Q

Erythrocytes index

Aid in describing anemias

A

MCV- (RBC size) increase w/ pernicious anemia and folic acid

MCHC-(hemoglobin saturation) decrease in iron deficiency anemia, thalassemia and hypochromic anemia

MCH-(RBC weight) increase macrocyclic anemia, decrease hypochromic anemia

Q

Serum iron (IBC)

A

Helpful to classify anemias, differentiating acute from chronic disorders.
Increase= RBC destruction
Decrease=iron deficiency anemia

24
Q

Total iron binding capacity (TIBC)

A

Measures amount transferin can combine with
Transferin- plasma protein responsible for iron transportation to bone marrow for purpose of Hgb synthesis

Decreased=sickle cell anemia, hemolytic anemia
Increase=acute disorder

25
Serum bilirubin
Formed from break down of hgb carried in plasma to liver
26
Serum bilirubin | Conjugated
Direct reacting( soluble) increased= obstructive jaundice, liver cancer,wilsons disease,accumulation of copper in brain, liver, kidney,cornea. Something wrong with liver break down RBC
27
Serum bilirubin | Unconjucated
Indirect reacting(protein bound) increased= sickle cell anemia,transfusion reaction,hemolytic anemia, pernicious anemia Protein with blood break down RBC
28
Used to diagnose pernicious anemia.
Schilling test
29
Schilling test procedure
``` 24 hour urine collection Oral radioactive b12 administered Non radioactive 2 hr later No b12 3 days before test Laxative 24 h before test NPO 8-12 hours before ```
30
VIT. B12 essential for
RBC maturation
31
VIT. B12 is important for
Normal hemotopoiesis
32
The extrinsic factor of VIT. B12 is obtained from ____ and is _____ in the small intestines when intrinsic is present
Food | Absorbed
33
VIT. B12 intrinsic factor is produced by
Gastric mucosa
34
When intrinsic factor is missing
Pernicious anemia develops
35
Decreased VIT. B12 level
Pernicious anemia, Mel absorption syndrome
36
Increased VIT. B12 level
Acute/ chronic myelscytic leukemia, hepatitis
37
Serum folate level ( folic acid B9)
Needed for normal RBC and WBC formation useful for classifying anemias
38
Decreased level of folic acid
VIT. B6 anemia, folic acid anemia
39
Elevated folic acid levels
Pernicious anemia
40
Foods high in iron
* Beef liver * Blackstrap molasses * Chicken liver * Cooked oatmeal * Cooked prunes * Cooked shrimp * Dried apricots * Egg yolks * Kidney beans * Lean beef * Lima beans * Whole grains * Prune juice * Raisins * Spinach and green leafy vegetables * Turkey
41
Foods high in folic acid
``` Asparagus • Beef • Fish • Cabbage • Brussels sprouts • Broccoli • Legumes (kidney beans, etc.) • Liver • Eggs • Whole grains ```
42
Ng tube inserted- histamine injected to stimulate gastric secretions, gastric contents aspirated and analyzed
Gastric analysis
43
Achlorhydria ( absence of hc1)
Pernicious anemia
44
Sickledex test
Abnormal hgb causes RBC to form crescents or sickle shape. With adequate hgb and RBC maintain normal shape Sickling of cells in hypoxia suggest sickle cell trait or anemia
45
WBC count
4,500-11,000 Determine # of leukocyte Aid in diagnosis of infection and blood disorders such as leukemia
46
Determine type of infection, take before given antibiotics
Blood culture and sensitivity
47
WBC differential | Granular
Produced in red bone marrow Neutrophils- go directly to infection Eosinophils- got to pericites and pinworms Basophils- increase allergic reaction, release histamine
48
WBC differential | Agranular
Produced in lymphatic tissue of spleen, lymph nodes, thymus, and red bone marrow Lymphocytes Monocytes
49
Two types of lymphocytes
T cells | B cell
50
Decreased neutrophils
Leukemia | Iron deficiency anemias
51
Decreased monocytes
Lymphocytic leukemia | Aplastic anemia
52
Decreased lymphocytes
Cancer Leukemia Aplastic anemia
53
Increased neutrophils
Acute infection | Hodgkin disease
54
Increased basophils and monocytes
Leukemia
55
Increased lymphocytes
Lymphatic leukemia Chronic infection, Hodgkin disease
