Questions and Answers

1.

This analyte is currently considered the most important value in assessing cardiac risk and directing therapy.
- A.
  
  High-Density Lipoprotein
- B.
  
  Low-Density Lipoprotein
- C.
  
  Troponin I
- D.
  
  Potassium
2.

This is the umbrella medical term for hardening (and narrowing) of the arteries which are caused by several factors, one of these being high blood pressure.
- A.
  
  Atherosclerosis
- B.
  
  Arteriosclerosis
- C.
  
  All of the Above
- D.
  
  None of the Above
3.

LDL can be computed by what equation?
- A.
  
  [ TC - HDL - ( TAG / 5 ) ]
- B.
  
  [ TC - HDL - ( 0.20 x TAG ) ]
- C.
  
  All of the Above
- D.
  
  None of the Above
4.

Choose the incorrect non-enzymatic measurement step for cholesterol : description pair.
- A.
  
  Colorimetry : The absorbance of the colored product (red for the Leibermann-Burchardt Reaction and green for the Salkowski Reaction) is read at 410 nm.
- B.
  
  Extraction : Cholesterol is released from the lipoprotein, thus ensuring no protein interference.
- C.
  
  Saponification : KOH hydrolyzes cholesteryl esters to free cholesterol, thus removing possible colorimetric interference due to the former, because only the latter is to be measured for cholesterol.
- D.
  
  Precipitation : Digitonin is used to ensure no interference from other substances capable of absorbing light at 410 nm, such as bilirubin and hemoglobin.
5.

- C.
  
  Apo A-II
- D.
  
  Apo A-I
6.
