Epinephrine

Which statement is accurate regarding Raynaud disease?

Episodes may be triggered by unusual sensitivity to cold.

Providing postoperative care to a patient who has percutaneous transluminal angioplasty (PTA), with insertion of a stent, for a femoral artery lesion, includes assessment for the most serious complication of:

Participate in a regular walking program.

Raynaud's disease

A physician admits a client to the health care facility for treatment of an abdominal aortic aneurysm. When planning this client's care, which goal should the nurse keep in mind as she formulates interventions?

A nurse is providing education about the prevention of arterial constriction to a client with peripheral arterial disease. Which of the following includes priority information the nurse would give to the client?

Stop smoking.

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.

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

Teach the client how to apply an elastic sleeve

A nurse and physician are preparing to visit a hospitalized client with peripheral arterial disease. As you approach the client's room, the physician asks if the client has reported any intermittent claudication. The client has reported this symptom. The nurse explains to the physician which of the following details?

The client can walk about 50 feet before getting pain in the right lower leg.

Which of the following is the most common site for a dissecting aneurysm?

Ulcers and infection in the edematous area

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

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.

The most important reason for a nurse to encourage a client with peripheral vascular disease to initiate a walking program is that this form of exercise:

decreases venous congestion.

A nurse is instructing a client about using antiembolism stockings. Antiembolism stockings help prevent deep vein thrombosis (DVT) by:

forcing blood into the deep venous system.

A pregnant client who developed deep vein thrombosis (DVT) in her right leg is receiving heparin I.V. on the medical floor.

A nursing assistant working on the medical unit helps the client with bathing, range-of-motion exercises, and personal care. Which collaborative multidisciplinary considerations should the care plan address?

The client is at risk for heparin-induced thrombocytopenia; therefore, the care plan should include reporting evidence of bleeding or easy bruising.
