Q

Universal donor?

Type O cause no antigens

18
Q

Hemolytic newborn disease

A

If Rh- mother has Rh+ baby, mother might create anti Rh antibodies

19
Q

What happens if mother creates anti-Rh antibodies

A

second pregnancy, antibodies cross placenta and cause agglutination

20
Q

How blood typing determined

A

Drops of blood mixed in solution with antibodies, clumping occurs

21
Q

Blood typing necessary for?

A

Avoid transfusion reactions

22
Q

Anemia

A

Oxygen carrying capacity of blood reduced

23
Q

Iron deficiency anemia

A

Inadequate absorption, or intake

24
Q

Iron deficiency anemia who’s greatest risk

25
Megaloblastic anemia due to
Inadequate b12 or folic acid
26
Megaloblastic anemia results in
abnormal RBC's, ineffective oxygen transport
27
Pernicious anemia
Type of megaloblastic/unable to absorb b12
28
Hemorrhagic anemia
Excessive RBC loss
29
Acute blood loss
Increase in EPO levels
30
Chronic blood loss
Iron stores deplete, low hemoglobin
31
Hemolytic anemia
premature RBC plasma membrane rupture
32
Thalassemia
Deficient hemoglobin synthesis, RBC's small/short lived
33
Thalassemia most common where
Mediterranean
34
Sickle cell disease
RBC changes shape and ruptures easily
35
Sickle cell disease general facts
Inherited, malaria belt
36
Aplastic Anemia
Destruction of Red bone marrow
37
Leukemia
Bone marrow cancer/ rapid WBC multiplication
38
Hemophilia
easily Bleed with minor traumas, clotting deficiency
39
Hemochromatosis
Body store and absorb too much iron
40
Jaundice
Excessive biliruben in blood, yellow discoloration
