Chronic venous insufficiency: A review for nurses

PURPOSE: To provide information for nurses to help patients manage CVI. LEARNING OBJECTIVES/OUTCOMES: After completing this continuing-education activity, you should be able to: 1. Describe the pathophysiology of CVI. 2. Outline diagnostic studies for patients with CVI. 3. Identify nursing interventions for patients with CVI.

  1. The prevalence of CVI is difficult to estimate due to
    1. difficulty differentiating it from PAD.
    2. inconsistent standards of evaluation.
    3. the low incidence of venous ulcers needed to confirm diagnosis.
  2. Veins can accommodate large amounts of blood due to
    1. high pressures in the venous system.
    2. the muscular nature of veins.
    3. action of the venous pump.
  3. Which disorder increases the risk of CVI?
    1. heart failure
    2. diabetes mellitus
    3. DVT
  4. Patients with advanced CVI are at risk for ulceration if
    1. decreased circulation results in unmet metabolic demands.
    2. poor nutrition inhibits cellular uptake.
    3. venous congestion results in edema.
  5. Compromised inflammatory and immune responses to venous stasis ulcers put the patient at risk for
    1. peripheral neuropathy.
    2. arterial stenoses.
    3. infection.
  6. Patient risk factors for CVI include
    1. male gender.
    2. family history of PAD.
    3. pregnancy.
  7. Early signs and symptoms of CVI often include
    1. aching pain.
    2. skin discoloration.
    3. numbness.
  8. Edema associated with CVI
    1. often starts with bilateral ankle swelling.
    2. often subsides with leg elevation.
    3. is best controlled by regular use of antiembolism stockings.
  9. Hyperpigmentation of the skin is associated with
    1. hemosiderin deposits.
    2. dilated reticular veins.
    3. stasis dermatitis.
  10. Which of the following describes venous ulcers?
    1. full-thickness wounds with regular edges
    2. shallow wounds with irregular edges
    3. shallow wounds with undermining
  11. Which assessment finding can help rule out PAD in patients with suspected CVI?
    1. hyperpigmentation on lower leg
    2. palpable dorsalis pedis pulses
    3. pitting edema in lower extremities
  12. Which of the following helps differentiate DVT from CVI?
    1. ABI
    2. arteriography
    3. duplex ultrasonography
  13. All of the following help oppose venous hypertension in the lower extremities except
    1. compression therapy.
    2. diuretics.
    3. exercise.
  14. Which option is best to manage lower extremity edema in a patient with limited mobility?
    1. compression stockings
    2. continuous ankle compression
    3. intermittent pneumatic compression
  15. Instruct patients to apply compression stockings
    1. at bedtime.
    2. first thing in the morning.
    3. as needed when edema increases.
  16. Teach patients with CVI to
    1. minimize physical activity if possible.
    2. stand when applying compression stockings.
    3. inspect their skin daily for injuries.
  17. To manage lower extremity edema, recommend leg elevation for
    1. 30 minutes three to four times a day.
    2. 30 minutes twice a day.
    3. 60 minutes twice a day.
  18. A good skin care regimen helps
    1. protect fragile skin from injury.
    2. prevent hemosiderosis.
    3. manage edema.
