For items 13 – 19 select the correct interpretation for the given arterial blood gas set. pH 7.51, pCO2 40, HCO3- 31:

The given arterial blood gas set shows a pH level of 7.51, which is higher than the normal range of 7.35-7.45, indicating alkalosis. The pCO2 level is within the normal range of 35-45 mmHg, suggesting that the respiratory system is not compensating for the alkalosis. The HCO3- level is elevated at 31 mEq/L, confirming a metabolic component. Therefore, the interpretation of "Uncompensated metabolic alkalosis" is correct.
