NUR 211 EXAM #3 – HEMODYNAMICS
QUESTIONS AND CORRECT
ANSWERS
systole = ventricular ________ ANSW✅✅contraction (semilunar valves open)



diastole = ventricular _____________ ANSW✅✅relaxation (AV valves open)



what 3 components make blood pressure? ANSW✅✅1. Pressure (pump)

2. Flow (volume)

3. Resistance (clamp)



CVP: ANSW✅✅2-6



volume component



PAP: ANSW✅✅25/10



volume component



PAWP: ANSW✅✅6-12



volume component



CO: ANSW✅✅4-8



pump component



CI: ANSW✅✅2.5.-4

, pump component



SVR: ANSW✅✅700-1400



clamp component



if SVR is decreased = vasodilation

if SVR is increased = vasoconstriction



Nitro will (increase/decrease) SVR? ANSW✅✅decrease.



Nitroglycerin is a vasodilator.



ABP = SVR x ? ANSW✅✅CO.



ABP = clamp x pump



CO = HR x ? ANSW✅✅SV (stroke volume)



how hard you can pump = HR x SV (fluid)



SV = ? ANSW✅✅the amount of *fluid* pumped out with each beat of the heart.



it is affected by preload, afterload, and contractility.



ventricular repolarization = ? ANSW✅✅diastole

what is the normal blood flow through the heart? ANSW✅✅inferior/superior vena cavas, right
atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary vein,
left atrium, bicuspid (mitral) valve, left ventricle, aortic valve, aorta, body



capillaries allow for? ANSW✅✅gas exchange
