Verified step by step guidance

Understand the concept of metabolic alkalosis: It is a condition characterized by an elevated pH in the blood due to increased bicarbonate (HCO3-) levels or a loss of hydrogen ions.

Identify the normal ranges for arterial blood gases: Normal pH is 7.35-7.45, normal HCO3- is 22-26 mEq/L, and normal PaCO2 is 35-45 mmHg.

Determine the pH level that indicates alkalosis: A pH greater than 7.45 suggests alkalosis.

Look for elevated HCO3- levels: In metabolic alkalosis, the HCO3- level is typically higher than the normal range of 22-26 mEq/L.

Review the provided options and identify the one with a pH greater than 7.45 and an elevated HCO3- level, which would be consistent with metabolic alkalosis.
