NURS 1871 UNIT 3 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
Ameliorable adverse event
events that, while not preventable, could have been less harmful if care had been
different
Perfusion
the flow of blood through arteries and capillaries delivering nutrients and oxygen to
cells.
Central perfusion is generated by
cardiac output
Cardiac output
the amount of blood pumped by the heart each minute; electrical and mechanical
factors that move blood through the heart into the peripheral vessels.
S1
Lub; closes the mitral and tricuspid valves
S2
Dub; aortic and pulmonic valves to close
Arteries/Artioles maintain B/P by
constricting or dilating in response to stimuli
Venules
branches of the veins that help return blood to the heart
, Ischemia
a reversable cellular injury that occurs when the demand for oxygen exceeds the supply
because of a reduction in blood flow; if prolonged, can become irreversible.
Perfusion impaired by immobility can cause two problems:
pressure injuries and venous thrombi
Stasis
slowing or stopping of the normal flow of a fluid, such as blood
thrombus
blood clot
syncope
fainting or sudden loss of consciousness caused by lack of blood supply (cerebral
perfusion); fainting
Eccymosis
Bruise; Bleeding visible beneath the skin as a blue or purple patch.
systole lift
slight thrust heard during palpation
systole heave
a prominent thrust heard during palpation
pitting edema
edema that retains an imprint when touched
poikilothermia
Cool skin temp due to impaired arterial perfusion
Amplitude
