Introduction
The Phlebotomy Certification Exam is designed to evaluate the competency, technical
proficiency, and clinical readiness of aspiring phlebotomists. This comprehensive
assessment focuses on essential skills including venipuncture techniques, specimen
handling, and rigorous adherence to safety protocols. By utilizing a blend of multiple-
choice questions and complex scenario-based inquiries, the exam measures foundational
medical knowledge alongside the ability to make sound professional decisions in a clinical
environment. Successful completion signifies an individual's mastery of the Order of Draw,
,patient rapport, and legal compliance, ensuring high-quality patient care and laboratory
integrity in real-world healthcare applications.
SECTION ONE: QUESTIONS 1–100
1. Which of the following is the most important step in performing a venipuncture?
A. Selecting the correct needle gauge
B. Identifying the patient
C. Applying the tourniquet correctly
D. Choosing the appropriate additive
🟢 B. Identifying the patient
🔴 Explanation: Proper patient identification is the bedrock of patient safety;
misidentification can lead to diagnostic errors, incorrect treatment, and potentially fatal
outcomes.
2. A phlebotomist is preparing to draw blood from a patient with a known allergy to
iodine. Which antiseptic should be used for a blood culture collection?
A. 70% Isopropyl alcohol
B. Povidone-iodine
,C. Chlorhexidine gluconate
D. Sodium hypochlorite
🟢 C. Chlorhexidine gluconate
🔴 Explanation: Chlorhexidine gluconate is the standard alternative for patients allergic to
iodine when a one-step sterile technique is required for blood cultures.
3. While performing a venipuncture, the phlebotomist notices a hematoma beginning to
form. What is the immediate next step?
A. Adjust the needle depth
B. Increase the angle of the needle
C. Remove the tourniquet and needle immediately
D. Apply more pressure to the site with the needle still in
🟢 C. Remove the tourniquet and needle immediately
🔴 Explanation: If a hematoma forms, the procedure must be stopped immediately to
prevent further tissue damage and nerve compression.
4. Which of the following veins is the first choice for venipuncture in the M-shaped
pattern?
, A. Basilic vein
B. Cephalic vein
C. Median cubital vein
D. Median vein
🟢 C. Median cubital vein
🔴 Explanation: The median cubital vein is the preferred choice as it is typically larger,
better anchored, and least likely to cause injury to underlying structures.
5. What is the purpose of the additive EDTA in a lavender top tube?
A. To promote clot formation
B. To preserve glucose levels
C. To prevent coagulation by binding calcium
D. To enhance serum separation
🟢 C. To prevent coagulation by binding calcium
🔴 Explanation: EDTA prevents clotting by chelating (binding) calcium, which is a
necessary component of the coagulation cascade.
6. A patient is required to fast for 8-12 hours before a draw. This is most common for
which of the following tests?
