With Verified Answers
Explain the challenges of diagnosing autoimmune disorders.
Diagnosing is made by history, physical, and serological findings. Since some blood tests are more
genetic, results can be imprecise. Markers can be elevated in the presence of other diseases. Criteria
for diagnosis: evidence of an autoimmune reaction, immunological findings are not second to other
conditions, and no other causes are found.
Which type of immunity is characterized by the development of a specific response to an antigen?
A. Innate immunity
-> B. Adaptive immunity
C. Autoimmunity
D. Active immunity
What allows the lymphocyte to differentiate between self and foreign molecules?
A. Antigen presenting cells
B. Regulatory cells
-> C. Major histocompatibility complex (MHC) molecule
D. Effector cells
T lymphocytes produce what type of immunity?
Cell-mediated
Which immunoglobulin passes immune factors from the mother to the fetus?
A. IgM
B. IgA
-> C. IgG
D. IgD
E. IgE
Which cell type is an early responder and the most abundant in the body?
A. Lymphocytes
B. Eosinophils
C. Basophils
-> D. Neutrophils
Which is NOT a finding consistent with Graves' disease?
A. Exophthalmos
-> B. Hypothyroidism
C. Hyperthyroidism
D. Goiter
E. Corneal ulceration
A 9-year-old boy with a peanut allergy was exposed to peanuts. He presents to the emergency room
with an anaphylactic reaction. (1) What symptoms might he present with? (2) Does the quantity of
exposure mean he will have a more severe reaction? (3) What is the initial immediate treatment? (4)
What are 2 things people with anaphylaxis should always carry?
1) shortness of breath, skin redness/hives, abdominal cramping
2) quantity of the exposure does NOT play role on how sever the reaction can be
