An 18-year-old woman has gastroenteritis with nausea and vomiting and is able to ingest only small amounts of water. After 3 days, she develops light-headedness, especially when sitting or standing. Arterial blood gas analysis is most likely to show which of the following sets of values?
|pH||PCO2 (mm Hg)||HCO3- (mEq/L)|
Correct answer : E
Vomiting causes acid loss. Hence it results in metabollic alkalosis. Respiratory compensation mechanism is activated – CO2 retention is produced (respiratory acidosis).
