1.
A certified EKG technician is preparing to obtain a standard 12-lead
electrocardiogram on an adult patient who has been resting quietly in the
examination room. Before placing the electrodes, the technician explains
the procedure, confirms the patient's identity, provides appropriate
privacy, and positions the patient correctly. Which position should the
technician use to obtain the most appropriate standard resting 12-lead
ECG tracing?
A. Sitting upright with both arms crossed over the chest
B. Supine with the arms relaxed at the sides and legs uncrossed
C. Prone with the head turned to one side and arms extended
D. Standing with the feet together and hands resting on the hips
Answer: B
2.
A patient arrives in the cardiology department for a routine resting
12lead ECG and reports that they are nervous because they have never
had an electrocardiogram performed before. The patient asks whether
the electrodes will cause an electrical shock during the procedure. Which
response by the EKG technician is most appropriate when explaining the
basic purpose and safety of the ECG?
A. The electrodes deliver a small electrical current into the heart to
measure cardiac function
,2
B. The electrodes continuously stimulate the heart while the machine
records the resulting rhythm
C. The electrodes detect and record the heart's electrical activity
without delivering electricity into the body
D. The electrodes temporarily stop the heart so that the machine can
measure ventricular activity
Answer: C
3.
An EKG technician is preparing a patient for a standard 12-lead ECG
and notices that the patient's skin is visibly sweaty and contains a
significant amount of perspiration. The technician understands that
excessive moisture can interfere with electrode adhesion and may
introduce artifact into the tracing. What should the technician do before
applying the electrodes?
A. Apply the electrodes directly over the perspiration
B. Dry the skin thoroughly before applying the electrodes
C. Place additional electrodes over the same locations
D. Apply petroleum jelly to improve electrical conduction Answer: B
4.
While preparing to obtain a 12-lead ECG, an EKG technician observes
that the patient has a substantial amount of chest hair at several electrode
placement sites. The technician needs to ensure that the electrodes
maintain adequate contact with the skin and that the resulting tracing is
not compromised by poor adhesion. Which action is most appropriate?
A. Place the electrodes on top of the hair without making any
,3
adjustments
B. Apply lotion to the hair before placing the electrodes
C. Remove a small amount of hair from the necessary electrode sites if
needed
D. Replace all disposable electrodes with limb electrodes only Answer:
C
5.
An EKG technician is placing the precordial electrodes on a patient who
is undergoing a routine 12-lead ECG. The technician palpates the
patient's sternum and identifies the fourth intercostal space immediately
to the right of the sternum. Which precordial electrode should be placed
at this anatomical location?
A. V1
B. V2
C. V4
D. V6
Answer: A
6.
During placement of the precordial electrodes, the technician correctly
identifies the fourth intercostal space immediately to the left of the
sternum. The technician wants to ensure that the electrode is positioned
according to standard 12-lead ECG placement guidelines rather than
simply placing it based on an estimated horizontal line. Which electrode
belongs at this location?
, 4
A. V1
B. V2
C. V3
D. V5
Answer: B
7.
An EKG technician is placing the precordial electrodes on an adult
patient and has already correctly positioned V1 and V2. The technician
now needs to place the electrode that is located midway between V2 and
V4 along the chest. Which electrode should be placed in this location?
A. V3
B. V4
C. V5
D. V6
Answer: A
8.
A patient is undergoing a standard 12-lead ECG, and the EKG
technician has identified the fifth intercostal space at the left
midclavicular line. The technician is reviewing the anatomical
landmarks to ensure that the precordial electrodes are positioned
correctly before starting the recording. Which electrode should be placed
at this location?
A. V2
B. V3
