SBB Quizzes with Complete Solutions Graded A (1) 3 L is equal to how many deciliter - Answer-30 dl 6 ml of plasma containing a rare antibody that reacts 2+ undiluted. You need to make 10 mL with a 1+ reaction. How would you do it? - Answer-Use 5 ml of the 2+ plasma and 5 ml of the saline to dilute which should give a 1+ reaction 43.2 kg is equal to how many pounds? - Answer-95 lbs 500 g is equal to how many kg? - Answer-0.5 kg You have 50 g of NaCl and need to make a 25% solution. What is the volume of the final solution. - Answer-200 ml How would you prepare 400 ml of 8% NaCl? - Answer-32g of NaCl How would you prepare 20 ml of 6% bovine serum albumin from 30% BSA? - Answer-4 ml of 30% BSA in 16 ml of saline. 68 kg female hematocrit is 36% requires a 2 volume exchange transfusion. Calculate the volume of plasma needed for this exchange. - Answer-5225 ml Of the following findings, which would indicate that the individual had an anamnestic response to an antigen exposure? - Answer-IgG antibody was rapidly detectable in the circulation Infants receive a series of vaccinations for pertussis. After receiving the 2nd booster shot you would expect this to be the primary immunoglobulin produced - Answer-IgG A type O patient was erroneously transfused with type A RBCs. Hemolysis was evident in the post transfusion sample. This is an example of the activity involving: - Answer- Complement activation and the membrane attack complex Which portion of the antibody molecule is responsible for recognizing and interacting with the corresponding epitope. - Answer-Fab region A patient was tested for the IgG level of a specific antibody. He was found to have 1200 ug/ml of IgG antibody. Assuming no further immunization to the corresponding antigen, after how many days would you expect to have less than 200 of the original IgG antibody. - Answer-About 75 days In classical complement pathway, activated C1s acts on which substrate? - Answer- C4,C2 Susceptibility to complement mediated lysis is associated with which blood group antigen? - Answer-Cromer C3 convertase is made from which part of the complement cascade? - Answer-C4b2a You are performing an antibody screen using the tube method. After reading the antiglobulin phase you add IgG sensitized cells and get a negative reaction. What is the possible explanation - Answer-Added another reagent instead of AHG reagent What is the antiglobulin that appears after a parasitic infection? - Answer-IgE This term refers to the initial forces of attraction between an antibody binding site and its corresponding antigen - Answer-Affinity
