Final answer:
Metabolic alkalosis is diagnosed by a higher-than-normal pH and elevated bicarbonate levels in the blood. The consistent diagnostic finding for this condition is High TCO₂ and increased HCO₃ levels.
Step-by-step explanation:
Metabolic alkalosis is characterized by a higher-than-normal pH and elevated bicarbonate levels in the blood. The correct option consistent with the diagnosis is a. High TCO₂, increased HCO₃. In metabolic alkalosis, the total CO₂ (TCO₂) levels are high, indicating an excess of bicarbonate, and the HCO₃ levels are increased as well. This imbalance can be caused by factors such as excessive ingestion of bicarbonate or antacids, Cushing's disease, and loss of hydrochloric acid from the stomach through vomiting, among others.
