Ms Joanne Rodi, an 18-year-old student Ms Rodi has been admitted to the unit from the operating room after surgery for multiple fractures in a car accident She is receiving a blood transfusion You document that her temperature has risen to 102°F and her respirations to 24 per minute and she has chills You take her BP; it has fallen to 90/60 What should you do? LO 11.9 Red Cell Antigens On the surfaces of red blood cells are molecules called antigens In the plasma, antibodies are present Each antibody can combine with only a specific antigen If the plasma antibodies combine with a red cell antigen, bridges are formed that connect the red cells together This is called agglutination, or clumping, of the cells Hemolysis (rupture) of the cells also occurs The antigens on the surfaces of the cells have been categorized into groups, of which two are the most important These are the ABO and Rhesus (Rh) blood groups ABO Blood Group Figure 11.14 shows the different combinations of antigens and antibodies in the different blood types The two major antigens on the cell surface are antigen A and antigen B (b) Type B blood Red blood cell Antigen A A person with only antigen A has type A blood A person with only antigen B has type B blood Antigen B A person with both antigen A and antigen B has type AB blood and is a universal recipient who can receive blood from any other type in the ABO system (c) Type AB blood Antibody anti-A Antibody anti-B Red blood cell A person with neither antigen has type O blood and is a universal donor, able to give blood to any other person no matter what that person’s blood type is Case Report 11.4 (continued) (d) Type O blood ▲ Figure 11.14 ABO Blood Types Keynotes In Miss Rodi’s case, she has type A blood and, by mistake, received type AB blood, which agglutinated in the presence of her anti-B antibodies Your immediate response is to stop the transfusion, replace it with a saline infusion, call your supervisor, and notify the doctor • All blood groups are inherited • Rh factor is an antigen on the surface of a red blood cell 384 CHAPTER 11 Blood The Language of Hematology LO 11.9, 11.A Word Analysis and Definition S = Suffix P = Prefix R = Root R/CF = Combining Form WORD PRONUNCIATION ELEMENTS DEFINITION agglutination ah-glue-tih-NAY-shun S/ P/ R/ -ation process ag- to -glutin- glue Process by which cells or other particles adhere to each other to form clumps antibody AN-tih-body P/ R/ anti- against -body substance Protein produced in response to an antigen antigen AN-tih-jen P/ R/ anti- against -gen to produce Any substance that can trigger an immune response infusion in-FYU-zhun P/ R/ in- in -fusion to pour Introduction intravenously of a substance other than blood Exercises A Review the elements in the above WAD before starting this exercise.

The information in this lesson will enable you to use medical terminology to: 11.6.1 Explain the diagnostic procedures used for hematologic disorders 11.6.2 Discuss the therapeutic disorders used for hematologic disorders 11.6.3 Describe the pharmacologic agents used in the treatment of hematologic disorders Abbreviations CBC ESR complete blood count erythrocyte sedimentation rate INR International Normalized Ratio MCH mean corpuscular hemoglobin MCHC mean corpuscular hemoglobin concentration MCV mean corpuscular volume PT prothrombin time PTT partial thromboplastin time LO 11.10 Diagnostic Procedures A complete blood count (CBC) measures the following: • The number of red blood cells (RBC count) • The amount of hemoglobin in the blood • The percentage of the blood composed of red blood cells (hematocrit) • Average red blood cell size (MCV) • Hemoglobin amount per red blood cell (MCH) • Amount of hemoglobin relative to the size of the red blood cell (MCHC) • The number of white blood cells (WBC count) • The types of white blood cells (WBC differential) • Platelet count Serum iron is the amount of iron in the blood Serum ferritin is the amount in the blood of the iron-protein complex that regulates iron storage and transport Erythrocyte sedimentation rate (ESR) is a nonspecific measure of inflammation Bone marrow is found inside the larger bones and contains cells that produce RBCs, WBCs, and platelets Bone marrow biopsy and aspiration are performed in the investigation of anemias, polycythemia, cancers (to determine if the cancer has spread to the bones), and bone marrow diseases Prothrombin time (PT), partial thromboplastin time (PTT), and International Normalized Ratio (INR) are used to evaluate bleeding and clotting disorders and to monitor anticoagulation therapies (see Lesson 11.4) A Monospot test is used to diagnose infectious mononucleosis caused by the Epstein-Barr virus It detects the presence of antibodies that the body developed in response to external antigens LO 11.11 Therapeutic Procedures A transfusion of blood or packed red blood cells (Figure 11.16) replaces lost red blood cells to restore the blood’s oxygen-carrying capacity During autologous donation and transfusion, people donate their own blood ahead of time to be given to them if necessary during a surgical procedure Bone marrow transplant is the transfer of bone marrow from a healthy, compatible bone marrow donor to a patient with aplastic anemia, leukemia, lymphoma, multiple myeloma, or other disease Hematopoietic stem cells are found in the bone marrow and are capable of generating all our blood cells such as red cells, white cells, and platelets In hematology, clinical trials to treat hemophilia and thalassemia with gene therapy are underway using allogenic cells from a compatible donor Gene therapy is an experimental technique to treat or prevent disease by replacing a mutated gene with a healthy copy, by inactivating a mutated gene that is functioning improperly, or by introducing a new gene into the body. ▲ Figure 11.16 Patient receiving blood transfusion. ©Dave Moyer 388 CHAPTER 11 Blood The Language of Hematology LO 11.10, 11.11 Word
