A patient who has never experienced a reaction to a bee sting comes into the emergency department with intense edema and redness at the site of the sting. The nurse realizes that this patient is demonstrating which type of immune response?
1. mobilization of lymphocytic memory T cells
2. activation of granulocytes
3. creation of neutrophils
4. circulation of eosinophils
Correct Answer: 1
T lymphocytes mature into active helper T cells, cytotoxic T cells, or memory T cells. Memory cells stay inactive, sometimes for years, but activate immediately with subsequent exposure to the same antigen. They then proliferate rapidly and produce an intense immune response. Memory cells are responsible for providing acquired immunity. Granulocytes protect against harmful microorganisms during a period of acute inflammation. Neutrophils are responsible for phagocytosis and chemotaxis. Eosinophils are also responsible for phagocytosis and provide protection against parasites.
