N339 Exam 3.4 Exam 2025-2026
Questions and Correct Answers Graded A+
____ defined as a deficit of red cells, - answer--anemia
___, defined as an excess of red cells shown in - answer--polycythemia
An anemic patient has __due to the low oxygen-carrying capacity of the blood. -
answer--tissue hypoxia
In contrast to an anemic patiatent, a patient with polycythemia has increased
____and volume due to the increase in number of RBCs. - answer--blood viscosity
Aplastic anemia is a ____that is characterized by a reduction of hematopoietic
tissue in the bone marrow, fatty marrow replacement, and pancytopenia. The
decrease in functional bone marrow mass is usually caused by toxic, radiant, or
immunologic injury to the bone marrow stem cells, which causes a decrease in red
cells, white cells, and platelets, or pancytopenia - answer--stem cell disorder
The anemia of chronic renal failure occurs primarily from failure of the renal
endocrine function, which causes impaired ___and bone marrow compensation,
and secondarily from failure of the renal excretory function, leading to hemolysis,
bone marrow cell depression, and blood loss - answer--erythropoietin production
The anemia resulting from a deficiency of either vitamin B12 (cobalamin) or folate
is caused by a disruption in ____ of the blast cells in the bone marrow. - answer--
DNA synthesis
, Anemia B12 and Folat leads to a disruption which produces very large abnormal
bone marrow cells called - answer--megaloblasts
Iron deficiency, the most common nutritional deficiency in the world, is the most
common cause of anemia. Iron deficiency results in the unavailability of iron for
____. - answer--hemoglobin synthesis
Hemolytic anemias are characterized by decreased red cell survival rates. The
______are examples of a type of anemia caused by decreased red cell survival
rates - answer--thalassemias
The following describes which type of anemia: Under decreased oxygen tension,
hemoglobin S undergoes polymerization, which causes the red cell to assume a
sickled shape - answer--Sickle cell anemia
Which is worst sickle cell anemia homozygous or sickle cell trait heterogyous -
answer--sickel cell homozygous
Which type of anmeia causes chronic hemolytic anemia, recurrent painful
episodes, and acute and chronic organ dysfunction are the cardinal features of
sickle cell anemia. - answer--sickle cell anemia
Reversible sickled cell or irrevisable sickled cell: increase adhesivness and stick to
cell wall with membrants that are rough and easiably breakable - answer--
irrevisable sickled cell
