CPT – Certified Phlebotomy Technician Exam 2026 | Most Tested
Questions & Verified Answers | Latest Update | Graded A+
1. What is the term for a substance that inhibits the growth of microorganisms
during blood collection?
Sterilizer
Antibiotic
Disinfectant
Antiseptic
2. If a patient is scheduled for a GTT, what preparation instructions should be
given to them prior to the test?
The patient should fast for at least 8 hours before the test.
The patient should drink plenty of water before the test.
The patient should eat a high-sugar meal before the test.
The patient should avoid all medications before the test.
3. If a patient is misidentified, what should happen?
The specimen should be discarded and recollected.
None of the above.
The specimen should be relabeled.
The specimen should be tested anyway.
4. In a scenario where a phlebotomy technician forgets to use an antiseptic
before a blood draw, what potential consequences could arise?
Faster sample processing time
, Higher quality blood samples
Increased risk of infection
Improved blood flow
5. Discuss the implications of delayed processing of microbiological tests on
patient outcomes.
Delayed processing is beneficial for quality control.
Delayed processing can lead to inaccurate results, which may affect
diagnosis and treatment.
Delayed processing has no impact on patient outcomes.
Delayed processing only affects the lab's workflow.
6. In a scenario where a patient experiences a traumatic injury causing a
laceration, how would hemostasis function to protect the patient?
Hemostasis would allow blood vessels to expand, leading to
increased bleeding.
Hemostasis would promote the formation of new blood cells to
replace lost blood.
Hemostasis would constrict the blood vessels at the injury site to
minimize blood loss.
Hemostasis would increase blood flow to the injury site to enhance
healing.
7. Describe the importance of using sterile techniques when collecting a urine
sample.
Using sterile techniques prevents contamination and ensures
accurate test results.
, Using sterile techniques increases the volume of urine collected.
Using sterile techniques is only necessary for blood samples.
Using sterile techniques is optional for routine tests.
8. In a medical context, what does the term 'assault' refer to?
A verbal threat made by a healthcare professional.
A physical attack resulting in injury.
The act of performing a medical procedure without consent.
An intentional act that causes fear of imminent harmful or offensive
contact.
9. What is the typical range of needle gauges used for blood donation?
16 to 18 gauge
20 to 22 gauge
18 to 20 gauge
14 to 16 gauge
10. The illegal intentional touching of another person without consent is known
as:
Fraud.
Malpractice.
Examination.
Battery.
11. What is an SST tube referring to?
, Dark green tube
Mint tube
Gold tube
Purple tube
12. If a laboratory technician mistakenly uses a green tube instead of a lavender
tube for a complete blood count (CBC), what impact might this have on the
test results?
The sample will be preserved for a longer duration.
The test results may be inaccurate due to the anticoagulant effect
of heparin.
The test results will be unaffected as both tubes are interchangeable.
The sample will be unusable due to clotting.
13. Describe the importance of wearing an N95 respirator in airborne isolation
settings.
The N95 respirator is a standard surgical mask used in all healthcare
settings.
The N95 respirator is primarily used for protecting against
bloodborne pathogens.
The N95 respirator filters out at least 95% of airborne particles,
providing protection against airborne pathogens.
The N95 respirator is only necessary for surgical procedures.
14. In a scenario where a patient has a low platelet count, what complication
might arise during a blood draw?
Difficulty in locating veins
