If there is more than one problem in her blood work results, is there a relationship among those factors?

Explanation / Answer

What appears to be Mary’s problem(s), from the results of herblood work?

Mary has low pH, pCO2 and HCO3 and pO2 is high. All the other parameters are normal.

Low pH, pCO2 and HCO3 indicate metabolic acidosis.

What sort of change has occurred in her acid-base balance?

Looking at the pH, we can say that the pH is lesser than the normal range. When the pH reduces the blood become more acidic.

If there is more than one problem in her blood work results, is there a relationship among those factors?

There are more than one problem in her blood work. As said before, Mary's blood has low pH, pCO2 and HCO3 and high pO2. Loe pCO2 and high pO2 indicate that the concentration of CO2 is very low while concentration of O2 is high in her blood. Low CO2 leads to low HCO3. High O2 leads to high carbonic acid. As the concentration of HCO3 is very low, it is insufficient to equilibriate the level of carbonic acid. So the excess carbonic acid results in more acidic condition.
