TECHNICIAN EXAM QUESTIONS WITH
ANSWERS AND RATIONALES
1. Which organelle is primarily responsible for ATP production
in a eukaryotic cell?
A. Nucleus
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
Correct Answer: C. Mitochondrion
Rationale: Mitochondria generate most cellular ATP through
oxidative phosphorylation.
2. Which blood component is primarily responsible for oxygen
transport?
A. Platelets
,B. Erythrocytes
C. Leukocytes
D. Plasma proteins
Correct Answer: B. Erythrocytes
Rationale: Red blood cells contain hemoglobin, which binds and
transports oxygen.
3. What is the normal approximate lifespan of an
erythrocyte?
A. 7 days
B. 30 days
C. 120 days
D. 365 days
Correct Answer: C. 120 days
Rationale: Normal red blood cells circulate for approximately
120 days before being removed primarily by the spleen.
4. Which anticoagulant is commonly used for complete blood
counts?
,A. Sodium citrate
B. EDTA
C. Heparin
D. Sodium fluoride
Correct Answer: B. EDTA
Rationale: EDTA chelates calcium and preserves cellular
morphology, making it suitable for hematology testing.
5. Which anticoagulant is preferred for coagulation studies?
A. EDTA
B. Sodium citrate
C. Sodium fluoride
D. Oxalate
Correct Answer: B. Sodium citrate
Rationale: Sodium citrate reversibly binds calcium and is used
for tests such as PT and aPTT.
6. Which blood cell is normally the most numerous leukocyte?
, A. Eosinophil
B. Basophil
C. Monocyte
D. Neutrophil
Correct Answer: D. Neutrophil
Rationale: Neutrophils are normally the predominant
circulating white blood cells.
7. Which leukocyte is most strongly associated with allergic
reactions and parasitic infections?
A. Eosinophil
B. Neutrophil
C. Monocyte
D. Lymphocyte
Correct Answer: A. Eosinophil
Rationale: Eosinophils participate in allergic responses and
defense against many parasites.
