TOPICS COVERED A+
SECTION 1: ANATOMY & PHYSIOLOGY
Q1. The forearm vein most commonly used for venipuncture is the:
A. Cephalic vein
B. Median cubital vein
C. Basilic vein
D. Radial vein
Answer: B
Rationale: The median cubital vein is the preferred site for venipuncture because it
is usually large, well-anchored, and less likely to roll. It has fewer nerve endings,
causing less pain, and is positioned away from the brachial artery, reducing the
risk of arterial puncture .
Q2. The smallest veins in the human body are known as:
A. Arterioles
B. Capillaries
C. Venules
D. Venae cavae
Answer: C
,Rationale: Venules are the smallest veins. They collect blood from capillaries and
gradually merge to form larger veins. Arterioles are the smallest arteries, and
capillaries connect arterioles to venules .
Q3. The aorta branches into smaller divisions called arteries, which in turn
branch into even smaller divisions called:
A. Venules
B. Arterioles
C. Capillaries
D. Veins
Answer: B
Rationale: The aorta → arteries → arterioles → capillaries → venules → veins →
vena cava. Arterioles are the smallest arteries and regulate blood flow into the
capillaries .
Q4. Characteristics of capillaries include:
A. Having thin walls
B. Forming microscopic pathways
C. Connecting arterioles with venules
D. All of the above
Answer: D
Rationale: Capillaries have single-layer endothelial walls for gas/nutrient
exchange, form microscopic networks called capillary beds, and serve as the
bridge between arterioles and venules .
Q5. An artery can be distinguished from a vein because an artery will be:
A. Flattened
B. Blue in color
,C. Pulsating
D. Superficial
Answer: C
Rationale: Arteries carry blood away from the heart under high pressure, creating
a palpable pulse. Veins carry blood toward the heart under low pressure and do
not pulsate .
Q6. Neutrophils, eosinophils, basophils, lymphocytes, and monocytes are types
of:
A. Red blood cells
B. Plasma proteins
C. White blood cells
D. Platelets
Answer: C
Rationale: These five types of leukocytes (white blood cells) form the body's
immune defense. Neutrophils, eosinophils, and basophils are granulocytes;
lymphocytes and monocytes are agranulocytes .
Q7. The common name for the thrombocyte is the:
A. Red blood cell
B. White blood cell
C. Platelet
D. Plasma cell
Answer: C
Rationale: Thrombocytes are platelets—small, disc-shaped cell fragments essential
for hemostasis (blood clotting). They are produced from megakaryocytes in bone
marrow .
, Q8. The liquid portion of an anticoagulated blood sample is known as:
A. Serum
B. Plasma
C. Whole blood
D. Lymph
Answer: B
Rationale: Plasma is the liquid portion of blood that contains clotting factors
(fibrinogen). It is obtained when blood is collected in an anticoagulant tube. Serum
is the liquid portion after blood has clotted .
Q9. The instrument that measures blood pressure is called a:
A. Sphygmomanometer
B. Thermometer
C. Stethoscope
D. Centrifuge
Answer: A
Rationale: A sphygmomanometer measures blood pressure. Phlebotomists must
recognize this equipment and understand how blood pressure affects venipuncture
(e.g., avoiding the arm with an inflated BP cuff) .
Q10. The study of blood is known as:
A. Hematology
B. Histology
C. Cytology
D. Serology
Answer: A
