Exam 3- NURS 5315: Concept and Clinical Conditions(Part I Cardiovascular System) Qs & As
How does blood flow through the chambers of the heart? Correct-a) RA
b) Trucuspid
c) RV
d) Pulmonary arteries (semilunar)
e) Pulmonary veins
f) LA
g) Mitral
h) LV
i) Aorta (semilunar)
Full contraction and relaxation is one ____. Correct-Cardiac Cycle
During diastole what part of the heart fills with blood? Correct-Ventricles
What occurs during systole? Correct-Ventricular contraction pushes the blood from he
right ventricle to the pulmonary artery and from the left ventricle into the aorta
, Exam 3- NURS 5315: Concept and Clinical Conditions
(Part I Cardiovascular System) Qs & As
During atrial kick the pressure from the left atrial contraction make it possible for what part of
the body to fill with blood? Correct-Left ventricle
Which side of the heart has higher pressures and which side of the heart has lower pressures?
Correct-Right side has lower pressures
Left side has higher pressures (pumps oxygenated blood to the rest of the body)
Right ventricle systolic pressure is the pressure at the peak of systole, what is the numeric
range? Correct-15-28mmHg (pushing blood to through pulmonary trunk and artery)
Right ventricle end diastolic pressure is the pressure at the end of the diastole, right before
systole, what is the numeric range of pressure? Correct-0-8mmHg (low because ventricles
fill with blood and are relaxing)
Left ventricle systolic pressure is the pressure at the peak of systole, what is the numeric
range of this pressure? Correct-90-140 mmHg (High because it's pushing blood through the
aorta to the rest of the body)
, Exam 3- NURS 5315: Concept and Clinical Conditions
(Part I Cardiovascular System) Qs & As
Left ventricular end diastolic pressure us the pressure at the end of diastole, right before
systole, what is the numeric range of this pressure? Correct-4-12mmHg (Low because left
ventricles are relaxing filling with blood from the left atria)
What is the name of the amount of blood pushed from the left ventricle in 1 minute?
Correct-Cardiac Output
What is considered normal cardiac output? Correct-5L/min
A decrease in heart rate and a decrease is stroke volume will have what effect on Cardiac
Output (CO)? Correct-Decreased cardiac output
The amount of blood ejected by the ventricle to the body for each cardiac cycle (heart beat) is
called? Correct-Stroke volume
, Exam 3- NURS 5315: Concept and Clinical Conditions
(Part I Cardiovascular System) Qs & As
An oxygen saturation of <____% results in a decreased myocardial contraction. Correct-
50%
The percentage of blood which is ejected from the ventricle is called? Correct-Ejection
Fraction
What is the range for a normal Ejection Fraction? Correct-55-65%
Define Preload Correct-The stretch of the myocardium or end diastolic volume of the
ventricles and most frequently refers to the volume in a ventricle just before the start of
systole (at max stretch)
Increased preload can lead to what clinical condition? Correct-Heart failure
What is another term for Systemic Vascular Resistance (SVR)? Correct-Afterload
