1. Which statement best describes the classification of liver disorders:

anatomic variants provide definitive diagnosis

classification is obscure because the etiology and pathogenic mechanisms are not clearly defined.

diffuse parenchymal disease shows more specific imaging findings than focal disease

thrombosis is not identified with present imaging technology

2. . Parenchymal disease includes all except:

hepatitis

cirrhosis

cholangitis

focal disease


3. Parenchymal disease refers to:

dysfunction of hepatocytes

normal function of hepatocytes

decreased levels of liver enzymes

increased protein synthesis


4. In the spectrum of hepatitis, the virus with the worst prognosis is:

hepatitis A

hepatitis B

hepatitis C

Delta agent


5. The virus that is found in greatest concentration in the liver and less in the blood is:

hepatitis A

hepatitis B

hepatitis C

Delta agent


6. Clinical features of acute viral hepatitis include all except:

loss of appetite

weakness

jaundice

headache


7. Laboratory values that may be helpful to evaluate in acute hepatitis include all except:

lactic dehydrogenase

transaminase

alkaline phosphatase

bilirubin


8. If untreated, acute hepatitis may develop into chronic hepatitis after:

two months

three months

six months

eight months


9. Patients with chronic active hepatitis usually have hepatocellular necrosis and fibrosis that progresses into:

chronic persistant hepatitis

cirrhosis

fatty liver

thrombosis of the portal vein


10. Liver function tests may do all the following except:

improve the detection of hepatobiliary abnormalities

determine the severity of hepatic disease

classify the type of hepatic disease

differentiate the basis for clinically suspected disease


11. The prediction of the severity of hepatocellular disease is best determined by:

prothrombin time

bilirubin

transaminase

alkaline phosphatase


12. This laboratory value increases markedly in diseases that impair bile formation and to a lesser extent in hepatocellular disease.

bilirubin

alkaline phosphatase

serum albumin

alphafetoprotein


13. The imaging procedure that is utilized to determine the functional uptake of the liver is:

ultrasound

radionuclide scanning

magnetic resonance imaging

endoscopic retrograde cholangiopancretography


14. The primary modality for evaluating cholestasis and differentiating extrahepatic from intrahepatic causes of jaundice is:

ultrasound

radionuclide scanning

computed tomography

plain radiograph


15. The most prominent sonographic finding in a patient with hepatitis is:

uniformal increased echogenicity

diffuse focal lesions throughout the hepatic parenchyma

increased visualization of the portal triad

hypo to isoechoic texture throughout the liver parenchyma


16. Chronic cirrhosis is best defined by sonography when:

surface nodularity and ascites is seen

no change of the liver parenchyma pattern is identified

vascularity of the liver markings are increased

reversed flow is identified in the inferior vena cava


17. The liver is unique in that it has the ability to:

repair itself without medical intervention

regenerate itself

rejuvenate itself with altered vitamin intake

replace damaged cells if the infection is uncontrolled


18. Which statement is not true regarding treatment options for severe hepatic disease:

a liver biopsy with mild inflammation without fibrosis is an indication progression to severe liver is unlikely

once fibrosis is found, cirrhosis will occur regardless

a combination of interferon and ribavarin may be used to control the progression of the disease

intensive medical treatment will control the disease in all patients

19. Hepatocellular carcinoma is different from cholangiocarcinoma in that:

HCC involves the vascular structures of the liver

Cholangiocarcinoma invoves the parenchymal hepatocytes

HCC is found in the cords, ducts, and parenchymal hepatocytes

HCC is found in the bile duct epithelium


20. Which statement is not true regarding HCC:

the tumor may invade the biliary tree, hepatic veins, or portal veins

a high percentage of patients may have portal vein thrombosis

the tumor may destroy the portal venous radicle walls and invade the lumen

vascular invasion indicates inoperability
