Question 1 of 20
5.0/ 5.0 Points
Which of the following is/are important in the process named coagulation?
A. Coagulation is a complicated cascade of reactions that result in the formation of a mesh
of fibrin.
B. Coagulation can only occur in the presence of two or three different “clotting factors.”
C. A process which can reverse coagulation, named anticoagulation, can only occur when one or
more medications are administered to the body.
D. Neither an excess number of platelets nor having many too few platelets in the blood stream will
cause any serious reaction.
E. Coagulation is a very simple and straight-forward series of only two or three steps.

A. alpha globulins
B. albumin
C. immunoglobulin
D. gamma globulins
E. fibrinogen

Question 3 of 20
5.0/ 5.0 Points
In case an American needs an emergency blood transfusion, blood with the following blood type(s)
can be given without fear of agglutination?
A. O+
B. AB+
C. AB-
D. Blood with the same blood type as the person needing the transfusion.
E. Either C or D can be given.
Feedback:Good work; your answer is correct!
Question 4 of 20
0.0/ 5.0 Points
The blood type of a person’s blood depends on which of the following factors?
A. Which of the three antigens, A, B, and/or O, are located on the surface of the erythrocytes.
B. Which of two antigens, Rh+ or Rh-, are located on the surface of the erythrocytes.
C. Which of the two antigens, A or B or both, are located on the surface of the erythrocytes.
D. Whether or not the Rh antigen is found on the surface of the erythrocytes.
E. The blood type depends on both C and D.
Feedback:The ABO part of the blood type depends on which of the A and B antigens, or both, or
neither, are found on the surface of the erythrocytes. Whether the blood is Rh+ or Rh- depends on
whether or not the Rh antigen is present.

, Question 5 of 20
5.0/ 5.0 Points
Which of the following is/are true about the amount of oxygen being carried by RBCs?
A. Percent saturation of oxygen in the blood is normally monitored using a device known as a
pulse oximeter.
B. The normal pulse oximeter readings range from 95--100%.
C. Lower pulse oximeter readings, e.g. less than 95%, are indicative of the condition named
hypoxemia.
D. Many different diseases or conditions can result in hypoxemia.
E. All of the above are true.

Question 6 of 20
5.0/ 5.0 Points
What is the typical lifespan of a leukocyte?
A. The lifespan of a leukocyte typically is measured only in hours or days.
B. Many leukocytes can live indefinitely if they are in well-protected locations.
C. Because all leukocytes are unable to undergo mitosis (cell division), their lifespan is usually only
a few seconds.
D. The lifespan of a leukocyte is extremely variable, measuring in hours to years or decades.
E. The lifespan of a leukocyte is approximately 120-150 days.
Feedback:Good work; your answer is correct!
Question 7 of 20
5.0/ 5.0 Points
What is meant by the term anemia?
A. Anemia is said to exist when the total white blood cell is too low.
B. Anemia is defined as a deficiency in the number of red blood cells and/or hemoglobin.
C. There are only approximately four or five causes of anemia.
D. Anemia exists when the platelet count is so low that blood does not clot as quickly as it should.
E. Anemia always results from some very simple cause.
Feedback:Good work; your answer is correct!

A. albumin
B. plasma
C. hematocrit
D. white blood cells
E. All of the above are considered formed elements.
Feedback:Formed elements include red blood cells (RBCs), white blood cells (WBCs), and cell
fragments called platelets.
