Certified Phlebotomy Technician (CPT) Exam – 2024/2025 – Updated
Practice Questions with Verified Answers
Description:
This document includes a comprehensive set of practice questions and verified answers for the
2024/2025 Certified Phlebotomy Technician (CPT) exam. Topics covered include venipuncture
techniques, capillary collection, patient preparation, safety and infection control, order of draw,
and handling of specimens. All questions are formatted to reflect the national CPT certification
exams and are designed to guarantee exam readiness and success.
1. The cardiac cycle: A complete heartbeat consisting of contraction and
relaxation of both atria and both ventricles.
2. What happens during the relaxation phase of the cardiac cycle?: All four
chambers are relaxed, the atrioventricular valves are open, and the semilunar
valves are closed.
3. How does blood flow from the right atrium to the right ventricle?: Blood
in the right atrium flows through the open tricuspid valve into the right ventricle.
4. How does blood flow from the left atrium to the left ventricle?: Blood in
the left atrium flows through the open mitral valve into the left ventricle.
5. What occurs when the atria contract during the cardiac cycle?: Atria
contract while ventricles stay relaxed, allowing additional blood to move from each
atrium into its associated ventricle.

, 6. What happens when the ventricles contract?: Ventricles contract while
atria relax. The right ventricle contracts, the tricuspid valve closes, and the
pulmonary valve opens, pushing blood into the pulmonary trunk.
7. What occurs when the left ventricle contracts?: The left ventricle contracts,
the mitral valve closes, and the aortic valve opens, pushing blood into the aorta. 8.
What happens during the relaxation phase of the ventricles?: Ventricles relax,
the semilunar valves close, and the atrioventricular valves open, beginning the
cycle again.
9. Hematocrit (Hct): The percentage of red blood cells in a sample of blood.
10. What is the primary function of hemoglobin?: To carry oxygen from the
lungs to the body tissues.
11. What does hemoglobin do with carbon dioxide?: It carries carbon dioxide
from the tissues to the lungs for release from the body.
12. Oxyhemoglobin: Bright red in color and carries oxygen.
13. Deoxyhemoglobin: Dark red in color and doesn't carry oxygen.
14. Adult male RBC count: Between 4.6 and 6.2 million RBC /microliter.
15. Adult female RBC count: Between 4.2 and 5.4 million RBC /microliter.
16. Healthy platelet count: Between 150,000 and 450,000 platelets per microliter
of blood.
17. WBC count: Normally between 5,000 and 10,000 cells.
18. Four major events in stopping the flow of blood:: 1. Blood vessel spasm.
2. Platelet plug formation.
3. Blood clotting.
4. Fibrinolysis.
