Define antigen and antibody in the context of blood transfusion.

• Antigen is a protein produced by the immune system, while antibody triggers an immune response.

• Antigen is a protein that neutralizes antibodies, while antibody is a substance that triggers an immune response.

• Antigen is a substance that triggers an immune response, while antibody is a protein produced by the immune system to neutralize antigens.

• Antigen is a substance that neutralizes antibodies, while antibody is a protein that triggers an immune response.

Explain the process of agglutination and its significance in blood typing.

• Agglutination is the process of identifying blood type using a microscope.

• Agglutination is the process of converting blood from one type to another to determine who can donate blood.

• Agglutination is the separation of antigens and antibodies, not relevant in blood typing.

• Agglutination is the clumping together of antigens and antibodies, used in blood typing to determine blood group.

What is the Rhesus factor and how does it affect blood compatibility?

• It is a type of blood clot that affects blood compatibility

• It is a type of white blood cell that affects blood compatibility and determines agglutination or no agglutination

• It is a vitamin that determines blood type

• It is a protein found on the surface of red blood cells and determines whether a person is Rh-positive or Rh-negative.

What is haemolytic disease of the newborn and how is it related to blood type incompatibility?

• It is related to blood type incompatibility by causing the mother's antibodies to attack the baby's red blood cells.

• It is related to blood type incompatibility by causing the mother's antibodies to attack the baby's white blood cells.

• It is related to blood type incompatibility by causing the baby's red blood cells to attack the mother's antibodies.

• It is related to blood type incompatibility by causing the baby's antibodies to attack the mother's red blood cells.

Explain the concept of blood group compatibility between a recipient and a donor.

• Matching the ABO and Rh blood group types between the recipient and the donor.

• Comparing the shoe size of the recipient and the donor

• Checking the zodiac signs of the recipient and the donor

• Matching the hair color between the recipient and the donor

What are the potential risks of mismatched blood transfusions?

• Allergic reactions, blood clots, and anemia

• Hypertension, diabetes, and cancer

• Immune reactions, hemolytic reactions, and transmission of infectious diseases

• Respiratory failure, organ damage, and sepsis

Describe the importance of blood typing and cross-matching in blood transfusions.

• To ensure compatibility between the donor's blood and the recipient's blood, and to prevent adverse reactions.

• To identify the recipient's favorite blood type

• To speed up the blood transfusion process

• To change the blood type of the recipient

Discuss the significance of knowing one's blood type in emergency situations.

• It helps determine the patient's favorite color

• It allows medical professionals to know the patient's zodiac sign

• It helps medical professionals determine the type of blood that can be safely transfused to the patient.

• It helps in deciding the patient's favorite food
