Definition

treatment for hypoglycemia:

CHECK

1.check pt blood glucose-

a. if more than 70, investigate other causes and S/S

b. if less than 70, begin hypoglycemic reatment

3. if no way to check blood glucose is around but patient presents symptoms-begin hypoglycemic treatment


TREAT

1. hypoglycemia is treated with 15-20 g of a simple fast acting carbohydrate: 4-6 fruit juice, 8 oz soft drink, or low fat milk

2. avoid things with fat if you can like candy bars, cookies, and ice cream bc this slows sugar absorption

3. avoid overtreatment to prevent hyperglycemia

4.check blood gluose after 15 minutes

    a. if still below 70, after 2 or 3 [15-20 g simple carb treatments] contact physician

Term
central & peripheral lymphoid organs
Definition
central:thymus & bone marrow
peripheral:spleen, tonsils, and lymphoid tissues
Term
lymphocytes are created in the bone marrow and then migrate to the _________ where its main job is too _________ and ________ T lymphocytes.
Definition
thymus, differentiate and mature
Term
thymus
Definition
important in the differentiation of T lymphocytes and their maturation. Important in cell-mediated response
Term
what happens to the size of the thymus with age?
Definition
in a child it is large and it shrinks with size
Term
two important functions of lymph nodes
Definition
filtration of foreign material brought to the site and circulation of lymphocytes
Term
spleen
Definition
primary site for filtering out antigens in the blood. Has B and T lymphocytes, RBCs and macrophages
Term
tonsils
Definition
lymphoid tissue that protects the body surface from microorganisms
Term
mononuclear phagocytes are responsible for capturing, processing, and presenting antigens to ______ and ____________ that then trigger an immune response
Definition
T and B lymphocytes
Term
immunoglobulins
Definition
antibodies
Term
what do B lymphocytes differentiate into when activated? In turn what do these produce?
Definition
plasma cells; antibodies
Term
cells that migrate from the bone marrow to the thymus are
Definition
T-cells
Term
what are the two types of T cells?
Definition
Cytotoxic T cells (CD8)
Helper T Cells (CD4)
Term
natural killer cells are involved in which type of immunity? Are they T or B cell? What are they involved in?
Definition
cell-mediated; neither; killing of virus infected cells, tumor cells, and transplanted grafts
Term
During the beginning (acute) phase of inflammation, particularly as a result of bacterial infection, environmental exposure,[4] and some cancer, are one of the first-responders of inflammatory cells to migrate towards the site of inflammation. They migrate through the blood vessels, then through interstitial tissue, following chemical signals such as Interleukin-8 (IL-8), C5a, and Leukotriene B4 in a process called chemotaxis. They are the predominant cells in pus, accounting for its whitish/yellowish appearance.

are recruited to the site of injury within minutes following trauma and are the hallmark of acute inflammation.
Definition
neutrophils
Term
cytokines
Definition
soluble factors secreted by WBCs that act as messengers between the cell types for proliferation, diffrentiation, secretion, and activity
Term
humoral immunity
Definition
antibody-mediated immunity
Term
cell mediated immunity vs humoral immunity
Definition
cell mediated initiated through specific antigen recognition by T cells and humoral is through B cells
Term
what are the effects of aging on the bone marrow? what however does decrease causing a suppressed humoral immunity response?
Definition
no changes to bone marrow, immunoglobin supression
Term
hypersensitivity reactions; what is an example?
Definition
hypersensitivity reactions: overactive immune response against antigens that attacks own tissues causing damage

autoimmune disease is a hypersensitivity reaction, you react against your own antigens bc you failed to recognize your own proteins
Term
how many types of hypersensitivity reactions are they? Which are humoral, which are cell-mediated?
Definition
I-IV; I-III are humoral, IV is cell mediated

Definition
has been effectively used to treat autoimmune diseases; separates blood and removes on the components
