ECG exam
To determine the quality of atrial activity on an ECG strip, the ECG technician should examine which of
the following portions of the cardiac cycle?
QT interval
PR interval
ST segment
T wave - Answer-PR interval
- Answer-
, A patient arrives late after witnessing an auto accident. In preparation for running the patient's ECG, the
technician notes an increased anxiety level. Which of the following should the technician do? (Select the
three (3) correct answers.)
speak clearly and softly to patient.
allow time for the patient to relax.
obtain vital signs promptly.
document the patient's state in the report.
run two ECGs ten minutes apart. - Answer-speak clearly and softly to patient., allow time for the patient
to relax., document the patient's state in the report.
An ECG technician performs an ECG on a patient and upon completion the standardization mark appears
as shown above. The technician should recognize that the test was with the machine set to which of the
following settings? *looks like a square on the ekg strip* - Answer-20 mm/mV and 25 mm/sec.
Proper electrode placement for continuous ECG monitoring is identified by the use of
3 leads placed on the patient's torso.
5 electrodes placed on the patient's extremities and torso.
10 electrodes placed on the patient's torso.
12 electrodes placed on the patient's extremities and torso. - Answer-3 leads placed on the patient's
torso.
The time from ventricular depolarization through repolarization is represented by the
QRS complex.
PR interval.
QT interval.
PR segment. - Answer-QT interval.
