Cases of cardiovascular disorders among the older adult population have been increasing constantly. The cardiovascular system weakens through time as aging cells prevail. The nurse caring for a geriatric client needs to have a broad understanding about cardiovascular diseases, their causation, diagnostic procedures, symptoms, and treatment. This text will help you become more qualified and certified to provide care for this wave of baby boomers both by better equipping you to take and pass the gerontological nursing examination or general nursing, and by expanding your knowledge about the cardiovascular system through the rationales provided in the answers for the 202 questions.

What will be the best course of action for the nurse?
