NUR 514 EXAM 2 QUESTIONS AND ANSWERS GRADED A+ LATEST UPDATE.
What are the four qualities of cardiac cells? ANS >> Automaticity,
contractility, conductivity, and excitability
A heart attack is worse for the system if it occurs in what ventricle?
ANS >> Left
What system transfers the electrical beat through the heart? ANS >>
Intranodal tracts
What is the travel path of the heart beat? ANS >> SA, AV, bundle of
his, Purkinje fibbers
What beat does the SA node fire at? ANS >> 60-100
What beat does the AV node fire at? ANS >> 40-60
What do the bundle of his or Purkinje fibbers fire at? ANS >> 20-40
, NUR 514 EXAM 2
What do you want to do if cardiac muscle is damaged? ANS >>
Decrease heart work or heart rate and put on beta blockers like
metoprolol
What is the indicator of a beta blocker? ANS >> -Ollo
How do you calculate cardiac output? ANS >> HR x SV
How do blockages decrease contractility? ANS >> They kill tissue
which results in scar tissue which isn't elastic
How many bpm is sinus tach? ANS >> 100-150
How many bpm is SVT? ANS >> 150+
How man bpm is sinus? ANS >> 60-100
How many bpm is sinus brady? ANS >> 40-60
How can you tell the difference between v fib and v tach? ANS >> V fib
is everywhere, v tach is consistent
