Jaundice is best described as which clinical sign?

• A. Yellowing of the skin and sclera due to bilirubin accumulation
• B. Pale skin and mucous membranes
• C. Redness of eyes
• D. Yellow stool due to pancreatic disease

Answer: (A)

Jaundice is yellow discoloration of the skin and sclera caused by bilirubin buildup. Bilirubin comes from the breakdown of heme in red blood cells and is normally processed by the liver and excreted in bile. When bilirubin accumulates—due to increased production, impaired liver conjugation, or biliary obstruction—the pigment deposits in tissues, producing the yellow tint seen in the eyes and skin. This sign points to potential liver dysfunction, biliary blockage, or hemolysis.

Pale skin and mucous membranes indicate pallor from anemia, redness of the eyes suggests irritation or conjunctival injection, and yellow stool related to pancreatic disease reflects different GI processes rather than jaundice itself.
