INTRODUCTION
The purpose of this assessment is to evaluate the competency and readiness of
candidates seeking the National Center for Competency Testing (NCCT) Phlebotomy
Technician certification. This exam comprehensively assesses critical knowledge and
clinical skills across major domains, including patient identification, venipuncture
techniques, safety compliance, and specimen handling. Featuring a mix of foundational
multiple-choice questions and scenario-based problems, the exam emphasizes real-world
application, critical thinking, and clinical decision-making. Candidates must demonstrate
professional standards and strict adherence to regulatory guidelines to ensure patient
safety and high-quality laboratory results.
,SECTION ONE: QUESTIONS 1–100
Question 1
Which of the following is the most critical step in performing any phlebotomy procedure?
A. Selecting the correct needle gauge
B. Verifying patient identification
C. Applying the tourniquet tightly
D. Choosing the appropriate collection tube
🟢 B. Verifying patient identification
🔴 Explanation: Proper patient identification is the absolute foundation of patient safety
and laboratory accuracy. Misidentification can lead to catastrophic diagnostic and
treatment errors.
Question 2
A phlebotomist must perform a venipuncture on a patient with an intravenous (IV) line
running in the right arm. What is the preferred course of action?
A. Draw blood from a vein proximal to the IV site on the right arm
B. Collect the specimen from the left arm without an IV
,C. Turn off the IV pump for 30 seconds before drawing proximal to the IV
D. Collect the specimen directly from the IV line
🟢 B. Collect the specimen from the left arm without an IV
🔴 Explanation: Drawing blood from the opposite arm prevents specimen contamination
and dilution by the IV fluids. If both arms have IVs, the draw must be performed distal to
the IV line after it has been turned off by authorized nursing staff.
Question 3
Which antiseptic is considered the gold standard for cleaning a puncture site prior to
collecting a blood culture?
A. 70% isopropyl alcohol
B. Chlorhexidine gluconate
C. Hydrogen peroxide
D. Sodium hypochlorite
🟢 B. Chlorhexidine gluconate
🔴 Explanation: Chlorhexidine gluconate (or povidone-iodine) provides the deep residual
antimicrobial action necessary to eliminate skin flora that could contaminate a blood
, culture.
Question 4
What is the primary purpose of adding an anticoagulant to a collection tube?
A. To preserve glucose levels
B. To accelerate clot formation
C. To prevent the blood from clotting
D. To lyse red blood cells for testing
🟢 C. To prevent the blood from clotting
🔴 Explanation: Anticoagulants chemically inhibit the clotting cascade or bind calcium,
keeping the blood specimen in a fluid, whole-blood state.
Question 5
If a patient develops a hematoma during a venipuncture, what should the phlebotomist do
immediately?
A. Readjust the needle angle to go deeper
B. Have the patient pump their fist
