Welcome to your 🦠 Viral Hepatitis A, B & C Arena
1.

5.
A patient with chronic hepatitis B is started on tenofovir. What is the principal antiviral mechanism of this drug?
6.
A patient receiving an HCV treatment regimen that includes ribavirin develops fatigue, pallor and a falling hemoglobin concentration. Which adverse effect is most likely?
7.
A district hepatitis programme screens 10,000 residents during one month and determines the proportion currently living with chronic hepatitis B. Which epidemiological measure is being estimated?
8.
Which statement best describes modern treatment of chronic hepatitis C?
9.
A 46-year-old patient has persistent HCV RNA and mildly elevated aminotransferases. Liver biopsy shows chronic portal inflammation with interface activity. Which additional histological feature would support the same underlying disease?
10.
A liver biopsy from a patient with chronic hepatitis B shows hepatocytes with finely granular eosinophilic cytoplasm. Which finding is being described?
11.
A patient with acute viral hepatitis has markedly raised serum ALT and AST levels. What is the main reason for this biochemical abnormality?
12.
A 27-year-old patient with acute viral hepatitis is being managed in family practice. Over the next day, vomiting becomes persistent, oral fluids cannot be retained and jaundice is worsening. Mental status remains normal. What is the most appropriate next step?
13.
A patient with acute hepatitis B has substantial hepatocellular injury even though HBV itself is not strongly cytopathic. Which mechanism is primarily responsible for the liver damage?
14.
Which finding most strongly supports chronic hepatitis B rather than acute hepatitis B?
15.
A 41-year-old man with chronic hepatitis B has persistently elevated ALT, a high HBV DNA level and evidence of significant hepatic fibrosis. He has no features of decompensated cirrhosis. Which management principle is most appropriate?
16.
A medical student compares treatment duration for chronic hepatitis B. One patient receives entecavir, while another selected patient receives pegylated interferon. Which statement best describes the difference?
17.
A patient with long-standing hepatitis B undergoes liver biopsy. Portal inflammation extends into adjacent hepatocytes, and fibrous septa connect portal and central regions. Which consequence is most directly suggested by the fibrous change?
18.
Which drug class used in hepatitis C treatment includes agents such as velpatasvir and ledipasvir?
19.
A child with uncomplicated acute hepatitis A is clinically stable and able to tolerate oral intake. What is the most appropriate management?
20.
A 48-year-old patient with chronic hepatitis B has ascites and other features of decompensated cirrhosis. The treatment options being reviewed include pegylated interferon and oral nucleos(t)ide analogues. Which principle is most appropriate?
21.
A patient recovering from natural hepatitis B infection is most likely to have which serological pattern?
22.
A 52-year-old man with chronic hepatitis B develops splenomegaly, thrombocytopenia and esophageal varices. Which pathological process most directly explains these findings?
23.
A patient receiving pegylated interferon for chronic hepatitis B develops fatigue and low blood counts. Which adverse effect best explains this finding?
24.
A patient with chronic hepatitis C has advanced decompensated liver disease. A treatment regimen containing an HCV protease inhibitor is being considered. Which principle is most appropriate?
25.
A patient has positive anti-HCV antibodies on screening. Which investigation best confirms current active hepatitis C infection?
26.
Which serological marker is most useful for identifying recent acute hepatitis B infection?
27.
A patient with chronic hepatitis C is prescribed a regimen containing glecaprevir. The drug interferes with processing of viral proteins required for replication. Which molecular target best explains this action?
28.
A 58-year-old man with chronic hepatitis C and established cirrhosis completes direct-acting antiviral therapy. HCV RNA remains undetectable after treatment. Which follow-up principle is most appropriate?
29.
Which public-health measure most directly reduces transmission of hepatitis C in healthcare settings?
30.
A 39-year-old woman with chronic hepatitis B has HBsAg positivity, absent HBeAg and detectable anti-HBe. Despite this, ALT is persistently raised and HBV DNA is high. Which interpretation best explains this pattern?
31.
Which pathological feature is classically associated with chronic hepatitis C?
32.
A patient with chronic viral hepatitis develops ascites and a recent episode of hematemesis. What is the most appropriate next step in family practice?
33.
Which measure is most specific for preventing hepatitis B infection at population level?
34.
A patient receiving tenofovir disoproxil for chronic hepatitis B develops a progressive increase in serum creatinine during follow-up. Which drug-related problem should be considered first?
35.
A 24-year-old man with acute viral hepatitis undergoes liver biopsy because of an atypical clinical course. Scattered shrunken hepatocytes with intensely eosinophilic cytoplasm and condensed nuclei are seen within the lobules. Which process best explains these cells?
36.
A patient with chronic hepatitis B is followed over several months. HBeAg becomes undetectable, anti-HBe appears, HBV DNA falls substantially and ALT approaches normal. Which change has most likely occurred?
37.
Which hepatitis virus is most likely to produce severe acute disease in a pregnant woman?
38.
An 8-year-old child develops anorexia, vomiting, dark urine and jaundice two weeks after several family members experienced a similar illness. ALT is markedly elevated. Serology shows IgM antibody against hepatitis A virus. Which interpretation is most appropriate?
39.
A 9-year-old child develops fever, anorexia, nausea, dark urine and jaundice after consuming food from a contaminated source. Which route of transmission is most consistent with the likely infection?
40.
A healthcare worker has completed hepatitis B vaccination and has never been infected with HBV. Which serological pattern is most likely?
