, Phlebotomy Exam 2026/2027: 135 Practice Questions
Section 1: Professional Characteristics & Fundamentals
1. A phlebotomist consistently arrives on time for shifts, admits a mistake in patient
identification, and treats all patients with compassion regardless of personal feelings. These
behaviors best demonstrate which combination of professional traits?
A. Technical skill, speed, and efficiency
B. Dependability, honesty, integrity, and empathy
C. Assertiveness, competitiveness, and independence
D. Analytical thinking, research skill, and documentation
Answer: B
Explanation: The scenario directly describes dependability (arriving on time), honesty/integrity
(admitting mistakes), and empathy/compassion (treating patients with care). These are
foundational professional characteristics for phlebotomists, alongside interpersonal skills and
professional appearance.
2. The primary function of the circulatory system is to:
A. Produce all formed elements including erythrocytes and leukocytes
B. Regulate body temperature through vasodilation and vasoconstriction
C. Deliver oxygen, nutrients, hormones, and enzymes to cells while removing cellular wastes
like carbon dioxide
D. Store excess glucose as glycogen for later energy use
Answer: C
Explanation: This is the core transport function of the circulatory system. While it does assist
with temperature regulation (B) and blood cells are produced in bone marrow (A), the primary
function is the delivery of essential substances to cells and removal of metabolic wastes.
3. The two major divisions of the circulatory system are:
A. Systolic and diastolic
B. Arterial and venous
,C. Pulmonary and systemic
D. Coronary and peripheral
Answer: C
Explanation: The pulmonary circulation handles blood flow between the heart and lungs for gas
exchange, while the systemic circulation manages blood flow between the heart and the rest of
the body.
Section 2: Cardiac Anatomy & Blood Flow
4. In pulmonary circulation, deoxygenated blood is carried from the right ventricle to the lungs,
and oxygenated blood returns to which chamber of the heart?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
Answer: B
Explanation: The pulmonary veins return freshly oxygenated blood from the alveoli of the lungs
to the left atrium, which then passes through the mitral valve into the left ventricle.
5. Gas exchange (oxygenation) occurs in which specific structures within the lungs?
A. Bronchioles
B. Pleural sacs
C. Alveoli
D. Pulmonary capillaries only
Answer: C
Explanation: Alveoli are the tiny, grape-like air sacs surrounded by pulmonary capillaries. This
is the precise site where oxygen diffuses into the blood and carbon dioxide diffuses out.
6. The tricuspid valve is located between the:
A. Left atrium and left ventricle
B. Right ventricle and pulmonary artery
, C. Right atrium and right ventricle
D. Left ventricle and aorta
Answer: C
Explanation: The tricuspid valve is the atrioventricular (AV) valve on the right side of the
heart. A common mnemonic is “Tri” (three cusps) and “Right” – people TRY to be RIGHT.
7. Trace the correct path of blood flow starting from the superior and inferior vena cavae:
A. Right atrium → tricuspid valve → right ventricle → pulmonic valve → pulmonary artery →
lungs → pulmonary vein → left atrium → mitral valve → left ventricle → aortic valve → aorta
B. Right atrium → pulmonic valve → right ventricle → tricuspid valve → lungs → left atrium
→ aortic valve → left ventricle → mitral valve → aorta
C. Left atrium → mitral valve → left ventricle → aortic valve → aorta → body → vena cavae →
right atrium → tricuspid valve → right ventricle
D. Right ventricle → pulmonic valve → pulmonary artery → lungs → pulmonary vein → left
ventricle → mitral valve → left atrium → aorta
Answer: A
Explanation: This is the complete and correct sequence of blood flow through the heart,
including all four chambers and four valves. Memorization of this sequence is essential for
understanding circulatory physiology.
Section 3: Blood Vessels & Composition
8. Which statement correctly describes the direction and oxygenation of blood in the vascular
system?
A. Arteries and arterioles carry deoxygenated blood toward the heart
B. Veins and venules carry oxygenated blood away from the heart
C. The aorta, arteries, and arterioles carry oxygenated blood away from the heart
D. The vena cavae carry oxygenated blood toward the heart
