BIOS255 Week 1 Case Study Revised 1/15/25 by: Dr. Shiffer Page 1 of 6 • Rh-positive (Rh+): If the Rh antigen is present on the red blood cells, the blood type is Rh-positive (e.g., A+, B+, etc.). • Rh-negative (Rh-): If the Rh antigen is absent, the blood type is Rh- negative (e.g., A-, B-, etc.). Blood Typing Test The blood typing test is used to determine an individual's ABO and Rh blood group. In this test, a sample of blood is mixed with antibodies that specifically react with A, B, or Rh antigens. Based on how the blood sample reacts, the blood type can be identified. Here’s how it works: • Anti-A antibodies are mixed with the blood sample to check for A antigens. • Anti-B antibodies are mixed with the blood sample to check for B antigens. • Anti-Rh antibodies are mixed with the blood sample to check for the Rh antigen. Example: In the following image let’s use Line 3 as an example. Line 3: Without Antibodies (Control): No agglutination With Anti-A Antibodies: No agglutination • Purpose: Used to replace lost fluids and clotting factors in cases of severe bleeding, burns, or liver disease. It’s also used in patients with clotting disorders. BIOS255 Week 1 Case Study Revised 1/15/25 by: Dr. Shiffer Page 3 of 6 • Function: Plasma is the liquid component of blood and contains water, electrolytes, proteins, hormones, and waste products. It helps maintain blood pressure and volume and carries clotting factors. • Indications: Bleeding disorders (e.g., hemophilia), burns, liver disease, or when clotting factors are low. 4. Cryoprecipitate • Purpose: A component of plasma used to treat bleeding due to low levels of clotting factors, particularly fibrinogen, factor VIII, and von Willebrand factor. • Function: Contains concentrated clotting factors that help with blood clotting. • Indications: Severe bleeding due to clotting factor deficiencies (e.g., in hemophilia or von Willebrand disease). 5. Granulocytes (White Blood Cells) • Purpose: Used in cases of severe neutropenia (low white blood cell count) or infections that are resistant to antibiotics. • Function: Granulocytes are a type of white blood cell that helps fight infections. • Indications: Life-threatening infections in patients with low white blood cell counts (e.g., after chemotherapy or bone marrow failure). Key Considerations for Nurses: • Compatibility: Ensure blood products are matched to the patient's ABO and Rh blood group to avoid dangerous reactions like agglutination. • Monitoring: Nurses must monitor the patient for signs of a transfusion reaction, which can include fever, chills, rash, or difficulty breathing. • Administration: Blood products are typically given through an intravenous (IV) line, and nurses should follow proper protocols for the 4. Emily could donate blood to individuals with which blood types? 5. Can Emily receive blood from an Rh-negative donor in the event that a transfusion is required? Why or why not?
