How does an intestinal obstruction at the pylorus or high in the small intestine cause metabolic alkalosis?
A) By the gain of bicarbonate from pancreatic secretions that cannot be absorbed
B) By an excessive loss of hydrogen ions normally absorbed from gastric juice
C) By an excessive loss of potassium promoting atony of the intestinal wall
D) By the loss of bile acid secretions that cannot be absorbed

Question

Quizplus · Accepted Answer

An intestinal obstruction at the pylorus or high in the small intestine can cause metabolic alkalosis because gastric juice, which normally contains hydrogen ions, is not able to be absorbed due to the obstruction. This leads to an excessive loss of hydrogen ions, resulting in an increase in pH and ultimately metabolic alkalosis.
