INTRODUCTION
This examination is designed to evaluate the essential competencies required of a certified
phlebotomy technician. It assesses knowledge of venipuncture procedures, patient identification,
infection control, specimen handling, and laboratory safety standards. The test includes multiple-
choice and scenario-based questions that simulate real clinical situations. Candidates are required to

SECTION ONE: QUESTIONS 1–80
════════════════════════════════════
1. What is the primary purpose of a tourniquet during venipuncture?
A. Increase arterial flow
B. Dilate veins for easier access
C. Prevent infection
D. Reduce pain
Correct Answer: B. Dilate veins for easier access
Explanation: A tourniquet temporarily restricts venous return, causing veins to become more
visible and easier to puncture.
2. Which vein is most commonly used for routine venipuncture?
A. Basilic vein
B. Femoral vein
, C. Median cubital vein
D. Cephalic vein
Correct Answer: C. Median cubital vein
Explanation: The median cubital vein is preferred due to its accessibility and lower risk of
complications.
3. What is the first step in patient identification?
A. Ask for diagnosis
B. Verify verbal confirmation only
C. Check wristband and ask full name
D. Review lab orders only
Correct Answer: C. Check wristband and ask full name
Explanation: Two identifiers are required to ensure correct patient identification and prevent
errors.
4. Which antiseptic is commonly used before venipuncture?
A. Alcohol-based chlorhexidine
B. Distilled water
C. Saline
D. Hydrogen peroxide only
Correct Answer: A. Alcohol-based chlorhexidine
Explanation: Chlorhexidine provides effective skin disinfection before blood collection.
5. What is the correct angle for venipuncture insertion?
A. 5–10 degrees
B. 15–30 degrees
C. 45–60 degrees
D. 90 degrees
Correct Answer: B. 15–30 degrees
Explanation: This angle allows smooth entry into the vein without penetrating through it.
6. What should be done if a patient faints during blood draw?
A. Continue procedure
B. Remove needle and lower patient
C. Ignore symptoms
D. Apply tourniquet tighter
Correct Answer: B. Remove needle and lower patient
Explanation: Safety requires immediate cessation and prevention of injury.
7. Which additive prevents clotting by binding calcium?
A. Sodium citrate
B. EDTA
C. Heparin
D. Fluoride
