Which finding is most characteristic of hepatitis A?

• A. Dark urine
• B. Jaundice
• C. Clay-colored stools
• D. Nausea

Answer: (C)

Hepatitis A causes inflammation of the liver that disrupts bile production and flow into the intestines. Bile pigments that normally reach the gut give stool its brown color; when bile does not reach the intestines effectively, stools lose pigment and become pale or clay-colored. This change in stool color directly reflects impaired bile excretion from hepatocellular injury, making clay-colored stools a characteristic finding. Jaundice and dark urine are common in liver disease but are less specific, and nausea is nonspecific. So the pale stool color best reflects the hepatobiliary impact of hepatitis A.
