INCOMPLETE Cardiovascular (Si) Flashcards
ANEMIA
lower than normal count of RBC
Anemia: DX Tests
- CBC
- Erythrocyte Indices
- Peripheral Smear
- Schilling Test/Megaloblastic Anemia Profile
- Gastric Analysis
- Radiologic Studies (MRI, CT)
- Bone Marrow Aspiration/Biopsy
- Lymphangiography
CBC
- routine screening, provides info on hematologic and other organ systems
- info on RBC, Hgb, Hct, Erythrocytes, Platelets, WBC (differential)
Erythrocyte Indices
provides info on SIZE, WEIGHT. Helps to categorize ANEMIAS
- Size (MCV) = Mean Corpuscular Volume
- Weight (MCH) = Mean Corpuscular Hemoglobin
- Hgb Conc (MCHC) = Mea Corpuscular Hgb conc.
Erythrocyte Indices: MCV
MCV (size): Mean Corpuscular Volume, measures average volume, SIZE of 1 RBC, HCT/RBC
normal: adult/elderly/child 80-95mm
Erythrocyte Indices: MCH
MCH (weight): Mean Corpuscular Hemoglobin,
measures average AMT of Hgb in 1 RBC, Hgb/RBC
normal: adult/elderly/child 27-31pg
Erythrocyte Indices: MCHC
MCHC (Hgb Conc): Mean Corpuscular Hgb conc, measures avg concen or % of Hgb in 1 RBC, Hgb/HCT
normal: adult/elderly/child 32 - 36g/dl or 32 - 36%
Normocytic, Normochromic, Anemia
SEE SLIDE
Peripheral Smear
Used to differentiate anemias and blood dyscrasias
- 1 drop blood on slide, under microscope
- NO FASTING required
- Examines RBC, WBC, PLTs
- size, shape, color, intracellular content
Schilling Test
*NOT FOR PREGN or BRST FEEDing (d/t radiactive B12)
-to Dx Pernicious Anemia
-ingest radioactive B12 PO, then urine in 1-2hrs,
-Normal: excretion 10-40%
-Abnormal: little to zero (indicates body is not absorbing B12 which is why nothing is being excreted by kidneys in urine)
-lack of intrinsic factor = no B12 absorbtion
(sx removing stomach etc, Intrinsic Factor made in stomach)
Megaloblastic Anemia Profile
- REPLACES Schilling Test
- blood test to measure 4 compounds. If all 4 compounds UP then = Vit B12 LO
Gastric Analysis
- rarely used (too invasive)
- to detect peptic ulcer disease and Pernicious Anemia
- NPO after midnight
- insert GTube
- Aspirate q15min for 90min to test fluid
Development of Blood Cells
SEE SLIDE pg
Mnemonic:
Grandpa Ben eats little monkeys
(Granulocytes, (BEN:Basophyls, Eonocytes, Nutrophil), Lymphocytes, Monocytes
WBC mnemonic
Never Let Monkeys Eat Bananas
- types of white blood cells, from most to least numerous, in the blood.
- *Neutrophil, Lymphocyte, Monocyte, Eosinophil, Basophil**
Bone Marrow Exam
- Biopsy and Aspiration (2 steps)
- to confirm Diff blood dyscrasias
- from soft spongy tissue in bones (sternum, ribs, pelvis, femur, tibia, humerous
