A patient with a viral illness and severe vomiting has an elevated
CO2 level and pH of 7.53. She is breathing slowly. What condition
does she have? - ANSWER-Metabolic alkalosis
The patient's pH and CO2 levels are both elevated (moving in the
same direction). This indicates metabolic alkalosis. The CO2 level
is high because her respiratory system is attempting to
compensate for the high pH by exhaling less and retaining more
CO2.

His K+ is elevated because, as H+ moves inside of cells in an
attempt to get it out of the bloodstream, K+ moves from cells into
the bloodstream. - ANSWER-His CO2 level is increased because
