1) The Inherent Rate Of The Sa Node Is ____ Bpm.
A) 30-60
B) 40-60
C) 60-100
D) 100-120
ANSWER: C
Learning Obj.: 1.3
Rationale: The Sinoatrial (Sa) Node, Often Referred To As The Heart's Natural
Pacemaker, Has An Inherent Rate Of 60-100 Beats Per Minute (Bpm). It Is Responsible
For Initiating The Electrical Impulses That Regulate The Heart's Rhythm. When
Functioning Normally, The Sa Node Sets The Pace For The Rest Of The Conduction
System.
2) The Inherent Rate Of The Av Junction Is ____ Bpm.
A) 20-40
B) 40-60
C) 60-100
D) 100-120
,ANSWER: B
Learning Obj.: 1.3
Rationale: The Av Junction, Which Includes The Av Node And Surrounding Tissue, Has
An Inherent Rate Of 40-60 Bpm. This Area Serves As A Secondary Pacemaker When
The Sa Node Fails To Generate Impulses. Although The Rate Is Slower Than That Of
The Sa Node, It Can Take Over The Pacing Role If Necessary.
3) The Inherent Rate Of The Ventricle Is ____ Bpm.
A) 20-40
B) 40-60
C) 60-100
D) 100-120
ANSWER: A
Learning Obj.: 1.3
Rationale: The Ventricles Have The Slowest Inherent Rate Of 20-40 Bpm. When Higher
Pacemaker Sites (Such As The Sa Node Or Av Junction) Fail, The Ventricles Can
Generate Electrical Impulses To Maintain A Basic Heart Rate, Although The Rate Is
Much Slower Than Normal.
4) The Built-In Rate Of Each Of The Three Major Areas Of The Conduction System Is
Referred To As The ____ Rate.
A) Fast
,B) Heart
C) Escape
D) Inherent
ANSWER: D
Learning Obj.: 1.3
Rationale: The Term "Inherent Rate" Refers To The Natural Pacemaker Activity Of The
Three Major Areas Of The Conduction System (Sa Node, Av Junction, And Ventricles).
Each Of These Areas Has Its Own Built-In Rate At Which It Generates Electrical
Impulses, Determining The Heart Rate When They Assume Pacing Control.
5) What Term Is Used To Refer To The Process Of Electrical Discharge And The Flow
Of Electrical Activity?
A) Repolarization
B) Depolarization
C) Polarization
D) Polarized
ANSWER: B
Learning Obj.: 1.2
Rationale: Depolarization Refers To The Process In Which Cardiac Cells Undergo
Electrical Discharge, Leading To The Transmission Of Electrical Impulses That Trigger
, The Heart To Contract. This Is The Process Responsible For The Heart's Rhythmic
Beating.
6) If Polarizing Is Considered The Ready State, Then ____ Would Be Considered The
Recovery State.
A) Discharge
B) Polarization
C) Repolarization
D) Depolarization
ANSWER: C
Learning Obj.: 1.2
Rationale: Repolarization Is The Recovery Phase During Which Cardiac Cells Return
To Their Resting Electrical State After Depolarization. Polarization Is The State Of
Readiness Before Depolarization Occurs, And Repolarization Restores The Cells To A
Resting State, Preparing Them For The Next Cycle.
7) After Leaving The Area Of The Av Node, Impulses Go Through The ____ To Reach
The Right And Left Bundle Branches.
A) Purkinje Fibers
B) Bundle Of His
C) Av Junction
D) Sa Node
