ESTUDYR
MT(AAB) BASIC KNOWLEDGE PRACTICE QUESTIONS:
HEMATOLOGY & COAGULATION EXAM
1. The primary function of red blood cells is to:
a) Defend against infection
✅b) Transport oxygen
c) Produce antibodies
d) Regulate coagulation
Rationale:
RBCs contain hemoglobin, which binds oxygen in the lungs and releases it to body tissues for
metabolism.
2. The main site of adult hematopoiesis is the:
a) Liver
b) Spleen
✅c) Bone marrow
d) Lymph nodes
Rationale:
In adults, red bone marrow (especially in the sternum, ribs, pelvis) produces all major blood
cells.
3. The average lifespan of an erythrocyte is approximately:
a) 30 days
b) 60 days
✅c) 120 days
d) 180 days
Rationale:
RBCs circulate about 120 days before being removed by macrophages in the spleen and liver.
4. The iron-containing pigment in red blood cells is:
, ESTUDYR
✅a) Hemoglobin
b) Myoglobin
c) Hemosiderin
d) Bilirubin
Rationale:
Hemoglobin carries oxygen via its heme groups, each containing one iron atom.
5. The process of white blood cells moving through capillary walls is called:
✅a) Diapedesis
b) Phagocytosis
c) Chemotaxis
d) Hematopoiesis
Rationale:
Diapedesis allows leukocytes to exit the bloodstream to reach sites of infection or
inflammation.
6. The anticoagulant used for most hematology tests is:
✅a) EDTA
b) Heparin
c) Sodium citrate
d) Potassium oxalate
Rationale:
EDTA preserves cellular morphology by chelating calcium, preventing clot formation.
7. Which of the following best describes the appearance of reticulocytes?
a) Mature RBCs with central pallor
✅b) Immature RBCs with bluish RNA remnants
c) Fragmented RBCs without nuclei
d) RBCs containing iron granules
