Red blood cells are called
erythrocytes
White Blood cells are called
leukocytes
plateletes are called
thrombocytes
2 types of thalassemia are
alpha thalassemia
beta thalassemia
alpha thalassemia is…
issues with synthesis of alpha chain on Hgb
beta thalassemia is…
issues with synthesis of beta chain of Hgb
beta minor thalassemia is…
mild microcytic anemia
microcytic anemia is…
something effects bone marrows ability to create new RBCs; TX not necessary
beta intermedia needs…
child requires blood transfusions to maintain quality of life
what is thalassemia…
inherited trait where body does not produce enough Hgb
beta major needs…
ongoing medical attention, blood transfusions, chelation therapy
chelation therapy is…
iron reducing therapy (chelators bind to iron and transport out of body)
Idiopathic Thrombocytopenia Purpura…
immune response following infection where body produces antiplatelet antibodies, destroying body’s platelets
S/S of ITP
petechiae
purpura
bruising
petechiae
pinpoint red/cola colored rash d/t superficial hemorrhaging; NON BLANCHABLE
purpura
purple/ecchymotic; large areas of hemmorhage underneath the skin d/t leaking of blood vessels
TX of ITP
corticosteroids or IgG (IgG given only if life threatening)
what is IgG
Immunoglobulin G - most common type of antibody formed by B cells
Henoch-Schonlein Purpura

Henoch Schonlein Purpura TX
anticoags
Monitor Na levels –> can lead to HTN
IV therapy
corticosteroids (prednisone)
platelets
Analgesics
DIC stands for
Disseminated Intervascular Coagulation
DIC is…
activation of coagulation where thrombin is generated, fibrin id deposited, platelets are consumed
Causes of DIC
endotoxins
septic shock
necrotic tissue
injury
DIC S/S
hematuria
blood in stool
blood at IV site, mouth, wound
epistaxis
blood from umbilical cord (newborn)
DIC TX
low dose heparin
surgical intervention to find bleed
Why is heparin used to treat DIC?
heparin reduces consumption of platelets
Hemophilia A is…
Factor VIII deficiency –> bleeding into joints
Hemophilia A S/S
joint pain/swelling
epistaxis
bruising
Hemophilia A TX:
administer factor VIII supplement as prescribed
If bleeding in joint - apply ice
if bleeding in spine - apply pressure
Desmopressin
Desmopressin
Antidiuretic; synthetic form of vasopressin
vasoconstriction, fluid retention
increases BP
