Pretest Pediatrics- Excess pH Q

[Dawkter]

In pretest pediatrics the concept of excess ph is mentioned in questions 228 through 234. I am having a tough time understanding what exactly this means in distinguishing between a metabolic acidosis and alkalosis. Anyone able to explain this concept and how to approach these questions? Thanks!

Sorry to bump this but I'm struggling with the same issue. Anyone understand what is meant by the "Excess pH" notation in Pediatrics pretest? The answer explanation seems to contradict what most sources online define as "Base Excess" which I assumed to be the same thing.


EDIT: To create a context, the questions give us a set of values: Base pH, PCO2, PO2, and Excess pH. Based on the answer explanations, it seems that the higher the Excess pH, the more (metabolic) acidotic of a state the patient is in.
