A nurse is reviewing self-care measures for a client with peripheral vascular disease. Which statement indicates proper self-care measures?

"I have my wife look at the soles of my feet every day" A client with peripheral vascular disease should examine his feet daily for redness, dryness, or cuts. If a client isn't able to do this examination on his own, then a caregiver or family member should help him. A client with peripheral vascular disease should avoid hot tubs because decreased sensation in the feet may make him unable to tell if the water is too hot. The client should always wear shoes or slippers on his feet when he is out of bed to help minimize trauma to the feet. Any type of nicotine, whether it's from cigarettes or smokeless tobacco, can cause vasoconstriction and further decrease blood supply to the extremities.

A client admitted to the medical-surgical unit with a venous thromboembolism (VTE) is started on enoxaparin and warfarin. The client asks the nurse why two medications are needed. Which response by the nurse is accurate?

"The enoxaparin will work immediately, but the warfarin takes several days to achieve its full effect." Oral anticoagulants such as warfarin are monitored by the prothrombin time (PT) or the international normalized ratio (INR). Because the full anticoagulant effect of warfarin is delayed for 3 to 5 days, it is usually administered concurrently with heparin until desired anticoagulation has been achieved (i.e., when the PT is 1.5 to 2 times normal or the INR is 2.0 to 3.0).

When administering heparin anticoagulant therapy, the nurse needs to make certain that the activated partial thromboplastin time (aPTT) is within the therapeutic range of:

1.5 to 2.5 times the baseline control. A normal PTT level is 21 to 35 seconds. A reading of more than 100 seconds indicates a significant risk of hemorrhage.

Which of the following is the hallmark symptom for peripheral arterial disease (PAD) in the lower extremity?

>>> Intermittent claudication <<< The hallmark symptom of PAD in the lower extremity is intermittent claudication. This pain may be described as aching or cramping in a muscle that occurs with the same degree of exercise or activity and is relieved with rest.

You are presenting a workshop at the senior citizens center about how the changes of aging predisposes clients to vascular occlusive disorders. What would you name as the most common cause of peripheral arterial problems in the older adult?

Atherosclerosis Atherosclerosis is the most common cause of peripheral arterial problems in the older adult. Therefore, options A, B, and D are incorrect.

The term for a diagnostic test that involves injection of a contrast media into the venous system through a dorsal vein in the foot is

Contrast phlebography When a thrombus exists, an X-ray image will disclose an unfilled segment of a vein. Air plethysmography quantifies venous reflux and calf muscle pump ejection. In lymphangiography, contrast media are injected into the lymph system. In lymphoscintigraphy, a radioactive-labeled colloid is injected into the lymph system.

The nurse is assessing a patient with suspected acute venous insufficiency. What clinical manifestations would indicate this condition to the nurse? (Select all that apply.)

Cool and cyanotic skin Sharp pain that may be relieved by the elevation of the extremity Full superficial veins Postthrombotic syndrome is characterized by chronic venous stasis, resulting in edema, altered pigmentation, pain, and stasis dermatitis. The patient may notice the symptoms less in the morning and more in the evening. Obstruction or poor calf muscle pumping in addition to valvular reflux must be present for the development of severe postthrombotic syndrome and stasis ulcers. Superficial veins may be dilated.

Which is a characteristic of arterial insufficiency?

Diminished or absent pulses A diminished or absent pulse is a characteristic of arterial insufficiency. Venous characteristics include superficial ulcer formation, an aching and cramping pain, and presence of pulses

A client with venous insufficiency asks the nurse what they can do to decrease their risk of complications. What advice should the nurse provide to clients with venous insufficiency?

Elevate the legs periodically for at least 15 to 20 minutes. The nurse should advise the client to periodically elevate the legs for at least 15 to 20 minutes. Avoiding foods with iodine or refraining from sexual activity for a week does not relate to venous insufficiency.

A client with lower extremity edema is diagnosed with lymphedema. For which medication will the nurse prepare teaching for this client?

Furosemide Lymphedema may be primary (congenital malformations) or secondary (acquired obstructions). Tissue swelling occurs in the extremities because of an increased quantity of lymph that results from obstruction of lymphatic vessels. As initial therapy, the diuretic furosemide may be prescribed to prevent fluid overload due to mobilization of extracellular fluid. Opioids are not used to treat lymphedema. Antibiotics would be prescribed only if an infection is present. Anticoagulants are not used to treat lymphedema.

Which term refers to enlarged, red, and tender lymph nodes?

Lymphadenitis Acute lymphadenitis is demonstrated by enlarged, red, and tender lymph nodes. Lymphangitis is acute inflammation of the lymphatic channels. Lymphedema is demonstrated by swelling of tissues in the extremities because of an increased quantity of lymph that results from an obstruction of lymphatic vessels. Elephantiasis refers to a condition in which chronic swelling of the extremity recedes only slightly with elevation.

A client is diagnosed with peripheral arterial disease. Review of the client's chart shows an ankle-brachial index (ABI) on the right of 0.45. This indicates that the right foot has which of the following?

Moderate to severe arterial insufficiency Normal people without arterial insufficiency have an ABI of about 1.0. Those with an ABI of 0.95 to 0.5 have mild to moderate arterial insufficiency. Those with an ABI of less than 0.50 have ischemic rest pain. Those with tissue loss have severe ischemia and an ABI of 0.25 or less.

A nurse is assessing a client's right lower leg, which is wrapped with an elastic bandage. Which signs and symptoms suggest circulatory impairment?

Numbness, cool skin temperature, and pallor Signs and symptoms of impaired circulation include numbness and cool, pale skin. Signs of localized infection may include swelling, drainage, redness, and warm skin. Signs of adequate circulation include normal sensation and warm skin with normal return of skin color after blanching.

What should the nurse do to manage persistent swelling in a client with severe lymphangitis and lymphadenitis?

Teach the client how to apply a graduated compression stocking. In severe cases of lymphangitis and lymphadenitis with persistent swelling, the nurse teaches the client how to apply a graduated compression stocking. The nurse informs the physician if the client's temperature remains elevated. The nurse recommends elevating the area to reduce the swelling and provides warmth to promote comfort and to enhance circulation.

A home health nurse is seeing an elderly male client for the first time. During the physical assessment of the skin on the lower legs, the nurse notes edema, brown pigmentation in the gaiter area, pedal pulses, and a few irregularly shaped ulcers around the ankles. From these findings, the nurse knows that the client has a problem with peripheral circulation. Which of the following does the nurse suspect?

Venous insufficiency Symptoms of venous insufficiency include present pedal pulses, edema, pigmentation in gaiter area, and a reddish blue color. Ulcers caused by venous insufficiency will be irregular in shape and usually located around the ankles or the anterior tibial area. Characteristics of arterial insufficiency ulcers include location at the tips of the toes, great pain, and circular shape with a pale to black ulcer base.
