This comprehensive 200-question practice exam is designed for NHA Certified Clinical Medical Assistant
(CCMA) candidates preparing for the 2026 certification test. It covers all key domains including EKG
interpretation, cardiovascular system, clinical patient care, phlebotomy, pharmacology, medication
administration, medical terminology, anatomy, administrative procedures, HIPAA/OSHA compliance,
and patient communication. Each question includes multiple-choice options, the correct answer, and a
concise rationale explaining the reasoning. This updated edition reflects the latest 2026 exam standards,
making it an essential study tool for certification success.
SECTION 1: EKG AND CARDIOVASCULAR SYSTEM (Questions 1-40)
1. What is the initial negative deflection produced by ventricular polarization?
1) The Q wave
2) The R wave
3) The T wave
4) The S wave
Correct Answer: 1) The Q wave
Rationale: The Q wave is the initial negative (downward) deflection produced by ventricular
depolarization. It represents the first phase of the QRS complex, which reflects electrical activity as the
impulse travels through the interventricular septum.
2. The first positive deflection produced by ventricular polarization is the __ wave.
1) The Q wave
2) The T wave
3) The S wave
4) The R wave
Correct Answer: 4) The R wave
,Rationale: The R wave is the first positive (upward) deflection produced by ventricular depolarization. It
represents the electrical activity as the impulse travels through the main ventricular muscle mass. The R
wave is typically the most prominent wave in the QRS complex.
3. Why should a patient who is in shock be positioned with the head lower than the rest of the body?
1) To prevent vomiting
2) To lower the heart rate and BPM
3) To encourage blood flow to the brain
4) To lower the chances of not passing out and have further injury
Correct Answer: 3) To encourage blood flow to the brain
Rationale: In shock, the Trendelenburg position (head lower than feet) is used to promote blood flow to
the brain and vital organs. This position uses gravity to help maintain cerebral perfusion when blood
pressure is critically low.
4. Refers to the movement away from the isoelectric line in an EKG.
1) Waveform
2) Segment
3) Interval
4) Complex
Correct Answer: 1) Waveform
Rationale: A waveform is the movement away from the isoelectric line on an EKG tracing. It represents
the electrical activity of the heart. The isoelectric line is the baseline from which waveforms deflect
upward (positive) or downward (negative).
5. Which of the following is not one of the patients rights provided by HIPAA?
1) Right to notice of a facility's privacy practices
2) Right to receive notice of all disclosures of PHI
3) Right to obtain the original medical record
4) Right to have access to, view, and obtain a copy of their PHI
Correct Answer: 3) Right to obtain the original medical record
,Rationale: Patients do not have the right to the original medical record. They have the right to access,
view, and obtain copies of their protected health information (PHI). The original record remains the
property of the healthcare provider or facility.
6. Which is not a vital sign of bodily function?
1) Weight
2) Pulse
3) Temperature
4) Respiration
Correct Answer: 1) Weight
Rationale: Weight is not considered a vital sign. The four primary vital signs are temperature, pulse,
respiration, and blood pressure. Weight is an important measurement but is classified separately as a
body measurement rather than a vital sign.
7. The myocardial cell's ability to contract in response to a stimulus.
1) Conductivity
2) Contractility
3) Automaticity
4) Excitability
Correct Answer: 2) Contractility
Rationale: Contractility is the ability of myocardial cells to contract in response to a stimulus. This
property is essential for the heart to pump blood effectively. Automaticity is the ability to generate
impulses spontaneously, conductivity is the ability to transmit impulses, and excitability is the ability to
respond to stimuli.
8. What part of the heart receives the deoxygenated blood from the body?
1) Right atrium
2) Left atrium
3) Right ventricle
4) Left ventricle
Correct Answer: 1) Right atrium
, Rationale: The right atrium receives deoxygenated blood from the body through the superior and
inferior vena cava. This blood is then pumped to the right ventricle, which sends it to the lungs for
oxygenation. The left atrium receives oxygenated blood from the lungs.
9. What is the relaxation period of the heart referred to as?
1) Systole
2) Diastole
3) Repolarization
4) Depolarization
Correct Answer: 2) Diastole
Rationale: Diastole is the relaxation period of the heart when the chambers fill with blood. Systole is the
contraction period when blood is pumped out. Repolarization refers to the electrical recovery phase,
and depolarization is the electrical activation phase of cardiac cells.
10. What is the normal duration of a PR interval on an EKG?
1) 0.04-0.10 seconds
2) 0.12-0.20 seconds
3) 0.20-0.30 seconds
4) 0.30-0.40 seconds
Correct Answer: 2) 0.12-0.20 seconds
Rationale: The normal PR interval is 0.12-0.20 seconds (3-5 small boxes). It measures the time from the
beginning of the P wave to the beginning of the QRS complex, representing atrial depolarization and
conduction through the AV node. Prolonged PR intervals may indicate first-degree heart block.
11. Which EKG lead is used as the ground lead?
1) Lead I
2) Lead II
3) Lead III
4) Right leg lead
Correct Answer: 4) Right leg lead
