Final answer:
To find out the cause of metabolic alkalosis, diagnostic lab tests for pH, CO2 partial pressure (pCO2), and HCO3 can be performed. These tests help identify if the alkalosis is metabolic or respiratory and the extent of compensation. Prolonged vomiting, diuretic use, antacid overuse, and certain diseases can contribute to metabolic alkalosis.
Step-by-step explanation:
To find out why someone has metabolic alkalosis, diagnostic lab tests for pH, CO2 partial pressure (pCO2), and HCO3 can be performed. These tests can identify whether the alkalosis is metabolic or respiratory and the extent to which compensatory mechanisms are working.
The blood pH value, pCO2, and HCO3 values aid in determining the cause and classification of the alkalosis. Conditions such as prolonged vomiting, diuretic use, antacid overuse, and certain diseases like Cushing's disease can contribute to metabolic alkalosis.
