Students have asked these similar questions
Antihistamines are used to treat cell-mediated hypersensitivity.
a. True
b. False
A nurse administering chemotherapy through a peripheral IV notices a red streak at the IV site and the patient reports itching sensationThe IV has a robust blood return. What does the nurse suspect?A.Hypersensitivity reactionB.ExtravasationC.Flare reactionD.Venous irritation
Explain why each choice (a-d) is correct or incorrect.
Allergens differ from antigens because
a. Allergens produce an abnormally large immune response to what is an otherwise harmless particle.
b. Allergens do not involve the leucocytes, they simple stimulate the inflammatory response.
c. Allergens are only active seasonally and are generally harmless to the body.
d. Allergens are primarily plant derived while antigens are bacterial or viral in nature.
