D Question 49 0 You are evaluating hospital records on a patient who died from sepsis caused by MRSA strain 300. The patient was infected two years ago with MRSA strain 500 and recovered after two weeks of antibiotic treatment. At the time of death, the patient had a large population of lymphocytes specific to aureus (MRSA strain 500). Which of the following explain WHY this population of specific lymphocytes failed to protect the patient: OA. The large population of lymphocytes specific to S. aureus (strain USA 500) were not responsive to IL-2 secretion B. The patient had no MRSA strain 300-specific TH cells for the secretion of IL-2 OC. MRSA strain 300 produced no specific antigens to induce an adaptive immune response OD. The large population of memory cells specific to the antigens of S. aureus (MRSA strain 500) could not undergo primary response OE. The large population of memory cells specific to the antigens of MRSA strain 500 could not recognize antigens of MRSA strain 300 Question 50 Viral meningitis results in cerebrospinal fluid (CSF) with high protein and low glucose values. O True O False Question 51 Immune system failure to recognize malignant cells may lead to cancer 2 pts O True O False 1 pts 1 pts
5 Question 47 Which of the following apply to memory cells: O A are long-lived antigen-specific lymphocytes O B. participated in the resolution of infection during primary response O C. remain in body without activity after clearance of the infectious agent until a subsequent infection with the identical agent OD. are responsible for protective immunity to specific agent O E. protect the host from subsequent illness with the specific infectious agent F. all of the above apply Question 48 Which of the following apply to Cytomegalovirus (CMV) infections in infants: 2 pts 2 pts O A. CMV affects 1-2.2% of births in U.S. and signs/symptoms include hearing loss and neurological impairment O B. CMV is associated with reactivation of the virus during the birthing process with -50% of infants developing disseminated herpes disease OC. CMV has a mortality rate in infected infants of approximately 54%. O D. CMV is associated with intestinal infection and potential loss of central nervous system (CNS) neurons O E. none of the above apply
