Lc Chemistry The Periodic Table

(MLS ONLY) Increased total serum lactic dehydrogenase (LD) activity, confined to fractions 4 and 5 is most likely to be associated with:
a pulmonary infarction
b hemolytic anemia
c myocardial infarction
d acute viral hepatitis – d acute viral hepatitis
TEST TUBE HOLDER – used for holding test tubes when heating or pouring items.
chemical reaction – Chemical transformation or change; the interaction of chemical entities.
unit analysis – A method of converting between various units of measure.
Scientific theory – A well tested idea that explained and connects a wide range of observations
(MLS ONLY) A 21-year-old man with nausea, vomiting, and jaundice has the following laboratory findings:
Test Patient Reference range
total serum bilirubin 8.5 mg/dl_ (145.4 pmol/L) 0-1.0 mg/dL (0.0-17.1 pmol/L)
conjugated serum bilirubin 6.1 mg/dl_ (104.3 (jmol/L) 0-0.5 mg/dL (0.0-8.6 pmol/L)
urine urobilinogen increased
fecal urobilinogen decreased
urine bilirubin positive
AST 300 U/L 0-50 U/L
alkaline phosphatase 170 U/L 0-150 U/L
These can best be explained as representing:
a unconjugated hyperbilirubinemia, probably due to hemolysis
b unconjugated hyperbilirubinemia, probably due to toxic liver damage
c conjugated hyperbilirubinemia, probably due to biliaty tract disease
d conjugated hyperbilirubinemia, probably due to hepatocellular obstruction – d conjugated hyperbilirubinemia, probably due to hepatocellular obstruction
as the number of covalent bonds between two atoms increases, the distance between the atoms _____, and the strength of the bond between them _____ (increases, decreases) – decreases, increases
Valence electron – an electron in an atom's highest occupied energy level
Isoenzyme assays are performed to improve:
a precision
b accuracy
c sensitivity
d specificity – d specificity
Isotope – An atom with the same number of protons but different mass number (number of neutrons).
The freezing point of water on the Kelvin temperature scale is
2 ways of making Carbon Dioxide – 1: Dilute Acid + Calcium Carbonate = Carbon Dioxide
2: Thermal decomposition of metal carbonates = Carbon Dioxide
Anode – The positive electrode where the non-metal is formed.
Avagadros law – V1 V2
— = —
N1 N2
Solid – A form of matter that has a definite shape and volume.
This is the symbol for Beta radiation
the zero represents that there are no neutrons and protons
the 1- represents a single negatively charged electron
the e represents "electron" – what is this symbol?
What does the 0 represent?
What does the 1- represent?
What does the e represent?
The freezing pоint оf wаter оn the Kelvin temperаture scаle is
metabolism – all the chemical reactions in the body
