UAMS Hematology Exam #1 UPDATED
ACTUAL Questions and CORRECT
Answers
The study of blood cell formation, destruction, maturation, and number of blood cells which can
vary with disease or infection. - CORRECT ANSWER - What is hematology?
Blood, that may be clotted or anticoagulated with EDTA, heparin, or sodium citrate. -
CORRECT ANSWER - What is the most common specimen of hematology?
RBCs or erythrocytes, platelets or thrombocytes (PLT), WBCs or leukocytes, monocytes,
lymphocytes, and granulocytes which include banded or segmented neutrophils, basophils, and
eosinophils. - CORRECT ANSWER - What are the types of normal blood cells?
Complete blood count. RBCs, WBCs, platelets, hemoglobin, and hematocrit. - CORRECT
ANSWER - What is CBC and what does it count?
Mean cell volume measures the size of RBCs. Mean cell hemoglobin measures the weight of
hemoglobin in RBCs. Mean cell hemoglobin content measures the average concentration of
hemoglobin within RBCs. MCH and MCHC are increased with macrocytic anemia and
decreased with microcytic anemia. - CORRECT ANSWER - What does MCV stand for?
MCH? MCHC? What causes MCH and MCHC to be increased or decreased?
It categorizes cells in a 100-cell differential based on their maturity levels, to determine if a
disease or infection is present. - CORRECT ANSWER - What is white cell differential?
(diff)
Spleen, liver, thymus, lymph nodes, and bone marrow. The RES is a network of cells within
these tissues that help with the formation and destruction of RBCs to fight infection and prevent
bleeding, the metabolism of iron to give to RBCs to carry oxygen through hemaglobin,
inflammation, and immunity. - CORRECT ANSWER - What are the organs of the RES
and what is their function?
, Bone marrow, found within the cavities of cortical bones where the trabecular bone is also
found. In utero and at birth, most bones contain red bone marrow. At age 7, sites of bone marrow
begin to decrease and are restricted to proximal long bones, vertebrate, skull, sternum, ribs, and
pelvis. Adults have 50:50 ratio of red to yellow bone marrow. - CORRECT ANSWER -
What is one of the largest organs in the body and where is it found? Is the site of active bone
marrow always the same?
There are two types of bone marrow. Red that is actively producing RBCs, and yellow that is
inactive, mainly composed of fat cells. Red bone marrow is composed of extravascular cords that
contain all blood cell lineages, stem cells, progenitor cells, adventitial cells, and macrophages.
The cords are semi liquid and wedged between sinuses, supported by trabeculae. - CORRECT
ANSWER - What are the types of bone marrow? What is the composition of red bone
marrow?
Periosteal arteries that wrap around the central vein supply blood. The periosteal arteries branch
out to form capillaries and sinuses which hook up to larger veins to return the blood to
circulation. - CORRECT ANSWER - How does red bone marrow receive blood supply?
The cells are released as the body needs them. RBCs are kept at a steady rate. Adventitial cells
forming a discontinous line along the sinus will retract allowing the RBCs to exit into
circulation.
If needed, the yellow bone marrow can convert into red marrow to help make RBCs. -
CORRECT ANSWER - How are cells released from the bone marrow? What are
measures the body can take if RBCs aren't able to be supplied fast enough?
Lymphocytes, plasma cells, and macrophages. They play a role in producing new lymphocytes,
interacting with antigens and making antibodies, and ridding the blood of bacteria and debris. -
CORRECT ANSWER - What do the lymph nodes encapsulate? What do these do?
Spleen, it functions to act as a filter for blood to remove old or deformed RBCs from circulation.
These RBCs will either be culled (destroyed entirely) or pitted (macrophages bite out damaged
section). The spleen can also become a site of RBC production if needed and is also a holding
cell for platelets. - CORRECT ANSWER - What is the largest lymphoid organ? What
does it do?
