Introduction
The purpose of this assessment is to evaluate the competency, critical thinking, and
clinical readiness of candidates seeking certification as a Phlebotomy Technician. This
comprehensive examination measures essential skills and knowledge required to safely
perform blood collection procedures while minimizing patient risk and ensuring specimen
integrity. Structurally, the exam utilizes multiple-choice questions alongside complex,
,scenario-based items to simulate realistic clinical environments. Candidates must
demonstrate proficiency in regulatory compliance, infection control, order of draw, and
emergency response. Ultimately, this tool emphasizes real-world application and ethical
decision-making necessary to deliver high-quality patient care across diverse healthcare
settings.
Section One: Questions 1–100
1. Which of the following is the most critical first step a phlebotomist must take before
performing a venipuncture?
A. Assemble the collection equipment.
B. Positively identify the patient.
C. Apply the tourniquet to locate a vein.
D. Cleanse the puncture site with alcohol.
🟢 B. Positively identify the patient.
🔴 RATIONALE: Misidentification can lead to catastrophic diagnostic or treatment errors;
confirming the patient's full name and date of birth against the requisition and ID band is
the foundation of patient safety.
2. A patient refuses to have their blood drawn, stating they have a severe phobia of
needles. Which action should the phlebotomist take?
,A. Document the refusal and notify the ordering physician or nursing staff.
B. Convince the patient by explaining that the test is mandatory.
C. Enlist the help of another technician to hold the patient's arm still.
D. Proceed with the draw quickly while the patient is distracted.
🟢 A. Document the refusal and notify the ordering physician or nursing staff.
🔴 RATIONALE: Patients have the legal right to refuse medical procedures; proceeding
against their explicit will constitutes battery.
3. While performing a venipuncture using a evacuated tube system, you notice a
rapidly expanding hematoma forming at the site. What should you do immediately?
A. Instruct the patient to pump their fist to increase blood flow.
B. Adjust the needle depth to re-enter the vein lumen.
C. Remove the tourniquet, pull the needle, and apply firm pressure.
D. Complete the collection of the remaining tubes quickly.
🟢 C. Remove the tourniquet, pull the needle, and apply firm pressure.
🔴 RATIONALE: Prompt removal of the tourniquet and needle halts the escape of blood
into the surrounding tissue, minimizing tissue damage and complications.
4. If a blood culture collection is ordered alongside a complete blood count (CBC) and
a prothrombin time (PT), which tube must be collected first?
, A. Light blue top
B. Lavender top
C. Blood culture bottles
D. Gold top
🟢 C. Blood culture bottles
🔴 RATIONALE: Blood culture bottles must always be drawn first to prevent compromise
of sterility and minimize the risk of bacterial contamination from other tubes or non-sterile
stoppers.
5. Under CLSI guidelines, what is the maximum recommended depth for a heel
puncture on an infant?
A. 1.0 mm
B. 2.0 mm
C. 2.5 mm
D. 3.0 mm
🟢 B. 2.0 mm
🔴 RATIONALE: Puncturing deeper than 2.0 mm in an infant's heel poses a severe risk
of hitting the calcaneus bone, potentially causing osteomyelitis or osteochondritis.
6. A phlebotomist accidentally sticks themselves with a needle after completing a
venipuncture on a patient. What is the immediate priority?
