CE TEST QUESTIONS

GENERAL PURPOSE:

To provide information about the mechanism, potential complications, and nursing implications of caring for patients who are using a left ventricular assist device.

LEARNING OBJECTIVES/OUTCOMES:

After completing this continuing education activity, you should be able to:

  1. Describe the mechanism, indications, and contraindications for implantation of a left ventricular assist device.
  2. Explain the complications that can result from implantation of a left ventricular assist device.
  3. Plan the appropriate care for patients who have a left ventricular assist device.
  1. In recent years, the most common reason for implantation of a left ventricular assist device (LVAD) has become
    1. destination therapy.
    2. a bridge to cardiac transplant.
    3. a bridge to recovery in potentially reversible cardiac pathology.
  2. Compared with the first generation of LVAD devices, most LVADs implanted now
    1. are pulsatile.
    2. have a shorter lifespan.
    3. are continuous flow devices.
  3. Which of the following features of an LVAD represents the patient's cardiac output in liters per minute?
    1. the pump speed
    2. the pump flow
    3. the pulsatile index
  4. Which of the following is a function of the LVAD controller?
    1. collecting data about the system's operation
    2. pushing blood through a cannula in the aorta
    3. establishing a connection to the pump
  5. A patient who is eligible for implantation of an LVAD is expected to have
    1. an increased creatinine clearance level.
    2. a decreased blood urea nitrogen level.
    3. an increased B-type natriuretic peptide level.
  6. Which of the following disorders can make patients ineligible for implantation of an LVAD?
    1. cancer
    2. anemia
    3. diabetes mellitus
  7. Because patients with an LVAD are at risk for thrombosis, they require serial measurements of which of the following?
    1. C-reactive protein
    2. lactate dehydrogenase
    3. aspartate aminotransferase
  8. A common bacterial pathogen that can infect the percutaneous exit site of LVADs is
    1. Escherichia coli.
    2. Klebsiella pneumoniae.
    3. Pseudomonas aeruginosa.
  9. Because LVADs can cause thrombosis, patients require anticoagulation, with their international normalized ratio maintained between
    1. 0.5 and 1.5.
    2. 1.5 and 2.5.
    3. 2.5 and 3.5.
  10. A clinical manifestation of the complication of right ventricle failure following LVAD implantation is
    1. dyspnea.
    2. cool extremities.
    3. jugular vein distention.
  11. LVAD-induced ventricular dysrhythmias tend to occur as a result of
    1. hypovolemia.
    2. hypertension.
    3. preload excess.
  12. To measure blood pressure when assessing patients who have an LVAD, clinicians should use a
    1. traditional cuff and sphygmomanometer.
    2. Doppler blood pressure device.
    3. wrist blood pressure monitor.
