Q

A patient has a left ventricular assist device (LVAD). what would they have previously experienced

17
Q

what should you expect from a patient with a LVAD and continuous flow

A

absence of palpable pulse

18
Q

What does a PTCA do

A

dilate the affected coronary artery w/ small balloon

19
Q

AMI occurs when

A

myocardial tissue dies secondary to absence of O2

20
Q

why is cardiac output decreased if the heart goes too rapidly

A

no enough time for heart to refill

21
Q

in contrast to an AICD, an external defibrillator vest,

A

delivers high-energy shocks similar to an AED

22
Q

Ischemic heart disease is defined as

A

decreased blood flow to one or more portions of myocardium

23
Q

why is transport of a patient w/ suspected AMI important

A

may be eligible for thrombolytic therapy

24
Q

sudden death following AMI is most often caused by

A

ventricular fibrillation

25
the descending aorta divides into the two illiac arteries at the level of the
umbilicus
26

31
which of the following is the most reliable method of estimating a patients cardiac output
assess the heart rate and strength of the pulse
32
which gives the greatest inc in cardiac output
inc heart rate, inc stroke volume
33
