EKG NHA CORE EXAM TEST QUESTIONS AND SOLUTIONS
RATED A+
✔✔An EKG technician should recognize that which of the following signs are often
present when a patient is experiencing ventricular tachycardia? - ✔✔Multiple premature
ventricular contraction in a row
✔✔Which of the following positions is appropriate for a patient during a nuclear stress
test while the camera is scanning? - ✔✔Supine with the arms above the head
✔✔THE TECHNICIAN SHOULD CHECK FOR THE RIGHT LEG ELECTRODE
BECAUSE ALL LEADS SHARE THIS ELECTRODE. - ✔✔
✔✔Somatic interference - ✔✔muscle movement, tensing of voluntary muscles, shifting
a body position, tremors or even talking
✔✔Which of the following leads is created between the left arm and left leg? - ✔✔Lead
III
✔✔Which of the following factors can produce an artifact that appears as uniform, small
spikes on an EKG tracing? - ✔✔Improper grounding
✔✔Bipolar leads are - ✔✔I, II, and III
✔✔Client experiencing myocardial ischemia - ✔✔will have depressed ST segment
✔✔Gain control - ✔✔adjust height of the waveform
✔✔Sinus arrest that lasts 6 seconds or longer is a medical emergency. - ✔✔
✔✔Accelerated Junctional Rhythm - ✔✔regular rhythm, rate 60-100 paper setting is
25mm/sec
✔✔ground electrode - ✔✔always RL (right leg) Does not gather information.
✔✔ventricular fibrillation - ✔✔the rapid, irregular, and useless contractions of the
ventricles
✔✔Social history - ✔✔a record of habits like smoking, drinking, drug abuse, and sexual
practices that can impact health
, ✔✔Transtelephonic monitoring - ✔✔The patient attaches a specific lead system for
transmitting the signal and places a landline telephone mouthpiece over the transmitter.
The ECG is recorded and evaluated a remote location.
✔✔ST segment elevation - ✔✔
✔✔atrial fibrillation - ✔✔rapid, random, ineffective contractions of the atrium
✔✔Silver electrodes - ✔✔to a client who is scheduled to receive a series of EKG
readings
✔✔Which of the following is a cause for discontinuing a stress test? - ✔✔ST segment
elevation
✔✔atrial depolarization - ✔✔P wave
✔✔the EKG records the - ✔✔electrical activity of the heart
✔✔Electrodes are also refered to as: - ✔✔sensors
✔✔What is the normal running speed of the EKG paper? - ✔✔25 mm/sec
✔✔The technician should recognize that leads V1 and V2 record electrical activity of the
SEPTAL WALL. - ✔✔
✔✔ST segment depression indicates - ✔✔myocardial ischemia
✔✔T wave inversion - ✔✔myocardial ischemia
✔✔sinus rhythm - ✔✔normal heart rhythm
✔✔Sinus rhythm is characterized - ✔✔upright P waves, narrow QRS complex, and
ventricular rate between 60 and 100 bpm
✔✔Right arm creates what leads? - ✔✔Lead I, II, aVR.
✔✔aVR lead - ✔✔lead AVR: points towards right arm, normally should be negative, no
electrical conductivity aiming towards right side
✔✔loss of capture (failure to depolarize) - ✔✔the pacing activity continues to occur
without evidence that the electrical activity has depolarized or captured the myocardium
