This study guide presents 100 multiple-choice questions organized into six sections aligned with the AMCA Phlebotomy Technician
Certification Examination content outline. Each question includes four answer options (A-D), the correct answer identified with the
[CORRECT] tag, and a detailed rationale explaining both why the correct answer is right and why the distractors are wrong. Use this
guide after initial content review to assess readiness, to identify knowledge gaps requiring further study, and to reinforce key
AMCA-aligned concepts including order of draw, venipuncture technique, safety and infection control, special population
considerations, and legal/ethical obligations.
Section 1: Phlebotomy Fundamentals and Anatomy
Role of the Phlebotomist - Medical Terminology - Circulatory System - Vascular Anatomy
Q1: The primary role of the phlebotomy technician is to:
A. Diagnose diseases from blood samples
B. Collect blood specimens for laboratory testing [CORRECT]
C. Perform laboratory tests on collected specimens
D. Interpret laboratory results for physicians
Correct Answer: B
Rationale: Phlebotomy technicians are allied health professionals whose primary role is to collect, label, and transport blood
specimens for laboratory analysis. Diagnosing disease, interpreting results, and analytical testing fall within the scope of
physicians, clinical laboratory scientists, or medical technologists - tasks outside the phlebotomist's scope of practice.
AMCA competency standards emphasize specimen integrity, patient safety, and professional communication during
collection.
Q2: A patient presents for a fasting blood glucose test but mentions she ate a cracker 2 hours ago. The
phlebotomist's most appropriate action is to:
A. Proceed with the draw since a single cracker is unlikely to affect results
B. Cancel the test entirely and reschedule for another day
C. Notify the physician or supervisor before collecting the specimen [CORRECT]
D. Draw the specimen and label it "non-fasting" without notifying anyone
Correct Answer: C
Rationale: When preanalytical conditions such as fasting status are not met, the phlebotomist must notify the ordering
provider or supervisor before specimen collection so an informed decision can be made. Drawing and labeling as
"non-fasting" without notification compromises result interpretation, while canceling or proceeding independently exceeds
the phlebotomist's scope of practice. The AMCA framework emphasizes professional communication and patient safety.

Q3: The medical prefix "hemo-" or "hemato-" refers to:
A. Heart
B. Half
C. Blood [CORRECT]
D. Hemoglobin only
Correct Answer: C
Rationale: The prefixes "hemo-" and "hemato-" derive from the Greek haima meaning blood and appear in terms such as
hematology (study of blood), hematoma (blood-filled swelling), and hemolysis (rupture of red blood cells). Cardi/o refers to
the heart, semi- means half, and hemoglobin is a specific protein rather than the general prefix meaning.
Q4: The suffix "-emia" in medical terminology indicates:
A. Inflammation
B. A blood condition [CORRECT]
C. Tumor or mass
D. Surgical removal
Correct Answer: B
Rationale: The suffix -emia means "blood condition" and is seen in terms such as anemia (deficiency of red blood cells),
bacteremia (bacteria in the blood), leukemia (cancer of blood-forming tissue causing abnormal white cells), and septicemia
(systemic blood infection). The suffix -itis denotes inflammation, -oma indicates a tumor or mass, and -ectomy signifies
surgical removal.
Q5: The laboratory abbreviation "CBC" stands for:
A. Complete Blood Count [CORRECT]
B. Comprehensive Blood Chemistry
C. Coagulation Blood Count
D. Complete Body Chemistry
Correct Answer: A
Rationale: CBC (Complete Blood Count) is one of the most frequently ordered laboratory tests and includes evaluation of
red blood cells, white blood cells, platelets, hemoglobin, hematocrit, and differential WBC count. Comprehensive Blood
Chemistry is not a standard term; the chemistry panel is typically called CMP (Comprehensive Metabolic Panel) or BMP
(Basic Metabolic Panel).
Q6: The combining form "phlebo-" means:
A. Artery
B. Vein [CORRECT]
C. Capillary
D. Heart
Correct Answer: B
Rationale: Phlebo- is the combining form meaning "vein," derived from the Greek phleps. It forms the basis of the term
phlebotomy (cutting into a vein for blood collection) and phlebitis (inflammation of a vein). Arteri/o refers to arteries,
capillar/o to capillaries, and cardi/o to the heart.
Q7: The human heart has how many chambers?
A. Two
B. Three
C. Four [CORRECT]

, AMCA Phlebotomy Technician Certification Exam Prep | Practice Questions and Study Guide
D. Five
Correct Answer: C
Rationale: The human heart contains four chambers: the right and left atria (upper receiving chambers) and the right and
left ventricles (lower pumping chambers). Deoxygenated blood enters the right atrium from the body and is pumped to the
lungs by the right ventricle; oxygenated blood returns to the left atrium and is pumped to the body by the left ventricle.
Q8: When selecting a venipuncture site in the antecubital fossa, the phlebotomist should first attempt the:
A. Basilic vein
B. Cephalic vein
C. Median cubital vein [CORRECT]
D. Dorsal metacarpal vein
Correct Answer: C
Rationale: The median cubital vein is the preferred first choice for venipuncture in the antecubital fossa because it is
typically large, well-anchored, superficial, and less prone to rolling or causing patient discomfort. The basilic vein, while
often large, is prone to rolling and lies near the brachial artery and median nerve, increasing complication risk. The cephalic
vein may be smaller and more difficult to access. Dorsal metacarpal veins are used only when antecubital veins are
unsuitable.
Q9: A phlebotomist notes that the patient's median cubital vein is not palpable but the cephalic vein is
prominent. The best action is to:
A. Attempt the median cubital anyway since it is the preferred site
B. Use the cephalic vein after palpating and evaluating it [CORRECT]
C. Switch immediately to a capillary puncture
D. Use the basilic vein to ensure a larger vessel
Correct Answer: B
Rationale: When the preferred median cubital vein cannot be palpated, the phlebotomist should evaluate the cephalic vein,
which is the second choice in the antecubital fossa. Capillary puncture is reserved for cases where venipuncture is
contraindicated or unsuccessful. The basilic vein is the third choice due to its proximity to the brachial artery and median
nerve; using it unnecessarily increases risk of injury.
Q10: Which sequence correctly describes the layers of a blood vessel wall, from outside to inside?
A. Tunica intima, tunica media, tunica adventitia
B. Tunica adventitia, tunica media, tunica intima [CORRECT]
C. Tunica media, tunica intima, tunica adventitia
D. Tunica intima, tunica adventitia, tunica media
Correct Answer: B
Rationale: Blood vessel walls (arteries and veins) have three layers: the outer tunica adventitia (connective tissue), the
middle tunica media (smooth muscle and elastic tissue), and the inner tunica intima (endothelium). Veins have thinner walls
and larger lumens than arteries, making them more easily collapsible - a key consideration when applying tourniquet pressure
during venipuncture.
Q11: The difference between serum and plasma is that:
A. Plasma contains fibrinogen; serum does not [CORRECT]
B. Serum contains red blood cells; plasma does not
C. Plasma is collected in EDTA; serum in heparin
D. There is no clinical difference
