chpt 30 study guide

hematologic system

QuestionAnswer
production stimulated by hypoxia erythrocytes
increases indicate an increased rate of erythropoiesis reticulocytes
also known as segs, 50-70% wbc, first at injury site neutrophil
0-2% of wbc, release granules which cause inflammatory/allergic response basophils
immature cell is called a band neutrophils
increased in individuals w/allergies, makes up 2-4% of wbc eosinophils
primarily responsible for immune response, 4-8% of wbc count lymphocytes
30% stored in spleen, arises from a megacaryocyte plts
granulocytes include neutrophils, basophils, and eosinophils
nutrients essential for RBC production B12, iron, and folic acid
accumulation d/t obstruction of lymph fluid is known as... lymphedema
filters of the hematoligic system include the... liver, spleen, and lymph nodes
iron is stored in the body in the form of... ferritin and hemosiderin
pt has a smooth, shiny red tongue, which indicates... low Hb
petechiae and purpura indicate thrombocytopenia
lightly palpating the lymph nodes and not being able to feel anything... the nurse records... finding as normal
pt test results indicate fibrin split products (FSP)- appropriate nursing action is to monitor for... bleeding
during assessment for anemia, the nurse asks about a history of... stomach surgery
if a pt w/type O Rh+ blood is given AB Rh- blood, the nurse expects... the donor's blood to be lysed
teaching for a bone marrow aspiration includes... pt will experience sharp pain upon aspiration
lymph node biopsy is done to dx neoplastic cells in the lymph nodes

value/belief beliefs/conflict w/tx- blood products or BM transplants
coping & stress tolerance lack of support
plasma clotting factors thrombin converts fibrinogen to fibrin, prothrombin is converted to thrombin, serum ca+ activity as factor IV
platelet plug formation plt interact w/collagen, release of adenosine diphosphate, release of ph3, seratonin & epinephrine, plt agglutination
lysis of clot thrombin catalyzes conversion of plasminogen to plasmin, action of protein C & S,
vascular response vasoconstriction & spasm, damaged vascular surface
increased band neutrophils indicated infection
ESR of 30 mm/hr indicates inflammation of any kind
ptt of 60 seconds can indicate heparin therapy
indirect bilirubin of 2.0 mg/dl indicates hemolysis of RBC
Urine Bence-Jones protein indicates multiple myeloma
what is normal serum iron level? 76-198
what is normal ESR level? 12-23
normal bilirubin levels? 0.2-1.3 mg/dL
Bence Jones proteins are what... small proteins (light chains of immunoblobulin) found in the urine. Testing for these proteins is done to dx & monitor multiple myeloma and other similar diseases. 1st tumor marker for CA.
what are the effects of aging Plts/Total WBC count/ differential NOT affected,cell loss/organ atrophy, dec Hb, iron deficiency anemia, inc MCV, dec MCHC, changes in vascular integrity (bruising)
