NURS 8022 Module 3 Exam Questions
and Answers 2024
What maintains the osmolarity and acid-base balance of the blood -Answer-
✔Electrolytes and proteins
Functions of blood -Answer- ✔provide nutrients to cells, provide oxygen for cellular
metabolism, removes by-products, carries the cells that protect the body against
infection and invading organisms
3 groups of plasma proteins -Answer- ✔albumin, clotting factors (mostly fibrinogen),
lipoproteins (triglycerides, cholesterol, fatty acids)
Albumin -Answer- ✔function as carrier and control plasma oncotic pressure
serum -Answer- ✔plasma without clotting factors
pluripotential cells -Answer- ✔in the bone marrow and can differentiate into major blood
cells (red, white, platelets)
Erythrocytes -Answer- ✔red blood cells
Leukocytes -Answer- ✔white blood cells
Thrombocytes -Answer- ✔platelets
Most abundant cells of the body -Answer- ✔erythrocytes
Functions of Erythrocytes -Answer- ✔responsible for tissue oxygenation, contain
hemoglobin and carry gases and electrolytes, have biconcavity and reversible deformity
Life cycle of erythrocytes -Answer- ✔120 days, spleen replaces
Normal platelet count -Answer- ✔150,000-400,000
Platelets are formed from -Answer- ✔the fragmentation of megakaryocytes
Platelets are produced, stored, and removed by what -Answer- ✔produced by the bone
marrow, stored and removed by the spleen
life span of platelets -Answer- ✔5-9 days

, NURS 8022 Module 3
function of platelets -Answer- ✔essential for blood coagulation and the control of
bleeding
lymphoid organs -Answer- ✔sites of residence, proliferation, differentiation, and function
of lymphocytes and mononuclear phagocytes, link to the hematologic and immune
system
primary lymphoid organs -Answer- ✔thymus and bone marrow
secondary lymphoid organs -Answer- ✔Spleen, lymph nodes, tonsils, and Peyer
Patches of the small intestine
Hematopoiesis -Answer- ✔process of blood cell production in adult bone marrow or in
the liver/spleen of fetus
bone marrow -Answer- ✔primary site of residence of hematopoietic stem cells, also
called myeloid tissue
2 types of bone marrow -Answer- ✔red marrow (produce RBCs) and yellow marrow (do
not produce RBCs)
Stem cell pool -Answer- ✔The product of self-renewal that maintains the number of
pluripotent stem cells and partially committed progenitor cells
Bone marrow pool -Answer- ✔-contains cells that are proliferating and maturing in
preparation for release into the circulation
-mature cells are stored for later release into the peripheral blood
3 factors that increase Hematopoiesis -Answer- ✔(1) conversion of yellow bone marrow,
which does not produce blood cells, to hematopoietic red marrow by the actions of
erythropoietin (a hormone that stimulates erythrocyte production); (2) faster
differentiation of progenitor cells; and (3) faster proliferation of stem cells into progenitor
cells
Erythropoiesis -Answer- ✔production of red blood cells
Erythrocytes derived from -Answer- ✔erythroblasts
Erythrocyte maturation stimulated by -Answer- ✔erythropoietin
