DYSRHYTHMIAS CERTIFICATION
EVALUATION EXAM SCRIPT COMPLETE
QUESTIONS AND ANSWERS
●● the primary pacemaker of the heart, the SA node, is functional if a
patient's pulse is what regular rate
Answer: 60-100 beats/min
●● the nurse is taking vital signs and reviewing the ECG of a patient
who is training for a marathon. the HR is 45BPM and the ECG shows
sinus bradycardia. how does the nurse interpret this data
Answer: an adequate stroke volume that is associated with cardiac
conditioning
●● the nurse is performing an assessment on a cardiac patient. in order
to determine if the patient has a pulse deficit, what does the nurse do
Answer: asses the apical and radial pulses for a full minute and calculate
differences in rate
●● what does the P wave in an ECG represent?
Answer: atrial depolarization
●● what is the normal measurement of the PR interval in an ECG
,Answer: 0.12-0.20 second
●● what is the normal measurement of QRS complex in an ECG
normally
Answer: less than 0.12 second
●● what is the normal position of the ST segment in an ECG
Answer: isoelectric
●● what is the total time required for ventricular depolarization and
repolarization as represented on the ECG?
Answer: QT interval
●● the nurse is performing a 12-lead ECG on a patient with chest pain.
because the positioning of the electrodes is crucial, how does the nurse
place them?
Answer: four leads are placed on the limbs and six are placed on the
chest
●● because cardiac dysrhythmias are abnormal rhythms of the heart's
electrical system, the heart is unable to perform what function
Answer: it cannot effectively pump oxygenated blood throughout the
body
, ●● the nurse is caring for several patients in the telemetry unit who are
being remotely watched by a monitor technician. what is the nurse's
primary responsibility in the monitoring process of these patients
Answer: assessment and management of patients
●● a patient in the telemetry unit who has continuous ECG monitoring
is scheduled for a test in the radiology department. who is responsible
for determining when monitoring can be suspended
Answer: HCP
●● the nurse is reviewing preliminary electrocardiogram results of a
patient admitted for mental status changes. the nurse alerts the HCP
about ST elevation or depression in the patient because it is an indication
of which condition
Answer: myocardial injury or ischemia
●● the nurse is reviewing ECG results of a patient admitted for fluid and
electrolyte imbalances. the T waves are tall and peaked. the nurse reports
this finding to the health care provider and obtains an order for which
serum level test
Answer: potassium
●● which actions are the responsibilities of the monitor technician
Answer: -watch the bank of monitors on a unit
-print routine ECG strips
