  1. What is a blank tube used for when using a spectrophotometer? The answer is (b): It is used to QC the reagents. Explanation: a. Incorrect - The blank tube does not give the color intensity at a known concentration; it is used to set the baseline. b. Correct - The blank tube is used to QC (quality control) the reagents by setting a baseline measurement. c. Incorrect - The blank tube is not used to measure the color of the reagent; it is used to zero the spectrophotometer. d. Incorrect - Not all of the above are correct.

  2. In what major organ of the body is the majority of the body's cholesterol synthesized? The answer is (d): Liver. Explanation: a. Incorrect - The heart does not synthesize cholesterol. b. Incorrect - The pancreas is not the primary site for cholesterol synthesis. c. Incorrect - The gallbladder stores bile but does not synthesize cholesterol. d. Correct - The liver is the major organ where the majority of the body's cholesterol is synthesized.

  3. Which of the following tests is used to diagnose gout? The answer is (b): Uric acid. Explanation: a. Incorrect - Bilirubin is related to liver function and jaundice, not gout. b. Correct - Uric acid levels are measured to diagnose gout, as elevated levels can lead to the formation of urate crystals in joints. c. Incorrect - CRP (C-reactive protein) is a marker of inflammation but is not specific for gout. d. Incorrect - Not all of the above are correct.

Summary: 7. The answer is (b): It is used to QC the reagents. 8. The answer is (d): Liver. 9. The answer is (b): Uric acid.
