a 42 - year - old female presents with gallstones blocking her bile duct. which of the following is most likely to be elevated in her blood?
a) urobilinogen
b) conjugated bilirubin
c) unconjugated bilirubin
d) rbcs

Explanation:

When gallstones block the bile duct, conjugated bilirubin (which is produced in the liver and is water - soluble) cannot be excreted into the intestines. Instead, it backs up into the bloodstream. Urobilinogen is formed from the reduction of bilirubin in the intestines and would be decreased in this case (due to less bilirubin reaching the intestines). Unconjugated bilirubin is bound to albumin and is not directly affected by a bile duct blockage in the same way as conjugated bilirubin. RBCs (red blood cells) are not typically elevated due to a bile duct blockage caused by gallstones.

Answer:

B. Conjugated bilirubin
