CVP Exam 3 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
= - CORRECT ANSWER CO ___ VR
Venous return - CORRECT ANSWER Factors that influence _____:
-body metabolism
-body size
-age
-gender
Cardiac index - CORRECT ANSWER amount of blood pumped out of heart per
minute per sq meter of body mass
Hyper - CORRECT ANSWER Causes of _________-effective heart:
-sympathetic stimulation
-hypertrophy
Hypo - CORRECT ANSWER Causes of ________-effective heart:
-hypertension
-sympathetic inhibition
-any heart pathology
High - CORRECT ANSWER In a pathologically _______ CO, the heart does not have
a problem, the peripherals do
Decreased - CORRECT ANSWER Pathologically high CO is due to _______________
peripheral resistance
,Peripheral resistance - CORRECT ANSWER Disorders that decrease
_______________ ___________(high CO)
-beriberi
-arteriovenous fistula
-hyperthyroidism
-anemia
Beriberi - CORRECT ANSWER Thymine deficiency where cells cannot use energy
well; causes decreased peripheral resistance
Arteriovenous fistula - CORRECT ANSWER abnormal connection between an artery
and a vein that can decrease peripheral resistance(high CO)
Low - CORRECT ANSWER Pathologically _______ CO can be due to cardiac or
peripheral issues
Low cardiac output - CORRECT ANSWER Cardiac causes of _______ ___________
__________:
-myocardial infarction
-severe valve disease
-myocarditis
-cardiac tamponade
Cardiac tamponade - CORRECT ANSWER acute compression of the heart caused by
fluid accumulation in the pericardial cavity; can cause low cardiac output
Low cardiac output - CORRECT ANSWER Peripheral causes of ________
___________ _________:
-low blood volume(hypovolemia)
-acute venous dilation(SNS suppression)
-large vein obstruction
, -low metabolic rate(hypothyroidism)
High, low - CORRECT ANSWER Hyperthyroidism causes _______ CO while
hypothyroidism causes ______ CO
Plateau - CORRECT ANSWER The ____________ of the venous return curve is due
to low atrial pressures leading to vein collapse
Mean systemic filling pressure - CORRECT ANSWER Place on venous return curve
that is the amount of pressure in CV system due to blood volume only
Increase, increase - CORRECT ANSWER An ______________ in blood volume and
______________ in systemic activity(vasoconstriction) can increase mean filling pressure
CO - CORRECT ANSWER Ficks principle is a measure of:
Ficks equation - CORRECT ANSWER X=Q[x]
X=delivery rate of substance X
Q=CO
[x]= substance x concentration
Stress induction - CORRECT ANSWER Does BP change more with stress induction or
whole body exercise?
Vasodilation - CORRECT ANSWER Coronary arteries contain mostly B2 adrenergic
receptors; therefore the general tendency is _______________
Parasympathetic - CORRECT ANSWER Which ANS system has very little innervation
to coronary vessels?
