Module 6: Hypersensitivities, Infection, And Immune Deficiencies
A cancer patient develops an immune deficiency due to the course of the disease. This immune deficiency would be identified as which type?
Primary (congenital) immune deficiency is caused by a genetic defect, whereas secondary (acquired) immune deficiency is caused by another condition, such as cancer, infection, or normal physiologic changes, such as aging.
When mast cells degranulate, they release:
When stimulated by cell injury or the presence of microorganisms, the mast cell releases preformed mediators such as histamine.
A patient has a primary immune deficiency. In this case which are deficient?
Complement and phagocytes
Primary immune deficiencies are classified into five groups: defects of B lymphocytes, T lymphocytes, both B and T lymphocytes (combined), phagocytes, or complement.
Which laboratory value is most consistent with Bruton agammaglobulinemia?
Low levels of B cells
Bruton agammaglobulinemia has few or no circulating B cells, although T cell number and function are normal.
A patient has Wiskott-Aldrich syndrome. Which immunoglobulin whould the nurse expect to be low?
Wiskott-Aldrich syndrome is an X-linked recessive disorder, in which IgM antibody production is greatly depressed.
A patient has hypogammaglobulinemia from a B cell immune deficiency disorder. What should the nurse teach the patient about gamma globulin injections for this condition?
This treatment is only temporary.
The administration of gamma globulins can temporarily restore immune function (although these antibodies are only effective for 3 to 4 weeks).
