Answer 32

yes

Question 33

what is normochromic-normocytic anemia usually from?

Answer 33

secondary anemia to chronic inflamm state or uremia- renal failure, or marrow aplasia,

Question 34

aplastic anemia

Answer 34

bone marrow failure- mno blood cells

Question 35

fanconi's anemia

Answer 35

aplastic anemia, childhood, rare auo recessive, can cause oral cancer, risk of infection

Question 36

in hemolytic anemia you see

Answer 36

decreased hemoglobin- bone marrow can't keep up with what is being lysed

Question 37

immune hemolysis

Answer 37

warm igg reacting anti rbc ag- detect with coombs test

Question 38

mechanical hemolysis

Answer 38

lysis is caused by prosth heart valvue, malignatnt hypertension, disseminated intravstular coag, thrombotic thromccytopenia purpura
