A client with cholelithiasis has a gallstone lodged in the common bile duct. Which finding would you expect as an early sign of this obstruction?

• A. Circumoral pallor
• B. Light amber urine
• C. Black, tarry stools
• D. Yellow sclerae

Answer: (D)

Blockage of the common bile duct prevents bile and conjugated bilirubin from reaching the intestine, causing the bilirubin to build up in the blood and produce jaundice. The earliest clinical sign you’d notice is yellowing of the sclera (scleral icterus) because the eyes are a prominent, early indicator of bilirubin in the bloodstream. This reflects obstructive jaundice from a stone blocking bile flow. As obstruction progresses, urine often becomes darker due to bilirubin excretion in the urine, and stools may become pale because bile pigments aren’t reaching the gut. The other signs listed don’t fit the pattern: circumoral pallor isn’t a typical early sign of biliary obstruction; light amber urine would not align with the expected dark urine from bilirubin in the urine; black, tarry stools point to GI bleeding rather than biliary obstruction.
