HARTMAN PHLEBOTOMY EXAM BUNDLE 2026
Complete Practice Questions & Verified Answers with Detailed EXPERT
RATIONALE | Certified Phlebotomy Study Guide
• This study guide features 200 exam-style multiple-choice questions with verified
answers and detailed EXPERT RATIONALE, designed to mirror the format and
difficulty of the official Hartman/NHA Phlebotomy Certification Exam — use it by
attempting each question independently before checking the answer, then read the
EXPERT RATIONALE carefully to reinforce understanding.
• Each question is organized to test critical phlebotomy competencies including
venipuncture technique, specimen handling, anatomy, safety, and patient care —
making it ideal for timed self-quizzing, topic-by-topic review, or full mock exam
simulation in the final days before your certification.
Q1. What is the most common site used for venipuncture in adults?
A. Cephalic vein
B. Basilic vein
C. Median cubital vein
D. Dorsal hand vein
E. Femoral vein
✓ Correct Answer: C. Median cubital vein
,EXPERT RATIONALE: The median cubital vein is the preferred venipuncture site because
it is large, well-anchored, close to the surface, and least painful. It presents the lowest
risk of injury to surrounding nerves and arteries.
Q2. Which tube color is used for coagulation studies such as PT and aPTT?
A. Red
B. Green
C. Lavender
D. Light blue
E. Yellow
✓ Correct Answer: D. Light blue
EXPERT RATIONALE: Light blue top tubes contain sodium citrate, an anticoagulant that
works by binding calcium. This tube is specifically used for coagulation testing including
prothrombin time (PT) and activated partial thromboplastin time (aPTT).
Q3. What additive is found in a lavender/purple top tube?
A. Sodium citrate
B. Heparin
C. EDTA
D. Sodium fluoride
E. Thrombin
✓ Correct Answer: C. EDTA
EXPERT RATIONALE: Ethylenediaminetetraacetic acid (EDTA) is the anticoagulant in
lavender top tubes. It works by chelating calcium ions, preventing clotting. It is used
primarily for complete blood count (CBC) and blood smear tests.
,Q4. The tourniquet should not be left on the arm for more than how long?
A. 30 seconds
B. 1 minute
C. 2 minutes
D. 3 minutes
E. 5 minutes
✓ Correct Answer: B. 1 minute
EXPERT RATIONALE: A tourniquet should not be applied for more than 1 minute.
Prolonged application causes hemoconcentration, which can alter test results by
concentrating cells and large molecules in the blood sample.
Q5. Which of the following is the correct order of draw for evacuated tube
collection?
A. Yellow, Light Blue, Red, Green, Lavender, Gray
B. Light Blue, Yellow, Red, Green, Lavender, Gray
C. Red, Light Blue, Green, Lavender, Yellow, Gray
D. Yellow, Red, Light Blue, Green, Lavender, Gray
E. Green, Yellow, Light Blue, Red, Lavender, Gray
✓ Correct Answer: A. Yellow, Light Blue, Red, Green, Lavender, Gray
EXPERT RATIONALE: The CLSI-recommended order of draw is: Yellow (SPS/blood
cultures), Light Blue (citrate), Red/Gold (serum), Green (heparin), Lavender (EDTA), Gray
(fluoride/oxalate). This order prevents additive carryover contamination between tubes.
Q6. What angle should the needle be inserted during a routine venipuncture?
A. 10–15 degrees
, B. 15–30 degrees
C. 30–45 degrees
D. 45–60 degrees
E. 60–90 degrees
✓ Correct Answer: B. 15–30 degrees
EXPERT RATIONALE: A 15–30 degree angle is recommended for venipuncture. This angle
allows the needle to enter the vein cleanly without going through the posterior wall,
minimizing trauma and hematoma formation.
Q7. Which of the following conditions is a contraindication for venipuncture
at a specific site?
A. Mild dehydration
B. Presence of a tattoo near the site
C. Arteriovenous (AV) fistula on the same arm
D. Patient anxiety
E. Low blood pressure
✓ Correct Answer: C. Arteriovenous (AV) fistula on the same arm
EXPERT RATIONALE: An AV fistula is a surgically created connection between an artery
and vein, typically used for dialysis. Drawing blood from that arm can damage the
fistula and compromise the patient's dialysis access, making it a strict contraindication.
Q8. Which of the following best describes a hematoma?
A. Inflammation of a vein
B. Excessive bleeding under the skin caused by blood leaking into surrounding
tissue
C. Clotting inside a vein
