Femoral artery

Question 2

Volume and pressure inside the left ventricle at the end of diastole is referred to as:

Answer 2

preload

Question 3

Volume and pressure inside the left ventricle at the end of diastole is referred to as:

Answer 3

afterload

Question 4

Coronary arteries receive the majority of arterial blood supply during:

Answer 4

Diastole

Question 5

The primary effects of intra-aortic balloon counterpulsation are:

Answer 5

increased myocardial O2 supply/decreased myocardial O2 demand

Question 6

Intra-aortic balloons are indicated for:

Answer 6

ACS, cardiac and non-cardiac sx, complications of HF

Question 7

Diastolic augmentation can be affected by:

Answer 7

1. The pt (hemodynamics)
2. The Catheter (position)
3. the pump (timing)

Question 7

Diastolic augmentation can be affected by:

Answer 7

1. The pt (hemodynamics)
2. The Catheter (position)
3. the pump (timing)

Question 8

Restriction of gas flow through the IAB may be caused by:

Answer 8

Kink in the catheter

Question 9

SV may be decreaesd by:

Answer 9

tachycardia, decreased cardiac index, dysrhythmias

Question 10

Two AV valves are:

Answer 10

mitral and tricuspid

Question 11

two semilunar valves are:

Answer 11

aortic and pulmonic

Question 12

the dicrotic notch signifies

Answer 12

the beginning of diastole

Question 13

The intra-aortic balloon will be timed to inflate:

Answer 13

At the dicrotic notch (at the beginning of diastole)

Question 14

The intra-aortic balloon will be timed to deflate:

Answer 14

Before the aortiv valve opens (just prior to systole))

Question 15

Inflation of the IAB will result in:

Answer 15

augmentation of DBP and increased coronary perfusion

Question 16

Deflation of the IAB will result in:

Answer 16

Decreased afterload and decrased myocardial O2 demand

Question 17

Proper placement of the intra-aortic balloon catheter in a femoral artery insertion is with the tip of the catheter:

Answer 17

Just distal to the left subclavian artery

Question 18

T/F: balloon placement does not affect diastolic augmentation

Answer 18

false

Question 19

T/F: An intra-aortic balloon membrane could be abraded by calcific plaque, leading to a membrane leak.

Answer 19

true

Question 20

Label A-F

Answer 20

A= unassisted systole
B= diastolic augmentation
C= assisted systole
D= unassisted end diastolic pressure
E= balloon inflation
F= assisted end-diastolic pressure
