Final answer:
The given values indicate an imbalance in the blood's acid-base balance, specifically metabolic alkalosis. The pH value is elevated, indicating alkalosis, while the PaCO2 value is normal. The elevated HCO3- value points to a metabolic imbalance.
Step-by-step explanation:
The given values indicate an imbalance in the acid-base balance of the blood. The elevated pH value of 7.58 indicates alkalosis, as it is above the normal range of 7.35-7.45. The PaCO2 value of 35 mm Hg falls within the normal range, suggesting that the respiratory system is functioning properly. However, the elevated HCO3- value of 50 mEq/L suggests a metabolic imbalance, specifically metabolic alkalosis. This imbalance is characterized by an excess of bicarbonate in the blood.
