Practice And Sections Flashcards
Total volume of blood
5-6L
Percentage of blood in our body weight
7-8%
Color of deoxygenated blood
Dark red
Color of oxygenated blood
Bright red
Contributes to color of blood
Hemoglobin/Iron
Plasma
95%water, 5%solute(enzymes, vitamins, electrolytes, hormones, proteins, CHO)
Cellular component
45%solid portion(wbc, rbc, platelets)
Factor 1
Fibrinogen
Responsible for clotting
Fibrin
Liquid portion of coagulated blood
Serum
Liquid portion of uncoagulated blood
Plasma
Performed by RT and RN
Arterial puncture
Collection of blood from vein
Venipuncture
Principle of tourniquet
18-20inches long, 1inch wide, 3-4inches above the puncture site, not longer than 1min
Used to collect blood for a legal blood alcohol level(ethanol testing)
Benzalkonium Chloride Solution(zephiran chloride)
Most common site for venipuncture
Antecubital Fossa
Anatomical patterns of veins
H pattern, M pattern
Destruction of RBC, resulting in release of hemoglobin and cellular contents into the plasma
Hemolysis
Common and normal gauge
19-22cc
Analytes are normally present in greater amounts in RBC than plasma
False increase(alanine aminotransferase, creatinine kinase, potassium)
Analytes present in greater amounts in plasma than RBC
False decrease(sodium, chloride)
Color interference
False increase(hemoglobin, protein, bilirubin)
RBC constituents can react with analytes
False decrease(CO2, thyroxin, insulin)
Increased turbidity
False increase(protein)
