NUR 612 EXAM 2 2026 LATEST UPDATE
QUESTIONS AND CORRECT VERIFIED
ANSWERS ALREADY GRADED A+
What is an example of type IV hypersensitivity reaction? - ANS-Metal allergies (nickel in
jewelry), poison ivy, TB screening
What mediates type I, II, and III hypersensitivity reactions? - ANS-antibodies
What mediates type IV hypersensitivity reaction? - ANS-T Lymphocytes
What is systemic lupus erythematosus? - ANS-Chronic, multisystem, inflammatory
autoimmune disease
What are characteristics of system lupus erythematosus? - ANS-production of large variety of
autoantibodies
What are clinical manifestations of system lupus erythmatosus? - ANS-Malar rash (redness
across cheeks), discoid rash (scaling), photosensitivaty, oral or nasypharyngeal ulcers,
nonerosive arthritis o two peripheral joints, serositis (plurisy, pericarditis), renal disorder,
neurological disorders (seizures), hematological disorders
What is the cure for systemic lupus erythematosis? - ANS-There is no cure. Goal of treatment is
to control symptoms and prevent further damage. NSAIDs, corticosterids, and
immunosupression
, What are exotoxins? - ANS-Produced during bacterial growth. Usually enzymes an can damage
cell membranes, activator second messengers, and inhibit protein synthesis
What preventative is available for endotoxic organisms? - ANS-Vaccines
What are endotoxins? - ANS-Lipopolysaccharides contained within the cell wall of gram
negative bacteria. They are released during lysis of bacteria
What can endotoxins lead to? - ANS-fatal (septic) shock
What do endotoxins do in the body? - ANS-Release vasoactive peptides and cytokines,
decrease oxygen delivery, produces cardiovascular shock, active clotting cascades, and can
cause DIC
What is the most notable acquired immune deficiency? - ANS-AIDS
What does AIDS do in the body? - ANS-Viral disease that depletes Th cells making individuals
susceptible to infection and malignancies
What are the three stages of stress? - ANS-1. Alarm/Reaction
2. Resistance/Adaption
3. Exhaustion
What happens in stage one of stress? - ANS-Alarm/Reaction: CNS is aroused and the
hypothalamus and SNS are activated
What happens in stage two of stress? - ANS-Resistance/Adaption: Fight or Flight kicks in.
Cortisol, Norepi, and Epi start flowing
