NR 507 Advanced Pathophysiology Midterm Exam<\/p>\n\n\n\n

How does blood flow through the heart?
Correct Answer:
Deoxygenated venous blood \u2192 Sup. Vena Cava \u2192 Right Atrium \u2192Tricuspid
(AV) \u2192Empties into R. Ventricle (& it contracts) \u2192 Blood ejected through
Pulmonary Valve \u2192 Pulmonary Artery \u2192 Lungs to be Oxygenated \u2192
Pulmonary Veins \u2192 L. Atrium \u2192 Mitral (AV) \u2192 L. Ventricle (pumps with each
contraction) \u2192 Aortic Valve \u2192 Aorta \u2192 Body
What is systole?
Correct Answer:
Contraction of the heart which pumps blood
Diastole
Correct Answer:
Relaxation of the heart
What produces S1 and S2 sound?
Correct Answer:
closing of the heart valves<\/p>\n\n\n\n

NR 507 Advanced Pathophysiology Midterm Exam<\/p>\n\n\n\n

What produces S1?
Correct Answer:
The mitral and tricuspid valves which close in systole
What produces S2 sound?
Correct Answer:
The closing of the aortic and pulmonic valves in diastole
What is cardiac output?
Correct Answer:
the volume of blood pumped out by each ventricle per minute
What is stroke volume?
Correct Answer:
amount of blood pumped out by each ventricle with contraction
What determines cardiac output?
Correct Answer:
stroke volume and heart rate<\/p>\n\n\n\n

What is preload?
Correct Answer:
the degree of stretch on the heart before it contracts, related to ventricular
filling, end diastolic pressure, amount of blood entering the ventricle during
diastole
What is afterload?
Correct Answer:
resistance left ventricle must overcome to circulate blood<\/p>\n\n\n\n

What is contractility?
Correct Answer:
Normal ability of muscle to contract at a given force for a given stretch. It is
independent of preload\/afterload
Will sustained tachycardia result in increased or decreased stroke volume?
Correct Answer:
Decreased
What conditions can result in decreased contractility?
Correct Answer:
Ischemia, acidosis, cardiomyopathy<\/p>\n\n\n\n
