Answer #1

Based on the given data, it is due to metabolic alkalosis

First of all see the pH is high (normal 7.35-7.45) so it is alkalosis and the bicarbonate is high ( normal 22-26) so it is a metabolic cause. note that pco2 is normal (normal range 35-45)

So the diagnosis is metabolic alkalosis

The most common conditions that will cause metabolic alkalosis are vomiting, gastric bypass surgery, diuretic drugs, excess antacid intake, aldosterone excess, etc.,.

Hope this helps.... Thank you!!!
