Patho Quiz 5

upon admission assessment, the nurse hears a murmur located at the 5th intercostal space, midclavicular line. The client asks, "what does that mean?" The nurse will base her answer on which of the following physiologic principles?

"You have a heart valve that is diseased"

When discussing the AV node's role in the electrical conduction of the heart with a client newly diagnosed with an AV block, which of the following statements are accurate? select all that apply

A block at the AV bundle of His interferes with normal delay of the impulse, thereby interfering with complete ejection of blood from the atria prior to ventricular contraction When there is an AV block, impulses from the atria and ventricles beat independently of each other so the heart rhythm is usually chaotic and not regular

Heart muscle differs from skeletal muscle tissue by being able to generate:

Action potentials

A client is diagnosed with an abdominal aortic aneurysm that the physician just wants to "watch" for now. When teaching the client about signs/symptoms to watch for, the nurse will base the teachings on which of the following physiological principles?

As the aneurysm grows, more tension is placed on the vessel wall which increases the risk for rupture.

Following several weeks of increasing fatigue and a subsequent diagnostic workup, a client has been diagnosed with mitral valve regurgitation. Failure of this heart valve would have which of the following consequences?

Backflow from the left ventricle to the left atrium

A client has entered hypovolemic shock after massive blood loss in a car accident. Many of the client's peripheral blood vessels have consequently collapsed. How does the Laplace law account for this pathophysiologic phenomenon?

Blood pressure is no longer able to overcome vessel wall tension

In the days following a tooth cleaning and root canal, a client has developed an infection of the thin, three-layered membrane that lines the heart and covers the valves. What is this client's most likely diagnosis?

Endocarditis

Which of the following statements about vascular compliance is accurate?

Veins can act as a reservoir for storing large quantities of blood
