HOWARD – IMMUNOHEMATOLOGY 4TH EDITION STUDY QUESTIONS. What is the FDA’s primary responsibility in blood banks? a. Enforce the Code of Federal Regulations b. Conduct inspections of transfusion facilities for compliance c. License all personnel within the blood bank d. Provide continuing education credits  The Code of Federal Regulations outlines the legal requirements of the blood bank. 2. Donor records are legal documents and permanent medical records. How are errors properly corrected? a. Erasing the error and correcting the information in red ink b. Drawing many lines through the error and dating the error c. Drawing a single line through the error, correcting and dating the error, and initialing the correction d. Write over the error and date the correction  Good documentation requires the drawing of a single line through the error, correcting and dating the error, and initialing the correction. Some policies also require the reason for the correction to be documented. 3. What area does the Centers for Medicare and Medicaid Services (CMS) regulate? a. Donor testing only b. All laboratory testing c. All laboratory testing including research d. Recipient testing only  CMS regulates all laboratory testing (except research) performed on humans in the United States. The Clinical Laboratory Improvement Amendments of 1988 were enacted to ensure safe and accurate laboratory work. CMS issues a certification to laboratories or other test sites performing clinical tests on human samples. 4. Select the statement that BEST describes Good Manufacturing Practices (GMPs). a. Apply to the blood bank and not the transfusion service b. Include SOP and written record guidelines but not computerized record guidelines c. Do not apply to supplier qualifications d. Regulations that itemize what needs to be done without specifying how  Good Manufacturing Practices are performed in blood banks and transfusion services as part of QA and are legal requirements established by the FDA. These regulations itemize “what” needs to be done without necessarily specifying “how.” In other words, each organization must determine the best way to implement all these practices.

She was wearing her new large hoop earrings and gold bangles. Her shoes were new leather sneakers for comfort. Did she violate any safety rules for personal attire? a. No, she met all safety requirements. b. Yes, her hair was too long to work in the lab. c. Yes, her shoes were not made of nylon. d. Yes, she had excessive jewelry that could be a problem.  Hair should be secured away from the face and off the shoulders. Jewelry should be kept to a minimum, and rings that could perforate gloves should not be worn. Open-toed shoes are not permitted in areas where blood exposure exists. Cosmetics should not be applied in the laboratory. 6. What is the minimum personal protective equipment needed when splashes are likely to occur in the laboratory? a. Lab coat, gloves, safety glasses b. Lab coat, gloves, protective apron c. Lab coat and gloves d. None of the above  Safety glasses or goggles should be worn when splashes are likely to occur during a task. Face shields offer greater protection because they protect the mouth, nose, and eyes. Face shields are made of shatterproof plastic and wrap around the face. 7. Where should biohazardous needles and glass materials be disposed? a. Biohazardous waste red plastic bag b. Regular trash can c. Leakproof solid plastic container (“sharps”) d. Any of the above  Needles and glass need a special hard plastic container for disposal called a sharps container. 8. A technologist in training noticed that the person training her had some food and water stored in her reagent refrigerator. Is this an acceptable practice? a. Yes b. No Food or drink should not be allowed in the blood storage or testing areas. TRUE/FALSE 1. The Food and Drug Administration classifies blood as a drug.

ANS: F  A prudent part of the safety procedure of the blood bank includes the policy that all employees must wear gloves when tasks are likely to involve exposure to blood. Gloves used in a contaminated area should not be worn to a “clean” area or when using or touching telephones, doorknobs, or computer terminals. Gloves should be discarded after use and never washed.

Select the cells that will undergo transformation to become plasma cells. a. Neutrophils b. T lymphocytes c. B lymphocytes d. Monocytes  B lymphocytes have the ability to transform into plasma cells and produce antibodies, which is considered a humoral response. 2. What process is described by the engulfment of antibody-coated red cells? a. Lysis of cells b. Binding to cells or antigens c. Agglutination d. Phagocytosis  Phagocytosis removes antibody-coated red cells from the circulation through the mononuclear phagocyte system (also known as reticuloendothelial system). 3. Select the sources of antigen for immunohematology testing. a. Patient red cells and plasma
