What is the primary purpose of a blood transfusion?

  1. To increase oxygen levels in the blood

  2. To replace lost blood volume

  3. To fight infections

  4. To regulate blood pressure


Correct Option: B
Explanation:

A blood transfusion is primarily performed to replenish blood volume and restore the body's ability to carry oxygen and nutrients to its tissues.

Which blood component is responsible for carrying oxygen?

  1. Red blood cells

  2. White blood cells

  3. Platelets

  4. Plasma


Correct Option: A
Explanation:

Red blood cells contain hemoglobin, a protein that binds to oxygen and transports it throughout the body.

What is the most common type of blood transfusion?

  1. Whole blood transfusion

  2. Red blood cell transfusion

  3. Platelet transfusion

  4. Plasma transfusion


Correct Option: B
Explanation:

Red blood cell transfusions are the most frequently performed type, as they are used to treat conditions such as anemia and blood loss.

What is the ABO blood group system?

  1. A classification system based on the presence or absence of A and B antigens on red blood cells

  2. A classification system based on the presence or absence of Rh factor on red blood cells

  3. A classification system based on the presence or absence of both A and B antigens and Rh factor on red blood cells

  4. A classification system based on the presence or absence of plasma proteins


Correct Option: A
Explanation:

The ABO blood group system classifies blood into four main groups: A, B, AB, and O, based on the presence or absence of A and B antigens on the surface of red blood cells.

What is the Rh factor?

  1. A protein found on the surface of red blood cells

  2. A protein found in plasma

  3. A protein found in white blood cells

  4. A protein found in platelets


Correct Option: A
Explanation:

The Rh factor is a protein found on the surface of red blood cells. Individuals who have the Rh factor are Rh-positive, while those who lack it are Rh-negative.

What is the significance of blood type compatibility in blood transfusions?

  1. To prevent immune reactions and transfusion complications

  2. To ensure the proper functioning of transfused blood cells

  3. To maintain blood pressure levels

  4. To regulate blood clotting


Correct Option: A
Explanation:

Blood type compatibility is crucial in blood transfusions to prevent immune reactions and transfusion complications. Incompatible blood transfusions can lead to hemolytic reactions, where transfused red blood cells are destroyed by the recipient's immune system.

What is the role of cross-matching in blood transfusions?

  1. To determine the compatibility of donor and recipient blood

  2. To measure the volume of blood to be transfused

  3. To check for the presence of infections in the donor's blood

  4. To monitor the patient's vital signs during the transfusion


Correct Option: A
Explanation:

Cross-matching is a laboratory procedure performed before a blood transfusion to ensure the compatibility of donor and recipient blood. It involves testing the recipient's serum against the donor's red blood cells to detect any potential immune reactions.

What are the potential risks and complications associated with blood transfusions?

  1. Immune reactions, such as hemolytic transfusion reactions

  2. Transfusion-related infections

  3. Circulatory overload

  4. All of the above


Correct Option: D
Explanation:

Blood transfusions carry potential risks and complications, including immune reactions (e.g., hemolytic transfusion reactions), transfusion-related infections (e.g., hepatitis, HIV), and circulatory overload (excessive fluid volume in the bloodstream).

What are the criteria for selecting a suitable blood donor?

  1. Healthy individuals between the ages of 18 and 65

  2. Individuals with a history of blood transfusions

  3. Individuals with certain medical conditions, such as diabetes or heart disease

  4. Individuals who have recently taken certain medications


Correct Option: A
Explanation:

Suitable blood donors are typically healthy individuals between the ages of 18 and 65 who meet specific health and lifestyle criteria, such as having a normal blood pressure, hemoglobin level, and no history of certain medical conditions or recent medication use that may affect the safety of the blood donation.

What is the process of leukoreduction in blood transfusions?

  1. Removing white blood cells from donated blood

  2. Adding white blood cells to donated blood

  3. Separating red blood cells from plasma

  4. Mixing different blood types together


Correct Option: A
Explanation:

Leukoreduction is the process of removing white blood cells from donated blood. This is done to reduce the risk of transfusion-related complications, such as febrile non-hemolytic transfusion reactions and transfusion-associated graft-versus-host disease.

What is the role of informed consent in blood transfusions?

  1. Obtaining the patient's consent before performing a blood transfusion

  2. Providing information about the risks and benefits of blood transfusions

  3. Ensuring that the patient understands the procedure

  4. All of the above


Correct Option: D
Explanation:

Informed consent is a crucial aspect of blood transfusions. It involves obtaining the patient's consent after providing them with comprehensive information about the risks, benefits, and alternatives to blood transfusions, ensuring that they understand the procedure and can make an informed decision.

What are the guidelines for blood storage and transportation?

  1. Maintaining specific temperature ranges

  2. Using sterile containers and equipment

  3. Following proper labeling and documentation procedures

  4. All of the above


Correct Option: D
Explanation:

Blood storage and transportation guidelines include maintaining specific temperature ranges to preserve the integrity of blood components, using sterile containers and equipment to prevent contamination, and following proper labeling and documentation procedures to ensure accurate tracking and traceability of blood products.

What is the role of blood banks in the blood transfusion process?

  1. Collecting, processing, and storing blood donations

  2. Distributing blood products to hospitals and clinics

  3. Performing compatibility testing and cross-matching

  4. All of the above


Correct Option: D
Explanation:

Blood banks play a crucial role in the blood transfusion process by collecting, processing, and storing blood donations, distributing blood products to hospitals and clinics, and performing compatibility testing and cross-matching to ensure safe and effective transfusions.

What are the ethical and legal considerations surrounding blood transfusions?

  1. Respecting patient autonomy and informed consent

  2. Ensuring equitable access to blood transfusions

  3. Protecting donor privacy and confidentiality

  4. All of the above


Correct Option: D
Explanation:

Blood transfusions involve ethical and legal considerations, such as respecting patient autonomy and informed consent, ensuring equitable access to blood transfusions regardless of socioeconomic status or discrimination, and protecting donor privacy and confidentiality.
