PCT NHA Module 5 Exam Questions
and Answers5
In which of the following locations should a patient care technician place the V5 lead ? -
ANSWERS-At the anterior axillary line on the same horizontal level as V4
This is the lead placement for V5 .
A patient care technician is monitoring a patient who goes into asystole . Which of the following
actions should the technician take first ? - ANSWERS-Initiate CPR .
If a patient is unresponsive , the first action the technician should take is to initiate CPR . The
technician should identify that , if a patient is in asystole , no rhythm or electrical current is
traveling though the patient's cardiac conduction system on a sustained basis . It appears as a
flat line on the EKG .
A patient care technician is preparing to perform a 12 - lead EKG for a patient who has a heart
rate of 225 / min . Which of the following paper - speed settings should the technician expect
the provider to prescribe ? - ANSWERS-50 mm / sec
The technician should expect the provider to prescribe the paper speed to be increased to 50
mm / sec to make the tracing easier to read for a patient who has a fast heart rate .
A patient care technician is performing a right - sided 12 - lead EKG . For which of the following
conditions will a provider request a right - sided EKG ? - ANSWERS-Dextrocardia
The technician should identify that dextrocardia requires a right - sided EKG . With this
anatomical variation , the heart is on the right , rather than the left , side of the chest
, A patient care technician is performing a 12 - lead EKG for a patient . The technician should use
which of the following as a reference to compare the cardiac complexes during a cardiac cycle
on an EKG tracing ? - ANSWERS-Calibration marks
The technician should recognize that calibration marks indicate standardization on the machine
for recording and a reference to compare with the cardiac complexes during a cardiac cycle on
an EKG tracing . Calibration marks are small , rectangular waveforms that typically appear at the
beginning of each lead and indicate the standard paper speed and amplitude of the EKG .
A patient care technician should identify that which of the following parts of the EKG machine
regulates the height of the waveforms on the tracing ? - ANSWERS-Gain control
The technician should identify that the gain control regulates the height of the EKG waveforms
on the tracing .
A patient care technician is caring for a patient who is experiencing cardiopulmonary
compromise . The technician should identify that which of the following structures of the
cardiac conduction system initiates the heartbeat ? - ANSWERS-Sinoatrial node ( SA node )
The SA node is the pacemaker of the heart and initiates the heartbeat .
A patient care technician is performing a 12 - lead EKG . Which of the following should the
technician identify as a dysrhythmia ? - ANSWERS-Three different P wave configurations in one
lead .
The technician should identify that three different P wave configurations in one lead can
indicate a wandering atrial pacemaker . This is a result of the site of the pacemaker shifting
between the SA node and other sites in or around the atria or the AV junction
