Questions And Correct Answers
Sinus arrest may be life threatening if atrial activity is not restarted. - answer✔True
Which of the following is NOT a common cause of third-degree AV block? -
answer✔Hypertrophic obstructive cardiomyopathy
All of the following are findings of Second Degree AV Block Type I except: - answer✔Frequent
idioventricular escape beats
You recently take over care of Ms. Alrashid, a 34 year old Egyptian woman admitted to your
unit. Thirty (30) minutes ago she converts from Sinus Rhythm to atrial tachycardia. What
symptoms are she likely to report when you go in to assess her, and why? - answer✔She feels
weak and dizzy because her heart rate is so fast ventricular filling time is decreased. This is
likely to be why she is hypotensive.
A rhythm strip that has consistent R-R intervals and P-P intervals is said to be a regular rhythm. -
answer✔True
All second degree AV blocks are the result of failure of the impulse generated by the SA node to
reach the AV node. - answer✔False
Which of the following is the rate for a junctional escape rhythm? - answer✔40 - 60 beats per
minute
Multifocal atrial tachycardia, also known as Wandering Atrial Pacemaker, is identified by: -
answer✔Irregular R-R interval and P waves of different shapes
In a typical 5 lead configuration where is the white electrode (RA) placed? - answer✔The white
electrode (RA) is placed at the infraclavicular fossa, close to the right shoulder.
Atrial Fibrillation is identified by all of the following except: - answer✔B) Normal P-P interval
In a patient with a Second Degree AV block, you understand that impulses coming from the SA
node are randomly being blocked at ____________. - answer✔A point below the AV node
The PR interval: (Select all that apply) - answer✔Includes the P wave and the PR segment
Is measured from the beginning of the P wave to the beginning of the QRS
Is typically 0.12 - 0.20 seconds (120 - 200 msec)
What bipolar lead is similar to V1? - answer✔Lead MCL1
You are caring for a 16 y/o female in the emergency department. She presented with complaints
of chest pain with sudden movement or when taking a deep breath. The physician asked for her
to be placed on a cardiac monitor and to obtain a 12 Lead ECG. She is in sinus rhythm but on
closer observation you notice her HR drops from 80 to 72 during expiration, then increases to 80
again with inspiration. You identify the rhythm as _______________, and your interventions
will include _________________. - answer✔Sinus Arrhythmia; post the rhythm strip noting that
this is common in adolescents and continue to monitor
R-R interval helps determine ventricular rates. Atrial rates are determined using which of the
following? - answer✔P to P interval
Mr. Pratz is a 68 y/o male admitted to the hospital with a newly diagnosed cardiomyopathy most
likely from a viral infection. His bedside monitor shows him to be experiencing periods of
bigeminy PVCs and occasional couplets. The alarm on his monitor sounds as you enter his room.
He is awake and alert, rubbing his chest and complaining of shortness of breath and chest pain.
The physician enters the room and requests preparation for synchronized electrical cardioversion.
As you are gathering equipment to perform the cardioversion, Mr. Pratz becomes unresponsive
and has no palpable pulse. Your immediate response is: - answer✔Immediately begin CPR and
prepare to perform electrical defibrillation
To calculate the ventricular rate using the 6 second method, multiply by 10 which of the
following indicators. - answer✔Tll the R waves inside the 30 big boxes or 3 hash marks at the
top of the strip
Temporary epicardial pacing requires that: - answer✔Pacing wires are placed directly on the
heart muscle by the cardiothoracic surgeon during cardiac surgery
