Question 1

A bone marrow transplant is performed for serious ailments,such as leukemia or cancer.

Accepted Answer

A bone marrow transplant is commonly used as a treatment option for serious illnesses such as leukemia, lymphoma, multiple myeloma, and some genetic disorders. Transplanting healthy bone marrow cells can replace damaged or diseased cells in the patient's bone marrow, restoring their ability to produce healthy blood cells.

Question 2

Heparin is a well-known coagulant.

Accepted Answer

Heparin is actually an anticoagulant, not a coagulant.

Question 3

Sedimentation rate is a blood test for AIDS.

Accepted Answer

Sedimentation rate (ESR) is not a specific blood test for HIV/AIDS. It measures the rate at which red blood cells settle in a tube of blood over time and is a nonspecific marker of inflammation or infection in the body. HIV/AIDS testing typically involves specific blood tests that detect the virus or antibodies produced in response to the virus.

Question 4

A bone marrow biopsy is used in the diagnosis of various blood disorders,such as anemia or leukemia.

Accepted Answer

A bone marrow biopsy involves removing a small sample of bone marrow tissue and examining it under a microscope to check for abnormalities in the production of blood cells. It is often used in the diagnosis of various blood disorders, such as anemia, leukemia, and lymphoma.

Question 5

People with AB blood can receive blood transfusions from people with all other types of blood.

Accepted Answer

People with AB blood have both A and B antigens on their red blood cells, but no antibodies against either antigen. Therefore, they can safely receive transfusions of any blood type.

Question 6

Heparin is a substance involved in allergic reactions.

Accepted Answer

Heparin is not involved in allergic reactions. It is a blood thinner used to prevent blood clots.

Question 7

A complete diagnostic of the chemical composition of blood is sometimes called an SMA,or sequential multiple analyzer.This was the name of the first machine that was used to analyze the blood,but now it is synonymous with the procedure.

Accepted Answer

The statement is true, as SMA is indeed the acronym for Sequential Multiple Analyzer, which was the name of the first machine used to analyze blood, but now it refers to the entire procedure for analyzing the chemical composition of blood.

Question 8

Monocytes are the largest cells in the blood.

Accepted Answer

Monocytes are the largest cells in the blood, measuring about 12-20 μm in diameter.

Question 9

Hemolysis is a type of hemophilia.

Accepted Answer

Hemolysis is not a type of hemophilia. Hemolysis refers to the breakdown of red blood cells, while hemophilia is a genetic disorder that affects the body's ability to clot blood.

Question 10

When a disease is in remission,it is on the increase.

Accepted Answer

When a disease is in remission, it means that its symptoms have improved or disappeared. Therefore, it is not on the increase.

Question 11

Vitamin K aids in clotting and is,therefore,an anticoagulant.

Accepted Answer

Vitamin K actually aids in clotting by promoting the synthesis of proteins necessary for the formation of blood clots. Therefore, it is not an anticoagulant but rather a coagulant.

Question 12

There are many types of anemias.

Accepted Answer

Yes, there are many types of anemias such as iron-deficiency anemia, sickle cell anemia, aplastic anemia, etc.

Question 13

Thalassemia is a hereditary blood disorder.

Accepted Answer

Thalassemia is a hereditary blood disorder where the body cannot produce enough hemoglobin, which leads to anemia and other health problems.

Question 14

Agranulocytes are important to immune system function.

Accepted Answer

Agranulocytes include lymphocytes and monocytes, which play crucial roles in the adaptive immune response and phagocytosis, respectively. Therefore, they are essential to immune system function.

Question 15

Arteries and veins exchange blood through the capillaries.

Accepted Answer

Capillaries are the smallest blood vessels in the body where exchange of oxygen, nutrients, and waste products occurs between arteries and veins.

Question 16

Neutrophils are the most plentiful red blood cells.

Accepted Answer

Neutrophils are not red blood cells but rather a type of white blood cell. Red blood cells are also called erythrocytes and they are responsible for carrying oxygen throughout the body. Neutrophils, on the other hand, are part of the body's immune system and help fight infections.

Question 17

Thrombolytic agents help to dissolve blood clots.

Accepted Answer

Thrombolytic agents, also known as clot-busting drugs, work by activating the body's natural clot-dissolving system to break down blood clots.

Question 18

Erythropoetin is produced in the liver.

Accepted Answer

Erythropoietin is primarily produced by the kidneys in response to low oxygen levels in the body. However, small amounts can also be produced by the liver.

Question 19

Anticoagulants aid in clotting,while coagulants prevent it.

Accepted Answer

Anticoagulants prevent clotting, while coagulants aid in clotting.

Question 20

Blood cultures are tests for viral infections.

Accepted Answer

Blood cultures are not tests for viral infections, they are tests to detect bacterial infections. For viral infections, other tests like serological assays or viral culture are used.
