PATIENT CARE DYSRHYTHMIAS STUDY GUIDE
QUESTIONS WITH 100% SOLVED ANSWERS!!
Which priority concept does the nurse focus on when a client is diagnosed with
a dysrhythmia ? Answer - Perfusion
Which normal heart rates does the nurse expect to be initiated by the primary
pacemaker of the heart ( SA Node ) in clients when the heart rate is regular ?
Select all that apply .
A. 55 beats / min
B. 62 beats / min
C. 74 beats / min
D. 86 beats / min
E. 98 beats / min
F. 110 beats / min Answer - BCDE
Which waveform does the nurse recognize as atrial depolarization when a
client is placed on a cardiac monitor ? Answer - P wave
How would the nurse best interpret the electro- cardiogram ( ECG ) of a
younger athletic client which shows sinus bradycardia with a rate of 54 beats /
min ? Answer - The sinus bradycardia provides an adequate stroke volume that
is associated with cardiac conditioning
, To determine if a client has a pulse deficit , what procedure would the nurse
follow ? Answer - Assess the apical and radial pulses for a full minute and
calculate the difference
Which ECG waveforms and intervals are the normal measurements or positions
? Select all that apply .
A. PR interval 0.12-0.20 second
B. QRS complex 0.06-0.10 second
C. PR segment isoelectric line
D. QT interval less than half of the R to R interval
E. U wave follows T wave if present
F. TP segment one block above isoelectric line Answer - ABCDE
Which definition best describes the electro- physiologic property called
automaticity of myocardial pacemaker cells ? Answer - The ability of cardiac
cells to generate an electrical impulse spontaneously and repetitively
Caffeine To best perform a 12 - lead ECG on a client , how does the nurse place
the leads on the client ? Answer - Four leads are placed on the limbs and six
are placed on the chest
Where will the nurse place the leads on a client for a five - lead continuous
monitoring system ? Select all that apply.
A. Right arm electrode just below the right clavicle
B. Left arm electrode just below the left clavicle
C. Right leg electrode on the highest palpable rib , on the right midclavicular
line
D. Left leg electrode on the lowest palpable rib , on the left midclavicular line.
E. Fifth electrode placed to obtain one of the six chest leads
