Quizplus · Accepted Answer

The ABG values of a pH of 7.49 and a pCO2 of 30 indicate respiratory alkalosis, which is an acid-base disorder. The other options do not provide information related to acid-base balance. LD's pH of 7.49 is above the normal range of 7.35-7.45, indicating an alkalosis or acid-base disorder. None of the other options are specific indicators of an acid-base disorder.
