EXAM 4, LEVEL 3 NURSING SCF ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Immunity - Answer -Commonly defined as a physiological process that provides an individual with protection or defense of disease. Latin word: immuniswhich means exempt. B & T Lymphocytes - Answer -Produced in the bone marrow. B mature in bone marrow. T mature in the thymus gland. As person is challenged by specific antigens in life, lymphocytes to specific antigens emerge. If re-exposed body will have a more rapid response. A memory capacity for the immune system. Active Acquired immunity Antibody Production - Answer -Secreted by B lymphocytes Antibodies/immunoglobulins formed after B engulfs antigen and interacts with helper T's B makes identical copies of specific antibody Active Immunity - Answer -A form of acquired immunity in which the body produces its own antibodies against disease-causing antigens. Natural: Infection, exposed & body makes antibodies. Artificial: Vaccination given, then body makes antibodies. Passive Immunity - Answer -Natural: Maternal antibodies from Mother to child, (breastmilk), Artificial: infusion of monoclonal antibodies. This does not last forever 3-5 months Types of Antibodies - Answer -IgG: gone (feel better, but body has the memory of it), IgM: miserable (actively sick) immunoglobulins & antibodies are the same thing.

Most people will be immune, then chance of unvaccinated getting sick is LOW Vaccine program goals - Answer -Use widespread efforts to prevent specific infectious diseases from occurring in a population. Risk & benefits for the person & the community, Morbidity, mortality, financial cost & benefit. No vaccine is safe for all need to follow recommendations. Based on evidence based science CDC sets optimal schedules Live attenuated vaccines - Answer -Live pathogen, but weakened. May cause minor illness in rare cases cannot produce disease unless the person is immunocompromised. Ex: MMR & Varicella, Pregnant & immunosuppressed cannot get this type. Flu nasal spray is attenuatedno pregnant women Inactivated Vaccines - Answer -Inactivated or killed by heat or chemicals, unable to produce the disease. Some may only include a sub-unit of the microbe like a piece of protein from this. Boosters may be necessary to prolong immunity. Ex: Flu & Hep A. CANNOT infect the pt. w/a disease. May be symptomatic: fever. These are okay to give immunocompromised pt. Toxoid Vaccines - Answer -contain bacterial toxins that have been chemically modified to be incapable of causing disease. Spores can withstand high heat (c. diff. clostridium, etc) produce toxins. These vaccines induce the formation of antibodies can neutralize the real toxins. Ex. Tetanus & Diphtheria. Even if you have a break in the cornea this is a break in the skin Tetanus will be recommended. Recombinant Technology Vaccines - Answer -Contain partial viral subunits or proteins that are generated in the lab via biotechnology. Do not contain viral material-you cannot become infected/sick. Ex. Hep B & HPV Vaccines. COVID-19 Vaccine - Answer -mRNA gives instructions for our cell to make a harmless piece of what is called the "spike protein". The "spike protein" is found on the surface of the virus that causes COVID. mRNA degrades very quickly; Need assistance on Online classes, Exams & Assignments? Reach out for instant help!!
