1

Tall slender P-wave = ___ atrial enlargement

Right

2

Wide P-wave = _____ atrial enlargement

Left

3

What determines stroke volume?

Preload, afterload, contractility rate

4

What determines cardiac output?

Stroke volume x HR

5

What is the heart's response to acute blood loss?

Incr CO via catecholamine-induced vasoconstriction

6

How does the kidney respond to acute blood loss?

ADH release causes H2O and Na resorption

7

How does the spleen respond to acute blood loss?

Contraction injects RBCs into circulation

8

What is the ECF:ICF ratio?

1:2

9

What % of body weight is comprised of water?

TBW = 60% BW

10

What is the ECF made of?

Plasma, interstital fluid, lymph

11

Critical reduction in intravascular volume (dehydration, hemorrhage, third-spacing)

Hypovolemic shock

12

How does hypovolemia cause shock?

Decr preload = decr SV = decr CO

13

Result of decreased myocardial contractility with subsequent decrease in O2 delivery

Cardiogenic shock

14

What type of shock is always assoc. w/primary heart disease?

Cardiogenic shock

15

Occurs w/abnormal blood distribution that impairs blood return to the heart

Obstructive shock

16

Type of shock that is typically secondary to sepsis and anaphylactic reaction causing vasodilation

Distributive/vasogenic shock

17

Sound made by the closure of the AV valves

S1

18

Sound made by the closure of the pulmonic and aortic valves

S2

19

Subtle sound caused by ventricular relaxation (not usually heard in small animals)

S3

20

Subtle sound assoc. w/atrial contraction (not heard in small animals)

S4

21

Which ICS do you listen to the pulmonic valve?

L 3rd

22

Which ICS do you listen to the aortic valve?

L 4th

23

Which ICS do you listen to the mitral valve?

L 5th

24

Which ICS do you listen to the tricuspid valve?

R 3-4th

25

Small slit that allows shunting between RA and LA in fetus but disappears when lungs expand with first breath

Foramen ovale

26

Which direction is the shunt if the foramen ovale fails to close?

LA to RA

27

Calf with failure to thrive, pulmonary edema, and pneumonia likely has which congenital heart defect?

VSD

28

Which direction is blood shunted with VSD?

L to R

29

What does a R to L shunt cause?

Polycythemia

30

What heart condition causes a polycythemia?

Tetralogy of Fallot
