Question
Which of the following is a sign or symptom of a Type I hypersensitivity? A. Redness or rash B. Increased fluids leading to watery eyes and runny nose C. Smooth muscle contraction D. All of the above A Type II hypersensitivity is also called which of the following? A) Cell-mediated hypersensitivity B) Humoral hypersensitivity C) Cytotoxic hypersensitivity D) Allergy Which of the following occurs during a Type II hypersensitivity reaction? A) Antibodies attach to a person's own cells. B) T cells attack a person's own cells. C) IgE attaches to T cells and inflammatory mediators arc released. D) Soluble antigen-antibody complexes form triggering chronic inflammation and tissue damage Which of the following is an example of a Type II hypersensitivity? A) Tissue graft or transplant reaction B) Hemolytic disease of the newborn C) Allergies D) Systemic lupus erythematosus A Type III hypersensitivity is also called which of the following? A) Cell-mediated hypersenExplanation / Answer
91) Answer:
Generally, Type 1 hypersensitivity can occur in various parts of the body. But main parts are it effects nose(Hay fever) in which continuous sneezing, running nose and also redness of the eye and watery eyes due to allergic conjunctivitis, skin hives which include burning, redness of skin and rash, angioedema, anaphylaxis and further reactions lead to cause smooth muscle contraction.
and hence, D) All of the above is the right answer for this question
92) The answer is c) cytotoxic hypersensitivity.
Type 2 hypersensitivity also known as cytotoxic hypersensitivity or antibody-mediated hypersensitivity. the antibodies produced by the immune response bind to antigens on the patient's own cell surface who was affected with type 2 hypersensitivity.
93) a) The answer is A) antibodies attach to a person's own cells
Type 2 hypersensitivity is also termed as antibody mediated hypersensitivity mainly because of this factor.
94) The answer is D) Systemic lupus erythematosus.
Type 2 is tissue specific and can affect healthy cells.
95) The answer is D) Immune complex hypersensitivity.
Type 3 hypersensitivity reactions are characterized by tissue damage caused by the activation of complement in response to antigen-antibody (immune) complexes that are deposited in tissues.
96) The answer is D) soluble-antigen antibody complexes form triggering chronic inflammation and tissue damage.
Immune complex accumulation occurs in Type 3 hypersensitivity that has not been cleared by innate cells and thereby leads to inflammatory response and attraction of leukocytes takes place which further leads to immune complex diseases. tissue damage occurs through frustrated phagocytosis.
