- Liver function tests can vary depending on a number of factors, but which of the following would be LEAST likely to occur after obstruction of the common bile duct?:
- elevation of serum conjugated bilirubin
- elevation of serum unconjugated bilirubin
- elevation of serum alkaline phosphatase
- appearance of bilirubin in urine
- decrease of urine urobilinogen
- A patient presents with elevation of unconjugated bilirubin, normal serum alkaline phosphatase, normal “liver” enzyme levels and no bilirubin in the urine. This combination would suggest:
- viral infection of liver
- chemical damage to liver
- increased rate of hemolysis
- obstruction of common bile duct
- all of the above are equally likely
- The BSP function test:
- can distinguish between hepatic and obstructive
liver disease - can distinguish between prehepatic jaundice and
intravascular hemolysis - Is no longer used because of adverse affects to the dye.
- is not effective because BSP is excreted in urine
- can distinguish between viral and alcoholic hepatitis
- can distinguish between hepatic and obstructive
- The following results were obtained on a 73 year old black male:
- alk. phos. = 431 IU/L (ULN = 100)
- acid phos. = 5 IU/L (ULN = 6)
- GT = 13 IU/L (ULN = 29)
Which of the following diseases does this man most likely have?:
- bone disease
- diffuse liver disease
- prostatic cancer
- liver cancer
- renal disease
Use the following KEY to answer Questions 5-8:
- 1, 2, and 3 are correct
- 1 and 3 are correct
- 2 and 4 are correct
- only 4 is correct
- all are correct
- Important function(s) of the liver is/are:
- detoxification of drugs
- conjugation and excretion of bilirubin
- synthesis of albumin
- conservation of bicarbonate
- Liver is involved in which of the following metabolic functions?:
- synthesis of cholesterol
- synthesis of bile acids
- storage of vitamin A
- synthesis of plasma immunoglobulins
- Liver function can be assessed by which of these parameters?:
- blood hemoglobin levels
- serum bile acid concentration
- serum glucose levels
- serum ALT and AST levels
- Fecal urobilinogen levels may be markedly decreased because of:
- hemolysis
- decreased intestinal reabsorption of urobilinogen
- increased serum bilirubin
- biliary obstruction
