Question 28 You were caring for a patient with sepsis caused by MRSA strain 300 that dies as a result of the infection. Post-mortem (after death) tests reveal a small population of lymphocytes specific to MRSA strain 300 and no evidence of adaptive immune system dysfunction. Which of the following apply. OA the patient had no specific TH cells for the secretion of IL-2 OB. the patient had no ability to form memory cells OC. the patient did not have sufficient antigen-specific lymphocytes to destroy the MRSA pathogen OD. the patient did not have sufficient antigen presenting cells to display antigen to specific TH cels change for diapedesis to occur O E the patient did not have sufficient macrophage to secrete tumor necrosis factor alpha to maintain vascular Question 29 Which of the following apply to MHC Il molecules: OA are found on the surface of antigen presenting cells OB are found on the surface of all human cells OC are found on the surface of red blood cells OD. function to present (display) antigen for Tc cells OE function to present (display) antigen for B cells Question 30 2 pts Which of the following apply to allergic responses (Type I Hypersensitivities) OA anaphylaxis reactions that cause respiratory or circulatory disruptions O secretion in the presence of the allergen OD allergic signs and symptoms occur during the secondary response to the allergen Oal of the above apply 2 pts 2 pts
Question 25 Both B cells and T cells (T and Tc) have the ability to recognize different antigens due to: OA secretion of specific cytokines in response to specific antigen O B. secretion of antibody in response to specific antigen O C. ability to interact with MHC molecules O D. requirement for an antigen presenting cell (APC) O E different amino acid sequences producing different three-dimensional shapes of different BCRS and TCRs Question 26 All of the following apply to inactive subunit vaccines EXCEPT: O A use of a single antigen for the vaccine formulation O B. subunit vaccines may use capsular polysaccharide antigens O C. includes use of attenuated agents O D. will produce specific IgG and IgM O E. will produce specific TH cells OF. all of the above apply, no exception Question 27 2 pts All of the following are characteristics of the immune system EXCEPT OA mobility so that system can be concentrated at site of infection OB. communication between system components to ensure a coordinated response O C. refers to host defense reactions to non-self molecules introduced to body OD, composed of multiple cells (WBCs), proteins, and tissues systemically distributed O E all of the above apply, no exception 2 pts 2 pts
