Nokea
The nurse is caring for a patient with a large venous leg ulcer. What intervention should the nurse implement to promote healing and prevent infection?
- A. Provide a high-calorie, high-protein diet.
- B. Apply a clean occlusive dressing once daily and whenever soiled.
- C. Irrigate the wound with hydrogen peroxide once daily.
- D. Apply an antibiotic ointment on the surrounding skin with each dressing change.
Correct Answer: A
Rationale: Wound healing is highly dependent on adequate nutrition. The diet should be sufficiently high in calories and protein. Antibiotic ointments are not normally used on the skin surrounding a leg ulcer and occlusive dressings can exacerbate impaired blood flow. Hydrogen peroxide is not normally used because it can damage granulation tissue.

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.
A patient with advanced venous insufficiency is confined following orthopedic surgery. How can the nurse best prevent skin breakdown in the patients lower extremities?
- A. Ensure that the patients heels are protected and supported.
- B. Closely monitor the patients serum albumin and prealbumin levels.
- C. Perform gentle massage of the patients lower legs, as tolerated.
- D. Perform passive range-of-motion exercises once per shift.
Correct Answer: A
Rationale: If the patient is on bed rest, it is important to relieve pressure on the heels to prevent pressure ulcerations, since the heels are among the most vulnerable body regions. Monitoring blood work does not directly prevent skin breakdown, even though albumin is related to wound healing. Massage is not normally indicated and may exacerbate skin breakdown. Passive range-of-motion exercises do not directly reduce the risk of skin breakdown.
The triage nurse in the ED is assessing a patient who has presented with complaint of pain and swelling in her right lower leg. The patients pain became much worse last night and appeared along with fever, chills, and sweating. The patient states, I hit my leg on the car door 4 or 5 days ago and it has been sore ever since. The patient has a history of chronic venous insufficiency. What intervention should the nurse anticipate for this patient?
- A. Platelet transfusion to treat thrombocytopenia
- B. Warfarin to treat arterial insufficiency
- C. Antibiotics to treat cellulitis
- D. Heparin IV to treat VTE
Correct Answer: C
Rationale: Cellulitis is the most common infectious cause of limb swelling. The signs and symptoms include acute onset of swelling, localized redness, and pain; it is frequently associated with systemic signs of fever, chills, and sweating. The patient may be able to identify a trauma that accounts for the source of infection. Thrombocytopenia is a loss or decrease in platelets and increases a patients risk of bleeding; this problem would not cause these symptoms. Arterial insufficiency would present with ongoing pain related to activity. This patient does not have signs and symptoms of VTE.
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 nurse is taking a health history of a new patient. The patient reports experiencing pain in his left lower leg and foot when walking. This pain is relieved with rest. The nurse notes that the left lower leg is slightly edematous and is hairless. When planning this patients subsequent care, the nurse should most likely address what health problem?
- A. Coronary artery disease (CAD)
- B. Intermittent claudication
- C. Arterial embolus
- D. Raynauds disease
Correct Answer: B
Rationale: A muscular, cramp-type pain in the extremities consistently reproduced with the same degree of exercise or activity and relieved by rest is experienced by patients with peripheral arterial insufficiency. Referred to as intermittent claudication, this pain is caused by the inability of the arterial system to provide adequate blood flow to the tissues in the face of increased demands for nutrients and oxygen during exercise. The nurse would not suspect the patient has CAD, arterial embolus, or Raynauds disease; none of these health problems produce this cluster of signs and symptoms.
