Term
Which leukocyte is the least common in a patient who is in homeostasis?
Definition
Basophil
Term
If a patient has a viral infection, which leukocyte would you expect to be high in number?
Definition
Lymphocytes
Term
Which leukocyte releases histamine?
Definition
Basophil
Term
A laboratory technologist did a differential count of the leukocytes and determined there to be 11 lymmphocytes out of 100 cells counted. Is this value too high or too low regarding normal lymphocyte counts?
Definition
This would be too low. 11 lymphocytes out of 100 = 11% (11/100 x 100 = 11%). A normal count is 20-40%
Term
A patient who is allergic to ragweed probably has a higher than normal number of ____________.
Definition
Eosinophils
Term
About 50-70 % of the leukocytes are __________. which specialize in attacking and destroying bacteria.
Definition
Neutrophils
Term
About 2-4% of the leukocytes are ________ which these cells respond during an allergic reaction and also during a parasite infection such as worm infestation.
Definition
Eosinophils
Term
Less than 1% of the leukocytes are ________. These cells release histamine that promotes inflammation that is involved in the healing of a wound.
Definition
Basophils
Term
About 2-8% of the leukocytes are ______. Two __________ can fuse together to produce a gigantic cell. This gigantic cell can engulf (phagocytize) rather large foreign particles. This gigantic cell is typically referred to as a macrophage.
Definition
Monocytes
Term
About 20-40% of the leukocytes are _______, which respond to bacterial infections as well as viral infections.
Definition
lymphocytes
Term
_________ are large cells that will fragment when they begin to leave the bone marrow and enter into circulation.
Definition
Megakaryoblasts
Term
Thrombocytes are now known as ______.
Definition
Platelets
Term
Platelets are derived from bone marrow cells called ______________.
Definition
Megakaryoblasts
Term
Coumadin does not change the consistency of blood and therefore really does not thin the blood. Rather, coumadin prevents blood from clotting by preventing the liver from using _______, which is necessary to make some of the blood clotting factors.
Definition
Vitamin K
Term
The condition of hemophilia is due to the lack of clotting factor number _______.
Definition
VIII
Term
Which anticlotting agent reduces the stickiness platelets and therfore reduces blood clotting?
Definition
aspirin
Term
The largest component of whole blood is ______.
Definition
plasma
Term
Lymphocytosis is a term that means having too many lymphocytes. Lymphopenia is a term that means not having enough lymphocytes. which term would apply if a patientt had 15% lymphocytes?
Definition
lymphopenia
Term
Neutrophilia is a term that means having too many neutrophils. Neutropenia is a term that means not having enough neutrophils. Which term would apply if a patient had 82% neutrophils?
Definition
Neutrophilia
Term
Eeythropoientin is produced by the ________.
Definition
Kidneys
Term
The stem cells of red blood cells are called?
Definition
erythroblasts
Term
Plasma makes up about _____% of whole blood.
Definition
55%
Term
The major component of plasma is?
Definition
water (92%)
Term
A cubic mm of blood contains about ______ erythrocytes.
Definition
5 million
Term
What triggers the release of erythropoietin?
Definition
a lack of oxygen going to the kidney cells
Term
Type A packed cells cannot donate to a type B patient because the ______ of the B patient will bind to the _______ of the donor.
Definition
a agglutinins; A agglutinogens
Term
Type O packed cells is considered to be the universal donor because the type O donor lacks. ________________.
Definition
agglutinogens
Term
Only Rh ______ people have the ability to manufacture the d agglutinins.
Definition
negative
Term
An excess number of leukocytes are called leukocytosis. Therefore, an excess number of monocytes would be called.
Definition
monocytosis
Term
A WBC count that shows a reduced number of leukocytes is called leukopenia. Therefore, a low number of lymphocytes would be called?
Definition
lymphopenia
Term
When basophils release ___________ during an allergy response, they typically couse the blood vessels lining the nasal cavity to dilate thus resulting in a runny nose.
Definition
histamine
Term
When oxygen binds to the _______ portion of hemoglovin, it causes the blood to become a bright red color.
Definition
iron
Term
Carbon monoxide is a deadly gas. It can couse death because carbon monoide has an affect on the respiratory cneters and also causes the blood cells to basically deliver less oxygen to the tissues of the body. This is because carbon monoxide binds to the ______ portion of the hemoglobin just as oxygen does.
Definition
iron
Term

Definition

Term
