- AVerdadero
- BFalso
2Which of the following best describes the cause of the colour change seen in jaundice patients.

- BHyperbiliruinaemia
- CBilirubin getting trapped in the skin and not metabolised.
3Bilirubin is derived from tetrapyrole prosthetic group found in lymphocytes.
- AVerdadero
- BFalso
4Which of the following are the 3 main causes of why bilirubin levels may rise in blood?
- AHaemolysis of red blood cells.
- BBilirubin in prescription medications.
- CFailure of the conjugating mechanism.
- DObstruction in the biliary system.
5Increased bilirubin production as a result of haemolysis gives...
- A...a predominantly unconjugated hyperbilirubinaemia.
- B...a predominantly unconjugated hypobilirubinaemia.
- C...a predominantly conjugated hyperbilirubinaemia.

- A>200 microlitres per litre.
- B>40 microlitres per litre.
- C>300 microlitres per litre.
- D>100 millilitres per litre.
7Which of the following best describes the effect of a complete blockage of the bile duct by a gallstone?
- ABilirubin and alkaline phosphatae are raised. Little or no urobilinogen in the urine and the stools will be pale.
- BBilirubin is raised and hence, the stools are dark.
- CBilirubin urobilinogen are raised, with pale stools and urine.
8Bilirubin is partly digested by gut bacteria to produce stercobilinogen - this is partly reabsorbed and re-excreted in the urine as urobilinogen.
- AVerdadero
