    Involved in a hemolytic blood transfusion reaction

    • WBC

    • RBC

    • P

    Correct Answer
    A. RBC
    Explanation
    The correct answer is RBC because hemolytic blood transfusion reaction involves the destruction of red blood cells (RBCs). This type of reaction occurs when the recipient's immune system recognizes the transfused RBCs as foreign and attacks them, causing their destruction. This can lead to various symptoms such as fever, chills, low blood pressure, and kidney damage. White blood cells (WBCs) and platelets (P) are not directly involved in this type of reaction.

    A person with this blood type can receive (by transfusion) only type 0- blood

    • AB+

    • O-

    • B+

    Correct Answer
    A. O-
    Explanation
    A person with blood type O- can receive only type O- blood because O- is the universal donor blood type, meaning it does not contain any antigens that can cause a transfusion reaction in the recipient. Since AB+ has both A and B antigens on their red blood cells, they cannot receive O- blood as it contains neither A nor B antigens. Similarly, B+ blood type individuals cannot receive O- blood as it lacks the B antigen. O- blood can be safely transfused to individuals with any blood type, making it the safest option for those with unknown blood types or in emergency situations.

    BLOOD TEST THAT INDICATES THE PERCENTAGE OF EACH TYPE OF WHITE BLOOD CELL IN A SAMPLE OF BLOOD

    • BONE MARROW BIOPSY

    • DIFFERENTIAL COUNT

    • HEMATOLOGY

    Correct Answer
    A. DIFFERENTIAL COUNT
    Explanation
    A differential count is a blood test that indicates the percentage of each type of white blood cell in a sample of blood. This test is commonly used in hematology to diagnose and monitor various conditions such as infections, autoimmune disorders, and leukemia. It provides valuable information about the immune system and can help healthcare professionals determine the underlying cause of a patient's symptoms. A bone marrow biopsy, on the other hand, involves taking a sample of bone marrow to examine the cells and is not specifically used to determine the percentage of each type of white blood cell. Hematology is the branch of medicine that deals with the study of blood and blood disorders.
