patho exam 3 Flashcards
sodium lab value
136-145
potassium lab value
3.5-5
magnesium lab value
1.7-2.2
calcium lab value
9-11
phosphate
3.2-4.3
leukocytes
subcat: gran & agran
-neutrophils (gran)
-lymphocytes (agran)
-monocytes (agran)
-eosinophils (gran)
-basophils (gran)
immunity & inflammation
granulocytes
have cells w/ a nucleus in several lobes & granules -> they release mediators w/ immunity & inflammatory properties
agranulocytes
have a nucleus but have few to no granules -> still aid in immunity & inflammation
neutrophils
-1st to arrive
-bands (immature/left) & segs (mature/right)
-shift to left = acute phase
increase w/ acute bacteria infections & trauma
lymphocytes
-primary cells of immune response (T&B cells) that live in the lymphoid tissues
increase w/ chronic bacterial infection & actute viral infection
monocytes
phagocytosis
increase w/ bacterial infections & cancers (or could be lower for cancer)
eosinophils
increase w/ allergic rx or parasitic infections
worms, wheezes & weird disease
basophils
increase w/ allergic rx
low hgb indicates
bleeding, folate/b12 defic, cancers, kidney & liver disease
high hgb indicates
polycythemia, COPD, high alt, heavy smoking
low hct indicates
anemia, bleeding, bleeding disorders, fluid imbalances
high hct indicates
polycythemia, COPD, dehydration, shock, congenital heart disease
neutropenia precautions
-good hygiene
-avoid contact w/ sick people
-avoid raw fruits, veg, & grains
-keep doors closed
neutropenia
absolute count < 1000
infectious mononucleosis
infection of B lymphs caused by epstein barr virus
myelodysplastic syndrome
a group of related hematologic disorders characterized by a change in the quantity and quality of bone marrow elements (bone marrow failure)
myelodysplastic syndrome CM
(cytopenias) anemia, infection & spontaneous bleeding or bruising
leukemias
malignant neoplasms of cells originally derived from a single hematopoietic cell line (WBC that are unregulated and/or undifferentiated)
leukemic cells
-immature & unregualated
-proliferation in bone marrow
-circulate in blood
-infiltrate spleen, lymph nodes
leukemia classifications
according to their predominant cell (lymphocytic or myelocytic) & whether the condition is acute or chronic
what is the most common childhood leukemia
acute lymphocytic (lymphoblastic) leukemia
what is the most common leukemia in older adults
chronic lymphocytic leukemia
malignant lymphomas
neoplasms of cells derived from lymphoid tissues (hodgkin disease & nonhodgkin disease)
what cell is specific to hodgkin disease
reed-stenberg cell: a distinctive tumor cell found w/ lymph biopsy
hodgkin disease
characterized by painless, progressive, rubbery enlargement of single node or group of nodes, usually around the neck (good prognosis)
nonhodgkin disease
neoplastic disorder of lymphoid tissue that spreads early (to liver, spleen & bone marrow), characterized by painless, superficial lymphadenopathy
multiple myeloma
plasma cell cancer (B cells), atypical proliferation of one of immunoglobulins “M protein” which increases osteoclast activity unable to maintain humoral immunity
multiple myeloma characteristics
bone pain/fractures, impaired production of RBC & WBC
hypercalcemia
hyponatremia causes
-GI loses
-renal losses (diuretics)
-skin loses (burns, wounds)
-fasting diets, polydipsia (water intox)
-excess hypotonic fluid
hyponatremia S/s
-confusion/altered LOC
-anorexia, muscle weakness
-can lead to seeizures/coma
with Na, think
brain
hyponatremia treatment
-Na replacement (slowly)
-PO/IV
-IV fluids
-treat underlying problem
for dilutional, fluid restriction
hypernatremia causes
-IV fluid
-near drowning
-not enough fluid intake or too much water loss
-profound diuresis
will not get from eating too much salty food
hypernatremia S/s
-altered LOC/confusion, seizure, coma
-extreme thirst (hypereosmolality)
-dry, sticky mucous membranes
-muscle cramps
hypernatremia
-if H20 loss, add water
-if Na excess, remove sodium
