A nurse in a long-term care facility is caring for an 83-year-old woman who has a history of HF and peripheral arterial disease (PAD). At present the patient is unable to stand or ambulate. The nurse should implement measures to prevent what complication?
- A. Aoritis
- B. Deep vein thrombosis
- C. Thoracic aortic aneurysm
- D. Raynauds disease
Correct Answer: B
Rationale: Although the exact cause of venous thrombosis remains unclear, three factors, known as Virchows triad, are believed to play a significant role in its development: stasis of blood (venous stasis), vessel wall injury, and altered blood coagulation. In this womans case, she has venous stasis from immobility, vessel wall injury from PAD, and altered blood coagulation from HF. The cause of aoritis is unknown, but it has no direct connection to HF, PAD, or mobility issues. The greatest risk factors for thoracic aortic aneurysm are atherosclerosis and hypertension; there is no direct connection to HF, PAD, or mobility issues. Raynauds disease is a disorder that involves spasms of blood vessels and, again, no direct connection to HF, PAD, or mobility issues.

The clinic nurse is caring for a 57-year-old client who reports experiencing leg pain whenever she walks several blocks. The patient has type 1 diabetes and has smoked a pack of cigarettes every day for the past 40 years. The physician diagnoses intermittent claudication. The nurse should provide what instruction about long-term care to the client?
- A. Be sure to practice meticulous foot care.
- B. Consider cutting down on your smoking.
- C. Reduce your activity level to accommodate your limitations.
- D. Try to make sure you eat enough protein.
Correct Answer: A
Rationale: The patient with peripheral vascular disease or diabetes should receive education or reinforcement about skin and foot care. Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing; therefore, meticulous foot care is essential. The patient should stop smokingnot just cut downbecause nicotine is a vasoconstrictor. Daily walking benefits the patient with intermittent claudication. Increased protein intake will not alleviate the patients symptoms.
Graduated compression stockings have been prescribed to treat a patients venous insufficiency. What education should the nurse prioritize when introducing this intervention to the patient?
- A. The need to take anticoagulants concurrent with using compression stockings
- B. The need to wear the stockings on a one day on, one day off schedule
- C. The importance of wearing the stockings around the clock to ensure maximum benefit
- D. The importance of ensuring the stockings are applied evenly with no pressure points
Correct Answer: D
Rationale: Any type of stocking can inadvertently become a tourniquet if applied incorrectly (i.e., rolled tightly at the top). In such instances, the stockings produce rather than prevent stasis. For ambulatory patients, graduated compression stockings are removed at night and reapplied before the legs are lowered from the bed to the floor in the morning. They are used daily, not on alternating days. Anticoagulants are not always indicated in patients who are using compression stockings.
The nurse is caring for an acutely ill patient who is on anticoagulant therapy. The patient has a comorbidity of renal insufficiency. How will this patients renal status affect heparin therapy?
- A. Heparin is contraindicated in the treatment of this patient.
- B. Heparin may be administered subcutaneously, but not IV.
- C. Lower doses of heparin are required for this patient.
- D. Coumadin will be substituted for heparin.
Correct Answer: C
Rationale: If renal insufficiency exists, lower doses of heparin are required. Coumadin cannot be safely and effectively used as a substitute and there is no contraindication for IV administration.
The nurse is providing care for a patient who has just been diagnosed with peripheral arterial occlusive disease (PAD). What assessment finding is most consistent with this diagnosis?
- A. Numbness and tingling in the distal extremities
- B. Unequal peripheral pulses between extremities
- C. Visible clubbing of the fingers and toes
- D. Reddened extremities with muscle atrophy
Correct Answer: B
Rationale: PAD assessment may manifest as unequal pulses between extremities, with the affected leg cooler and paler than the unaffected leg. Intermittent claudication is far more common than sensations of numbness and tingling. Clubbing and muscle atrophy are not associated with PAD.
A nurse has written a plan of care for a man diagnosed with peripheral arterial insufficiency. One of the nursing diagnoses in the care plan is altered peripheral tissue perfusion related to compromised circulation. What is the most appropriate intervention for this diagnosis?
- A. Elevate his legs and arms above his heart when resting.
- B. Encourage the patient to engage in a moderate amount of exercise.
- C. Encourage extended periods of sitting or standing.
- D. Discourage walking in order to limit pain.
Correct Answer: B
Rationale: The nursing diagnosis of altered peripheral tissue perfusion related to compromised circulation requires interventions that focus on improving circulation. Encouraging the patient to engage in a moderate amount of exercise serves to improve circulation. Elevating his legs and arms above his heart when resting would be passive and fails to promote circulation. Encouraging long periods of sitting or standing would further compromise circulation. The nurse should encourage, not discourage, walking to increase circulation and decrease pain.
