Choose the significant change in arterial blood gases expected with prolonged severe vomiting:

Question

Quizplus · Accepted Answer

Prolonged severe vomiting leads to loss of gastric acid and chloride ions, resulting in decreased PCO2 and chloride levels. Additionally, the loss of hydrogen ions leads to increased bicarbonate reabsorption, resulting in a compensatory decrease in bicarbonate ion levels. This metabolic acidosis leads to a decrease in serum pH, which is expected to be around 7.35. Therefore, the best choice is B, decreased bicarbonate ion, decreased PCO2, serum pH 7.35.
