EVALUATION OF LEARNING
White blood cell count, red blood cell count, platelet count, hemoglobin,
1.
hematocrit, differential white blood cell count, and red blood cell indices.
To transport nutrients to the tissues to nourish and sustain them; to pick up
2.
wastes from the tissues; to transport antibodies, enzymes, and hormones.
The red bone marrow of the ribs, sternum, skull, pelvic bone, and ends of
3.
the long bones of the limbs.
The immature form of an erythrocyte contains a nucleus. As the cell
4.
develops and matures, it loses its nucleus, causing the cell to acquire the
shape of a biconcave disk, thicker at the rim than at the center.
Arterial blood is bright red in color; venous blood is darker red in color.
5.
120 days.
6.
To defend the body against infection.
7.
In the tissues.
8.
They participate in the blood clotting mechanism of the body.

a. Adult female: 12 to 16 g/dl.
b. Adult male: 14 to 18 g/dl.
Anemia, hyperthyroidism, cirrhosis of the liver, severe hemorrhaging,
12.
hemolytic reactions, leukemia, Hodgkin’s disease.
To measure the percentage volume of packed red blood cells in whole
13.
blood.
14.
a. Adult female: 37% to 47%.
b. Adult male: 40% to 54%.
4500 to 11,000 white blood cells per cubic millimeter of blood.
15.
Acute infections such as appendicitis, chickenpox, diphtheria, infectious
16.
mononucleosis, meningitis, and rheumatic fever.
17.
a. Adult female: 4 to 5.5 million per cubic millimeter of blood.
b. Adult male: 4.5 to 6.2 million per cubic millimeter of blood.
Neutrophils, 50% to 70%.

MCV: Measures the average size of a single red blood cell.
MCH: Measures the average weight of hemoglobin within a red blood
cell.
MCHC: Measures the average concentration of hemoglobin within a
single red blood cell.
RDW: Measures any variation in size of the red blood cell.
A lack of iron in the diet known as iron-deficiency anemia.
A folic acid deficiency and a lack of vitamin B12 in the body known as
pernicious anemia.
Iron-deficiency anemia and thalassemia.
a. Automatic method: Faster and more convenient.
b. Manual: Allows for the closer inspection of abnormal white blood cells.
White blood cells are clear and colorless and must be stained to be
identified.
Basophil.
They have a multilobed nucleus that contains three to five lobes or
“segments.”
An immature form of a neutrophil.
Monocyte.
Lymphocytes are involved with the immune system and the production of
antibodies.
a. Hematocrit Hct.
b. Hemoglobin Hgb.
c. Differential cell count diff.
d. White blood cell count WBC.
e. Red blood cell count RBC.
The length of time that it takes for an individual’s blood to form a clot.
10 to 20 seconds.
The INR allows a patient’s PT test results to be compared regardless of the
testing reagent or laboratory test used to run the test.
0.8 to 1.2.
To inhibit the formation of blood clots in the body.
Heart attack, stroke, thrombophlebitis, recurring atrial fibrillation, heart
valve replacement with a mechanical valve, and patients exhibiting the
signs and symptoms of a coagulation disorder.
2.0 to 3.0.
To increase the clotting time to a level that prevents the formation of
blood clots without causing excessive bleeding or bruising.
Every 2 to 4 weeks.
Light blue–stoppered tube.
An underfilled tube results in an incorrect anticoagulant to blood ratio,
which can lead to inaccurate test results.
Patient does not have to make periodic visits to a laboratory or medical
office to have the test performed, and patient can test blood without a
lab order when conditions occur that may indicate a problem and
treatment can be instituted immediately.
