Test 2 Flashcards
Process of blood cell production.
Haematopoeisis
Most abundent protein in the blood.
albumin
What is hematostasis?
stoppage of blood
And product of homeostasis/ coagulation/ clotting factor.
Fibrin
Pt with H?O hepatitis have deficiency of clotting factor because liver is responsible for producing…
procoagulant prothrombin and fibrinogen
What can prevent blood clotting.
active fibrinolysis
What binds and cleaves plasminogen to make plasmin?
Streotokinase (bacterial orgin)
Excessive clotting due to increase thrombocyte is called…
thrombocythemia
In vitamin B12 and Folic acid deficiency what will be the change in HgB?
Normal HgB content (chromic to normal)
In vitamin B12 and Folic acid deficiency ; note what about rbc size
cytic change will be occuring as it b12 and folic acid need for maturation, so only cystic change will occur and chromic will be normal, RBC will be macrocytic-megaloblastc anemia)
Woman came to the ER with signs and syymtoms of yellowish pale skin which is suggestive of which type of anemia.
Hemolytic anemia
82 year old woman dx with polycythemia. What are the signs and symptoms?
- plethora (overabundance)
aquagenic pruritus
What is aquagenic pruritus?
severe itching with contact to water
What is the significance of sickle cell anemia?
Deoxygenated abnormal HgB (HbS) crystallized and damage the endothelial wall of blood vessels and cause blood vessel occlusion
Abnormality of α OR β globin biosynthesis is called..
thalassemia
Which one is not a normal tissue change?
Leukopenia
Leukopenia
reduction in white blood cells
What is the clinical manifestation of leukopenia?
C/F (ulceration of mucous membrane)Note- infection, fever, septicemia (rare), may lead to ulcer- particularly around the mouth, airways, colon and skin; diarrhea, malaise/fatigue/weakness, tachycardia)
What is leukopenia typically treated with?
hematopoietic growth factor
What is leukocytosis?
abnormal increase in leukocytes (>11000/μl)
Granulocytosis occurs in.
( increased neutrophils - Bacterial infection, eosinophil’s, basophils – microbial invasion
Eosinophilia occurs in.
hypersensativity reactions and parasitic infection (increased number of eosinophils)
Monocytosis occurs when…
(increased number of monocytes in the blood) prolonged infection where most of the neutrophils have died
Lymphocytosis occurs with…
(increased lymphocytes) viral infections
What is the most common cause if infectious mononucleosis (MONO)
EPSTEIN BAR VIRUS (EBV) (cause acute infection of B lymphocyte)
In which Leukemia mostly immature lymphocyte undifferentiated cell(B cell) present
Acute lymphocytic leukaemia (ALL)
What is the most common cancer in children?
acute lymphocytic leukaemia
In which Leukemia mostly mature lymphocyte B cell is affected
chronic lymphocytic leukemia (CLL)
What is the most common cancer in north america
chronic lymphocytic leukemia (CLL)
What is the term of excess # of circulating thrombocytes?
Thrombocytosis (>400,000⁄μl)
What is the term for a decrease in the # of circulating platelets?
thrombocytopenia (<100 000/μl)
What is the term for microvascular thrombosis (increased thrombosis occurs)?
thrombocythemia or thrombocytosis
Signs and symptoms of thrombocythemia.
warm, red extremities with itchy sensation more common on toes and fingers
In hepatitis liver dysfunction which clotting factor will be absent.
Prothrombin and Fibrinogen
A genetic bleeding disorder.
hemophilia
