- Identify and interpret related laboratory tests
- Identify nursing responsibilities associated with health teaching and health promotion
The heart is the powerhouse of the body, providing oxygenated blood to organs so that they can conduct the vital processes needed to keep the body functioning. Without a properly functioning heart to ensure blood flow, cells are in jeopardy of oxygenation starvation, impairment, and subsequent death.
Did You Know?
Did you know that the average adult human heart contracts approximately 108,000 times in one day, more than 39 million times in one year, and nearly 3 billion times during a 75-year lifespan? Each heartbeat ejects approximately 70 mL blood, resulting in 5.25 liters of fluid per minute and approximately 14,000 liters per day. Over one year, that means over 2.6 million gallons of blood are sent through roughly 60,000 miles of vessels in the adult body.[1] It is no wonder that the heart is the most important muscle of the body!
In addition to the cardiovascular system, the renal system is also an important regulator of blood volume, electrolyte balance, and blood flow throughout the body. This chapter will review important concepts and disorders related to the cardiovascular and renal systems before discussing common medication classes. It is vital for nurses to understand how these cardiovascular medications work to provide safe, effective client care.
