Question Of The Day: Gastrointestinal Disorders
Q. A nurse is caring for a client with cholelithiasis. Which sign indicates obstructive jaundice?

A. Straw-colored urine
B. Reduced hematocrit
C. Clay-colored stools
D. Elevated urobilinogen in the urine

Correct Answer: C


Explanation: Obstructive jaundice develops when a stone obstructs the flow of bile in the common bile duct. When the flow of bile to the duodenum is blocked, the lack of bile pigments results in a clay-colored stool. In obstructive jaundice, urine tends to be dark amber (not straw-colored) as a result of soluble bilirubin in the urine. Hematocrit levels aren't affected by obstructive jaundice. Because obstructive jaundice prevents bilirubin from reaching the intestine (where it's converted to urobilinogen), the urine contains no urobilinogen.
