SECTION 1: EKG ACQUISITION & PATIENT
PREPARATION (Questions 1-20)
Question 1
What is the first step an EKG technician should take when preparing a patient
for a 12-lead EKG?
A) Apply electrodes to the chest
B) Verify the patient's identity using two identifiers
C) Calibrate the EKG machine
D) Cleanse the skin with alcohol pads
Correct Answer: B
Rationale: According to AHA standards, verifying the patient's identity using two
identifiers (e.g., name and date of birth) is the first step to ensure patient safety
and compliance with HIPAA regulations. This prevents errors in documentation
and ensures the correct patient receives the test.
Question 2
Where should the V1 electrode be placed for a standard 12-lead EKG?
A) Fifth intercostal space, left midaxillary line
B) Fourth intercostal space, right of the sternum
C) Fifth intercostal space, left anterior axillary line
D) Second intercostal space, left midclavicular line
Correct Answer: B
,Rationale: V1 is placed in the fourth intercostal space, right of the sternum. V2 is
placed in the fourth intercostal space, left of the sternum. V4 is placed in the fifth
intercostal space, midclavicular line. V3 is placed midway between V2 and V4.
V5 is placed in the fifth intercostal space, anterior axillary line. V6 is placed in
the fifth intercostal space, midaxillary line.
Question 3
Which electrode is placed in the fifth intercostal space, left midclavicular line?
A) V2
B) V4
C) V5
D) V6
Correct Answer: B
Rationale: V4 is placed in the fifth intercostal space, left midclavicular line. V1 is
placed in the fourth intercostal space, right of the sternum. V2 is placed in the
fourth intercostal space, left of the sternum. V5 is placed in the fifth intercostal
space, anterior axillary line. V6 is placed in the fifth intercostal space,
midaxillary line.
Question 4
The limb leads (I, II, III, aVR, aVL, aVF) are placed on the:
A) Chest
B) Arms and legs
C) Back
D) Abdomen
Correct Answer: B
Rationale: The limb leads are placed on the arms and legs: right arm (RA), left
arm (LA), right leg (RL), and left leg (LL). The chest leads (V1-V6) are placed on
the chest. The limb leads provide the frontal plane view of the heart.
,Question 5
What is the purpose of applying electrode gel or skin prep before placing
electrodes?
A) To reduce electrical impedance and improve signal quality
B) To mark the electrode placement sites
C) To prevent skin irritation
D) To warm the skin
Correct Answer: A
Rationale: Electrode gel or skin prep reduces electrical impedance and
improves signal quality. Proper skin preparation is essential for obtaining a
clear and accurate EKG tracing. Electrode gel improves conductivity between
the skin and the electrode.
Question 6
What is the normal paper speed for a standard 12-lead EKG?
A) 25 mm/sec
B) 50 mm/sec
C) 12.5 mm/sec
D) 100 mm/sec
Correct Answer: A
Rationale: The standard paper speed for a 12-lead EKG is 25 mm/sec. At this
speed, each small box represents 0.04 seconds, and each large box represents
0.2 seconds. At 50 mm/sec, each small box represents 0.02 seconds, and each
large box represents 0.1 seconds.
Question 7
What is the normal gain (amplitude) setting for a standard 12-lead EKG?
, A) 5 mm/mV
B) 10 mm/mV
C) 20 mm/mV
D) 15 mm/mV
Correct Answer: B
Rationale: The standard gain setting is 10 mm/mV. At this setting, a 1 mV signal
produces a 10 mm deflection. This standardization allows for consistent
interpretation across different EKG machines and settings.
Question 8
Which of the following is the correct placement for the right leg (RL) electrode?
A) Right lower abdomen
B) Right ankle
C) Right wrist
D) Right clavicle
Correct Answer: B
Rationale: The right leg (RL) electrode is typically placed on the right ankle (or
right lower calf). It serves as a ground electrode to reduce interference. The left
leg (LL) electrode is placed on the left ankle.
Question 9
Which of the following is the correct placement for the left arm (LA) electrode?
A) Left ankle
B) Left wrist
C) Left shoulder
D) Left chest
Correct Answer: B
