Question 1

Blood is composed of two parts: the plasma and the formed elements. The formed blood cells and cell fragments include all but which of the following?&#10;A) red blood cells (RBCs)&#10;B) white blood cells (WBCs)&#10;C) oxygen&#10;D) platelets

Accepted Answer

Blood is composed of two parts: the plasma and the formed elements (blood cells and cell fragments). The plasma is a pale yellow fluid composed mostly of water.

Question 2

Where are the three types of blood cells formed?&#10;A) hemopoietic tissue&#10;B) hemoglobin&#10;C) plasma&#10;D) blast cells

Accepted Answer

The three types of blood cells (RBCs, WBCs, and platelets) are made in hemopoietic tissue. The two types of hemopoietic tissue in the adult are the red bone marrow and the lymphatic tissue.

Question 3

Which type of blood cells is the most prominent in the body?&#10;A) white blood cells (WBCs)&#10;B) plasma&#10;C) platelets&#10;D) red blood cells (RBCs)

Accepted Answer

The RBCs are the most numerous of the blood cells.

Question 4

This is the component of the red blood cell to which oxygen attaches.&#10;A) organelles&#10;B) hemoglobin&#10;C) adenosine triphosphate&#10;D) mitochondria

Accepted Answer

As the RBCs circulate through the blood vessels in the lungs, oxygen (OS1U1B12S1U1B0) attaches loosely to the iron atom in the heme.

Question 5

Which hormone is secreted by the kidneys in order to stimulate the bone marrow's production of new red blood cells?&#10;A) erythropoietin&#10;B) prothrombin activator&#10;C) plasmin&#10;D) fibrin

Accepted Answer

The erythropoietin (EPO) stimulates the bone marrow to produce additional RBCs.

Question 6

This is a hereditary anemia that causes the red blood cells to form a rigid crescent shape.&#10;A) aplastic anemia&#10;B) deficiency anemia&#10;C) hemolytic anemia&#10;D) sickle cell anemia

Accepted Answer

Decreased oxygenation and cell death occur in a condition known as sickle cell disease. Instead of bending, the RBCs assume a sickle or C shape and block blood flow through the tiny blood vessels.

Question 7

What is the blood type of a universal donor?&#10;A) type A&#10;B) type B&#10;C) type O&#10;D) type AB

Accepted Answer

Type O blood can be given to people in all four blood groups. Type O blood is therefore called the universal donor.

Question 8

Which blood type is considered the universal recipient?&#10;A) type A&#10;B) type AB&#10;C) type B&#10;D) type O

Accepted Answer

Note also that someone with type AB blood can receive all four types of blood; this person is called a universal recipient.

Question 9

Polymorphs (polys), segs, and band cells are:&#10;A) platelets that become sticky and form a plug.&#10;B) erthrocytes that carry oxygen throughout the body.&#10;C) neutrophils.&#10;D) antibody-secreting agranulocytes.

Accepted Answer

Because of the many-shaped (polymorphic) nucleus, neutrophils are called polymorphs, or polymorphonuclear leukocytes (PMNs). Sometimes, they are simply called polys.

Question 10

Vasospasm, platelet plug, and blood coagulation are most related to which process?&#10;A) agglutination&#10;B) phagocytosis&#10;C) cross-matching&#10;D) hemostasis

Accepted Answer

Hemostasis involves three events: blood vessel spasm, the formation of a platelet plug, and blood clotting.
