What % Of The Cardiac Cycle Is Provided By The Atrial Kick?
• 15% • 20%
• 30%
• 35% - Correct Answer>>20%
Atrial Kick Is A Term That Represents The Amount Of The Total Co That Is
Supplied Via Atrial Contraction.
If The Pt Has A Condition Or Dysrhythmia That Impairs Or Eliminates The Atrial
Contraction, The Pt May Be Compromised.

Atrial Kick - Correct Answer>>Atrial Kick Is A Term That Represents The
Amount Of The Total Co That Is Supplied Via Atrial Contraction.
A Normal Value For An Ef Would Be?
• 65% • 40%
• 30%
• 25% - Correct Answer>>65%
The Ef Should Be More Than 50%. It Represents The Amount Of Blood Ejected
From The Left Ventricle Compared To The Total Amount Available, Expressed As
A %. An Ef Of 35% Or Less Indicates A Problem With Contractility, Outflow Or
Filling.
Exa: If The Ventricle Contains 90ml Of Blood And 50mls Are Ejected, The
Amount Would Be Expressed As A %, In This Case 55%.
A 67 Year Old Male Is Admitted With Chest Pain After Collapsing At Home. He
Is Arguing With His Wife That He Should Not Be Admitted Because He "Just
Over Did It" While Working In The World. Lee's Wife States To You That His
Chest Pain Is More Frequent, Severe And Prolonged Than Before. You Should
Anticipate What Diagnosis? • Exertional Angina
• Unstable Angina
• Variant Angina
• Stable Angina - Correct Answer>>Unstable Angina
pg. 2
, 3
The Change In Quality, Frequency, And Duration Indicates Unstable Angina And
May Indicate That The Pt Is At Increased Risk For An Mi. This Pt Should Be
Closely Monitored For Ekg Changes And Rhythm Disturbances. Pt/ Family
Teaching Should Begin On How To Identify An Mi And Basic Cpr.
Stroke Volume Is Comprised Of Which Of The Following Factors?
• Blood Volume, Viscosity, Impedance
• Cardiac Output, Hr, Compliance
• Contractility, Preload, Afterload
• Compliance, Impedance, Hr - Correct Answer>>Contractility, Preload And
Afterload
A Reflex Tachycardia Caused By The Stretch Of The Right Atrial Receptors Is
Known As The ____
• Herring-Sines Law
• Renin-Angiotensin System
• Starling's Law
• Bainbridge Reflex - Correct Answer>>Bainbridge Reflex
It Is Believed That This Reflex Exists To Speed Up The Hr If The Right Side
Becomes Overloaded, Thereby Helping Equalize Pressures On Both Sides
Diastole Comprises What & Of The Cardiac Cycle?
•½
• 2/3
•¼
pg. 3
, 4
• 1/3 - Correct Answer>>2/3
Some People That The Heart Is Virtually Static During Diastole.
During This Period, The Cardiac Vessels And Chambers Fill—A Process That
Takes Up 2/3s Of The Time Necessary To Complete The Cardiac Cycle
What Is The Map (Mean Arterial Pressure) For Pt:
Bp 120/70
Hr 80 - Correct Answer>>Map=2(Dbp) + (Sbp)/3
Map=2(70) + 120/3
Map=260/3
Map=86.6
Pts Should Maintain A Map Of At Least 60 To Ensure Adequate Perfusion To The
Brain And Kidneys.
