Cardiac-Vascular Nursing (CVRN) Practice Exam

What is the optimal outcome of using left ventricular assist devices (LVADs) for heart failure patients?

1. Improved quality of life and increased life span

2. Eventual non-assisted improvement in left ventricular dysfunction

3. Improved respiratory function until death occurs

4. Remodeling the left ventricles for improved cardiac output

The correct answer is: Improved quality of life and increased life span

The optimal outcome of using left ventricular assist devices (LVADs) for heart failure patients is improved quality of life and increased life span. LVADs are designed to support the failing heart by helping it pump blood effectively throughout the body. This mechanical support can significantly relieve symptoms of heart failure, such as fatigue, shortness of breath, and exercise intolerance, which in turn enhances the patient’s overall quality of life. Furthermore, LVADs can extend life expectancy for many patients with advanced heart failure, especially for those who may not be candidates for heart transplant. By enabling better hemodynamics and organ perfusion, LVADs allow patients to live longer while managing their heart failure symptoms more effectively. While the other options may reflect certain aspects of heart failure management, they do not capture the primary intention and benefit of LVAD therapy. For instance, non-assisted improvement is not typically expected for those in advanced heart failure; respiratory function is not the main focus of LVAD treatment; and although some ventricular remodeling can occur with improved hemodynamics, this is not the primary goal. Hence, the most significant and recognizable outcomes of LVAD use remain the enhancement of life quality and longevity for heart failure patients.
