A woman with a history of severe diarrhea has the following arterial blood values:
pH: 7.25
PCo2: 24 mmHg
HCo3-: 10 mEg/l
venous blood samples show decreased blood K+ and a normal anion gap.
the correct diagnosis for this patient is
A woman with a history of severe diarrhea has the following arterial blood values:
pH: 7.25
PCo2: 24 mmHg
HCo3-: 10 mEg/l
venous blood samples show decreased blood K+ and a normal anion gap.
The decreased blood K+ is a result of
