Final answer:
The correct answer related to post-hepatic jaundice is pruritic skin and light-colored stools, which occur due to bile duct obstruction preventing normal excretion of conjugated bilirubin.
Step-by-step explanation:
Post-Hepatic Jaundice Symptoms
Post-hepatic jaundice, also known as obstructive jaundice, is usually caused by blockages in the bile ducts, which prevent the normal excretion of conjugated bilirubin. As a result of the obstruction, conjugated bilirubin builds up in the blood and can lead to certain symptoms. Among the options provided:
- Pruritic skin and light-colored stools are indicative of post-hepatic jaundice. Pruritus or itching arises due to the bile acids in the bloodstream, and stools become light-colored due to a reduction in excretion of bile pigments into the digestive tract.
- Dark-colored urine can occur due to increased levels of conjugated bilirubin being excreted through the kidneys.
- Increased serum levels of unconjugated bilirubin are more related to pre-hepatic or hemolytic jaundice, not post-hepatic jaundice.
- The loss of all metabolic functions is not specific to post-hepatic jaundice and is an extreme situation more likely associated with acute liver failure.
For the question at hand, the correct answer related to post-hepatic jaundice is a. pruritic skin and light-colored stools.
