NHA CCMA Certification Comprehensive Study Guide
2026 | High-Yield Final Review
1. In a clinical setting, if a medical assistant needs to sterilize surgical
instruments, what should they ensure regarding the chemical sterilization
process?
They should only use disinfection methods.
They should ensure that the instruments are exposed to the
chemicals for a longer duration.
They should clean the instruments with soap before sterilization.
They should use a higher concentration of chemicals.
2. If a patient is experiencing severe anxiety and exhibits somatic tremors
during an EKG, what should a medical assistant do to ensure accurate
readings?
Ask the patient to hold their breath during the test.
Increase the sensitivity of the EKG machine to capture more detail.
Ignore the tremors as they do not affect the EKG results.
Calm the patient and provide reassurance to reduce anxiety and
minimize tremors.
3. If a patient has a condition that affects the pulmonary arteries, what impact
might this have on their oxygen levels?
It would increase oxygen levels in the blood.
It would have no effect on oxygen levels.
It could lead to decreased oxygen levels in the blood.
It would only affect carbon dioxide levels.
,4. Describe the primary purpose of using winged infusion sets in medical
procedures.
Winged infusion sets are used for drawing arterial blood.
Winged infusion sets are used for blood transfusions.
Winged infusion sets are primarily used for venipuncture on small
veins.
Winged infusion sets are used for administering medications.
5. Describe the pathway of blood flow from the right atrium to the right
ventricle.
The right atrium receives blood from the lungs and sends it to the left
atrium.
The right atrium receives oxygenated blood and sends it to the left
ventricle.
The right atrium collects blood from the aorta and sends it to the
body.
The right atrium receives deoxygenated blood and sends it to the
right ventricle.
6. What does the vertical axis on an EKG measure?
Heart rate
Duration of the heartbeat
Blood pressure
Amplitude of the electrical signals
,7. A patient presents with chest pain during physical exertion. What condition
might this indicate related to blood flow?
Ischemia
Anemia
Hypertension
Hyperlipidemia
8. What type of blood does the right ventricle receive from the right atrium?
Deoxygenated blood
Nutrient-rich blood
Waste-rich blood
Oxygenated blood
9. What is the medical term that describes the absence of urine production?
Oliguria
Dysuria
Polyuria
Anuria
10. Describe the significance of erythrocytes in the circulatory system.
Erythrocytes are involved in the immune response against pathogens.
Erythrocytes primarily function in the synthesis of hormones.
Erythrocytes are crucial for transporting oxygen to tissues and
organs, which is essential for cellular respiration and energy
production.
, Erythrocytes help in the digestion of food in the stomach.
11. Describe how the V1 to V6 leads contribute to the diagnosis of cardiac
conditions.
They only measure heart rate without providing diagnostic
information.
They help to diagnose various cardiac conditions by providing
different angles of the heart's electrical activity.
They assess the patient's respiratory rate.
They are used exclusively for monitoring blood pressure.
12. What is the primary reason for shock in a medical context?
Dehydration of body tissues.
Inadequate blood flow to the heart and subsequently to the rest of
the body.
Increased oxygen levels in the blood.
Excessive blood flow to the brain.
13. What phase of the cardiac cycle does the T wave represent in an EKG?
Atrial depolarization
Ventricular depolarization
Ventricular repolarization
Atrial repolarization
14. If a patient develops pericarditis, which symptom might they experience due
to inflammation of the pericardium?
Chest pain
