1
Which of the follow statements is true about events that occur during a normal cardiac cycle?
An increase in cardiac output increases diastole
Metabolism in the heart is decreased during diastole
Diastole comprises about 40% of the cardiac cycle
Metabolism in the heart is unchanged during diastole
2
Which of the following hemodynamic changes occur with cardiac tamponade?
Increased cardiac output
Decreased heart rate
Increased contractility
Decreased Stroke volume
3
Blood gas sample results: RA = Sat 75%, RV = 92% & PA = 92%. These results indicate:
Coarctation of the aorta
Pericarditis
Catheter malfunction
VSD
4
Which of the following are the symptoms of Beck's triad (used to diagnose cardiac tamponade)?
LV failure, tachycardia, hypertension
Distended neck veins, muffled heart sounds, hypotension
Pericardial friction rub, hypertension, RV failure
Increased pulse pressure, Increased JVD, tachycardia
5
The moderate sized VSD results in:
Left to right shunt
Right to left shunt
Decreased systemic vascular resistance
Decreased pulmonary vascular edema
6
A pt with tricupsid atresia may exhibit:
Small, inverted P waves
Smaller than normal heart
Sinus tachycardia
Polycythemia
7
You hear a S3 heart sound on your pt. This sound occurs as a result of:
Closure of the aortic & pulmonic valves
Active atrial contraction
Increaed blood flow across the AV values
Aortic stenosis

VVT
11
The LA line in your pt is reading 18 mmHg. This value may indicate:
Tricuspid regurgitation
Mitral value dysfunction
Pulmonary embolus
Pulmonic stenosis
12
The reflex tachycardia caused by stretch of right atrial receptors is known as:
The Bainbridge Reflex
The renin-angiotensin system
Starling's Law
The Herring-Sines law
13
The ejection fraction most closely represents which of the following hemodynamic parameters?
RVP
LVEDP
RVEDP
PAOP
14
An example of pansystolic murmur is:

Atrial stenosis
15
Which of the following statements is true regarding the Glenn procedure (stage 2 HLHS)?
The ductus is left open until the 3rd stage is complete
The ductus is ligated & the PA is divided
Single right vent supplies systemic circulation after done
The superior vena cava is anastomosed to the right PA
