managing chronic venous insufficiency (CVI).

D) This choice is incorrect because tight-fitting compression stockings are commonly used to manage chronic venous insufficiency (CVI), but they should be fitted appropriately by a healthcare professional. Wearing overly tight compression stockings can impede blood flow and cause discomfort.

A) This choice is incorrect because arteriography is an invasive procedure that involves the insertion of a catheter through a blood vessel, typically in the groin or arm, to inject contrast dye directly into the arteries. It is not performed using a small incision in the leg.

B) This choice is incorrect because keeping the leg immobile after an arteriography is not necessary. However, the client will be asked to rest and avoid strenuous activities for a few hours following the procedure.

C) This choice is incorrect because the procedure that uses sound waves to visualize blood flow is a Doppler ultrasound, not an arteriography. Arteriography involves the use of contrast dye and X-rays to visualize the arterial blood vessels.

D) This choice is correct. Arteriography requires the use of contrast dye to enhance the visualization of blood vessels during X-ray imaging. There is a risk of an allergic reaction to the contrast dye, and clients should be informed about this potential complication before the procedure. Precautions may be taken, and the client's medical history should be reviewed to identify any contraindications to the use of contrast dye.
